Brief Description Of The Characteristics And Advantages Of Overhead Power Lines
Overhead power lines are a type of electrical transmission system that is used to transmit electrical power over long distances. Unlike underground cables, which are buried beneath the ground, overhead power lines are supported by poles or towers and are visible above the ground.
Overhead power lines are an essential component of the electrical grid, providing a safe and efficient way to transmit electricity from power plants to substations and other distribution points. They are typically used for transmitting electricity at high voltages, typically between 66 kV and 765 kV, in order to reduce energy losses over long distances.
Tumblr media
One of the key advantages of overhead power lines is their low cost. Compared to underground cables, overhead power lines are relatively inexpensive to install and maintain, making them a cost-effective option for transmitting electricity over long distances. Additionally, overhead power lines are relatively easy to repair and replace, which helps to ensure the reliability of the electrical grid.
Another advantage of overhead power lines is their flexibility. Because they are not buried underground, overhead power lines can be easily adjusted or relocated if necessary, allowing them to be used in a wide range of applications and environments. This flexibility makes overhead power lines a versatile option for transmitting electricity.
However, overhead power lines also have some disadvantages. One of the main challenges with overhead power lines is the potential for accidents and electrical shock. Because overhead power lines are visible above the ground, they can be accidentally damaged by vehicles, trees, or other objects. Additionally, overhead power lines can pose a risk of electrical shock to people or animals who come into contact with them.
Another disadvantage of overhead power lines is their potential impact on the environment. Overhead power lines can be visually obtrusive, causing aesthetic concerns for people living in areas where they are installed. Additionally, overhead power lines can interfere with the flight patterns of birds and other animals, potentially causing harm to wildlife.
Despite these challenges, overhead power lines are an essential component of the electrical grid, providing a safe and efficient way to transmit electricity over long distances. With careful planning and maintenance, overhead power lines can be used to reliably and cost-effectively transmit electricity to homes, businesses, and other locations.

Steinkirchen - A Village Full of Warmth
Steinkirchen - A Village Full of Warmth
The sun was high in the sky as Marcus drove his car through the idyllic streets of the sleepy village of Steinkirchen. With its 1822 inhabitants, Steinkirchen was a small gem in the Stade district, nestled in the Altes Land, the largest fruit-growing region in Europe. The community was situated directly on the picturesque Unterelbe and the Lühe, between the cities of Stade and Hamburg.
Marcus was impressed by the peaceful atmosphere of the village. Every other passing driver greeted him warmly, and the villagers always seemed to have a smile on their faces. Marcus decided to explore the area further and parked his car on the main street.
He strolled along the road and noticed Jan, the village policeman, engaging in friendly conversations with passersby. Marcus greeted him and received an equally warm response. Jan told him that in his free time, he enjoyed taking his boat for a little tour on the Lühe, which led directly towards the Elbe.
Marcus continued his walk and was greeted warmly by almost every villager he encountered. The hospitality of the people of Steinkirchen was remarkable. He heard about the St. Martini et Nicolai Church, a famous structure in the village that housed a world-renowned Arp Schnitger organ. He also learned about the Hogendiek Bridge, a charming pedestrian bridge over the Lühe that made the way to Steinkirchen more accessible.
As Marcus continued to stroll through the village, he noticed the imposing overhead power line masts towering along the Elbekreuzung 2 in Steinkirchen. It became clear to him that these masts were the tallest in all of Europe.
As he passed by the Lühe School Center, Marcus heard some sad news. The caretaker of the school center had a fatal accident on the main street. The news quickly spread throughout the village, and soon the entire community gathered for the funeral. It was a moving moment in which the residents showed their grief and support for one another.
To lift his spirits, Marcus thought about the famous personalities connected to Steinkirchen. He remembered Gerdt Hardorff, a painter and graphic artist who was born in Steinkirchen and left behind a creative legacy. Johann Jacob Cordes, an educator and local historian, was also born in this village. Fred Tödter, better known as Tetsche, a renowned illustrator, cartoonist, humorist, and author, had made his home in Steinkirchen. And let's not forget Dörte Hansen, a renowned writer who had lived in this village for over 10 years.
With all these thoughts in mind, Marcus left the village of Steinkirchen. He was impressed by the warm atmosphere and the sense of community that prevailed in this sleepy little place. It was a place where everyone knew each other, and no one was treated as a stranger. Marcus knew he would come back to experience the tranquility and friendly faces of Steinkirchen once again.

Too many of my neighbours have gotten themselves caught up in a false idea of success. White picket fences. Two-point-three-five children. A career that advances. All of these things are impossible now, for a variety of reasons that all rhyme with the sentence "rich people said no."
That's what we in the engineering world call "a constraint." Engineers are used to rich people getting upset about things like properly bolted-on fenders, fully-welded roll cages, and not having a big ol' hole in the side of the space shuttle. They want to hold onto as much of their ill-gotten blood money as possible. Your job is to subtly undermine them, working around the specific letter of their wording to implement the best shit possible. This is because everyone knows that if anything goes wrong, your ass is the one that's getting in trouble instead of Uncle Pennybags.
So, how do we make irrelevant the fact that the limitless promise of capitalism is, at best, an illusion? Getting real weird with it is my usual choice. Human creativity can come up with any number of totally unprofitable but somewhat enjoyable endeavours that you can be doing, instead of work for The Man.
Sure, they're gonna catch you and yell at you for doing things like "spot-welding together some reclaimed yard-lantern batteries on your company-approved ergonomic productivity pod's work-surface." Take heart: HR had to learn a whole lot of words to write up that complaint. They are irreversibly changed by that encounter. Maybe one day, the trauma will resurface in a strange way, and they'll start collecting old tractor tires, building a model train layout, or throwing tinfoil-wrapped rocks at the Amazon drones charging on the overhead power lines. That can be your legacy. Now isn't that a lot better than having to remember how to maintain a lawnmower?

On his knees staring down the barrel of a loaded gun with a mouthful of blood, he knows this is the end of the line. He’s going to die like a rat in the gutter - no mercy to be found, loopholes to exploit or bribes to be made.
This is the real deal, and there’s no coming back.
Judgement Day comes in the form of a man with dark eyes and a dangerous smirk: Golden, the deadliest guard dog of the underground.
Credited with dozens of hits, you won’t know he’s there until it’s too late. Trying to keep him pinned is like trying to catch smoke with your bare hands, or a whisper on the wind.
And you won’t know he’s coming until you feel the breath on the back of your neck, hear the crack of a bullet ringing in your ears.
Belonging to one of the most powerful men in the world: Kim Namjoon, he’s more war machine than man.
“Go ahead, do it!” He spits at Golden’s feet, a mess of blood and drool staining the crisp leather of his combat boots. “Killing me won’t change a goddamn thing.”
A coy smile tugs at Golden’s mouth, his grin all sharp teeth and violence. He stays where he stands, his silhouette haloed by distant streetlights.
Water laps at the docks, the tang of salt heavy in the mid-summer Seoul air. There’s no rush; they both know he’ll be dead and dumped just like all the rest of the garbage in this rotting city.
“Come on, you prick! Pull the fucking trigger already.”
Golden cocks his head, and hums in the back of his throat. 
“Tch! I hope you’ve got a lot of bullets - we’re gonna knock the crown off Kim’s head one way or another.”
Golden thumbs at the safety of his gun, the barrel glinting through the shadows. “Ahh, is that what you think?” He shrugs, a lazy ripple of muscle. “Well, I have to say: I’d love to see you try.”
The night is shattered by the resounding crack of a gunshot and an echoing splash of something heavy dropping into the water below.
Tumblr media
You climb out of the nondescript government-issue car. The faintest tremble of your fingers nearly gives you away but you’re able to reign in the impulse to smooth your hands over your clothes at the last second.
Showing weakness is the last thing you need to be doing right now.
Especially here.
Right in front of where you’ve parked - shoved between two looming apartment complexes - sits a quaint, vintage building. The rough brick face is at odds with the sleek surroundings, but tinted windows keep prying eyes at bay while the classy signing hanging above the door reads The Red Bullet written in caps.
If you didn’t know better, it would be hard to believe this otherwise mundane storefront is a cover for one of the most dangerous international organizations based out of South Korea.
Not only do they hold the keys to the kingdom, but their success is largely in part because they spearhead operations from government espionage all the way to simple blackmail.
Even though it’s been several months since you darkened its doorstep, the familiar sight is enough to steal the breath from your lungs. Send your heart galloping into a tailspin as your stomach swoops.
While time away helped clear your head of stolen kisses and promises whispered in dark rooms, it also drove the longing bone deep.
In those quiet moments to yourself, when you have nothing else to distract from how lonely you are, you miss this place like one misses a limb.
You didn’t realize how attached you were to these four walls until it was too late: the hazy air filled with whorls of smoke, the overhead lights that bathe everything in red, the plush chairs you spent many nights sprawled across, the glossy black stages.
You don’t know how, you don’t know when but at some point it (he) started feeling like home. A luxury you can’t afford. Not again. After all, if you give in, any progress you made outside of his gravitational pull will be for naught.
Which puts you in a dangerous position as you find yourself back where it began; feelings at war with duty, mind vs heart. Because even if it leads you to a place you could go a million years without ever seeing again, you have to follow the trail of bodies.
A bouncer grants you access, the heavy door slamming shut behind you like a death knell as he herds you towards the back of the club.
It’s outside of official operating hours but it’s no less busy inside, men and women alike in scattered conversation as you pass through.
“It’s nice to see you again,” the bouncer murmurs, chancing a quick glance at your profile. “Been a while.”
You swallow, gaze darting down to your shoes. “Ah - yeah… Got busy with work. It’s - it’s nice to see you too.”
The small talk fizzles out, a snuffed candle as you arrive at a cordoned off room, “Here we are. Mr Kim is already expecting you.”
Any further pleasantries grow stale on your tongue as you enter the private booth, fighting against the lump in your throat to manage a hoarse ‘thank you’.
And then you find yourself left alone with the man himself, Kim Namjoon. He’s as intimidating as you remember, lounging back into the leather booth with his ankles crossed.
A lukewarm smile stretches across his lips, the slightest hint of a dimple peeking out from the valley of his cheek. Standing at attention on either side of his reposing form are two massive bodyguards. Their hands rest on the butts of their guns, daring any who enter to try and make a move.
“It’s good to see you again. But I gotta ask - what’s the occasion, Detective?” Namjoon hums. “I thought we were past all this.” He waves a nebulous hand between your bodies. “After all, you’re practically family.”
You ignore the hidden barb with a wince. “Mr Kim, you know why I’m here.”
“I used to know why a long time ago.” A well-groomed brow raises, his gaze glacial as it spears you in place. “But now I’m not so sure.”
“Please, Mr Kim. I don’t want to make this more difficult than it is. I just need to know about the man they fished out of the harbor, and then I’ll be on my way. So… who was he?”
Namjoon scoffs. “What makes you think I know more than the police?”
There’s a flash of a smirk, barely noticed, before his face returns to its neutral expression. As calm and cool as a placid river. “A john’s a john. What I do want to know is why you care so much?”
The underlying question is clear; why are you really here?
“I’m afraid I’m not at liberty to discuss such matters with civillians.”
“Oh? So I’m a civilian now.” His expression is not unlike the cat that caught the canary: vicious and delighting in the discomfort his evasions are causing. “Gotta say that’s a new one for me.”
Sighing in defeat, you say, “Alright, enough. I get it. I’m wasting my time with you. Let me ask this instead: where is he?” 
“He doesn’t know any more about this than I do,” he says, waving a blase hand towards a door off to the left, “But if you insist, you can find him in the office. Oh, and Detective?”
“...Yes?”
“Take your time, I’ll be out on business all afternoon.”
With a curt nod, you flee the room amid low-throated chuckles and enter the office. Standing near the desk, his broad back turned towards the door, you find the man you simultaneously want to see the most and run from the fastest.
He turns around, the muscles of his back rippling with the movement. Your breath stutters in your chest, and you nearly swallow your tongue as your eyes trace over the cut of his body.
The moment your eyes meet, those many months spent cultivating time and distance turn to ash. You forgot how even the mere sight of him affects you, any resistance to his many charms virtually nonexistent as the world falls away.
Rich, coffee dark; his gaze sucks you in until it’s all you can do not to reach out, to brush your fingers over his edges and feel them soften beneath your palms.
Rocking back on your heels, you clear your throat and glance to the side as you remain standing in the entryway, more than a little off-kilter.
Coming back after so long apart, only to find him the same as the day you left… How do you reconcile everything that’s changed with everything that was?
“Well, hello there.” Jungkook croons, leaning his hip against the corner of the desk with a roll of his shoulders. His arms cross over the trunk of his chest, accentuating the bulk of his chest, the flex of inked bicep. “Long time no see.”
Shifting, you gulp. “Ah - yeah…”
The burn of his gaze - a palpable sensation prickling across your skin - tracks a path from the crown of your head to the tips of your toes as he gives you a thorough once-over.
“You’re looking good,” Jungkook hums in approval, “real good. I’ve missed those pretty eyes of yours.”
“You - you too.”
Your attention doesn’t know where to settle: drifting from the curve of his shoulders to the jut of his bloody knuckles, the tuck of his trim hips to the thick-soled combat boots.
Tiny hairs at the back of your neck stand on end, and your palms slick with sweat.
“I mean, you look… y’know, uh, good too.”
A flash of a crooked smirk, the raising of a pierced brow gets your blood pumping, your heart tattooing a rhythm against your ribs. Emboldens you to reach back with shaky fingers to turn the lock. The sound grates down your spine, bolts of anticipation slicing through you.
It was dumb to think coming here, seeing him again, would end any other way than his taste on your tongue and his cock in your cunt. Hope makes fools of us all.
Should’ve known better but you’d been hopeful those days were long behind you. Now you realize it was inevitable.
After all, Jungkook is magnetic.
The black hole at the center of your universe, consuming everything in its path until he’s what remains in your head, your heart. You’re helpless, ceaselessly drawn to him like a moth to flame.
And try as you might, you can’t say no to a face like that.
Never could, in fact.
Failure to extract yourself from his orbit during your not-relationship is nothing new. That doesn’t mean you can’t make it difficult.
After all, you still have some dignity intact.
So try, try, try again.
“Ahem.” You try to banish the heat from your cheeks, guiding the conversation into the correct territory. “I’m not here on a-a social call, Jeon. I need to know: were you the one that killed and dumped the john in the harbor?”
Stalking closer, a lazy jungle cat on the prowl, Jungkook crosses the distance between you. He only stops once your bodies brush with every labored inhale. Heat radiates from him, and you’re achingly aware of every point of contact.
The light scent of his cologne teases your nose, and his eyes - god, his eyes. They’re shaded and hungry, devouring your expression with single-minded possessiveness. 
“What makes you think I know anything about that?”
“Jeon -- Jungkook.”
He hums.
Your heart thrums, pulse rushing hard through your head until you feel faint, blood surging the longer you stay in close contact. The shameful clench of your cunt makes your cheeks burn all the brighter.
The last time you were looking up at him like this, his hand was on your jaw while his cock thrust balls deep.
“C’mon, you know that isn’t going to work. This is me you’re talking to, not some rookie.”
“Mm,” he purrs, “it is you I’m talking to, isn’t it?”
You manage to bite back the groan but can’t stop your eyes from rolling even if there’s the slightest hint of a stutter when you reply, “Please, I just need to know if you killed him.”
Jungkook looms tall and proud, crowding closer. “And if I did, baby?” he asks.
Instinctively you back up, only to be followed step by step. A game of cat and mouse that finds you pinned against the wall before long. With nowhere to run, you watch, heart in your throat, as Jungkook dips his dark head.
His nose runs along the length of your neck, breath puffing across your sensitive skin as he inhales the pleasant scent of your perfume.
“I - I…”
“Would you see me in handcuffs?” His lips caress the underside of your jaw, a soft groan escaping him. “… C’mon, answer me. Would you?”
“I would - if I had to.”
As much as you wish that was true, you know in your heart of heart's you would do everything in your power to make sure that never happens.
No matter how much you like to think you’d do the right thing when push comes to shove, you’d choose him a thousand times over.
His eyes dance playfully. “Careful, I might like it.”
“I can’t say I’m surprised,” you say with a snort.
Jungkook chuckles low and warm, using the arm around your waist to tug you into the safety of his body. The softness of your breasts presses into the hard planes of his chest, your nipples pebbling through the thin cotton shirt you wear.
With a deep-throated groan, his hands encircle the curves of your hips as a thickly muscled thigh slots between yours.
An answering quiet sigh gets his blood pumping and his cock twitching.
“Mm, something tells me you’d enjoy it just as much, Detective.”
The use of your title is a rude awakening.
“Jungkook,” You warn, moving to push him away. Only once you start touching him, you can’t stop. His muscles flex beneath your curious fingertips. “We really shouldn’t.”
You’re sure if he could, Jungkook would spend days worshipping between your thighs, velvet heat wrapped around his tongue and hands in his hair as he brings you to peak again and again until you’re a sobbing, sopping, boneless mess beneath him.
“Come on, I know you want me - that you’ve missed me. I can see it in your eyes.”
He kisses the corner of your mouth, tongue flickering out for a brief taste before a rough thumb skates across your bottom lip, tugging down to expose your teeth, the glitter of your tongue as it darts out to flick over the pad of his finger..
“I’ve certainly missed you, baby. Want me to show you?”
Even though you refuse to admit anything out loud, you can’t help but angle your throat back and grind into his hips pressed against yours.
Jungkook tsks, “That’s alright. I’ll get that pretty mouth open one way or another.”
Before you can retort, a mouth swoops down to fuse with yours in a fierce, all-consuming kiss. A low, broken moan punches from your chest.
Reaching up, your fingers sink into the mane of dark hair that brushes the cut of Jungkook’s jaw. Soft, thick, and wavy in your grip; you tug at the roots.
Jungkook hisses. 
Teeth nip at your lip, kittenish licks soothing away the string as blood bursts across your tongues. The thigh shoved between yours grinds up with every wet, sloppy pass of your lips.
Thick muscle spreads your pussy open through the thin slacks of your work uniform. Sparks of pleasure dance down your spine with every rock against your swollen clit.
“S-Shit!” Your shoulders curl in, a shudder jerking through you. “K-Kook, I… !”
“Fuck, you’re so wet for me.” Jungkook growls, rutting his cock against the jut of your hip. The wet patch you’re making on his jeans grows larger with every filthy grind. “You’ve been gone too fucking long. Never again, you hear me?”
You claw at his shoulders, stuttering out, “there’s noth-ing you can do t’stop me.”
“If you don’t come back to me,” his eyes are dark and stormy, voice whiskey rough, “I’ll find you.”
It’s not a threat - it’s a promise.
“Then make sure I never want to leave,” you challenge breathlessly, staring into his blown out pupils, “Make me want to stay.”
Above all else, you think.
The words are barely past your lips when Jungkook accepts your challenge with gusto (just like you knew he would). Without delay, he thumbs open the button on your pants.
Refusing to let you look away, Jungkook yanks them to your feet and swings you up into his arms one-handed. They hang from your ankle like a chain.
Your surprised squeak is quickly swallowed up by a moan when he settles you over the bulge in his pants, your cunt hovering over his erection.
The heat of his skin sinks through the thin cotton of your panties, so, so close to where you need him. Slick soaks into the fabric, and clings to your inner thighs.
Every shift is a smooth, sticky glide of folds that stirs, and stokes the ember of desire smoldering behind your navel.
“Kook,” you breathe. “Please.”
Your head rolls back, and you sag into his chest. Your hips twitch in pathetic little attempts, trying to get pressure where you need it. Having him hot and hard and all for you; any distance between you is suddenly unbearable.
He needs to spread you wide and stuff you full with every inch of his thick cock until he’s so deep you won’t be able to walk for days.
“Shh baby, I’ll give you what you want,” he says, gaze heavy and possessive. “I’m gonna ruin you so good, you’ll have no choice but to come back. You’re mine.”
“Says who?”
“Hmm. You don’t think you are?”
Nibbling on your ear, Jungkook slips a finger under the hem of your panties. He smirks when you keen, rubbing his knuckle up and down your sloppy folds with teasing pressure.
“How about I show you what your body already knows?”
Wasting no time, he lifts you off his cock, the scrap of cloth fluttering to the ground. His free hand dives between your bodies. Then comes the clink of a belt, the sound of a zipper pulling down.
Your heartbeat thunders in your ears, your body coiled with anticipation as your stomach swoops at the brush of his fingers along the underside of your thigh.
“Look so pretty like this, baby.” Jungkook twists his wrist, hips arching back. “And it’s all for me. Fuck, I can’t wait to get inside this pretty pussy.”
Any response dies on your tongue, brain short-circuiting as the slick, fat cockhead rubs along your slit. Pressing against your entrance the slightest bit before slipping up to nudge at your clit - coating himself up in your sticky juices.
The ultimate tease - something Jungkook’s always been overly fond of doing until you’re out of your mind with desperation.
“Please, please, please,” you chant, cheeks on fire and eyes half-lidded as you circle your hips. “Stop playing around. I want it - want you, Kook.”
“Oh, baby,” he smiles, ducking down to kiss your forehead. “You’ll take whatever I give you.”
You can’t stifle the broken sob, tears prickling at the corners of your eyes. Liquid fire surges through your veins, a thousand bolts of lightening crackling beneath the surface of your skin. Your pussy is tender, swollen. Walls fluttering in time with your heartbeat. 
“Ha, you’re so needy for me.”
Jungkook’s lips brush away the moisture around your eyes, his thumb drawing soothing circles into the base of your spine. All the while, his torturous grinding never ceases.
“Aren’t you?”
You croak, “I can’t – Kook, please. Anything, I’ll do anything you want just fuck me.”
The flash of his eyes is your only warning before he’s right there, your walls embracing the girth of his erection inch by inch. Every ridge, every jerk as he seats himself as deep inside your silken heat as he can is absolute heaven.
The stretch as you take him to the hilt sends you careening towards the edge, eyes rolling back and toes curling in your shoes.
“Shit, shit, shit, shit!” you whimper.
“Shit!” Jungkook grits his teeth, squeezing the base of his cock as you tighten  around him. With every deep inhale, his pelvis brushes your swollen, needy clit. “Forgot how good you feel wrapped around my dick, baby.”
“Me too,” You gasp, tightening your legs around Jungkook’s hips.”Me too, Kook.”
Dropping his forehead to yours, he says gruffly, “‘m not gonna last long.”
Making a noise of acknowledgement, you wiggle your hips. Sinking your teeth into the side of Jungkook’s jaw, you bite and suck at his skin, wanting to leave a mark to remember you by. His reaction is instantaneous, releasing the grip on his shaft to grab a fist full of hair.
He yanks back.
The long, elegant line of your throat is exposed to his butterfly kisses and scolding love bites.
“Now you’ve really asked for it,” Jungkook huffs out with a dirty chuckle.
“Then give it to me.” You lick your puffy lips, looking up at him from beneath your lashes. “Show me who I belong to.”  
The brewing hurricane in his eyes is unleashed. Wide palms and strong fingers grip your hips so tight you feel bones grind together. His stance widens, his unwavering gaze locking onto your face, brow pinched, and mouth slack.
His lip piercing glints in the light, his tongue sliding out to wet his bottom lip. Dark curls tussle about his head, a wild halo that sweeps down into the burning umber of his eyes.
Helpless, you succumb - enchanted by the darkness peering at you from behind those dangerous eyes. He’s ethereal; a siren song that threatens to drown you, swallow you whole.
You’d happily let him, you realize with a shiver.
It’s true, he owns you: blood, bones, and all.
“Hold on tight,” Jungkook says, hooking his hands under your bottom. 
And then, he’s jackhammering into your cunt so hard and fast all you can do is hold on for the ride. Punch drunk and moaning as he manhandles you how he likes, spreads you wide and stuffs you full until you’re panting for breath and clinging to sanity by your fingernails.
“Fuck yes, that’s it. Look how well your pretty pussy always takes my fat cock.”
His low voice whispering filthy praises in your ear makes you whimper, whine, and writhe as the band of pleasure coiling tight in your belly comes close to snapping. It’s the fastest he’s ever fucked an orgasm out of you, and it feels so good you don’t even care.
The pace is brutal, slamming into you so hard you’re sure you’ll have bruises on your hips come morning. But it’ll be so fucking worth it. You’re going to cum hard and long, you just know it.
About to melt as Jungkook fucks the slick out of you, groaning as you drip down the base of his cock, his balls - his very own pretty little mess.
“Yeah, you gonna cum, baby?” he laughs, pressing a sweaty kiss to the side of your face. “Can feel how - haaah shit - how tight you’re squeezing me.”
“Uh-huh,” you cry, holding onto the tops of his wide shoulders. Every thrust has his cockhead dragging over the spongy patch of your g-spot, sending fissions of pleasure rocketing through your nervous system. “So - so close, baby. Just a little more, I--”
Balancing yourself, you lift up only to slam back down, meeting Jungkook’s thrust with all the force of gravity. “Oh fuck, oh fuck!”
Crashing over you like a tsunami, your orgasm shoots through your limbs and zips down your spine. A warm rush of cum soaks Jungkook’s shaft, the wet and messy sound of your squirt splashing against the floor secondary to the cry that claws its way out of your throat.
“K-Kook!”
Jungkook grunts, his fingers digging into the fat of your hips as he helps you keep bouncing up and down on his erection. “Yeah, that’s it - keep going, baby. Wanna feel you keep cumming all over this cock.”
Aftershocks slice through you like lightning, tiny jolts of electricity. As you come down from your high, your gummy walls pulse, milking at Jungkook’s thick shaft.
He groans softly whenever your muscles tense, release; your body a worn-out rubber band as your breath stutters from you.
Then a hand pets down your flank, your skin shivering with hypersensitivity at the tender touch. “S’okay. Just breathe, baby.”
Peeling open your heavy eyes, you look up at his face. Take in the crinkle of his brow and the ravenous expression. Even floating on a sea of bliss, white noise fills your ears, you want more.
You slur, determined, “Kook, baby, please. Cum in me, want you s’bad.”
“Fuck! Can’t just say shit like that to me or I…” Jungkook bites down onto the tender crook of your neck, muffling his grunts in your flesh. “Shit - ’m so --”
You cry out, nails digging into the meat of his shoulders, “A-haah, K-Kook!”
Snapping his hips forward one last time, Jungkook grinds as deep as he can get and lets go. The fat head of his cock kisses your cervix, his length throbbing in time with his heartbeat as a rush of cum floods your insides.
“Yeah, just like that,” he grunts, rutting once - twice into the cradle of your body, “take it like a good girl.”
He croons when you whine at the press of his pelvis against your oversensitive clit. Thready sparks of pain shoot down your legs that hang limply over his forearms. Every breath stutters from your lungs, slow and deep.
“No more, can’t - can’t…” Shifting, you arch your spine and burrow your head into his chest, nearly catatonic in his arms. “S’too much.”
“Shh, it’s okay. I’ve got you.” Fingers brush over your closed eyelids, smoothing over the arch of your brow. With every kiss dropped to the top of your head, he mumbles in dulcet tones, “I really have missed you, you know.”
You mewl in response as strong fingers knead the backs of your thighs.
“You’re not allowed to go anywhere.”
“Oh,” you can’t muster up enough energy to say anything more, body tender and trembling with little aftershocks, “s’that right?”
“Yeah, that’s right.” He chuckles. “You’re staying here - right where I want you.”
In lieu of a response, you pick your head up off the pillow of his chest and seek out his gaze. Liquid soft; he’s looking at you like you hung the world on a string.
“I’ve missed you too, Kook,” you say with a gentle smile.
You’ll allow yourself this moment of weakness when there’s no space between your bodies or hearts. Titles don’t matter much when he’s cradling you to his chest like a piece of precious china.
Between the two of us, you’re the one who hung the moon and stars, you think while combing back his sweaty bangs.
And I think I love you, you whisper voiceless against his lips.

project aphrodite
rating: explicit
member: jungwon
premise: in a post-apocalyptic world, you and jungwon are excellent scientists and are at the relative top of the list of people who are ideal parents for the next generation of this dying world. it's now your job to repopulate this earth so you ask your co-worker to pretty please knock you up.
notes: sci-fi elements, dystopian au, scientist!reader, scientist!jungwon, fem-bodied reader, reader is referred to as a woman, dom!jungwon, breeding, impreg kink (like heavily), dirty talk, platonic (?) breeding, co-workers with benefits (?), idk this is kinda speculative fiction but also suspend your disbelief a bit lol
a/n: first of my 1k follower special! not quite sure what order i'm following here but i hope you stay for the ride nonetheless! enjoy!
Tumblr media
it's a strange feeling.
in your line of work, 'strange' is hardly any cause for concern. as a biologist with a concentration in genetics, you've seen all the ways nature does its job. from the familiar concepts almost all people learn about in science class like the basic 'mom-meets-dad-equals-baby' to the eerie methods organisms in the deep sea evolve to survive.
you've learned about it all, pored over each punnett square, stressed over the formulas. so, this shouldn't be anything to worry about.
and yet, you're still worried.
"i mean...what did we expect?" jay speaks up from beside you, eyeing the phone in his hand.
"we're presently some of the world's most brilliant minds so...," he adds, locking his phone before hunching over his desk. to your ears, it sounds as if he's trying to convince himself rather than you.
you scan over the document flashed on your own laptop screen. the harsh fluorescent lights overhead buzz nonstop, going on and on, a background hum all of you in the bunker have grown used to. at this moment, it lulls you into a daydream, vision swimming as you repeat the words in your head.
all government personnel with a status level 7 and higher are recommended to partake in project aphrodite. those falling under level 10 are strictly required. participation at this level is compulsory.
common citizens with a status of 9 to 10 are also required to participate. ample compensation for those successful will be provided.
"you're a level 8. it's not as if you have to," you mutter, fingers digging into your temples.
jay snickers. "how many level 10 government personnel are there in this ruined world? a few hundred or so doctors, another few hundred scientists, even fewer world leaders. that's not taking into account the difference in sex. my information's not up to date but last time i checked, there is a hell of a lot more men than there are women. it's a shitshow waiting to happen."
you turn to meet jay's eyes, not meaning to convey any certain emotion, but the way jay's expression falls leads you to believe that you look way more upset than you're letting on.
"oh shit, yeah," jay curses. "you're a level 10. i forgot."
you sigh, tilting your head back against the headrest of your seat.
"i'm sure they'll release more regulation soon," you begin. "this is just the initial memo. with our world hanging in the balance as it is, no one's gonna let this devolve into some patriarchal anarchy, i hope."
"yeah, of course," you hear jay agree. "most of the proponents of project aphrodite are women, anyway, so i'm sure they'll take extra measures to keep you safe."
you sit up straight, looking at jay once more. "this is the world, huh?"
you and jay pause before sharing a quick chuckle.
"'go make babies, or else,'" you say in a mock radio announcer voice. jay lets out a laugh, his voice echoing off the empty office walls.
the two of you fall into silence, as if retreating to your respective thoughts. all that's in your mind at this moment is your current project, the very thing the few people more powerful than you had assigned for you to do: leading your team in stopping that godforsaken virus ravaging the outside. you've been making steady progress so far, but with the weight of this new responsibility, you're not sure if you could keep the momentum up.
you realize with a passing thought that most of the scientists on your team are level 9s and 10s.
"well," you begin before you could stop yourself. you're suddenly overcome with a feeling of suffocation, the office space seemingly too small and continuously growing even smaller.
"i hope you find someone you'd like to procreate with," you say lightly, pushing yourself off your chair. you quickly gather your things: folders and binders and other loose papers in your arms.
you catch jay looking at you, a pensive look on his face. you stop as you're grabbing your reusable coffee jug.
"no," you deadpan. "not me."
jay's eyes widen, as if realizing he'd said something without really saying anything.
"i—no, wait—i mean...," jay stutters, ears quickly turning red.
you smile, patting jay's shoulder reassuringly. "in case you were thinking about it."
jay's mouth opens and closes like a fish out of water and you can't help but laugh.
"these are desperate times, but i'm hoping it's not too desperate," you add. without waiting for a response, you turn towards the door, already making your way to it.
"besides, dr. isa lee seems more your type," you say over your shoulder one last time before pushing the door open and stepping out into the hallway.
---
"hey."
you look up from the microscope, tearing your attention away from the specimen you were examining. your eyes readjust to their normal focal length as a tall figure enters the lab, perfectly crisp white coat hanging off his broad shoulders, thin-wired spectacles resting on the bridge of his tall, straight nose. your lips feel strangely parched as he makes direct eye contact with you and you're left with no choice but to moisten them with your tongue.
"oh hi, dr. yang."
the other scientist chuckles, setting down a stack of papers on a desk in the corner. "i've been here for three weeks. please, call me jungwon."
you swallow. "right. jungwon."
dr. jungwon yang was a new import from the seoul bunker, having come to your own area's bunker merely a few weeks prior. he was immediately put under your supervision, an addition to your already elite team of biologists, geneticists, and virologists. off the bat, you could tell he was a man of many talents, coming up with unconventional solutions and arriving at answers quicker than anyone else.
his presence in your lab made your heart swell. in pride, adoration, or desire, you're not quite sure.
"uh, yesterday's results are in that binder over there, in case you want to go over them," you begin. jungwon walks over to your side of the long table, peering over the slide loaded into the microscope.
ignoring the way he brushes ever so slightly against you, you continue. "the director's dropping by later this afternoon, but i wouldn't be too bothered with that. he's just looking for someone to blame for the slow progress at this point. if only they could get us those materials we asked for..."
"have you read the memo?" jungwon asks abruptly, straightening up. he towers over you, his eyes downcast as he stares at your face.
"of course, you've read the memo," jungwon corrects himself, chuckling. "what i meant was...what do you think of it?"
"it's a government-issued memo, it hardly matters what i think," you respond, focusing back on your work in front of you, although all you do is stare blankly at the moving microorganisms, mind unfocused with how much of jungwon's perfume you can smell.
"it's your reproductive health that's on the line. i'm pretty sure your opinion counts for something," jungwon says with a pinch in between his eyebrows.
oh, a feminist. that's even hotter.
"okay, yeah. i appreciate the new guidelines they put out," you admit, looking back up at jungwon. "though it's the bare minimum, i'm glad they're letting us keep the autonomy of choosing who to...boink."
jungwon laughs at that.
"and free fertility drugs for anyone who wants or needs it. oh, also, thank god they didn't have the brilliant idea of putting a time limit on it. having read some crazy speculative fiction myself, the things people are willing to do in fiction are crazy. who's to say they can't do the same in real life?" you continue.
you don't notice the way jungwon's smirk grows as he listens.
"kind of makes the whole thing unsexy, don't you think?" jungwon cuts in, raising an eyebrow. you blink, unsure of what he's talking about.
"i'm surprised they're not monitoring us with cameras and hooking us up to EKGs and shit," he adds.
"oh," you say with a soft giggle, finally catching on. "i'm sure some people are into being watched."
"are you?" jungwon asks.
"am i what?" you answer.
"into being watched."
a pause.
you shake your head. "how about you?"
"oh no," jungwon says. "i prefer to keep what's mine for my eyes only."
"hm. possessive. that's kind of sexy," you mumble under your breath, a sudden surge of confidence coursing through you.
jungwon just stares at you, but you can see his pupils dance in amusement, taking in your whole face and all your features. you might have imagined it but he seemed to have peeked down at your chest for a second.
"do you think it's attractive for someone to be into lego-building? or at least, used to be into it. i'd give an arm and a leg for a complete lego set nowadays," jungwon asks, leaning against the table, and only now do you notice the veins running over the back of his hands.
you think about whether his arms are just as veiny.
"do you think it's a good trait to pass on an offspring? lego-building, i mean," he presses on.
"uh, yeah. good problem-solving skills," you answer, humoring his question.
jungwon nods. "do you think leadership skills are important?"
you smile, leaning against the cabinet opposite jungwon. you nudge his foot lightly. "i lead a team of scientists myself. of course, i think leadership skills are important."
"you and i both," jungwon agrees.
jungwon shifts, placing his hands in the pockets of his lab coat.
"how about dimples? do you think dimples are cute?" jungwon asks once more, one corner of his mouth upturned. a deep crease on his cheek appears.
a dimple.
"very," you admit.
"i see."
there's a silence that stretches over the two of you, and the weight of uncertainty is daunting as you stare at a spot on jungwon's tie. finally, after a few seconds, you heave a sigh, unable to take the tension any longer.
"this is the weirdest way anyone has ever flirted with me," you declare, looking up at jungwon through your lashes. he's grinning and you nearly shiver at how utterly attractive you're finding him at this moment.
"but it's effective," jungwon says. that was a statement, not a question.
you tilt your head to the side. "how do you know?"
"because you would have blown me off two minutes ago if it wasn't," jungwon reasons, crossing his arms. by doing this, he just made himself appear even wider than he is.
"always so calculated," you say, impressed.
you stretch your neck, easing your head from side to side, watching as jungwon fixes his gaze on the taut tendons of your neck. "are you also this precise in bed, dr. yang?"
jungwon approaches, a large hand resting on your hip. "that's for you to find out."
your breath hitches as you feel his thumb rub through the fabric of your skirt.
"later?" he asks.
"my place or yours?" you reply, fingertips grazing the front of his polo. you can just about feel the slope and ridges of his toned muscles.
"i'd like to be a gentleman, so mine," jungwon offers. "i'll walk you back to your room after."
"i was kind of hoping i wouldn't need to walk back after," you say, a hint of teasing in your voice.
"is that a challenge?" jungwon says, his other hand pressing firmly on your lower back. he pulls you to him and your hands involuntarily reach out towards his shoulders to steady yourself.
a few seconds pass before any of you speak again.
"that's for you to find out," you say.
---
"kind of weird, isn't it?" jungwon asks, panting against your neck.
your back is pressed firmly against one wall of his sleeping quarters, a wide, loft-like room, similar to yours. a luxury offered only to level 10 government personnel, the room gives its occupants enough space and enough privacy.
and boy, did you need privacy.
"what's weird?" you say breathily, fingers threading through jungwon's hair as he kisses down the column of your neck. his fingers nimbly undo the buttons of your blouse and you whimper when you feel him lick at the valley between your breasts.
"coming up to coworkers or friends then asking them to reproduce with you," jungwon responds, tugging your blouse off of your shoulders.
(you both held enough respect for the institution that employed you both, so your work lab coats were neatly thrown over the back of jungwon's couch before anything got too frisky.)
"see, it's the way you say it that makes it weird," you giggle. you pull jungwon back up to your face, kissing him fervently, tongue licking into his mouth.
"oh yeah? how would you say it?" jungwon challenges as he pulls away slightly, his nose grazing your cheek. he licks a stripe on the underside of your jaw.
"please, jungwon," you whimper, playing up the whine in your voice just a little bit. "need you to knock me up. make me pregnant, please."
jungwon grunts in your ear, reaching behind you to rip the zipper of your skirt down. you let the fabric fall to the floor, stepping out of it quickly, revealing the matching red lace panties you had in tandem with your bra.
"yeah? want me to cum inside you so many times that there won't even be the tiniest chance that you're not pregnant?" jungwon says lowly, kneading one of your boobs in his hands.
you nod, hooking a leg around jungwon's hip, pushing your core right up against the bulge in his pants.
"yes," you breathe out, dragging your clothed pussy over his straining cock. "let's be good citizens and have a whole bunch of kids, yeah?"
jungwon chuckles, hands hurriedly working on his belt. you take this time to kiss up his neck, still rutting against him, desperate for any contact.
"come here," jungwon says through gritted teeth as his pants and boxers fall to the floor. he kicks them off unceremoniously, yanking you towards the couch. your eyes briefly catch the flash of white that were your lab coats.
the two of you fall onto the cushiony surface, with jungwon sitting up and you falling a little less gracefully on him. the two of you laugh as you adjust yourself, righting your posture so you could look at jungwon.
"take this off," jungwon commands, pulling at your panties. you swing off jungwon for a moment, pulling off the garment in record time. you reposition yourself over jungwon, his cock standing tall, hard, and painfully red.
"come on, show me how bad you want those kids," jungwon teases, tucking your hair behind your ear.
you roll your eyes. "you gotta help with the diapers."
a second later, you sink down on jungwon, moaning wantonly at how much he stretches you out, filling you up effortlessly. jungwon throws his head back, his bottom lip pinched between his teeth.
"i'll quit my fucking job at the lab if this is how good it feels to make babies with you," jungwon groans, his fingers digging into the flesh of your hips.
you whimper at his words, rocking back and forth on his lap. you angle your hips a certain way, the tip of his cock kissing at just the perfect spot inside you. you shudder, repeating your movement.
"god, you feel amazing," jungwon praises. "so warm, so tight."
"yeah," you respond. you're gliding up and down his cock, swiveling your hips as fast as you can. you clench down around him, the thought of jungwon cumming inside you your only motivation.
"filling me up so good," you add, watching as jungwon screws his eyes shut, neck shiny with sweat.
you move forward, attaching your lips just below jungwon's ear. you suckle on the salty skin, running your tongue over the spot, savoring the way jungwon lets a moan rip out of him.
"gotta let the whole bunker know this one's mine," you whisper as you let up on jungwon's neck. a faint red spot is left in the wake of your lips on his skin.
in a blink of an eye, your whole world tumbles upside down, jungwon's hands forcing you down on the couch by your waist. in a daze, you realize that jungwon has you pinned under him, his eyes wild with a hungry look in them. he pushes your legs right up against your chest, lining himself up with your entrance.
"the moment you start showing, no one in this goddamn bunker will have a single doubt who gave you that baby," jungwon counters, thrusting into you. he gives you no time to adjust, picking up where you left off.
you cry out, trying to anchor yourself on anything your hands can find. eventually, you find purchase in jungwon's shoulders. he feels your nails digging in, and he mutters a soft 'fuck', speeding up his movements, the wet sounds of his skin slapping against yours so incredibly obscene in the confined space of his room.
"give it to me, please," you say, meeting jungwon's eyes as he continues to fuck into you. his forehead is creased, a look of concentration washing over his face.
"cum inside, fill me up as many times as you want, fuck it deep in me," you continue, cradling jungwon's face in your hands, the tender gesture a contrast to how rough he's bein.
"god," jungwon groans, voice breaking at the end as he speeds up, but then he halts abruptly, his mouth hanging open in a silent moan. you feel him twitch inside you and you gasp, clenching down as hard as you can.
"fuck, yes, milk it all out," jungwon says. he starts to thrust up into you again, watching as his cock is slowly coated with his cum spreading all over your cushy walls.
you whine, your fingers finding their way down to your cunt, your middle and ring finger pressing onto your clit. you rub at it ferociously, the idea of jungwon's sticky release inside of you turning you on impossibly.
"i'm getting hard again, jesus christ," jungwon complains but his movements don't cease. he's shaking from the overstimulation but he wraps his arms around you, pulling your limp form up against him.
"rub that pretty pussy for me, babe," jungwon requests, thrusting up into you shallowly.
"make yourself cum while i fill you up for a second time."
---
"so?"
you jump a little at the sudden intrusion. you look up at jungwon through both of your reflections in your bathroom mirror. three pregnancy tests lie in a neat line on the edge of the sink.
"i just started the timer, jungwon," you reply with a laugh. jungwon turns you around to face him, kissing you briefly.
"hm," you say, looking up at jungwon questioningly. "you never kiss me unless you want something."
"well," jungwon begins, hands slipping under your sweater. "we can always kill time while we wait for the results."
you shake your head, but you're already pressing yourself up against jungwon. "you're insatiable, dr. yang."
jungwon winks at you, undoing your bra under your shirt. "you know it."
"plus, you just look too good in this damn lab coat."

2022 Future Trends in the Cable Industry: High Capacity, Underground and Energy Efficiency
The wire and cable industry underpins the functioning of modern economies and societies. This report focuses on the 10kV and above cable industry and highlights high capacity, underground, and energy efficiency as future trends in the cable industry.
Tumblr media
Cables of 10kV and above are mainly used in power generation, transmission, and distribution, as well as in some large industrial and commercial buildings. In terms of technical form, 10kV and above cables are currently available as overhead lines, underground cables, and GIL (gas insulated transmission lines).
Each of these three technical solutions has its advantages and disadvantages. The main advantage of overhead lines is that they are cheap and the disadvantage is that the support facilities take up a lot of space. Underground cables have the advantage of not taking up much space, but the disadvantages are that points of failure are difficult to detect and the insulation is susceptible to deterioration, while the advantages of GIL are that it performs well and does not take up much space.
It is expected that these three transmission methods will continue to be the primary means of building the power grid and supporting the construction of large-scale power systems.
1. New Conductors Increase Transmission Capacity of Overhead Lines
Because the overhead transmission system relies primarily on air insulation, it is the most common solution for high-voltage transmission away from cities because of its low cost, large area, and high capacity. Lines of 750 kV and above will be used almost exclusively for very high voltage transmission projects over long distances. With the acceleration of new power system construction, the overall demand for grid transmission capacity is expected to accelerate.
Recently, MarketsandResearch.biz published the "Global Aerial Bundled Cable Market 2022 by Manufacturers, Regions, Type, and Application, Forecast to 2028." The report forecasts steady growth for aerial cables by 2028 for the leading companies in the cable industry (Nexans France, ZMS Cable Group, EMTA Conductors and Cables, etc.).
The future trend for overhead lines will be to increase capacity. New construction projects can be more energy-efficient conductors, and already built projects can be upgraded with additional capacity.
(1) Energy-saving wire for new projects, saving transmission losses.
Traditional wire for aluminum strands with a steel core. To improve the overall conductivity of the conductor and reduce losses, the usual idea is to improve the conductivity of the outer section of the aluminum strand or use a higher conductivity of the carrier core.
The outer stranded section can be made of a hard aluminum alloy with high conductivity (61.5%-63% IACS) or soft aluminum (63% IACS). However, due to the low tensile strength of soft aluminum, a stronger carrier core, such as a carbon fiber composite core, is required. Since soft aluminum also has excellent high-temperature resistance, it is more suitable for capacity-building projects.
For the load-bearing part, a high-strength aluminum alloy core (52%-55% IACS) can be used instead of a steel core. This results in a higher conductivity of the aluminum alloy core strand, which also has excellent tensile strength. Therefore, new projects mainly use energy-saving conductors with high-conductivity aluminum, aluminum alloy, or all-aluminum alloy cores.
Tumblr media
(2) Capacity-added conductors are suitable for existing projects and are extremely cost-effective.
Theoretically, there are two main methods to increase the capacity of constructed lines.
(1) By replacing the conductor with an overhead conductor of the larger cross-section. However, increasing the cross-sectional area of the cable greatly increases the total weight of the overhead conductors, making them unviable for electrical towers. Therefore, a new electrical tower would have to be rebuilt. This method involves high investment, a long construction period for reconstruction, and a very low overall cost.
(2) Replace the conductor only with a capacitor conductor. The increase in capacity can be achieved without increasing the total weight of the conductor too much. It has the advantages of no tower replacement, low total investment, and a short construction period. With a capacity increase of 30-150%, it is usually possible to meet the capacity requirements of medium-term developments and is a very cost-effective option.
Overhead lines must be able to operate at a normal temperature of 100 to 150 degrees. In this regard, there are two technical ideas for improving the wire's resistance to high temperatures. One is the use of a flexible aluminum wire with a very strong core that can withstand high temperatures. The other is the use of heat-resistant aluminum alloy wire with the addition of rare earth elements such as zirconium and yttrium. With proper design and selection, capacity can be increased by simply changing the conductor.
In summary, aluminum, aluminum alloy core, or full aluminum alloy as the representative of energy-saving wire, and heat-resistant aluminum alloy, soft aluminum wire, and carbon fiber composite core type as the representative of the capacity of the new wire is an important development direction of the future.
2. Urban development and offshore wind power to promote the rapid development of the cable industry
Underground cables. Despite the excellent cost-effectiveness of overhead lines, new urban transmission and distribution lines are increasingly built using underground cables due to space, environmental protection, and operational safety constraints. In addition, existing urban overhead lines will increasingly be converted to underground cables. There is a clear trend toward burying urban power networks.
Submarine cables. Offshore wind power, which represents a significant portion of the future of new energy generation, is one of the fastest growing sectors of the future. Submarine cables benefit not only from the growth in installed capacity of offshore wind power but also from the growth in the distance of offshore wind power. In the context of the global energy revolution, submarine cables are expected to experience an exceptional period of development as the preferred solution for networking power between land and islands.
3. Very high capacity transmission: GIL corridors
GIL transmission systems consist primarily of a grounded aluminum alloy shell and integrated aluminum tubular conductors insulated with gases such as SF6.
GIL transmission technology is expected to be used more often in high-power applications. With the gradual increase in urban electrical loads, there are already situations in some medium and large cities or industrial parks where cables cannot meet the power requirements.
GIL lines have lower transmission losses, lower capacity effects, and higher capacity than cables, and their high transmission capacity (up to 3000 MVA in a single circuit at 550 kV) allows them to be directly connected to overhead lines in suburban areas.
Although the initial cost ratio of GIL is currently very high, it has a long service life. GIL systems, over 300 km in length, have been in service for over 35 years worldwide and no system failures have been reported to date.
For large capacity transmission systems that do not cover long distances, GIL is a more suitable technology than large cross-section cables that require air-, water- or parallel-cooled structures.
Summary Through analysis of overhead lines, underground cables, submarine cables, and GIL transmission systems, ZMS believes that the future direction of cable development will be high capacity, underground, and energy efficient. The evolution of technology has led to several new changes in the cable industry, which will result in numerous investment opportunities.

THE WORLD'S FIRST ELECTRIC ROLLER COASTER
Granville T. Woods (April 23, 1856 – January 30, 1910) introduced the “Figure Eight,” the world's first electric roller coaster, in 1892 at Coney Island Amusement Park in New York. Woods patented the invention in 1893, and in 1901, he sold it to General Electric.
Woods was an American inventor who held more than 50 patents in the United States. He was the first African American mechanical and electrical engineer after the Civil War. Self-taught, he concentrated most of his work on trains and streetcars.
In 1884, Woods received his first patent, for a steam boiler furnace, and in 1885, Woods patented an apparatus that was a combination of a telephone and a telegraph. The device, which he called "telegraphony", would allow a telegraph station to send voice and telegraph messages through Morse code over a single wire. He sold the rights to this device to the American Bell Telephone Company.
In 1887, he patented the Synchronous Multiplex Railway Telegraph, which allowed communications between train stations from moving trains by creating a magnetic field around a coiled wire under the train. Woods caught smallpox prior to patenting the technology, and Lucius Phelps patented it in 1884. In 1887, Woods used notes, sketches, and a working model of the invention to secure the patent. The invention was so successful that Woods began the Woods Electric Company in Cincinnati, Ohio, to market and sell his patents. However, the company quickly became devoted to invention creation until it was dissolved in 1893.
Woods often had difficulties in enjoying his success as other inventors made claims to his devices. Thomas Edison later filed a claim to the ownership of this patent, stating that he had first created a similar telegraph and that he was entitled to the patent for the device. Woods was twice successful in defending himself, proving that there were no other devices upon which he could have depended or relied upon to make his device. After Thomas Edison's second defeat, he decided to offer Granville Woods a position with the Edison Company, but Woods declined.
In 1888, Woods manufactured a system of overhead electric conducting lines for railroads modeled after the system pioneered by Charles van Depoele, a famed inventor who had by then installed his electric railway system in thirteen United States cities.
Following the Great Blizzard of 1888, New York City Mayor Hugh J. Grant declared that all wires, many of which powered the above-ground rail system, had to be removed and buried, emphasizing the need for an underground system. Woods's patent built upon previous third rail systems, which were used for light rails, and increased the power for use on underground trains. His system relied on wire brushes to make connections with metallic terminal heads without exposing wires by installing electrical contactor rails. Once the train car had passed over, the wires were no longer live, reducing the risk of injury. It was successfully tested in February 1892 in Coney Island on the Figure Eight Roller Coaster.
In 1896, Woods created a system for controlling electrical lights in theaters, known as the "safety dimmer", which was economical, safe, and efficient, saving 40% of electricity use.
Woods is also sometimes credited with the invention of the air brake for trains in 1904; however, George Westinghouse patented the air brake almost 40 years prior, making Woods's contribution an improvement to the invention.
Woods died of a cerebral hemorrhage at Harlem Hospital in New York City on January 30, 1910, having sold a number of his devices to such companies as Westinghouse, General Electric, and American Engineering. Until 1975, his resting place was an unmarked grave, but historian M.A. Harris helped raise funds, persuading several of the corporations that used Woods's inventions to donate money to purchase a headstone. It was erected at St. Michael's Cemetery in Elmhurst, Queens.
LEGACY
▪Baltimore City Community College established the Granville T. Woods scholarship in memory of the inventor.
▪In 2004, the New York City Transit Authority organized an exhibition on Woods that utilized bus and train depots and an issue of four million MetroCards commemorating the inventor's achievements in pioneering the third rail.
▪In 2006, Woods was inducted into the National Inventors Hall of Fame.
▪In April 2008, the corner of Stillwell and Mermaid Avenues in Coney Island was named Granville T. Woods Way.
