"How can we cool houses without using A/C? Scientists have now discovered that one way would be to turn the roof and walls into a beetle’s shell.
That’s because tiny nanostructures on the beetle’s exoskeleton made of cellulose capture light and send it bouncing around whilst separating it into different wavelengths. This is why they appear to shimmer in greens and purples.
More importantly however, when the same nanostructures are pasted to the outside of a house, they can keep it 7.2°F cooler during the day and 20°F cooler during the night.
Some scientists are worried that too much energy will be used for air-conditioning in a climate that is warmed by 1.5°C, and so are devoting their time to coming up with energy-less ways to cooling homes.
GNN has already reported on ultra-white paint that can keep things cooler, and now scientists at the University of Cambridge are turning to cellulose nanomaterials inspired by nature that would create iridescent houses that are self-cooling.
“The usual way to generate a color is dye, but dye will absorb light and heat up, and that counteracts the cooling effect,” Qingchen Shen, a postdoctoral researcher at Cambridge told Fast Company.
As Shen explains though, color generally absorbs heat, rather than reflects it, but their invention of a thin nanostructure film made of cellulose under a thin film of white was able to generate over 120 watts of cooling power, as much as some air conditioners.
“We wanted to make it cheap,” Shen added. “That’s why we used cellulose-based materials. Cellulose nanocrystals can be extracted from wood or cotton. Cellulose is the most abundant polymer in nature.”
When pasted over walls or rooftops, the material could meaningfully assist in cooling the interior of the house and reduce electricity usage by a fair amount.
The colors could make a house look pretty psychedelic in the sunshine though, so the team is probably better off leaving the marketing for the major coastal cities."

Tw death
The queen is dying surrounded by family.
My gran died surrounded by family this May.
The queen has a completely heated, warm mansion.
My gran died in always cold house because she couldn't afford the heating on her pension.
The queen dies with millions in assets, diamonds, jewels, land and property.
My gran refused to tell us she was in trouble because she didn't want us to get into thousands of pounds in debt.
The royal family arrives in private jet and into land rovers.
I couldn't afford to fill my car with petrol.
The queen dies surrounded by medical professionals, her own private medical team and ambulance on standby.
The ambulance never showed for my gran. She was high priority, a presumed stroke, and after 2 hours a small medical car arrived to try and resuscitate her but it was too late.
Prince William wont have to preform CPR on his gran while a 999 operator shouts down the phone at you, but I had to.
Nothing about this horrible country is equal.

European governments are trying to reduce energy use. Great. But instead of telling people not to heat their homes this winter, they should scale down unnecessary corporate production (luxury goods, advertising, planned obsolescence, etc) and cut the purchasing power of the rich.

Russia sabotaged a gas pipeline in the ocean. Methane is 25x more potent as a greenhouse gas than CO2. Remember to recycle your plastics and turn off your AC to offset your carbon footprint this month. /s 🙃

I tend not to let work leak into my personal life too much. But I know a lot of people are suffering with heating and keeping warm and costs and such. And I do work giving money guidance...so the knowledge helps in some cases.
I do want to direct to Money Saving Expert and their tips on heating the human not the home. It may help some of you who could be struggling. Being cold is rotten.https://www.moneysavingexpert.com/.../heat-the-human-not.../
Stay warm friends <3

sugar can be used as an emergency gasoline substitute if you find your self out of gas far away from a gas station, due to its high energy density. It can be poured directly into the gas tank. 4 cups ≈ 1 gallon of gas

Nilsson didn't have enough firewood to last all winter. He had thought that a warm house was a basic human right and that the government would make sure everyone had affordable electricity for heating during the winter. How naive he had been 🥶

To my fellow brethren in the UK facing a difficult winter this year on top of a medical system shattering under the weight of incompetent political interference just remember: the possessions of Tories make for excellent kindling, and in a pinch so do their clothes. Whether they’re wearing them or not at the time is of no consequence.
I know we like to rally behind the slogan “eat the rich” but just remember, these vermin are poisonous and of no value, nutritional or otherwise.
