Scientists reveal nanowire that could be used to make jackets far more effective at keeping us warm and give them their own built in radiators

As temperatures drop across the country, scientists have revealed a smart nanowire that could revolutionise cold weather clothing.
They say it can both protect us from the elements better and generate hear more effectively.
It can also create fully breathable fabrics.

But Stanford scientists have now developed a novel nanowire coating for clothes that can both generate heat and trap the heat from our bodies better than regular clothes.
They report on their technology, which could help us reduce our reliance on conventional energy sources, is published in the ACS journal Nano Letters.
Yi Cui and colleagues note that nearly half of global energy consumption goes toward heating buildings and homes.
But this comfort comes with a considerable environmental cost – it's responsible for up to a third of the world's total greenhouse gas emissions.
Scientists and policymakers have tried to reduce the impact of indoor heating by improving insulation and construction materials to keep fuel-generated warmth inside.
Cui's team wanted to take a different approach and focus on people rather than spaces.
The researchers developed lightweight, breathable mesh materials that are flexible enough to coat normal clothes.
When compared to regular clothing material, the special nanowire cloth trapped body heat far more effectively.
The researchers developed lightweight, breathable mesh materials that are flexible enough to coat normal clothes.
Because the coatings are made out of conductive materials, they can also be actively warmed with an electricity source to further crank up the heat.
The researchers calculated that their thermal textiles could save about 1,000 kilowatt hours per person every year — that's about how much electricity an average U.S. home consumes in one month.
Put the internet to work for you.
