New roofing material absorbs heat from homes and buildings

With global temperatures on the rise, no one is giving up their AC. More people are installing air conditioners than ever before, especially in developing countries where the middle class can finally afford them.

But AC has drawbacks: it's expensive, and it takes a ton of electricity, which usually comes from fossil fuels, causing air pollution and global warming.

A scientist has invented a material that reflects the sun's rays off rooftops, and even absorbs heat from homes and buildings and radiates it away. And — get this — it is made from recyclable paper.
In addition to the cooling benefits, the paper doesn't require any electricity, and it is 100% recyclable.

The paper can reduce a room's temperature by up to 10 degrees Fahrenheit, making it a radical but effective alternative to today's air conditioners, which consume a lot of power.

The technique isn't any more advanced than 4th-grade science fair project. Except instead of pressing flower petals into the pulp, you mixed it with the material that makes up Teflon. The "porous microstructure of the natural fibres" inside the cooling paper absorbs heat and transfers it away from the house.

Cooling paper are recyclable you can remake a new sheet and found that it didn't lose any cooling power in the process.
