Hair Gel Roof Tiles could help combat global warming

ow-tech roof tiles made from hair gel could provide one revolutionary solution to climate change. Scientists at the Massachusetts Institute of Technology (MIT) found that hair gel when mixed with water, changes colour depending on the temperature. The team of students used the technology to create special panels that reflected the suns rays away from Earth when it was hot but absorbed them in chilly weather. The carbon-busting roof slates work by mixing the polymer with water and sealing the substance within two flexible plastic layers against a dark background. When it is cold the polymer remains dissolved and the black backing shows through. This absorbs the available warmth from the sun, which could be harnessed to heat buildings below.
