Installing solar panels on the roof of buildings has become very
en vogue recently. But in a few years charging up your home
might be cheaper and easier than ever. The Norwegian company
EnSol AS has developed a thin, transparent solar film that can
be sprayed onto windows and other surfaces, rendering them able
to absorb the sun’s energy just as efficiently as solar panels.
The special coating consists of metal nanoparticles suspended in
a clear chemical compound, and could potentially be added to new
building materials during their manufacturing process, or even
to the roofs of electric cars. The company hopes to have this
miraculous spray commercially available by 2016.
