Spray-on film turns any window into a solar panel

One big problem with solar power, is finding a place to put all of those big solar panels. People living in apartments can't exactly stick a solar array on the roof, so solar windows are the ideal solution.













We've seen other solar windows
before, but they tend to require replacing the entire window. This
solution from a Norwegian company called EnSol can be sprayed onto the
glass, resulting in a slight tinting. A thicker layer can also be used
on the walls for further coverage, then I suppose you could add some solar ivy if you really want the full effect.

EnSol has been developing the spray with help from the University of
Leicester's Department of Physics and Astronomy, and hopes to have a
product on the market by 2016.

How efficient is it though? Worth the cost? Im sure a spray on solar panel will probably cost quite abit. And I doubt you will be able to just spray it on yourself.

I doubt that it's efficient at all, well, the normal photovoltaics aren't efficient in general, so I wouldn't be surprised.

Well people love to buy "Green".

Yeah, of course. :\
