Zothecula writes: Swedish company, Soltech Energy, recently received the gold medal for this year’s hottest new material at the Nordbygg 2010 trade fair in Stockholm, Sweden. The award was fitting because it was for the company’s home heating system that features roof tiles made out of glass. The tiles, which are made from ordinary glass, weigh about the same as the clay roof tiles they replace but allow the sun to heat air that is then used to heat the house and cut energy bills.

you looked at it in the right way, did not become still more complicated.
