Roofs for rich green people
Interesting idea, but what about hail?!
“When scientists at Dow Chemical looked at the possibility of manufacturing solar panels a few years ago, the company rejected it out of hand, says Chief Executive Andrew Liveris. Dow had no experience building solar panels. Yet their concept was alluring: integrate thin-film solar cells into roofing shingles. In place of traditional asphalt shingles, several hundred of these nailed onto the roof could generate enough electricity to power a home. Liveris sent them back to the lab, then decided to take the plunge.
Today those scientists are testing prototypes of the product, which Dow calls Powerhouse. Dow’s aim is to start selling Powerhouse next year. Because they look like traditional roofing material, the solar shingles are more likely to get the nod from uptight homeowners’ associations. Now, says Liveris, “I believe this will be solar for the masses.””
