Solar Roof Tiles that Blend In with Non Solar Ones

Treehugger has this entry about a product that needs a close look at - roof tiles that blend in with your regular ones but which are actually solar photovoltaic tiles which would power your home: http://www.treehugger.com/files/2008/10/solar-save-buiilding-integrated-solar-photovoltaic-roof-tile-open-energy.php The design is lovely and I could see a huge market for them if they would sell their products, for example, in India, Sri Lanka etc. I guess the company will have its marketing department busy selling these in the USA itself - hope they do well enough to move abroad and aggressively! Check their website out at: http://www.openenergycorp.com/ Their other products like Solar Architectural Glass etc also look superb. Great work, guys!
