So while surfing the web I come across this website: http://www.solar.philips.com/en/wtb/index.htm I am not very knowledgeable about electric power. I am wondering if anyone knows much about this. How much power does it create? How much power does the typical home use? Will it be available in the US? Is there another system available from a competitor? What are the costs? Is it efficient/cost effective? And most important - will it be compatible with my HT system?
