For a while now I have been researching the idea of putting some solar panels on my house to generate power for hot water or heating a room or two. I have had solar exterior lights for a couple of years and even tried a solar powered water fountain in my back yard last year (but the angle of the sun in my patio is poor, so it only worked a couple of hours each day).
I ran across this blog post from Google the other day about President Carter's solar panels he had installed on the White House, that Ronald Reagan later removed. The panels were found in the GSA warehouse by a college in Maine and put to good use. Now one of the panels is located in Google's Reston, VA office and the rest are powering the college's hot water for their cafeteria.
Now, lets see if Obama can get some of these re-installed pronto!
