Re: Profitable Solar Power - A suggestion



Larry, I see from your link that you live in So Oregon. As a child I spend
my summers in the Trinity-Shasta National Forest in Calif. Most of the
people I knew there lived off the grid, and many used water for their
electricity. Not a passive way to harvest electricity. Older technology.
Can you do this at your place?
