I have a customer who has a sweet solar powered fountain aereator system. But he is kind of deep pocketed and can afford anything. He got a beta model, and the price has come down. I had a brochure somewhere, lost in my pile of things I have to get caught up. But it is pretty much one unit, all inclusive. The spray from the fountain keeps the solar panels cooled for maximum efficiency. I have a few photos of it but am photo posting challenged. Should breakdown and get photobucket or something. Just another thing to do on the long list of Frog's would like to get done list. Have 4 straight 12's coming up though. Outlook is bleak for anything to get crossed off that list. But as far as feedback, customer loves it.
