thats awesome, i'm glad more and more research($) is going into this type of alternative energy sources.
and guys, don't rag on the price tag, you have any idea how much a computer in the 80's was? i remember my parents were debating wether to get a new car or to get a computer. granted the car was used and only 2500 dollars, but the computer was nearly 3K including all of the peripherals.
