I got a chance to visit a friend here in central PA who is setting up his property to be self sufficient on both energy and water needs.
A quick photo log follows of some of the efforts at two locations.
Caption is above image.
Solar photovoltaic system (rooftop) and a solar thermal water heating system on the side of the barn wall.
Direct solar thermal water heater (in detail)
Micro hydro potential.
He also has electric cars and batteries hooked up to the PV system. Further, he has a van with solar panels installed in top for road auxiliary power as well as power for lights, electric stove etc when they park/camp.
He also has 2 diesel cars that run on used vegetable oil! That's waste oil being used as a fuel! The house heating is supplemented by local wood furnaces. A lot of dead trees can be used as firewood (at least in PA), he also used wood pellets, that burn cleaner and completely.
All in all it was a great visit!
