Just to nitpick on a great idea of Don, let me add that the item on CO2 
emissions is heavily dependent on the structure of local power sources. 
What Don says might be true of coal-based electricity; but down here 
100% of our energy comes from dams since 1973 onwards. We had a energy 
shortage on 1979 and we had to pay what the local National 
Administration for Electricity labeled "thermal overprice". Thankfully, 
it lasted little.

However, Don's ideas (both the project and the howto) are excellent.
