The weekend is warming up: Some DIY solar projects
Jun 26 2009 10:26AM | Permalink |Comments (0) |
No big plans for the weekend? How about some DIY solar energy project plans? BuildItSolar has a plethora of plans. Some that look especially good:
-Solar-charged EV scooter (“Don rides the scooter 5 miles to work each day, and can fold the panels out for charging the battery while parked at work.”)
--Solar pool and hot tub heating
-I especially liked the section on water efficiency, including rainwater harvesting and graywater use. (Its only relation to solar is the water still.)
-$1,000 solar water heater (“Bottom line is that the system will offer a family of 3 a payback period ranging from 2.5 years to 3.4 years depending on the fuel. The system will also reduce CO2 emissions ranging from 2000 to 4000 lbs of CO2.” It’s installed in Montana.)
