DIY renewable energy projects
So you want some do-it-yourself climate solutions. Popular Science is the place to go.
The magazine details how, for $300, you can build a vertical wind turbine (pictured below) for your home in about three days. It will generate 50 kilowatt-hours per month, which might be about 10 percent of your electricity use, depending on the size of your house and how efficient you are. You can also download plans at windstuffnow.
Or maybe you want something a tad bit easier to make, something to “keep your gadgets powered even when the grid fails you.” Follow these instructions, and for a mere three hours in work and $150 in parts, you’ll have your very own solar charger (pictured below).
