Green power for more people
I'm not that into it yet (crap has to be cheap to compete with burning dead dinosaurs), but there's a Kickstarter that marries solar and wind in a relatively affordable device. There's been enough talk on here of batteries, inverters, solar, geothermal, and wind that I thought someone might find it useful.
What do you think? List price is $7000 right now with an inverter. The charts in the Kickstarter assume you'll be taking advantage of government subsidies in the US, so you might just want to use the list price in your calculations.
