This is the dumbest thing ever. If you live in a city or a suburb, you don't need one of these things because you'll be connected to a grid that can give you electricity that is far more efficiently generated. If you live in a rural area with a lot of sun, then you can just put solar panels on the ground where they're not a bitch to clean.

I'm not against using solar electricity because it can be made affordable but this idea is equivalent to the backyard blast furnaces in Maoist China. It's a waste of time and only useful for status signaling to your eco-chic friends.
