It's pretty cool so see a combination of manufacturing, installation, and operation. For a distributed power grid this might be a clever addition, add some solar, wind and perhaps battery-backed buffer and emergency fuel-powered generator and you might have yourself a pretty reliable self-sustained power source. I imagine out of those, the wind one might need the most maintenance, or if a lot of crap comes down, the solar panels need periodic cleaning. I wonder what maintenance this generator needs, besides the obvious stuff (brushes? lube on contact points? bearings?).
