I'm willing to overpay for one of these. I really believe that a lot of good can come from off-the-grid power, and I would invest to help that happen.
So much of our lives is about how this corporation or that government agency has us by the balls. So much of our politics is payback. How something like this could change the balance of power back toward the hands of the individual!
It's not just traditional energy companies that worry about something like that happening. There's a lot of entrenched power in the hands of a shrinking number of people because people can be squeezed. I think about it every time I have to fill the car with gas.
The other key would be open-source, off-the-grid networking. Think about how life and politics would change in the absence of Big Energy and Big Telecom. I'm sure someone else would try to step into the void left by these behemoths, but once you start down the road away from dependence, it gets easier to get rid of the next tyrant.
