> What about no power?

Solar panels? You can go down to Harbor Freight right now and pick up a setup that will run a laptop or tablet for a while, for a couple of hundred dollars. One wouldn't have to spend a ton more to get a setup that can run a decent PC with a GPU for at least a little while.

I mean, you're probably not going to run it all day, especially not in the part of year with fewer daylight hours, but anything's better than nothing. Plus the same solar setup can be used to power other useful things.
