MP: I remembered that they ordered something, but couldn't remember if they actually ate it.
Electricity: Static probably wouldn't help too much. You can only discharge it all at once. Too little, and you get nothing. Too much, and you could burn it out. Even if you get the right charge, you couldn't keep it up for any length of time.
Better option would be to build a crude generator using a couple of magnets, some wire, and a hand crank.
A quick google search brings up
these plans , which are about as simple as they come. And there's a bit more info on
this page .
Basically, though, you get two magnets, as strong as you can find (the stronger the magnet, the higher the voltage). Face them towards each other (north pole to south pole). You'll need something to hold them in place, since they will attract each other.
Rotate the wire within the magnetic field between the magnets (or rotate the magnets around the wire), and you'll generate a current by magnetic induction. It'll be an AC current, but that's what most appliances are designed to use.
