I had to laugh at this clip of a Japanese hand-cranked vending machine. It's supposed to be deployed in areas where power supplies have been disrupted. By cranking the handle 70-odd times, you apparently generate enough electricity to work the machine. See for yourself.
I don't know whether you also generate enough electricity to cool the beverages inside . . . but you'll certainly want more than one of them, after working up a sweat cranking that handle! Great marketing idea, no?
