I ordered one of these gadgets for my grandboy. I'm gonna sick him in search of locomotion with some of his leggo stuff. It's a steam powered generator that produces 5 watts. Maybe screw that watts stuff and see if that flywheel will turn an axle?!?!!?
From what I read, you fill the little wicked bottle with alcohol and the tank with water, light it, wait for a heat up and spin the flywheel and the steam takes over...gonna check it out.
