Weird space heater! It would be cool to put another high efficiency
motor on the other end and spin that side the opposite direction, spin
them both real fast until they starting glowing at each end. Wrap a
thermostat loop around it and use it to heat your living room. Probably
would need some kind of active lubrication system to keep it from seizing up

Er, it won\'t turn from that end, what I mean is rather have two
reductions starting from each end that meet in the middle

 Well if you could turn the other end at 100 rpms, then you could spin
the free end at 100 googol rpms!
Faster than the speed of light
oh lets see 4 inch gear 12 inch

used 10,000 hand-made nails to define it\'s gear ratios. It only goes out to Neptune so your have to wait 29 years for a full rotation. Uranus was discovered at about the same time that Eise Eisnga finished his planetarium, so it\'s not included in the model. He\'d have had to wait even longer for Lego..
