    You're going to be waiting a while for a full rotation:

    This isn't legos, but it is a Googol to 1 ratio!

    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
    diameter spinning at, oh never mind.

    https://en.wikipedia.org/wiki/Eise_Eisinga_Planetarium

    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.
