    So even if the 12th gear started moving at the beginning of the known universe ~14 billion years ago, it is still likely not going to finish 1 full rotation by the end of it.

    That's pretty crazy gearing, the damn thing will take ages to even take up all the slack in the gear set.
    Maybe they could have built it with some strong components and only geared it down to a point where you would see something after one month for example, and then powered it with a ridiculously small driver to show people the effect of torque multiplication through the gear set when the final gear breaks out of the concrete block or starts turning it and breaking whatever it's mounted to if the machine doesn't just turn first.
    Either way you get my drift.

    The question is whether it'll corrode or wear out faster than it can take up the slack in the gears. Realistically, by the time there's no slack at the last set of gears, the motor driving it will have worn out and been replaced millions of times.

    Yeah... I'm normally a fan of these things, but in this case... what is the point?

    To prove gears work?
    To prove concrete is a liquid?

    Meh.

    Damn, if only it didn't have those worm drives, we could hook this thing up in reverse.

    Why is this being touted as some sort of awesome or amazing thing...?
    So freakin' what?
    Gee I could add ANOTHER gear, and get an even SLOWER rotation..gosh golly!

    All the comments on saying "who cares" and "waste of time"

    well, you must for commenting and better not see anyone playing games, watching TV, on forums!!! etc

    Its cool, It could be used to educate people on gears.

    So if you kept sticking gears on, could you basically move anything that was at the end? What about a building? Or the world? Or the entire universe?....

    The torque and shear stresses wouldn't allow it. Even in this case you'd brake a gear tooth or axle before the concrete moved.

    You can backdrive worm gears if the gear geometry and friction allows it. I find this guys other sculpture to be much more intetesting, and I'd hardly call this mind bending.

    Why is this so incredible? I built something similar out of Lego when I was a kid, and I'm sure plenty of people have.

    I'm reminded of a clock in Shakespeare's House in Stratford-upon-Avon that measures centuries.

    Best quote from the comments section (despite some wrongness in the body of it):

    Welcome to the internet. Pls point us to something more awesome :p

    Interesting question :- what's the likely torque at the output shaft assuming no slack in the gears?

    It has been around for a while, the video was put up in 2008, and whilst it is not that amazing I do like it as a practical example of gear ratios.
