It's pretty simple: for each pair of gears that mesh with each other, one has ten times as many teeth as the other, which gives a ten to one reduction. If you chain 100 such reductions, you get 10^100 to one reduction.

But the construction of it ??! It's one thing to put the numbers down, we know they round out nicely, but in my head this needs a very minute level of construct engineering.. For example: If 1 gear(cog?) is 1/1000 of a cm out, would that not effect the ratio over this 'distance' ? Edit: I might just sound like an idiot right now, but when we get down (or up) to these numbers, i can't help but feel manufacturing numbers play a bigger role

  As in the video, they just reuse the same ratio gears in cascade?

    You're right, took me a bit to catch up.

  It's a gimmick. Over 90% of the system doesn't do anything because mechanical imperfections overwhelm the theoretical gear behavior.
