A Gear Set Like No Other,

it is a gear system that represents a number, 

 the digit 1 with 100 zeros behind it, normally known as the number googol,

every time the first wheel completes 1,000 rotations, which happens in about an hour, the second gear turns 100 notches and the third 10, each following wheel is reduced by 10, meaning in order to turn the last and 100th one, the system would need a googol of energy, which the Netherlands-based designer says is “a number that’s bigger than the atoms in the known universe.” 

it is the brainchild of Daniel de Bruin who created it to celebrate spending one billion seconds on Earth,

this is a slightly longer view, taking 1 hour to watch, to watch his life time he would only see the first 10 gears moving, the video feed is here, now here is a thing, how many great, great, great grandchildren would he have to have, to see the last wheel not just move, but complete one entire revolution? answers with proof on a very, very long postcard please!
