Building a long gear train using 186 Lego gears. Many different types of Lego gears are used. Enjoy!

Inspired by Daniel de Bruin's "universe's biggest gear reduction":

The finished gear ratio:
or 1.0342e100:1
or 1.034 GOOGOL:1

Rotation time for the last gear:
52433879932503535381614991275498187972589101825233846406570841889117043121149897330595482546 years
or 5.2434e91 years

Formula for the gear ratio:
24/8 * 40/8 * 40/8 * 40/8 * 60/1 * 12/1 * 168/1 * (140 / 8 + 1) * 141 * 20/12 * (40/8)^20 * 20/12 * (24/1)^20 * 56/16 * (36/1)^10 * (40/1)^18 * 15/9 * 56/1

List of gears used:
27x Gear 8 Tooth [3647]
1x Gear Expert Builder 9 Tooth [g9]
6x Gear 12 Tooth Bevel [6589]
2x Gear 12 Tooth Double Bevel [32270]
1x Gear Expert Builder 15 Tooth [g15]
1x Gear 16 Tooth [94925]
2x Gear 20 Tooth Bevel [32198]
23x Gear 24 Tooth [3648]
10x Gear 36 Tooth Double Bevel [32498]
49x Gear 40 Tooth [3649]
2x Turntable Large Type 2 [48452cx1]
1x Turntable Large Type 3 [18939 / 18938]
8x Gear Rack 11 x 11 Curved [24121]
1x Gear, Hailfire Droid Wheel [x784]
1x Gear Worm Screw, Short [27938]
51x Gear Worm Screw, Long [4716]

For those wondering, the visual effect I used in the end montage is called Find Edges, comes with Adobe Premiere 14.

Pretty cool...BUT....given that these are plastic parts, I predict that the rapidly spinning gears will shred themselves and be long gone well before the end piece has a chance to rotate even once... ;-)

All this and it still requires batteries to run that will have to be changed long before some of these gears even turn.

Why am-I watching this at 3 am?!
Kevin Sanders MD
watching paint try is half a googl better than watching that last gear spin
best channel ever
Imagine one of the gears is slipping so the end gear will literally never move.
wait yea im wondering could you spin it from the other direction, what would happen please show

To put it in perspective... That contraption will degrade into iron before it ever spins once. And if for some reason it never does the universe would be reduced into nothing before it ever finishes. So there would be nobody around anymore to witness the holy lego relic complete its cycle.

nice. now run it in reverse.

Большой минус быстрый износ первых деталей в системе всего миханизма. Да и одной батарейки будет мало для полного цикла.

The motor would not be able to move the man at all because of efficiency losses, after a few minutes after a certain amount of gears biting the motor would give up: Every gear induces small efficiency losses due to friction.

How does the gear ratio 375 exactly amount to the 375 rpm? The gear ratio is based on the number of teeth? I'm not trying to say it's wrong I'm just confused

This would make a great sci fi movie, like there is a civilization somewhere in the cosmos with almost 0 modern technology like the mwdieval times that worships the mechanical god that is a huge machine that is working for thousands of years non stop and the prophecy says that once the statue makes a full rotation something big will happen and change the whole world but in reality the "government" knows of the gears and the machine and is something that they use to control the people religiously until the hero finds out somehow and saves his people from the low key tyranny.

make it so it doesent run out of bateries and doesent decay and the last gear wouldnt have mouved by an atom that our fucking universe vould have mostly died ...

it would be perfectly accurate if you just didn't hook up two gears.

Even if the first gear can spin at the constant speed of 100 quintillion rps (assuming there's something that can make it go THAT fast for an infinite period of time) then it would still take the last gear 3.2 sextillion eons (given that 1 eon = 1 billion years) to complete one single revolution. And for that long, trillions of universes/multiverses/dimensions could've been created and destroyed millions of times.
