force of buoyancy will be greater than force of gravity

it will stall

All energy wasted fitting balls through hole

See that flap at the bottom? It pushes down on the balls.

the chain around the sprocket and generator will also drag down the upward force of buoyancy

The upward force cause by the water is on the entire ball assembly not just the 1 side.

Ignoring all practical forces such as friction, this won't work purely because the buoyancy of the few balls inside the tank will be outweighed the by the slightly more balls not inside the tank. The balls would need an upward buoyancy of AT LEAST (no. of balls outside tank)/(no. of balls inside tank) to drive the system, which is physically impossible because it cannot have a buoyancy greater than its own weight.

weight*(no. of balls outside tank)/(no. of balls inside tank)

All ships have buoyancy greater than its own weight.
The balls can emulate the same effect be being fill by air

To all those saying it's the seals force, what about this?
This probably wouldn't be buildable because of the communicating vases thing, but what if it was, would it work?

>>3043438
probably too much friction on the hinge like things keeping it in place, but this could ba avoided in 3d

You cannot into water physics

>mfw when poster doesn't understand hydraulics

What about this one? I've always wondered about this one

A stick is not a rigid object. When you shake a stick, the stick bends, and it takes time for the motion to go along the stick.

>>3043467

have you tried moving a stick that's 1km long? let alone 1 ly?

Read the post idiots, it's a what if scenario. I know it ain't buildable.
Is it only the impossibility of it that makes it work?

please go away

Wow. This thread is full of the most asinine attempts at explanations of all time. It is supremely clear that none of the posters have the slightest idea about what they are talking about.

In the original design the downward work done on the ball by the column of water as the ball enters the chamber is necessarily greater than or equal to the work done by the buoyant force as the ball rises to the surface. Ergo no infinite motion machine.

The second design is obviously flawed in that the water level in the left and right chambers will even out because there is no pressure difference.

the ball that breaks the seal will have to push against the weight of water in the tank.

To the previous posters.

1. Force of gravity does not need to equal the force of buyoancy. Just because there's only force applied on one side of the system does not mean it will stall since it's cicular.

2. The opening's a problem, but the picture is obviously an approximation. Think sealed pockets of air mounted on a belt instead of balls on a chain and your problem has nearly solved itself. In any way it does nothing to disprove the theory.

3. See 2

4. Obviously the generator requires force in order to genereate electricity. The buoyancy is supposed to provide this force. Are you even making a point?

5. This is plain wrong. The upward force only works on the balls that are in the water. If the whole thing were a tube of air without compartments this would obviously not work, but the compartments/balls change things a bit.

6. The balls outside the tank hardly weigh anything, while their volume causes them to displace water that outweighs their contents (air) by a factor of ~833. Say a factor of 700 to account for the materials of the belt and compartments filled with air.
@OP, I say build it and see if it works.

>>Build infinite motion machine to see if it works

Wonder how this is going to work out...

Also this...

....you knew this was coming /sci/ lol. Why doesn't this work?

>>3043544

oops forgot to post image. Drunkfag

Replace water with, say, carbon dioxide and fill the bubbles with hydrogen - no need for water anymore!

What if they were balls of superfluid in a vat of oil (or anything else that couldn't mix with the superfluid)
