What would go wrong here?

The seal doesn't work.

This.
Plus losses due to friction.
Remember the laws of thermodynamics:
1. You can't win.
2. You can only break even on a very cold day.
3. It never gets that cold.

It's unlikely the chain would have enough momentum to "restart" itself, or get over the air gap above the water, even once.

>>11417117
I can imagine a seal/air vessel combo worked? There must be some reason it wouldn't work in principle.
>>11417123
>enough momentum
The force would be continuous. It's a circular chain with air-balls

when a ball goes into the water it has to do work to displace it, negating all the benefit from the buoyancy

[Anonymous No.11417154]

>>11417132
Fair enough. It fails for other reasons.

[Anonymous No.11417159]

>>11417152
not enough to negate the buoyancy of multiple balls, presumably

[Anonymous No.11417160]

>>11417152

That's right. Pushing the ball through the seal would require lifting the water up and out of the way of the ball. This would consume more energy than the floating balls could provide.

>>11417159
each one of those multiple balls has to displace its own water

[Anonymous No.11417221]

>>11417209
For each ball that has to displace water one at a time, there are multiple balls simultaneously pulling it up.

[Anonymous No.11417426]

Easy.
>Seal has weight of all water above it pressing down
>Lifting force on each ball is far less than the pressure from the water, as all balls need to fit through the seal

>>11417221
it doesn't matter, each ball generates x amount of energy going through the water, and uses y amount of energy displacing it, for multiple balls you just sum those numbers

[Anonymous No.11417717]

>>11417115
The force to pull a ball through the seal even if it is perfect is a function of the density of the fluid and the volume of the entire column of water above the ping pong ball. The buoyant force is a function of the density of the fluid and the volume of each ping pong ball. You will never get those values to be equal.

[Anonymous No.11417783]

>>11417681
You sum what numbers? y? because you wouldn't. If there are 5 balls submerged at any time 1 ball has to use energy to displace water, then well that's the buoyancy of 5 balls at all times vs the displacement of 1 ball at all times. The fuck you mean you sum them?

[Anonymous No.11417785]

>>11417160
but what if you had an anus instead of a seal that could conform to the shape of the ball for very little energy? Kind of like an automatic door?

[Anonymous No.11417793]

>>11417717
not true if the system was redesigned to have cylinders longer than the column instead of balls.
if the cylinders is taller than the water column then the pressure at the seal will be displaced

[Anonymous No.11417797]

>>11417793
Congratulations you just plugged the hole with a stick and now there is no buoyant force.

The static weight of the water pressing down on the seal and ball chain would be greater than the buoyancy of the ball chain.
