Gravity/Buoyancy Device Simple Schematic. (Tell me why it won't work)

[tytus]

If you force the ball to pass through paddle wheel type power generation devices on its way up and down the system, the energy could be stored and used to aid in its reinsertion at the bottom of the water tube.
The magnet at the top gives it a little help coming over the edge even though it is already inclined to go over because of its direction of travel caused by the slant at the top of the water container.

Tell me at which point does this device fail ?

if your ball float they will not able to pass the paddlewheel, so your idea don't work

[tytus]

Ok, so what if we changed the reinsertion mechanism to have the ball roll to a spot directly under the water tube and then have a plunger push it up through a one way valve/gate ?), then if we make the device 20 feet tall and thin (thereby increasing the energy produced and reducing the water pressure at the bottom of the watertube), the ball would generate a lot of electricity if it floated up and then fell through the air by that distance through a bunch of paddlewheels attached to generators which would store the energy in a capacitor for use in powering a reinsertion mechanism. Surely this amount of energy would be enough to operate a simple reinsertion mechanism at the bottom of the device.

Lots of energy required to prevent water from leaking when inserting the ball.
Explain how you'll insert the ball in detail, and you'll answer your own question.

Inserting the ball at the bottom of the column of water requires displacing the water upward.  This is all the energy the ball can recover when it is displaced by the water.  If the process were 100% efficient the net energy becomes zero.
