Title: Buoyancy canister???
Post by: Frii on January 26, 2008, 09:31:24 AM
   Could a canister that is designed to collapse under the weight of water make energy? It would work like a submarine having air to float back to the surface and take on water to sink. I not sure how to make it expand at the top, maybe a lever that uses the weight of the canister to activate the lever. I not sure how to design it to collapse in the most efficient way. Could I make it into a wheel?

How do you intend to replace the air after it has sunk so it can rise to the surface again without expending energy?

It's going to work like a submarine it will keep air in tank that will not collapse. Someone else told me that a lever at the top would take more energy then is created at the bottom. So What if I use Springs on the inside that push out at a 100 pound and have a locking device that wouldn't let it collapse until the water weight is 600 pounds around it.

After your tank floats to the top you will have to let the air out or re-compress it so it can sink again.

This requires energy to re-compress or an air intake on the bottom. How will you do that?

Thanks, I didn't think of that part of it to re-compress the air. Is there a way to use the water weight to force the water out of the ballast tank that wouldn't leak? I think when its at the bottom the force of the water could crush a collapsable tank that would move levers to force water out of the ballast tank. When the water force is less it would let in water into the ballast tanks. It would also need a device that wouldn't let the collapsable tank collapse until it reached its depth would need springs to force it open at the right time when the water force is less at the top. It would also have to use levers or pulleys to counteract the weight of the water on the ballast tank flaps.

There?s even a better one.
Electrolysis in the canister at say 100 foot depth.
Fuel when it reaches the surface and energy from the buoyancy.
But it?s not at all OU.
It takes the same amount of energy MORE to electrolysis the water
At 100 feet (electrolysis under pressure) as you can recover from the buoyancy.
(say, a string running a generator as it floats to the surface).

Here?s my rethink of the Buoyancy Canister. It uses a piston in a cylinder. The piston doesn?t move instead the housing with the cylinder attached to the housing moves. So when the housing is collapsed there is air in the cylinder the piston would be to the outside or top of the cylinder. When the housing is open its full of water the piston would be too inside or bottom of the cylinder. The cylinder act as a ballast tank allowing it to move up or down under water. I?m thinking I could use several cylinders to make a bigger device, also, having cylinders on both sides. The air would be re-circulated by the movement of the housing that could be from an external source like an air tank in the middle of a wheel. It would have springs on guide pins that move the housing apart when the water weight is less then the force of the spring. It needs a locking device that will not let the housing collapse until it reaches the bottom or its crush depth.

You would be well advised to study hydraulics before designing machines that rely on it.

Thanks, I'll look into hydraulics.

This can't be made into a wheel it would be to big. At 200ft the water pressure is at 101.4015psi and it would have to sink to 1000ft to get to 448.2237psi. Other then that I do not know how to get power from it with the little force that would be made by one canister.

 :o  @ Brian,

Is this one of your tanks?

It might be best if you studied how a submarine works as well. They take on ballast (water) to sink, then expell that ballast to rise again. Your just trying to create a gravity wheel in a high friction environment. It might be better to use the theory of a hot air balloon to move your wheel.LOL
