Title: Bouyancy/Gravity Lift Pump
Post by: WildBill on November 20, 2009, 03:00:31 PM
Here is an idea I've been thinking about. Instead of trying to pump air into a float at the bottom of the tank (D), why not use a solid float(E) with a fixed displacement to create constant lift. With the transfer tank (B)empty, the movable assembly will float up and the attached cylinder(C) will lift a small column of water into the upper tank (A)(against Atmosphere) until it reaches the end of the stroke. The amount of liquid in the cylinder must be roughly twice the volume displaced by the float. Once at the top of stroke, upper tank valve opens, making the transfer tank twice as heavy in the down stroke, overcoming the buoyancy and pressurizing the cylinder in the opposite direction, making it effectively pump in both directions.  Thoughts? Facts? Fatal Flaws?     Thanks, Bill........

Same principale as this?

Why not just use a gas to lift the water and the lifting water to generate the gas. This would allow a bunch of free gas to operate a generator to do real work.

Still mainly concept, but appears the limiting factor would be the necessary depth to achieve self sustaining operation.

Well, the idea is similar, but the water pressure supplied by the tank, (F) is what keeps the static weight at a minimum. You shouldn't need more than say, 18 -20 lbs of lift to get it in motion....I think? :-\

The biggest problem with fluid designs is it takes time to move the fluid. So even if a one of these would work? It would not supply much work. But it would still set science in a quagmire.  IMHO
