Cadman’s Hydrostatic Displacement Engine

[lumen]

Hi Brad,
No, I think all the hydraulic math is good and works but the displacer weight (buoyancy problem) was never correctly accounted for.
Like a 3000 ton ship will displace 3000 tons of water to stay afloat. The problem is worked in reverse to find the required weight for the displacer to sink.
What is the weight of the water your displacing......so the displacer must weight that much or more to sink, or it will float.

You are both right. It finally came to me, how to say what makes the difference for the displacer, why the water will move upwards.

Pressure differential.

Both the piston and water column exert force and create the pressure. Less pressure above the piston means the lighter body, the water column through the displacer, will be forced up by the pressure below the displacer piston. This not the same situation as the water feeding the pressure piston.

I'd like all readers to think about this word, I don't think its been mentioned as yet.

That is great! I guess that puts that issue to rest. 

Thank you sir!
