I sent him an e-mail with a few questions. His mechanics are sound, but his design is not robust enough to actually be put into practice. Here are some questions I raised:
1. How do you determine the direction your machine will spin? The machine is theoretically symmetrical and doesn't have a specific direction for the barbell to fall.
You compare it to setting a bicycle upright which could fall in any direction. However, I see how you could balance this once its spinning by allowing its momentum to carry it past vertical. But for low RPM builds... is the designed doomed?
2. How do you keep pressure in a machine that is always spinning? If I wanted to use water as the fluid, what sort of 'piping' or apparatus would you use to pressurize each side as the machine switches positions? I think the use of water head that you suggest is MUCH more involved in your system than you make it out. Can you clarify how you imagine that system to work?
3. How do you switch the pressure differential fast enough to keep the machine spinning using solar?
4. Most importantly! Have you built a working model producing the power output you claim? If so, is there a video of it in action?
So yeah, while the energy transformation part of the machine is valid, there are no details on how you would deliver the energy to the closed vessel in terms of water pressure head, pressurized air.
He suggests using solar in a closed-scheme (I assume), but there is no details on how to provide the power to the alternating machine at a rate that would keep that machine spinning.
He also grossly oversimplifies the efficiency of the setup by ignoring the efficiencies of the energy delivery setup.
I'm interested though. Large scale, low pressure machines are usually simpler that smaller, large pressure machines.
