My guess is that this will never work. Any time I see the phrase "near perpetual motion" in a write-up I have to put on my skeptic's hat.
It seems that this inventor is going to obtain energy by changing the buoyancy of some type of actuator in a tall column of water: decrease the buoyancy, the device sinks; increase the buoyancy, it rises; and the resulting reciprocating motion is converted to energy. The problem he will most likely face is that it takes more energy to decrease the buoyancy of the device (to expel the water or increase the air or whatever other technique he is using) than he obtains from the system.

What kind of power? Electrical?
You can always use the potential energy of a solid object to lift something else and therefore do work on it. Tie a rope around the water tank and push it over.
If you want to use bouyancy to do work, again, tie a rope around a ballon and the other end of the rope to a rock on the bottom of the tank. When the balloon is released, it does the work of lifting the rock.

I guess this is just one of those wait and see. I would hope that a new source of energy could be found. I recently saw someone buring salt water that was hit by some em waves. They did not address the amt of energy required to produce the em waves just show that they could convert salt water with em waves to 02 and H2, and that of course will burn just fine. Again, we will just have to wait and see if either one of these become a new source of energy. It would sure be nice just fill your tank with salt water and drive away.

Energy in = Energy out ALWAYS
