Imagine you have a buoyancy wheel with several spokes - let's say 10 spokes. On each of the spokes ends there is a hollow container that is filled with clean water. Each container have an opening at the outer end. This whole wheel is now always under clean water.
Now! We apply a DC current through the clean water inside those containers at the bottom, and those on one side of the wheel, and let the DC current flow until the containers is almost on the top.
Well! What will happen? The containers at the bottom, and all of those which is on one side of the wheel, will be filled with HHO, and therefor water will be displaced. HHO is a gas that is even lighter than air. Now, one side of the wheel is lighter than the other side, because one side is filled with HHO, and the other side is filled with water. This will force the wheel to rotate - no doubt about that.
Each time a container almost reach the top, the gas will escape from the opening, and water will pour back into the containers. We save the gas and ignite it to boost the wheel so we will get back most of the energy we spent to make the electrolysis of water.
Also the HHO gas displace 800 times the the volume of the same weight in water. 1 liter of water gives 800 liters of HHO. 800 liters of displaced water has a potential to provide a great torque on a wheel!
What we know, is that there is a connection between how much gas we produced (The potential energy we store in HHO) and how much energy we applied to the water to make HHO. But is there a connection between the mass of the water (its potential energy in the mass of water) and the energy applied in the electrolysis to convert water into HHO?
I mean, if we anyway gets back most of the energy (Even only 50% back) in the electrolysis process by igniting the HHO produced, there should be literally loads of excess potential energy that we can harness in the buoyancy wheel!
What do you think guys? Need drawings?
I will also post this under half baked ideas.

I like the idea. I guess it will depend how much HHO you can produce, and how to refill the containers to repeat the process and what speed you may be able to do. If to slow you will still need an outside source. Maybe from solar power. At least it would be cheaper to produce the HHO.

Solar powered HHO would work fine. However, I had in mind to make this self running. The gas could be used in a fuel cell to make electricity for an electric motor - in order to assist the wheel by giving back the energy that we took to make the gas. We could have a central gas generator which is pumping gas in the containers via valves and tubes. The spokes can be tubes too to fill the containers. A big diameter wheel would provide enough torque, but a gear is increasing rpm on a generator which is used for the electrolysis.
At least in theory this wheel would be a selfrunner. I cannot understand why it shouldn't be:)

First we have to look at how fast it makes the HHO. Will it be fast enough to turn the wheel and will the fuel be enough to run the process if not. Like I said before. I like the idea. Research is needed and then if deemed plausible it needs to be built and tested.

I agree. I will make some brief tests on the wheel without feedback first. On youtube some claims 200 liters pr. minute.
I need to build a better HHO generator. My generator is too small, or at least require higher voltage to increase the production.
I have other ideas that might be better, but still using electricity to displace water. I'll do some tests first.

If anyone can assist with alternative ways to make a device that works under similar or alternative conditions, please feel free to add comments in this thread :)
I have however done some research on fuel cells. The efficiency is normally 40 - 50%. So when using this to power an electric motor (With 70 - 80 % efficiency) to assist the buoyancy wheel, will probably not be the way to go. In theory it is beyond doubts that this would be an OU device, but I think the efficiency of the whole system in practice will be very low, so most of the energy will probably be lost as heat or other forms of resistance instead of being sustained inside the system as kinetic energy. I will do some more research and also try to figure out a model that works under other conditions - not in water, but maybe air. This will take a while so don't hold your breath.

This idea was on mythbusters. They said it moved "too slow". Really no idea of what they are talking about. It's not designed to move fast, it takes a little bit of time for the transfer to happen AND any movement at all can be converted. They used propane and propane tanks linked with a pipe.

The experiment on Mythbusters was based on high pressure tanks. Liquid propane under high pressure does not distribute easily due to small temperature changes. I did see that episode, and the tanks did almost not move at all. That said, experiments done by these people is not always the true story.

- the 'hatched-jobs' they did on both acetone & Bedini's motor being prime examples! I never watched another episode after seeing the Bedini one...
I have been building something similar over the last month, But it is not floating in water and it's self powered, keep thinking along those lines your close!
