Buoyancy motor with fire

Can you provide a link to the info.

Most buoyancy motors use water and a air pump and deliver like 1/3 extra power or they claim .

I saw a video on this where it was advised use a small air pump to bubble air to the bottom of a tank, and collect the air in a cup like chamber to create a buoyancy motor.

I worked out the math.  Calculate Volume of air / depth to maximum possible joule output.  So I knew exactly how much power it can max out at.  Then calculate how much power it will take to run a pump to displace that volume of water with air at that depth.   I found out there is no power gain.  We are harvesting power from displacing water with air at a certain depth.  But we are getting the air there by displacing that exact amount of water with air by using outside power sources.

I can't comment on boiling.  But I did see a few videos of someone boiling water from eddy currents by alternating magnetic fields under an aluminum bottom beaker.

Well if you think about it that bubble will rise a mile up in to the atmosphere .so you could be pushing something way up there with very little .I was thinking of using a HHO unit and running it @30 psi moving water as in a air water pump 15 ft into the air  and running it down a water escalator on a 45 deg angle .then using the hydrogen in a motor or fuel cell.that's double usage for one action .  no I don't have a link I saw it twice many years ago .it might still be out there on the web I don't know . but using boiling water is simpler its easy to replenish..safe ..and by using a upside down funnel on the bottom of the pot you could move most or all of the bubbles up in to the fans which might look like a jet engine intake .also fire is easy your walking on fuel in the woods .

This reminds me of a thought experiment I came up with many years ago. I never looked into pressures to much. But your post reminded me of what I was thinking long ago.
Through some research, it appears that electrolysis improves up to 65% with higher pressures. If one was to have a very long, and deep column in the ocean, with the electrical wiring running all the way down to the bottom. In theory, it would take less energy to split the water molecules than above water level. Of course the splitting causes, the bubbles which can be used to generate energy all the way up to the surface using boyancy methods you are discussing. You could also draw some energy off of the surface turbulence as the bubbles release under the surface. Then of course, we can get energy still from hydrogen as it is still buoyant in air above the surface. Then of course we can burn the gas after we have generated any energy we can squeeze from it. Burning the gas will form water we can catch for desalinated drinking water. Then we can use the heat released from burning it to generate even more.
Yup. Lame brain idea. But it gets the old noodle moving. Just makes you think of all the natural processes we could technically capture energy from if we could of start the right chain reaction. Is this one feasible, probably not. Just a thought experiment. But sure seems like we can get a lot of possible energy from a tiny splitting of water.

Water also will boil in a vacuum. Just another possible boyancy avenue.
