Then you have to use energy evacuating it. I've already explained that vacuum energy from the engine intake consumes fuel. So does any vacuum pump. If you had a source of free vacuum power that was otherwise wasted, you could simply drive a generator with it directly.

for an example the outside skin of a submarine at a depth of 3000 ft will be apx 1300 psi while a sailor inside the submarine can drink a glass of water at 14.7 psi or 1 atm.


That's beside the point. What's relevent is the sailor can't go for a piss over the side. To do so requires a lot of energy to pump fluid from the low internal pressure to the high external pressure.




here is an example of someone who uploaded a video to youtube about usng the buyoancy of hho to gain the lost energy back.

He's generating the gas at high pressure, so we know why that doesn't work. If he did it in an atmospheric container that moves up and down, he'd have to use a huge force pushing the empty container back to the bottom. If he fills it with water at the top and lets it sink, then drains the water out, then fills it with gas that could work. But he has to keep topping up the main vessel which of course requires a pump.

As usual. Why do these people all have an extreme lack of motivation to finish their projects? Don't they know the future of the planet is in their hands? Would you really walk away from the million dollar gold nugget because you got distracted by a pretty butterfly? But that doesn't matter, he hasn't got a working model so his ideas are as worthless as the millions of other perpetual motion machines that've been proposed but never worked.
