Power in has to be less than power out. I don't believe this is possible using oxygen generators. Why not just use a reactor?You know, with all the technology we have today, there should be a safe way to harness the hydrogen and make it safe.
Besides..................making your own power from the very water you are traveling through would be the ultimate green vehicle.
I mean................companies have made hydrogen powered cars, why can't they make subs?
You're not making any sense. And the oxygen generating process that the scientist showed on the television didn't take that much power.
By the way, you wouldn't be using an oxygen generator to make power, you would be using the resulting HYDROGEN that comes from generating oxygen, and hydrogen is a pretty decent type of fuel for making energy.
And.....................got news for you..................just about every U.S. Navy submarine has a reactor for power.
The only reason I brought up the hydrogen thing is because of what I'd seen on a documentary on subs.
