It will always take more energy to extract hydrogen from water than the useful energy we will get out of the hydrogen.

Given the geometric progression of technology, it is impossible to make a claim like this with any certainty.

Only if you have a weak understanding of physics.

Besides, I didn't say this was the answer. I said "hydrogen fuel cell LIKE" power source.

What else is "like" that?

What I meant by that was something other then fossil based fuel.

You mean a fuel source that doesn't use more energy than it gives? Yeah, that would be a better answer to our energy needs. Try something that actually has energy in it already, like oil, coal or uranium.

I believe I mentioned cold fusion.

Given the geometric progression of technology, it is impossible to make a claim like this with any certainty.

Only if you have a weak understanding of physics.

Above statement indicates you know absolutely everything to be known about physics and that no technology can ever evolve that will provide a power source that will make extracting Hydrogen from water cost effective.

Have I got that right? If so can you explain why that would be true?
