Now use a fuel cell to return the HHo plus O to water making power any time.

@vmelkon and what happens if its container leaks? X[

Should we design solar cells laying on a rod? Because parabolic mirror can focus sunlight on the solar rod facing it. If the solar rod rotates in a constant rate, it may allow itself cooling off when it is not facing the focus light. Perhaps it can even be cooled off quickly by coolant or something spraying on it and wiped it off immediately. It think it can increase solar cells economy.

It's interesting to point out that H2 does the job of electricity, storing energy. If we developed better battery technology or even the fabled ultracapacitors from EESTOR, the whole hydrogen future would be pointless. Hydrogen is very expensive and energy intensive (which subtracts from it's over-all efficiency) to compress and transport in densities that we would require. It leaks from almost any container, and can even absorb into some metals because of h2's small size. We'll see...

yes but the thing is you can use this on an almost "normal" otto engine, and you have free input power so it pays off pretty good.

Probably, the best would be NH3. It is easy to compress and liquify. When you burn it, you et N2 and H20.

where did you get the $50 solar pannel

In commercial applications the hydrogen is stored in all from 300 up to 700 bar! Hydrogen can also be stored in liquid form but needs a temprature around -250 degrees Celsius to become liquid. One thing to bear in mind.. Elecrolyze process is not very optimal. Since it gives out only half of the power you put in. You could charge an electric car with that power instead. You also have to use power to compress the hydrogen and so on...

[ErikGervman]

its not as much the method of getting it, its more the method of storage
