Hydrogen Production with Sunlight

[johnnnyreb51]

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

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...

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

[simpsonstewie]

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

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...

[spallcast]

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.

[ErikGervman]

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

@ErikGervman they are gunna use cicken feathers believe it or not

I hope someday we could put this in our cars (safely) and get rid of oil.

Try putting two tablespoons of bicarbonate of soda in one quart of water and at least 8 ounces of isopropol alcohol. After chargeing up this solution for several minuets, just add a cap full of hydrogen peroxide and turn the electrical power off. See how much gas you produce then :)

Now this is what I was waiting for. And remember, that's NOT over-unity: we're simply using the largest nuclear reactor available almost to everyone, at 0 cost... THE SUN! Now, my question is: is it possible to store HHO gas without reverting it to water?

[segarza]

Store it as electrochemical energy in batteries. Compressing HHO to store it, is very dangerous. One little static spark and the whole thing will blow. Checkout that video of a huge HHO balloon exploding and I think you will see why.

[samoht1977]

Yeah, I suppose it's dangerous to compress HHO to store it... but isn't propane or methane dangerous too? yet a little spark and everything will blow up either, isn't it?

[espido]

how do i store the energy ?

[oo7maskman]

Thanks for showing us this - The solar panel costs $50 bucks plus some semiconductor device. How much H can be generated from this size of solar panel? Looked like quite a lot of bubble action happening. Could a similar device be used to make a carbonated drink on camping trips? Bottom line - it left me wondering what would happen if you leave the cork on - eventually I guess it would explode.
