I came across a video about a scooter that runs on water on Facebook and everybody is talking about how this could be used but gas companies kill people who bring it forth etc....
So I thought I'd do my own calculation on it but not being a scientist and only getting basic chem about 10 years ago I got stuck, here's what I have so far:
Water = H2O (2 Hydrogen molecules for each Oxygen molecule)
Energetic Value Hydrogen = 141,86 MJ/kg on burning and you need 1 Oxygen molecule per 2 Hydrogen molecules in order to burn it. (https://en.wikipedia.org/wiki/Energy_density)
1l water = 1kg
1l water = 666g H, 333g O
0,666kg * 141,86 MJ/kg = 94,48 MJ
1MJ = 0.28kWh
=> 94,48 MJ * 0.28kWh/MJ = 26,45Wh
So if I split water using electricity I'd get about 26Wh of energy from it if I burn it, but I can't find how much energy I need to split one liter. I've read you can use a 9V batterij for example, but how much mAh should it have to split 1 liter?

The exact same amount. Or realistically, more than that, since no process is going to be 100% efficient.
It is physically impossible for any cycle (in this case water to H and back again) to result in a net gain in energy.

> in this case water to H and back again
What do you mean back again, it just has to go to H, not back again?
I just found this post however:
https://www.quora.com/How-much-water-can-you-split-into-hydrogen-and-oxygen-using-electrolysis-with-one-kilowatt-hour-of-electricity
"1 kilowatt hour of electricity can split about 270 grams of water"
270g water would give an energy of about 7,14Wh, meaning you'd have less then 10% efficiency, so that settles all the bullshit gas companies hiding the free energy from us.
HHO engines are an OLD scam and have never actually worked.

Burning hydrogen results in water. Burning is just combining with oxygen. H + O is H2O. So yes, if you split water and then burn the hydrogen you end up back where you started.

Forget pleb physics, find the secret patent.

So... Just an electrical veicle?
H2O + energy = H2 + O2 = H2O + energy
Doesn`t make sense.
The only way to obtain serious amounts of energy is taking matter and turning into energy
