Well, the plan is like this.
He thinks that you need a low electricity source to electrolyze water and than he wants to use the hydrogen to let a engine run on it to make much more electricity.
We were now thinking of buying a windmill.
With the windmill we could electrolyte water to make hydrogen and with the hydrogen we could power a power generator.
Now my brother is a big thinker, and i am having my doubts about this.
