Here is something interesting

"This is one way to make Hydrogen from waste materials, result in fuel and fertilizer.
H2SO4 + Zn coated Fe = H2 + ZnSO4 + FeSO4 + Fe
Now take the ZnSO4 and the FeSO4 and add NH3
ZnSO4 + NH3 = (3)H2 + Zn + NSO4
FeSO4 + NH3 = (3)H2 + Fe + NSO4
This process uses no electricity, can be made at room temperature by putting the materials together.
Just one of a bazillion ways to make hydrogen, clean, safe, and non-toxic when done! "
I did a quick test and made Lots of bubbles.
