Hydrogen from urine the new path...

[Farrah Day]

That is correct I really wish they would have mentioned the amount of current used for the application indeed unfortunately I did not recall reading that information but I will see if I can dig up the current specs some how or another

It doesn't matter what current they used, it's irrelevant in this context. The fact that they can do this at .37 volt instead of 1.23 speaks for itself.

If the electrolyser draws 20 amps with water it dissipates 24.6 Watts of power, if the electrolyser with urine draws 20 amps it only dissipates 7.4 Watts of power.

This is far more efficient than any electrolyte I know of.

You will discover that the initial voltage drop from using your urine is because of its increased conductivity... one of the many problems with this is that your urine has a sulfur content (diet dependant) and this will produce a nasty gas with your O2...

The unfortunate thing is in order to overcome the resistance of the water you need X Voltage. You can lower the voltage by shrinking the gap between the reactive surfaces or by decreasing the waters resistance with additives...

I think your missing the point here Crazy person.  Apart from the fact that it is the H2 that is required, not the O2, I think your also probably confusing sulphur with ammonia, and it's not about increased conductivity.

use urea fertilizer, urine is 95% water
Have fun and wear a respirator while experimenting

Nice.  Urea boosters.     But the Feds wouldn't appreciate fertilizer being used  for "unintended purposes" heh.

How about Screw them , they dont even want you to use water these days with out them knowing about it.

How much hydrogen could be obtained through 95 percent urea, and how is the cost effectiveness?
