Hydrogen from urine the new path...

[IronHead]

Only if you are doing Magnagas , but that is a different subject altogether
Again urine is about 95% water anyway. So if you use it you are not going to see huge gains in hydrogen output.   
What you will see is abit of a slower burn due to the nitrogen content 

[WilbyInebriated]

see a bit of that up here in farmland, mostly ammonia and hydrogen though instead of nitrogen.

"EXAMPLE 2

Referring to FIG. 3, a cyclic voltammetry experiment demonstrates the electrolysis of urea and urine in an alkaline electrolyte composition. The alkaline electrolyte composition was 5 M potassium hydroxide, the anode was electrodeposited nickel on nickel gauze and the cathode was platinum foil. The cycling rate was 10 millivolts per second. The concentration of urea was 0.33 M, which is equivalent to an average concentration of urea in human urine. A baseline experiment was performed on the 5 M potassium hydroxide alone. The figure indicates that the electro-oxidation of urea and urine behave similarly. As such, the other contents of urine do not appear stop the electro-oxidation of urea.

Under the conditions existing in the above electrolytic cell, a hydrolysis reaction may occur. This would convert urea into ammonia and carbon dioxide. The hydrolysis pathway becomes favorable with increasing hydroxide salt concentration and increasing temperatures. For example, urea samples contained in 0 M, 1 M, 5 M and 7 M KOH at 50° C. for 89 hours produced 0.7%, 4.2%, 27.4% and 36.7% hydrolysis, respectively. A 7 M KOH sample of urea at 70° C. for only 24 hours provided over 95% hydrolysis. The hydrolysis reaction is shown in the following reaction.


CO(NH 2 ) 2 +H 2 Oâ†'2NH 3 â†'+CO 2 â†' (Overall Hydrolysis Reaction)

Thus, reaction conditions can be modified to promote NH 3 production over H 2 production using an applied voltage. In some instances, H 2 production will be preferred."

ironhead, you almost made me spit out my soda.

That would be a valueble (albeit slight) waste of urea. Glad you held that one in.

Group,

Experience from my youth with rabbits, it would be easy to
construct waste separating housing. You get meat, solid
fertilizer and now ENERGY!?  !!! If memory serves???,
rabbit urine was concentrated. A pregnant cow if you could
capture the urine they release what seems like a gallon or
more each time they let go. Also extremely strong P smell...
+++++++

Everyone that says NOT to P in your booster cell is right.
First one side of each plate or other surface must be nickel
plated and the cell voltage must be reduced to 0.37 volts

will pulsing continue to increase efficiency? The frequency
will have to be determined. Then once the water electrolyte
is depleted of urea it will have to be removed.

So far sounds easy enough for anyone thats made a water
hho system...  except now we can use galvanized maybe..

For those that want to use Human P, morning P is strongest.

I have my fingers crossed that we get CO out too!, 2/1 ratio
as its excellent medium compression engine fuel. Just mix all
with air and burn. The nitrogen, hydrogen and carbon monoxide
is like woodgas or producer gas BUT would seem clean from the
start UNLIKE woodgas or other producers.

Group,

I want to add that it takes one action with water
at 1.23volts across each cell to make ONE H2.

With urea its two H2 and maybe a CO per action.
At 0.37 volts. Energy requirement problem solved

If the old H2 way is/was "simply and energy carrier",
then this is a robust energy source! and its available
all the time.

A true and robust biofuel.

The waste water can go into any sewer in any city
and us rual folks can drop it in a ditch. no different
than a deer taking a P. and farmers can have two
collection ponds one for hi urea waste and the other
for the water thats had its urea removed....
