Urine flammable gas and Urine powered generators
« on: November 17, 2014, 09:51:39 AM »
This is something we all have plenty of and can easily get plenty of.

May not be free energy but it is abundant energy.

Yep, and when he gets money for more research you will never hear of this again. Electrolyzing anything is always less efficient than what you get, whether its pure water, urine or feces.
 This is a new form of Nigerian Scams.

I have a security case in Holland full of valuable feces.  If you will just pay the Grand High Court export license fees the case can be released to you.

The amount of voltage it takes to break a urine molecule is less than the amount it takes to break the hydrogen molecule in water.

Exactly how much voltage does it take to break a urine molecule, I wonder?


Sounds to me like someone is just taking the piss.

it doesn't sound like it is a new idea:

Theoretically, the cell voltage for the electrochemical conversion of urea to hydrogen is only 0.37 V, whereas water electrolysis, a popular electrochemical method to produce hydrogen, requires 1.23 V to split water into hydrogen and oxygen. Hydrogen gas produced from urea electrolysis does not require any further purification.

Would you please provide a sketch or a reference for a "urine molecule"? Urine is not urea. Urine contains only 2 to 4 percent by weight of urea. Most of the rest is ordinary water. There is no such thing as a "urine molecule".

above my pay grade to analyze it ... i just produce ;)

just passing along what i found looking into it and again it doesn't look like it is something new - going back to 2009.  the following states that 'The group initially tested their process with 'synthetic' urine made of dissolved urea, but also showed that the process works just as well with real human urine.':

Actually none of this is new. It actually takes less energy to break down urine or urea in solution into hydrogen than with water electrolysis, there is a lot of well documented work on this at Universities. However I thought this was a good tongue in cheek story. It was not meant to fire up the lynch mob lol

No lynch mob, exactly! Just the usual complaints about proper use of terminology ("urine molecule" cracked me up) and the examination of the numbers.

For example the concentration of urea, OCNH2NH2 , in "non-turbo" urine is pretty small, like 4 percent or so, and the urea molecule masses 60 Daltons of which only 4 are the 4 hydrogens. So less than 10 percent of the urea, by mass, is hydrogen. So that is not much hydrogen from the urea in normal urine, I think. So perhaps it is easy to split off the hydrogens, or some of them, leaving things like ammonia and perhaps free oxygen or even HCN behind. But how much hydrogen and other (very toxic) gases are you going to get from urine, really?
Does the urea somehow catalyze the electrolysis of the water itself? That would be cool but I don't see how it could happen. But I'm no electrochemist after all.

All you really have to do is to pee on an electric fence.  I have done it...I do not suggest anyone else try this.  Ah, I miss the old college days.

Perhaps....an advantage is being recognized and exploited this way:
 
The electrical resistance of pure water is relatively high, causing electrolysis of such to waste energy in the form of Joule heating resulting from said electrical resistance.

The electrical resistance of urine is somewhat lower, therefore less energy is lost to said resistance during electrolysis.


Perhaps a similar advantage exists in electrolysis of water containing ANY good-functioning electrolyte, which makes available generous quantities of dissolved ions, not just urinistic electrolytes and their ions.
