Pee-powered batteries!

Postby MM_Dandy » Wed Aug 17, 2005 5:09 pm

Scientists have developed a way to turn pee into electricity. And there's plenty where that came from, they point out.


How much power can you generate?

Not much, appearantly.

Cheap, disposable, and renewable, urine-powered batteries may be the perfect power source for disposable healthcare test kits called biochips, the researchers say.


But really, I don't think they've really explored the potential here. I mean, give me three or four beers, and I'll bet you I could keep a lightbulb lit for at least a minute or two!

I am afraid that this isn't new. You could buy urine powered emergency flashlights for years (not good if you pee your pants when the lights suddenly go off :D ). I use to keep a couple on the boat (they can use seawater also) for emergencies - got rid of the boat and the kids got to use the flashlights last Halloween (don't ask me why it was a thrill for them but they loved it).

The amout of energy depends (that wasn't intended as a pun) on the size of the battery and the amount of urine.
"Mars" is also a chocolate bar found on Earth. These are highly concentrated sources of carbohydrates, which are of vital importance to many carbon based life forms. Mars bars are slightly rippled with a flat underside. They are sometimes used in English courtship rituals in which the female performs various allegorical oral acts with the chocolate bar, which is donated by the male as part payment for this spectacle.

Urine has moisture and electrolytes in it, so yeah sandwiching it between dissimilar metals will produce an electric current. When I was a kid I had a series of those Radio Shack project kits and there was usually an experiment in the instruction book involving making a battery with 2 coins and a piece of wet paper. Thinking back on it now, they never did say exactly what to wet the paper with. :D

But using the test substance as an electrolyte is, AFAIK, new.

That reminds me, I need to get some more 9-volts. :D

I used to shock my self quite a bit when I still had braces. I'd wire a 9-volt to two wires, twist one to my lower arch-wire, and then place the other wire on my upper arch-wire. My head completed the circuit. Then I'd see white flashes like a strobe light and my jaws got numb! I learned not to leave the circuit completed for more than 30 seconds because my teeth got really hot and I'd start to drool. :?

For once, I have to say I miss my braces. I have a metal retainer attacted to my lower teeth, though... maybe I should go get a filling in one of my upper molars! :D

Whoa there fella...

Sell her?

I have no desire to sell her at any price. And I think those qualities are what gives her value.

Yes, didn't you follow the thread where hippe was trying to sell her friend?

Maybe you would like to buy her then? :D

Nope. Not a word. I think that just makes her, um, "resourceful".

And then you have a bridge in Brooklyn available too, don't you?

Why would I have to buy her? She's already here.

Certainly! And at a good price, too!

There, see what you have done, hippie? I should have sold you before you told that story about your braces and the battery... :evil:

:lol: You can only sell me if you can find me. And I bet there's enough information out there to find me...

See, now, Khrushchev, you can't use my own ideas against me... they just don't work out for you in the end... :P

P.S. I rather like being electrifying. Or electrified anyway...

Ah, another valiant, but ultimately futile, attempt at steering us back on course. :wink:
