Scientists harness the power of pee

Judy Skatssoon

ABC Science Online

Urine batteries can't power laptops yet, but they could theoretically keep a digital watch working

A urine powered battery the size of a credit card has been invented by Singapore researchers.

A drop of urine generates 1.5 volts, the equivalent of one AA battery, says Dr Ki Bang Lee of the Institute of Bioengineering and Nanotechnology.

He says the technology could provide a disposable power source for electronic diagnostic devices that test urine and other body fluids for diseases like diabetes.

These currently need lithium batteries or external power sources. But with this system, the body fluid being tested could power the unit itself.

TAlk about "renewable energy", LOL.

Well then, we have solved the energy requirements for automobiles now. Just get several batteries, string them in parallel, and fill 'em with pee juice.

This is an interesting article; but the quote is somewhat misleading. Volts are a measure of electromotive force -- not of the energy delivered. Different types of batteries have different voltages -- AA is a size not type.

To continue the thought:

It ain't the voltage that counts, it is the current (amps) or wattage (volts X amps).

Walking across the carpet in your slippers can easily generate 10,000 volts... But it it is micro amps of current. Even at 10,000 volts the best 'work' you can get out of the 'juice' is a flicker in a fluorescent bulb.

Yeah, urine as an electrolyte on the right materials can generate some elecricity, but is is a VERY inefficient one. Vinegar, grapefruit juice or even cola drinks are better. A gallon of the stuff won't run an average light bulb for five minutes.

This statement is just more pseudo science for the ignorant masses.

Oh, I might add, the 'urine powered' batteries is hardly a new thing. I saw my first commercially available one thirty years ago, and remember seeing home made ones 45 years ago when I was a kid.

I have a better suggestion. Someone should invent a urinal with little water wheels in them. The faster we got them to spin, the more energy we generate.

Those taverns near campuses that always have clever names -- Like "The Library" or "Decarte's Clock". New Name -- "The Power Station". Every neighborhood tavern will have enviro-wackos protesting outside the doors.

I have some recollection of being "rippled" but the power I left behind had been lost. Wonder what the neighbors will think when I hook up battery connections to my septic tank - in an ambien moment, of course.

What they don't seem to get is the fact that the electrolyte (urine) is not what gets used up. It's the sacrificial metal (zinc in the old timey batteries) that is consumed.

AA, AAA, A, C, a lot of watch battereies generate 1.5 volts. How many ampere-hours (or milliampere-hours, microampere-hours, or even nanoampere-hours) will this battery generate?

(BTW, I'm pretty sure it is a 'cell' not a battery. Most all cells generate about 1.5 volts.)

Right you are. Any acid will work as an electrolyte with the proper electrode materials.

Yep. Steel hulled vessels have zinc plates welded to their hull so the zinc will be eroded away by electrolytic corrosion instead of brass fittings in contact with the steel hull. The zinc erodes relatively quickly.

Wouldn't it be some sh!t (pun intended) if the technology DID develope over the next few years which enabled everyone to power up a battery with pee and the battery was strong enough to power something like an electric scooter or even a car?

You probably didn't guess from my handle that I used to operate ships for a living for about 35 years. The most critical places where we mounted zinc blocks were on the prop shafts. The props are by far the biggest chunks of brass expposed to sea water and they are very expensive.

It isn't just steel-hulled vessels that need them. Wooden and fiberglass vessels with steel shafts and brass props need them also. The steel hull is not a big factor in needing them. It has more to do with two unlike metals coming in direct contact (prop & shaft) at one point and having areas of both also exposed to the electrolyte (sea water). The contact is necessary because the unlike metals can generate electric current and erode only if the pseudo battery thus created is shorted out (where the shaft and prop touch) and the current can flow.

Without the electrical circuit being complete, it can't happen. Unfortunately there always is a closed circuit, so that's just a 'dream' situation.
