Urine Powered Battery Developed

Saeed al-Sahaf writes "Research investment into developing smaller and cheaper chips to process information in disposable health tests has been significant, but they were still reliant on an external power source. The researchers at Singapore's Institute of Bioengineering and Nanotechnology think they have overcome this problem with their latest urine powered battery. From the article "The battery is composed of paper, soaked in copper chloride, sandwiched between layers of magnesium and copper. The whole thing, once laminated in plastic, is just a millimeter thick, and 6cm by 3cm in size." The breakthrough promises a cheap and disposable power source for home health tests."

      My dad had an old Model T with an actual engine starting crank. Do it wrong and it could backfire and break your arm. I wouldn't call it convenient either, unless you're some sort of armwrestling champion.

      Actually I always thought hand cranks were very convenient. Never had a Model T, mostly tractors or stationary engines. You are correct that they can be dangerous, but that has very little to do with convenience. There are many things that are convenient, but not safe.

      Regardless, seems to me it wouldn't be hard to engineer a hand crank that is a little safer than the one on the old Model Ts. Something with a one-way clutch that can't pop back and hurt you. Maybe with a gear reduction so it's easier to turn. Many of the engines in modern cars are smaller than the old Model T engines and probably turn easier, so a crank could be a viable option.

      There is one device that does it for primary or backup starting of diesel engines. It has a pull cord like a small gas engine and the first 10 pulls primes the spring and the 11th starts the cranking. It can crank engines up to about 14 liters in size if I recall correctly.

      I have started large trucks by rolling them as well but as for pushing them anywhere well thats not going to happen (I have managed once to push a smaller truck that weighed about 18000 lbs but only a few feet on level ground). I used my Tahoe to pull start a tractor (semi truck) but first un-coupled it from the trailer. Automatic transmissions are a bitch to roll start because you have to get the vehicle up to the torque converters lockup speed before the engine will begin to turn.

      How is this new?

      Near as I can tell, it's new like most everything else is new -- the folks who slept through basic science classes missed how simple galvanic cells work, and now they're surprised by PR from an engineering firm whose employees didn't sleep through science class.

      For those just tuning in now, Wikipedia has a nice explanation of this cutting-edge 1780 technology.

      For those inclined to experiment, stick a copper rod and an iron rod an inch apart in the dirt in your backyard, and piss in the space between them. Connect wires to the tops of the rods and then to a voltmeter. Wooooeee! You've got current. And you can recharge every time you need to pee.

      Of course, technically speaking, you aren't recharging anything. Rechargeable batteries involve a reversible chemical reaction, while a galvanic cell just slowly dissolves its anode and cathode in the intervening electrolyte. For the purpose of providing a feeble current to a disposable medical device, it's not a bad idea. The battery is, however, really old news -- like more than three hundred years old. It's the microelectronics that can take advantage of such weak currents that are the real news, but those aren't exactly at the bleeding edge, either.

    So, let's get some facts...Jeeves says that normal humans feel the need to urinate when they hold 150 - 200mL of urine in their bladder. 200mL sounds decent for this math.

    200mL / 0.2mL per battery = 1000 batteries that can be charged on a normal fill of urine.

    1000 batteries * 1.5 mW per battery = 1.5 W
    1000 batteries * 1.5 V per battery = 1500 V

  31. It can be done. by hellomynameisclinton · · Score: 2, Interesting

    If you can rig up a system to spin the alternator (by re-mounting the alternator and using a jacked-up wheel with a belt for a flywheel), you can generate the ~14 volts needed to charge a 12V battery (charge voltage must be higher than discharge voltage - I won't explain that here, look it up), and with no fancy tools, you can recharge the battery enough for a start-up within a couple hours.

    That's with NO special tools. If there was a crank system designed into the car, efficiency would increase so much (you also wouldn't have to remount the alternator) that you could get the car started with 10-15 minutes of cranking (and one hell of a tired arm).

    The biggest problem with the ad-hoc system is that modern alternators require a starting voltage across their inner coil in order to BEGIN charging (again I won't explain here), and without a special system, you would be relying on residual battery voltage for the alternator start-up. If it was planned for, the crank would start by juicing the inner coil, then transition to spinning the alternator once the coil is charged and feeding back into the car's battery.

    With all due respect, not knowing the solution does not mean there is no solution.
