How To Make a 3 Penny Battery

Is there energy hidden inside your pocket change? Convert pennies into make-shift batteries that can drive small current devices like LED's and calculators.
Many people have asked how long the green LED stayed on. Surprisingly, it was bright for 2-1/2 weeks before finally fizzling out!

Project History & More Info:
LEGALITIES: Some people have asked about the legality of treating pennies in this manner. The federal law states that there are exceptions made for use as "educational, amusement, novelty, jewelry, and similar purposes as long as the volumes treated and the nature of the treatment make it clear that such treatment is not intended as a means by which to profit solely from the value of the metal content of the coins." For more information, see: www.federalregister.gov/artic...
This is a wet-cell battery. Pennies newer than 1982 are nearly 98% Zinc.
The redox reaction between the copper and zinc metals allow electrons to flow and each cell provides around 0.6 volts of electric potential.
Here is how to light up an LED and power a calculator using some loose pocket change!
I found this link that helps explain the reaction and why it works: www.science.uwaterloo.ca/~cchi...
Basically, a galvanic cell consists of at least two half cells, a reduction cell and an oxidation cell. Chemical reactions in the two half cells provide the electrons for the galvanic cell operations. Copper ions gain electrons (reduced) while zinc ions give them up (oxidized). = (redox)
An electrolyte like salt water or vinegar helps get the metals into ions. Electrons flow through the electric conductors connecting the electrodes, as ions flow through the salt bridge.
The overall reaction of the galvanic cell is: Zn + Cu2+ = Zn2+ + Cu

[@normalnate3447]

There’s a lightbulb in a fire department that has been on since the beginning of the 20th century and it’s still on and working

[@TrevoltIV]

@@normalnate3447 That makes sense because contrary to popular belief, light bulbs take a lot more damage when you turn them on and off all the time versus just leaving it on. When it goes from cold to hot immediately, it stresses the filament. However if the filament is just constantly glowing, it doesn't stress anywhere near as much. Although it still will go out eventually.

[@Shipprofile08]

this is amazing! i wonder how many of these pennie batteries we would need to power an electric car? I'm sure its in the thousonds lol

[@spectatormag946]

How many pennies would it take to power a 300 watt computer? (of course its a scrap computer) Since its dc I would need a power inverter but how would I even begin to calculate this? Yes, I'm aware its not practical but its just an experiment that I would love to try. Also, would I need to make up a bunch of penny cells and put them in parallel or series?

[@CrazyGaming755]

about 1000 pennys? xD

[@spectatormag946]

Crazy_Gaming lol thats a nice round number but something tells me its going to take a lotttttt more. Haha

[@unnamed130]

Ha, then I need about 3500 to power mine!

[@insaneAnimeLover]

Well, each penny gives you about 0.6V and 500µA (= 0.0005A). So you would actually need 1 million pennies. 0.6V * 0.0005A * 1 million = 300W. But the good news is you don't need an inverter. PC power supplies can run on AC or DC. You could make a stack of 333 pennies to get around 200V and then put 3000 of those stacks in parallel to get the current up to 1.5A But why not try it with a cell phone instead? Then you'd only need 3000 pennies.

[@spectatormag946]

spider pig Finally! Thank you! Well as far as the cell phone goes ive see endless videos powering them. I need more of an awe factor. (i get bored very quickly, very lol) Anyway, Thank you again, i really needed some type of foundation to start with.

I would think so, just replace the soaked cardboard

[@angrycreeper100]

the real question is will it blend

[@rosemarycaldwell8751]

ya

[@AcLaMaDoR]

The reaction happenning is a flux of electrons from the copper to the zinc so no, it won't recharge unless you apply the same amount of electricity in the inverse way to undo the reaction, source this is a basic redox chemistry reaction and I'm studying chemichals engeneering vinegar only acts as an acid solution to help the flux work

[@angrycreeper100]

so does the copper run out or something

a conventional light bulb works with AC-volt, a battery puts out DC-volt. so it won't work for a second

[@sc0tte1-416]

Okeanos86 A conventional bulb will work on either AC or DC. It's just a tungsten filament that heats up; it doesn't matter if the current is alternating or not. Light bulbs in cars ect work the same way and they are on DC. Bulbs with electronics however probably won't such as compact florescent.

Well it really depends in today’s world! There are units that use DC to run, but what type of A/C are you thinking of?

And for how long are we talking about for these setups to run? You might be better off getting solar panels a bunch of car batteries and a power converter to run a window A/C then a penny battery, at least the solar can be recharged each day!

[@sagecorradini9734]

We made these at my old job, and arts and crafts kind of place. Super cool!

[@MrTerminalZ]

If 10 pennies = 6 volts, and a standard light bulb uses 120 volts... You'd need 20x the volts and therefore 20x the pennies. You'd need 2$ worth of pennies to light a single lightbulb. The real downfall is the space it takes up.

[@CST1992]

+MrTerminalX It won't work anyway. You are forgetting that the light he uses is a LED, not an incandescent bulb. A regular bulb is incandescent. Assuming 30W bulbs, you'll need 250 mA current at 120V to power up the bulb to sufficient brightness. Doing the math, you'll need 10,000 stacks in parallel of 200 pennies in series each, plus a DC-to-AC converter to light up the bulb. Ignoring everything else, you need $20,000 in pennies for your experiment. Plus, it'll take a hell of a lot of space.

[@mattr4198]

+MrTerminalX Normal light bulbs would require A LOT more than the couple milliamps the pennies would put out.

can you show us how to convert a wireless mouse to a wired mouse or wired to wireless?

[@YoniTan]

Why would you or even anybody want to convert a wireless mouse to a wired mouse? Well if YOU do, here you go: Click "Read More" 1. Take apart the wireless mouse 2. Remove the transceiver (save it for a future project) 3. Find a wired mouse 4. Cut the wire where the wire meets the mouse 5. Shove the wire up the wireless mouse's ass
