make a battery
Bookmarked 696 weeks ago is there free energy hidden inside your pocket change i hack pennies into make-shift batteries that can drive small current devices like led039s and calculatorshttp:wwwthekingofrandomcommusic by kevin macleod - pure attitudehttp:incompetechcomwarning: use of this video content is at your own riskfor this project i039ll need pennies my neighbor trevor gave me these and i039ll begin sorting them by date i want pennies newer than 1982 because they039re nearly 98 zinc ok i039ve picked out 10 pennies that i think will work so i039ll use this 100 grit sandpaper and start sanding one side of the penny actually this may be too much work so i039ll try some double sided sticky tape and an orbital sander this is working much better to expose the zinc but the adhesive has melted from the friction and left these pennies in a sticky mess no problem i039ll just use some adhesive remover to clean them up and now they039re looking great it039s time to build a battery i039ll cut some thin cardboard into pieces just bigger than the penny and throw them in some vinegar while those are soaking i039ll start my battery cell by placing one of the pennies with the copper side down on a piece of aluminum foil as you can see nothing is happening yet so i039ll blot dry one of my cardboard pieces and place it on top this time when i measure the voltage i039m excited to see over half a volt from this one cell i039ll add another penny and cardboard and repeat the process until i039ve stacked up all my pennies now the cells are connected in series and the electric potential has jumped to nearly 6 volts wow this should be more than enough voltage to drive an led so i039ll test it out with this one it works perfectly and i can039t believe how brilliantly this lights up just for fun i039m testing the currant draw and it039s pulling about 170 microamps i can even light up two at once ok so it works and it039s actually really impressive that i039m getting electricity from pennies but now i039m curious to know how long this can last i039ll use some electrical tape to hold everything in place and try to fix these cardboard edges because they shouldn039t be touching i039ll do my best to make it air tight to prevent the wet cardboard from drying out too quickly and then carry it with me for the next couple of hours to watch when for it dies out ok so now it039s more than 2 days later and i really can039t believe what i039m seeing the green light is still on which means these little pennies are still pumping out juice this is awesome so i want to try another idea i039ve picked up a calculator from the dollar store and i039ll remove the screws on the back so i can get to the battery once that039s removed i039ll pull the negative and positive leads out of the casing and now i039ll need to make another penny battery this time i don039t feel like sanding the pennies so i039m adding these zinc washers i got from the hardware store for about 3 cents each i need around 15 volts so i039ll use 3 pennies 3 washers and 3 pieces of cardboard soaked in vinegar this time i039ve rounded the cardboard edges so they won039t be a problem and i039ll stack them with the washer on the bottom the cardboard in the middle and the penny on top this is one cell and i need 3 so i039ll stack up 2 more the penny on top is the positive side and the zinc washer on bottom is the negative i039m getting just over 2 volts and 700 microamps so i039ll add wires to the terminals and use some more electrical tape to hold it together time to test it on the calculator i039ll press the quotonquot button and it039s incredible the calculator fires right up i039m testing out a few functions and everything calculates correctly so now i just need to clean these wires up a bit i039ll chip holes in the casing and hardwire my pennies into the battery leads then tape the penny stack to the back a penny powered calculator i really am impressed at how well this worked out and still patiently waiting for this little green light to die out well there039s an energy idea that039s worth a few cents that039s it for now if you liked what you saw please take a second to quotlikequot this video and share your thoughts in the comments below to be notified when i post new videos click here to subscribe to my channel i appreciate your support thanks for watching |
