@@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.
Grant, I love you videos and I have tryed many of your projects. I love doing these projects, and I even did this one! I had lost of fun with it and my Dad thought it was amazing. Thanks!
Hey Mr. Thompson, I stumbled across your videos and found really interesting and cool. This one how ever really caught my attention. I tried it and it out and was really surprised. I was always interested in free energy so as another idea for a new video for you I thought of trying to create a small cost effective generator using neodymium magnets. it always runs and never stops.
Unlikely, since the battery becomes a greater resistor the bigger it gets. Eventually, I think, the current will get so slow that it won't be able to power anything.
Made one a little different... instead of cardboard I used a blue shop towel. I got only 3.6 volts but still 2.5 under the load of an LED. These batteries tend to die when the viniger drys up. We will see how long mine will last.
I was looking around for similar videos and this is the best one on making your own coin battery. You'd think there'd be stinking piles of them, but nope you have cornered the market.
Does the United States still use pennies? Canada doesn't so I guess I have a reason now to make a MEGA battery! I wanna see a few BIG stacks that equal over 1,000 pennies to see if it can power a few household appliances. Or see how long it will power a 100w conventional light bulb!
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.
This is a nice modern adaptation of the Voltaic Pile invented by Alessandro Volta and Giuseppe Zamboni. And, although pennies are, in fact, "Legal US Tender," doing this to them for science, educational, or novelty use is allowed, as an exemption for pennies only. However, if one were try to "Novelty" a penny to use as a dime, that would eventually get a visit from the Secret Squirrel Service. And it would definitely not be worth the charges filed.
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
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? A car unit, a window unit, a whole home forced air unit, I would imagine all could be powered by pennies. It’s just each example would need different setups to get each one a working model. 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!
Too bad coins in Germany don't really have Zinc in them... God dammit Germany,nothing he can build I could build,because you either make it illegal or just don't let it happen! :/ xD
Use a washer (not the washer machine lol) a washer it's made of zinc or nickel I think. I just proved it with copper, a washer and vinegar and it works perfectly !
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.
+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.
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?
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.
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.
It was a great idea to use double-sided tape during sanding. We are using a file to expose the Zinc. My question is, where did you find the micro-Amp LED? I have been looking!!
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.

This is what Volta did with the zinc, salt water soaked paper, and copper. It’s a neat little trick but not ground breaking. You probably learned this in high school! Lol
I am curious. Did the light "fizzle" out after 2.5 weeks because the vinegar in the cardboard dried out? If you re-soaked the cardboard would it have relit the light?
Well? When did the light finally die out?

I need 5 human size penny's lots of card board and can I borrow some vinegar I need to power my house
I'm a bit curious... did the penny battery with the green light on run out yet? if so, how long did it last?
Who needs normal batteries when you've got science? (And Abraham Lincoln)
Hey Mr. Thompson, I stumbled across your videos and found really interesting and cool. This one how ever really caught my attention. I tried it and it out and was really surprised. I was always interested in free energy so as another idea for a new video for you I thought of trying to create a small cost effective generator using neodymium magnets. it always runs and never stops.
how it work out for u
free energy is impossible
@@funnyduck4568 The Earth itself is a lump of energy. Hence, most energy we see is free.
Quick question: If you're buying zinc washers up front, does it still matter what year the pennies were minted?
I get the feeling this guy's going to be living it up during the apocalypse,
meanwhile everyone else is fighting over batteries.
The only problem our great great grandchildren will have if there is no apocalypse is finding a username that isn't taken already!!!
Grant Thompson - So would it be possible to take this penny battery to a higher level? like running something that needs way more power?
M Hayos technically yes, realistically no.
mathematically, yes
Physically, yes. Start collecting pennies now, the apocalypse is coming soon
Unlikely, since the battery becomes a greater resistor the bigger it gets. Eventually, I think, the current will get so slow that it won't be able to power anything.
Soulsphere001 yeah as the current running through will have to go to cells
That's so cool! I never thought just a bunch of pennies could make so much electricity!
It's mainly the vinegar cuz of the electrolytes in it
would this mean that were paying for the electricity, or were gonna get "refunded"?

MrPypap So I've been told a time or two. What's your reason for thinking I'm a mad-man? :P
a conventional light bulb works with AC-volt, a battery puts out DC-volt. so it won't work for a second

But will it recharge?
I would think so, just replace the soaked cardboard

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
so does the copper run out or something
whats the max power you can make?
another words if you keep adding pennys will you be able to power an air conditioner?
Maybe if you take out the capacitors it might work
