The Voltaic Pile

[blueshift314]

when multiple cells are stacked together, why does the charge not move directly from a penny to the zinc washer it is touching?

alguien qe hable español por favor me puede dezir qe materiales uso por favor !!

[abcd19263]

why is the copper positive and the zinc negative and not the other way around

[Rique6590]

Thank you for this enjoyable video :)

[fermixx]

how much time does the current last? Guess its not eternal..

why should i buy an energizer and not put some pennies togheter?

[robbylafont]

@fermixx

add up the cost of the pennies, the zinc washers, the aluminum foil....and you'll see that buying the battery already made is the sensible thing to do....and takes way less time...not to mention...most electrical devices are designed for the shape of a pre-made battery....

As Nurdrage say:

Hmmm...and I think most Americans are misinformed in thinking that all electricity comes from coal, and thus the electric powered car would be inefficient...but as we see here, this is not the case. Start collecting your pre-1982 pennies, people!

[georgeisin]

@3beavers coal does poduce electricity in a different form. By burning coal to heat water you generate steam which is used to turn a turbine generating AC electricity (alternating) which is more efficient to transport through powerlines.

vinegar should work better than salt water. lemon juice works too.

Best Video On YouTube.

[giantsinister]

voltage!!!

[jcbass]

Excellent

[clownstangler]

so electricity does come from thin air

we think we have a lot to learn... but realy we have a lot to realise

[M3n747]

A very interesting video!

[Scrap5000]

Italians always rocking the house!!

[FingerboardOwner]

Always interesting :P finaly an other vid of ScienceOnline :D

[itsabomberscope]

incredible!

[whatisunknown]

I actually learned something new!

[heven729]

Excellent video like always!! Hope you're having a great summer!

[BryanBeatsYouAll]

I...

...I find this interestingDON'T JUDGE ME

[hellstudios]

I'm guessing that the thing that makes these run is the salt water?

idk, but how long do these last?

[pale1221]

guessing until the strip dries

[hellstudios]

that's a good answer.. "how long do these batteries last?" "until they die"

LOL.

[Incuby]

Good questions ;)

[cool70200]

nice video, thx

I thought about doing similar and looking into making water batteries.

It could be useful in a alternative "off grid" energy set.

Link up enough voltaic piles to get 12volts to use to store into a deep cycle battery at nights or off weather days, to switch from solar panels, wind turbines, solar created steam power, or gravity fed water turbines.

I just havent figured the cost of temporary galvanized zinc and copper plates vs cost or benefit in electricity gained.

[cool70200]

too bad we cant get electrons to flow from plastic or paper eh

[TheReasonWhyGuy]

excellent video!

[sciencenerd1616]

can you recharge them and how long do they last ?

[zammyzhere]

how long could those 4 piles make the led run? also, is it possible to charge an ipod or phone with the voltaic pile?

[hellstudios]

yes. it is possible to charge something. :P

[MaxZagar]

Thanks, I will do an experiment like this :)
