Create a Lemon Battery

Purchase: http://hilaroad.com/video/ Creating a battery from a lemon is a common project in many science text books. Successfully creating one of these devices is not easy. This video demonstrates how to construct and use a lemon battery to light an LED and operate a calculator.

you can do the same thing with potatoes.

so wait... if lemons make electricity.. and there are cars that run with electricity, we could run those cars with that electricity instead of using and producing cars that run with gasoline.. that would be a great way of reducing CO2 in our air because we would also have to plant billions of lemon trees which would of course make photosynthesis.. that would be awesome let's do it!!!

Everyone here seems to believe that the energy comes out of the lemons.

It does not.

It comes from the reaction between Zinc on the nail and Copper on the penny.

The lemon just act as electrolyte

@ScHnitzLLlicious92 even a very tiny extremely low voltage LED needed 4 lemons to barely glow a little bit, in your case we will need a truck of lemons following us to supply enough lemon to run the power-eager car engine at 10kmph ~6mph

just to be clear, one drip of gasoline has more power than a box of fresh lemons

well you know what they say, when life gives you lemons, make a battery

thanx it really works and it help me a lot in my schools projects................

[Gapcoproductions1]

Very cool I can't wait to try it :-)

The point is that a lemon provides the circuit even with a huge internal ohmic resistance, thus the reported voltage value is correct only because the measrumement device doesn't need a sensible current to measure it and it does not allow the current to flow along the series.

But the very time you inset a load on the series, allowing the current to flow along, the internal resistance lowers the available voltage for the load (i.e. the LED); thus actually the effective output voltage is smaller.

nice demo ... i wander what current flows though a citric acid battery as the one build by you :-? ... if you do the measurment i would like to get a link :D

[mochalisa24]

thank you very much. this video helped me a lot in our investigatory project.

[glivarbrostv]

im using this as my science project, but im giving you credit

[raywesful]

Thanks. I'm doing that in class and i had no idea what is was. This explained itself so well! Thanks again!
