If potatoes can generate power can oranges be far behind?

Almost all liquid containing vegetables and fruits can generate power. Actually all that happens is that the more electro positive electrode dissolve in the fluid, which always contains some minerals or acid. Generally these are more school projects.
Here is one more such using an orange. Very creativlely, I must say.

    Sir really interesting.😀
    If the electricity is due to the reaction between citric acid and the zinc nails,is it the same in case of other fruits with citric acid(lemon).
    Will there be any difference using lemon and orange?

    What happens is that one Zn atom loses two electrons and becomes a Zn2+ ion, which goes into solution. The two electrons reach the copper cathode here they add on to a Cu2+ ion, which becomes a Cu metal atom which deposits on the cathode. Otherwise the electrons attach themselves to two H+ ions in the solution which goes off as a hydrogen gas molecule. No current flows through the electrolyte itself. The reactions take place on the surface of the anode and cathode.

    Okay.....thank you sir.😀
    very interesting reactions.
