That's also a bit of dodgy science, which is actually propagated in
otherwise reputable places. Most of the energy actually comes from the
bits of metal that are inserted into the lemon, not from the lemon
juice. Those electrodes are destroyed in the production of energy.


Nobody claims that the energy comes from the lemon juice as opposed to
the whole system including the electrodes as with all batteries.

Quite. One electrode is sacrificial but the other one isn't, thanks to
the current carrying capabilities of the lemon.

So is some of the acid in the lemon.

If you want to add a bit more zest to the programme, you could include any
bells of London churches - Oranges and Lemons.
