> To be clear, the potato is not, in and of itself, an energy source. What the potato does is simply help conduct electricity by acting as what’s called a salt-bridge between the the two metals, allowing the electron current to move freely across the wire to create electricity. Numerous fruits rich in electrolytes like bananas and strawberries can also form this chemical reaction. They're basically nature’s version of battery acid.

That doesn't sound so exciting to me.

Isn't that a bit like saying

"The sun is not a light source, it's just very hot, which causes hydrogen to go into nuclear fusion, which releases energy in form of electromagnetic radiation"?

Or is my comparison flawed?

The energy is coming from metals rather than the potato. The potato simply links them allowing their ions to react and create an electric potential.

What it means is that the potato is just working as a media to connect two metal plate and not as a power source. Actual voltage and current is created by the metal plates corroding and melting into potato.

So it’ll be like saying “the atmosphere is not an energy source, it just blows between the sun and solar panels” without understanding what that means.

No, the potato is basically acting as a salt bath here. It would be more like thinking the empty space the sun's light travels through is the light source, not the sun.
