It is a battery! He is getting some low voltage (and almost no currant) because of two dis-similar metals (nail and pipe) and an electrolyte (tree sap/ground water). He hammers an Aluminum Nail into a tree, and a Copper Pipe into the ground near the tree - hooks up some wires - and voila, he has a battery. The corroding of his anode (nail) is what is generating the low voltage.
Think it is a coincidence that you get 1.8v out of potato with some coins stuck in it?

Quite the scam.
