From the wonderful Huffington Post is this article about an 'electrifying' (pardon the pun) new discovery! Scientists at The University of Washington have discovered that trees may be a new source of electricity! Here's more from the article:
"...In an experiment that will seem familiar to students of the potato, the scientists stuck one electrode into a bigleaf maple, and another in the ground, and saw that the tree generated a tiny stream of electricity -- a few hundred millivolts. That's not enough electricity to do much ... but run a circuit and get published in the scientific journal Institute of Electrical and Electronics Engineers' Transactions on Nanotechnology.

(As of that potato, this experiment is different, the authors said: "The tree-power phenomenon is different from the popular potato or lemon experiment, in which two different metals react with the food to create an electric potential difference that causes a current to flow." The tree experiment uses the same metal for both electrodes.)"
