At the cathode, the protons and the electrons react with oxygen from the air to make water which, to the joy of environmentalists, is the only waste product of such a cell.

ECONOMIST: The dawn of micropower

Early research involved a colleague lying in a deckchair in the night-time open air with a piece of string to measure the meteors, while he observed electromagnetic signals on a cathode-ray tube in a nearby hut.
