I don’t know if anyone carries a pocket calculator anymore (most cell phones should have one, really), but they were all the rage back in the eighties when they figured out how to make them smaller and cheaper. Most of them became solar at that point, but there was nothing like the Water Powered Calculator. As its name suggests, the Water Powered Calculator uses water or any other type of electrolytic liquid for power. I am assuming that Gatorade would probably work just as well. Anyway, the liquid creates a chemical reaction in the fuel cell with a zinc anode and cathode. This somehow makes an electrical current that is good for a month’s worth of power.
