    3V at 100 microwatts significantly limits its usefulness.

    They say they’re planning to make a 1W version, which I assume will be either be much larger or have a much shorter lifespan. How does it work? Does it have a way to stop the reaction or does the 1W battery generate 1W of heat when there’s no load attached?
