    Re: Something from nothing

    Here's a new practical energy producing product from what was previously "nothing":

    A salt water powered lantern. -with USB port!

    What is the potential for increasing the scale?

      A magnesium rod (which is consumed in the process, along presumably with some ions from the salt water) is far from nothing. Will the replacement rod cost more or less than a CR123 battery which can give a considerable amount of light for 120 hours without the need to carry around salt water?

        The ad says "no battery" but it has a magnesium rod, a carbon rod, and an electrolyte. What is that? A battery.

          Could be a legal problem using that device you may be charged with asalt and battery. ?
