If it is indeed as the video claims, "6 times lighter than air" (1/6 the specific weight of air??), how can it stay at the bottom of the petri dish when exposed to air? Shouldn't the little cube be floating up like helium balloons?
Something must have been lost in translation.
BTW, I thought the fundamental problem with battery is the weight of the reactant chemicals themselves (and the need to carry the reaction result back home for re-charging), not the substrate onto which they are impregnated.
