Earth's living beings and over-active little boys already run on it. Sugar batteries or enzymatic (neither explosive or flammable) battery fuel cell, maltodextrin is combined with air, water and electricity are produced! The synthetic enzymatic pathway is stripped of all the sugar's potential charge, thereby generating electricity and its only byproduct is water. The sugar battery has more energy density than most other batteries and the most environmentally friendly way to produce a transportable energy source.
