since batteries are around 1mj/kg making them 43x heavier than say kerosene, would it be possible to electrically charge (and actually hold said charge) within an alternative ultra-lightweight (conductive) material or fluid? what do you think said material / fluid would be?
also what do you think would be the lightest substance cheaper or around the price of aluminium possible to build a plane with?
