      I reckon you probably can – although I’m no expert. 🙂

      Hi bradley,

      The two limits are power and energy. Power is how much energy you put into the engine at once. You would have noticed that some batteries are specially for “digital devices” … this is because normal batteries don’t give out their energy quickly enough, and the ones that do are more expensive. Energy is how much total “fuel” you have in your batteries before they run out. To make a fully electric fast car it would be a big sports car, with one seat and most of the rest of the space (including the boot) taken up with batteries.

      These aren’t limits in theory, it’s just that our batteries aren’t good enough at the moment.
