Secrets of the Universe: Power vs. Energy

I love me a good analogy, and though I have power and energy pretty straight in my mind, I’m reading “Bottled Lightning” right now (which is awesome and you should read it) and about halfway through he compares the power and energy thing to a bottle of water.  Energy is how much water is in the bottle.  Power is how fast you can pour it.

Perfect, right?

That is all.

  1. And that’s why at some point we will have hard time to fill-up the “bottle” as battery capacity will increase. If one day we can achieve the same range as an ICE vehicle then it will take ages from your normal outlet.
    From a charging-station that would mean some crazy big cables if the charge must be fast, a lot of energy to move in a short time.
