The “holy grail”: a lightweight ultracapacitor, a few cubic feet in size, able to run an electric car several hundred miles and recharge in a few minutes.

One problem with ultracapacitors: propensity to instant discharge if possible. Safety is a huge issue when capable of dumping 100kW/h thru someone in a millisecond.

capable of dumping 100kW/h thru someone in a millisecond.

That's getting the short end of the stick. Resistance would be futile.

And yes, I've got no shortage of horrible puns. I should be grounded for it.
