The result is an ultracapacitor, a battery-like device that stores and releases energy quickly.

There is the rub. No matter how many wafers of super conducting and ultra dielectric material used I don't see how they can slow down the discharge to the ten or so hours they claim. As Dr. Perry suggested, it would "trickle" drain on its own before the power can be delivered as intended. I would not put money on this one.

For twenty five years we have been told that the home fuel cell was also just around the corner.
