Sad, but not one word about energy density, power density, voltage, current,
charge rate, discharge rate, lifetime or any other useful parameter that
could give an indication of the usefulness or viability of this device.
Because of the glaring lack of useful information, are we to conclude that
this is just more smoke and mirrors and energy BS like so much else we keep
hearing about? It seems that when real advances are developed, people go to
great lengths to explain what is better about it and how it can replace
existing technology. The lack of information says volumes about this
"advance."

Furthermore, they claim it to be environmenatlly benign and not contain
toxic materials. Yet the use of carbon nano-tubes in these "batteries" may
turn out to be worse than asbestos as a health risk. They are a bit quick to
claim environmental friendliness.
