I know what nano-diamond batteries are - they are powered by the radiation from nuclear power plants. THAT is a primary energy source, which is why it is used to run reactors. I indicated that *could* be feasible.
Management said it would be 'recharging while running'. NDB's aren't ever recharged - they take thousands of years to run down. None of us will be alive when the first NDB runs down.
The carbon used in a nuclear reactor becomes irradiated. That carbon material is squeezed into diamond. Now you have man-made diamond that radiates energy. You harness that energy into a battery, while preventing radiation from escaping from said battery.
It is still theoretical. There is not one working example to be seen. It certainly isn't ready to power cars - but it would be good in cell phones, which now get thrown away because the batteries are not replaceable.
