'Diamond-age' of power generation as nuclear batteries developed

Nuclear waste is the source of energy for a new type of battery technology.

A team of physicists and chemists at the University of Bristol have grown a man made diamond which, when placed in a radioactive field, generates a small electric current.

The team are now working on ways to refine the technology and make it more cost effective.

The prototype used Nickel but subsequent versions will use graphite. Radioactive carbon-14 has a half-life of about 5,730 years.
