Media Release: Caging the ‘heat of the sun’ with diamond

A GROUP of Scottish scientists will be playing a vital role in an international
project working to develop waste-free nuclear power, providing energy without
contributing to global warming.

Their role is to contain the heat of a potential nuclear fusion reaction, comparable to the sort of temperatures found in the sun, by coating the inner walls of the reactor with home-grown diamond.

The Diamond Research Group at Heriot-Watt University has developed a unique method
of growing diamond film at relatively low pressure and temperature, using gases to
lay down the material in a plasma.

The group is led by Professor Phil John and
Professor John Wilson.

Professor John said: “The ultimate energy source is the Sun.
Confining the fusion power of the sun on earth has long been the goal of scientists
and engineers searching for a benign source of energy which does not pollute the
planet with long lived radioactive waste or contribute to global warming.”
