"Hydro electric schemes, which use impounded water to generate electricity, are an excellent means of energy storage, " said SSE Renewables managing director Jim Smith.
These pens would bob 60 feet below the surface, kept in place with motors powered by heat exchangers that use the temperature difference between deep water and shallow water to generate electricity.
In a full-scale tokamak this heat would be tapped to boil water, which would then drive steam turbines to generate electricity.
Geothermal power plants turn hot water into steam or vapor to run a turbine and generate electricity, after which the water is injected back into the underground geothermal reservoir.
Hundreds of acres of virgin forest will be inundated with water in order to build the reservoir to power the turbines that will generate electricity.

Many U.S. states have passed legislation calling on utilities to generate specific percentages of their electricity from renewables -- wind, water, solar or others -- by a certain date.
It would hold on to water and then let it out through turbines at both high and low tides which would generate electricity.
The water heats up as it circulates and is then brought back to the surface, where the heat is extracted to generate electricity.
Water there is pumped uphill to a reservoir when electricity is cheap and then released back down through a turbine to generate electricity to sell on when it is more expensive for suppliers to buy.
Mr Simplot himself, an avowed lover of skiing, duck shooting and the great outdoors, was attacked in the 1970s for his support for new coal-fired electricity plants along the Snake river and for a scheme to generate hydro-power by diverting water from another river into a vast underground tube.
