1.   The process of transforming the plutonium creates tremendous quantities of heat, Bowman noted, and that heat in turn could be used to spin turbines and produce electricity.

2.   The steam spins turbines that create electric power.

3.   The system would burn gas or oil to spin a turbine to generate electricity.

4.   The turbines were deliberately spun down Thursday until the component could be fixed.

5.   Waste heat from the process could spin turbines and produce electricity.

6.   Geothermal plants tap into that pressure and use it to spin turbines.

7.   Steam from the earth is piped to the power plant, where it spins turbines to create electricity.
