A turbine based heat engine comprising thermally conducting engine walls enclosing working fluid travelling round a closed conduit loop. The loop comprises a plurality of constrictions comprising, in serial flow, a tapered section, a throat, and a diverging section. Each constriction is provided with a turbine 5 arranged at the throat; the turbine being coupled to an electricity generator 4. The loop further comprises a pump arranged to accelerate the fluid around the loop. In use, the working fluid receives thermal energy through the thermally conducting walls thus raising the enthalpy and pressure of the working fluid, further work is done on the working fluid by the pump, again increasing the enthalpy and pressure of the working fluid. The working fluid enters the constriction, enthalpy and pressure falling, and kinetic energy increasing as the fluid flows through the tapered section, enthalpy and pressure falling again as work is extracted by the turbine, and enthalpy and pressure increasing as the working fluid passes through the diverging section. The thermal energy received through the thermally conducting walls may originate from a molten salt nuclear reactor. |
