It is good that a estimated 60-70% of the energy will be converted into electricity, that much better then power plants limited to carnot cycles (~50% at best), but still that 30-40% of heat, how will a DPF fusion reactor be cooled? Could it run a steam/stirling carnot cycle on the waste heat to produce even more electricity? What would be the coolant (air or water?) and would it be closed or open cycle?
