 Starship Heat Engine with Black Body Cooling
52 KB GIF

 One concept being advanced for long distance space travel is ION propulsion using a nuclear reactor as an energy source.  The knob at right sets the power going near ideal Carnot heat engine ( set at 96%).  That is 96% of the thermal energy available in system is converted to mechanical energy.  An old fashioned steam engine got about 10% efficiency.  I've decided that with a little help from the Vulcans 96% will be attainable. The center gauge indicates temperature of "boiler" and the lower right gage indicates temperature of condenser/radiator that must cool itself by black body radiation. The top right gage indicates the power output.  

 

Notes: nc = Carnot efficiency; n = actual efficiency. Output valve 1 on boiler is closed at temperature below 400 degrees Kelvin. Output Valve 2 starts opening at temperatures of 1123 and goes to full open at 1127. Valve 2 regulates maximum Boiler or Qh temperature at 1125.
