waste heat - sswelm/KSP-Interstellar-Extended GitHub Wiki
Waste Heat is generated by inefficient conversion of one type of power source to another. Consider the use of a Molten Salt Reactor, which produces Thermal Heat (not Megajoules, or Electric Charge). A [[Thermal Electric Generator] is used to convert the Thermal Heat to Megajoules, however, that conversion rate is not 100%, and results in heat that is not very useful.
Waste Heat can be managed by Radiators to disperse them.
