KSPIE - What am I supposed to do with ThermalPower?

[Frostiken]

I have four nuclear engines and they keep accumulating ThermalPower. Once it saturates, the engines become worthless and won't work. Warping for some time did nothing to sink it. In fact I think it went up.

I'm not talking about Waste Heat, my four ginormous radiators handle that.

thermal power is basically a resource from what I know, you can use it up by attaching a generator to the top or another engine to the bottom (such as a thermal rocket nozzle) to the reactor/nuclear engine (there are nuclear engines that can have their thruster replaced by a thermal/plasma/magnetic nozzle). Thermoelectric generators use Thermalpower to generate ElectricCharge
