Small modular nuclear reactors designed to be deployed off-grid at remote sites. SMRs are manufactured as sealed units with a fixed energy capacity, including both fuel and generator components. This means they can be quickly setup anywhere but once depleted must be returned to base for refurbishment.
Have you ever considered taming and utilizing biters like pets or Pokemon? using this mod will allow you to capture (with a chance to fail) attacking biters, to use for making power in a treadmill generator... all you need to do is recharge them with meat from questionable sources. Now you can breed biters from eggs... leave them too long and they will hatch!
A specialized heat-exchanger to further heat 165°C Steam to 500°C steam. Function otherwise like regular Heat-Exchangers. Use a less valuable resource to first heat water to 165°C seperately, ie. waste wood in regular burner-boilers, or solar-panel powered Electric-Boilers, thus saving the energy so used to heat 15°C water to 165°C steam.
