The solution involves fitting a nuclear power generator on planetary outposts to power a stirling engine. The reason why a stirling engine is suitable is because it is highly efficient, a closed system meaning the gas is reused for the life of the engine, and it can work with just about any heat source. The final unit is expected to be the same size as a typical suitcase and is capable of providing 40 kilowatts of electrical energy for eight years.
