“The isotope of interest for space is americium-241…Its half-life is a staggering 432 years, five times longer than plutonium-238.”

My understanding of space engineering is that getting rid of heat is a bigger problem. Makes me wonder how much of efficiency of Stirling engines are lost due to extra weight and complexity for heat exchangers and radiators.
