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

    You think thermoelectric generators are going to struggle with low temperatures?

    If there’s one thing we can practically guarantee, it’s the heat output lol

    I’m not an engineer in this space, so i’ll leave it to more knowledgeable people to poke holes in my argument.

        Voyager I and II are 48 years old running on thermoelectric generators. that’s amazing. They are winding down because the half life of plutonium means there is much less power than when new.

        I can see future probes lasting even longer with americium as a fuel source

        But introducing moving parts for a sterling engine? In space? And expect it to last like that? Seems unlikely
