  Sure, if your phone only needs a fraction of a watt and you’re okay with an unshielded neutron source pressed against your head.

    If the mars rovers can function on a fraction of a watt, then I don’t know why my phone can’t…

      If the mars rovers can function on a fraction of a watt,

      It doesn’t?

      Perseverance’s power system works essentially like a nuclear battery. …The power system will reliably produce about 110 watts …The MMRTG also charges two lithium-ion batteries, … Perseverance’s power demand can reach 900 watts during science activities.

        Yeah, see!

        An RTG could power my phone!

        Sigh, let me spell my point out for you…

        What I mean is that I can absolutely believe that a solid state battery could power the next gen smart watch, I doubt it will.

        Just as an RTG could power my phone, but I doubt that it will be powered by it.

        To give some perspective on this, I’ve lived for the last three months in a camper with a DC fridge. 1350 watt battery. The rtg at 110w/hr would keep my battery charged. 50 watt tv, 72 watt fridge, 24 watt starlink plus lights and waterpump. It would be just enough for me to live on I’d say.
