DARPA and NASA have some combined projects developing small reactors suitable for both mars and deep space exploration as well as replacing oil tanks for generators in remote military installations like in the arctic. This is almost certainly chasing that, not consumer generation.
- ripe 4y agoFrom Robots In Plain English [1]: The Curiosity and Perseverance rovers each carry an old kind of power supply: a nuclear power generator that runs on radioactive plutonium dioxide. This generator has been used on many missions since the 1960s. It produces a steady 110 watts of electricity. The decay of the radioactive material also emits heat, which helps keep the electronics onboard warm through the freezing nights on Mars. Supplemented by rechargeable batteries, the generator provides enough power to let the rover pull all-nighters for years to come.

- jasonwatkinspdx 4y agoI know what a RTG is. I'm talking about this, a different topic entirely, as RTGs cannot practically meet these requirements: https://www.thedrive.com/the-war-zone/26152/the-u-s-military-wants-tiny-road-mobile-nuclear-reactors-that-can-fit-in-a-c-17 https://www.thedrive.com/the-war-zone/26152/the-u-s-military...

- midoridensha 4y agoRTGs are horrifically inefficient sources of power. They work well enough for providing a paltry 110W to a rover on another planet, but that's not going to scale up to providing power for millions of people. The amount of plutonium you'd need would be astronomical.
