Under the agreement with DOE, Zeno will have access to a large supply of strontium-90, a radioisotope created as a byproduct in nuclear fission reactors. The company will use the material to build radioisotope power sources, or RPS systems. These are compact devices that convert heat from isotopes into electricity. NASA for decades has used RPS systems for deep-space missions, but these systems are fueled by plutonium-238, an isotope that is in limited supply. Zeno designed an RPS system for small satellites fueled by strontium-90.
Pretty neat that nuclear waste could be recycled into something useful.
So Musky is going to start using these in his shitty satellites that are dropping out the sky like flies and next thing it’s raining nuclear waste?
Can’t wait
Highly unlikely. These RPS systems are best suited for military GEO satellites and lunar missions, not civilian LEO satellite constellations like Starlink. The article has more details and links if you are genuinely interested.
