Zeno Power Systems, founded in 2018, is a leading developer of commercial Radioisotope Power Systems (RPSs) that convert heat from recycled nuclear waste into electricity. These "nuclear batteries" provide reliable, carbon-free power for decades in extreme environments, from deep sea to deep space, enabling persistent operations. Zeno partners with organizations like NASA, the U.S. Space Force, the U.S. Navy, Westinghouse and ispace-U.S., with the goal of delivering its first RPS to customers by 2026. Key words: radioisotope power, nuclear battery, space power, lunar missions, deep sea exploration.
