Deep Space Energy is developing a new radioactive generator technology for the European space and defense industry, which will ultimately power lunar exploration. DSE's generators use radioisotopes - materials derived from nuclear waste - to generate heat through natural decay. The solution converts this heat into electrical energy, requiring five times less radioisotope fuel than thermoelectric generators currently used in space. The generator is used to back up satellite power systems, providing backup power independent of solar energy, making it critical for important military reconnaissance assets. The work is funded by government contracts and grants from the European Space Agency, NATO's DIANA program, and the Latvian government.
