Data center clients
Operators and colocation providers who need dense, dependable power for AI and high-performance compute on-grid and off-grid.
Company
About 235 Electric
Radioisotope generators for the world's most demanding compute infrastructure.
235 Electric is building radioisotope generators for data centers in the 1 to 100 kW power ranges.
We combine commercial isotope supply chains with advances in thermophotovoltaic conversion to deliver quiet, always-on power where grid expansion timelines and intermittent renewables do not meet operator needs.
Mission
How can compact isotope power give data center operators baseload reliability, zero direct emissions, and predictable long-term economics without the lead time and scale of traditional nuclear plants?
Partners
Our ecosystem
Power & utility partners
Organizations that contract power solutions for data center campuses and mission-critical facilities.
Nuclear suppliers
Reactor operators and isotope producers we are engaging to secure Co-60 supply for our generator cores, with relationships grounded in safety culture and long operational horizons.
Engineering suppliers
Machine shops, fabrication partners, and engineering suppliers with aerospace-grade manufacturing and assembly capabilities to support generator production.
Science
Underlying technology
Co-60 isotope advantage
We leverage Co-60 decay rather than fission. Passive decay is simpler to manage, safer, and lacks weaponization risks. Its 5.7-year half-life aligns with standard 5-year GPU replacement cycles.
High-efficiency TPV
Thermophotovoltaic cells operate like solar cells in infrared, absorbing radiant heat directly into electrical current at 40% efficiency via specialized back-surface reflectors.
Regulatory advantage
Co-60 is regulated under industrial and medical byproduct material frameworks, unlike Uranium, Plutonium, or Strontium under special nuclear materials frameworks.
