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

Audiences we serve

Data center customers

Operators and colocation providers who need dense, dependable power for AI and high-performance compute on-grid and off-grid.

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.

Stable regulation

Controlled under established industrial regulatory categories, not military constraints.

Brand

How we communicate

We emphasize safety, reliability, and compliance in public materials so customers, suppliers, and government stakeholders see a conservative, engineering-led company, not hype or hazard-warning symbolism.

Our visual language uses electron orbitals and infrastructure cues, not trefoils or toxicity iconography associated with danger in technical contexts.
