Technology & product

Radioisotope generators for data center power, from single modules to multi-engine systems.

Architecture

How it works

At the core of each generator is a Co-60 capsule, a commercially available, high energy-density heat source in standard format. We leverage its abundance and established supply chain as the fuel that drives our modules, converting decay heat to electricity through thermophotovoltaic (TPV) cells.

Passive isotope decay is simpler to manage than fission, with no moving parts in the generation path. Modules deliver continuous baseload power adjacent to or outside the data hall without grid-only or intermittent renewable constraints.

Co-60 at the core of our generator

Co-60 is the fuel inside our generators, a commercially available, high-density heat source that powers every module we deploy.

Note: We are not selling isotope capsules as a standalone product.

Product advantages

High efficiency

Up to 40% TPV conversion with state-of-the-art BSR (back surface reflector) photon recovery.

No moving parts

Semiconductor generation with no turbines, steam cycles, or mechanical failure modes.

28+ year life

28+ years of operational life aligned with the Co-60 isotope half-life cycle for predictable long-term output planning.

Modular scale

Engines deploy side by side with standard electrical interfaces and no custom plant build.

Integrated cooling

Outdoor placement at 85°C surface temperature without added data hall cooling.

Silent & clean

0 dB at generation, 0 g CO₂/kWh on site, with no fuel trucks or combustion exhaust.

Benchmarks

Comparison with alternatives

Our isotopic generators outperform alternatives on over 90% of metrics on-grid and 100% of metrics off-grid.
