Problem
Space missions, lunar habitats, and other extreme environments often lack reliable, long‑duration power sources, forcing reliance on solar panels that are limited by darkness, dust, and harsh conditions. This power gap hampers scientific operations, infrastructure development, and commercial activities beyond Earth.
Solution
Perpetual Atomics develops compact radioisotope power solutions that generate continuous electricity in harsh, low‑light environments. By converting the heat from long‑lived isotopes into electricity through thermoelectric or advanced solid‑state converters, the company provides a maintenance‑free, high‑energy‑density source that operates for years without sunlight. The technology is designed for modular integration, allowing customers to scale power output to match mission or site requirements. Safety‑focused engineering and compliance with nuclear regulations ensure that the systems can be deployed on spacecraft, lunar bases, and remote terrestrial installations while meeting stringent environmental standards.
Target Audience
Primary customers are space agencies, lunar infrastructure developers, and operators of remote terrestrial sites (e.g., Arctic research stations, off‑grid mining operations) that require reliable, long‑life power in environments where solar energy is insufficient.
