What is Zeno?
Zeno is an innovative technology firm dedicated to revolutionizing power generation through the development of advanced radioisotope power systems (RPS). Unlike traditional, cumbersome power sources, Zeno's proprietary technology is engineered to be both lightweight and highly cost-effective, enabling long-term, clean energy output for decades. The company's market position is defined by its ability to serve the burgeoning space economy, where reliable, resilient power is a prerequisite for mission success, as well as terrestrial markets requiring high-density, autonomous energy solutions.
By focusing on plug-and-play modularity, Zeno is effectively lowering the barrier to entry for deep-space exploration and remote infrastructure projects. Their engineering approach addresses the historical limitations of RPS technology, positioning the firm as a vital component in the future of global and extraterrestrial energy infrastructure.
