Perpetua Power Source Technologies

Perpetua Power Source Technologies is a clean energy company that develops thermoelectric energy harvesting technology, converting heat from widely available sources into useful electric energy for powering small electronic devices. The company Power Puck devices utilize thermoelectric thin-film technology to convert temperature differences into electricity, enabling autonomous power for wireless sensors, IoT devices, and industrial monitoring equipment without battery replacement or wired power connections. The technology is particularly valuable for applications in remote or difficult-to-reach locations where conventional power sources are impractical. Perpetua solutions serve facility management, industrial monitoring, and building automation markets, providing long-lived, maintenance-free power generation. Founded in 2005 and headquartered in Corvallis, Oregon, the company has raised approximately $8.6 million through Series B funding from investors including NextSteps Capital, the National Science Foundation, E8, and ONAMI.
