Powering what comes next.
Multi-fuel electric power generator
At Theta Motoren, we have developed an innovative engine-generator: an Arcual opposed-piston engine combined with an axial generator. This disruptive design opens new opportunities in decentralized power generation and backup systems for remote locations.
Rethinking the Generator
Theta Motoren has developed a fundamentally new engine-generator architecture that integrates an arcuate-motion opposed-piston engine with an electric generator. The result is a lighter, more compact system with fewer components and higher efficiency — capable of operating on multiple fuels, including hydrogen and diesel.
Founded by inventor and CEO Shaul Yaakoby, Theta Motoren builds on decades of engine innovation and prior experience in scaling advanced propulsion technologies. The company is moving from validated design into prototype development and initial pilot deployments, supported by a growing IP portfolio.
The system is designed to meet specific customer requirements and scales from a 20 kW base output to higher-power configurations for industrial and civil applications.
