Welcome to RotaPower LLC

To produce engines so powerful, compact, and emission free that they become the preeminent choice for ground, sea, and air applications

Based upon the ingenious design of German engineer Felix Wankel, RotaPower LLC has the exclusive rights for developing & manufacturing the Rotapower® engine. With over 40 years of research in this technology, RotaPower LLC can now produce engines without many of the disadvantages historically attributed to rotary engines.

We here at RotaPower LLC realize that the promise of this technology offers considerable advantages over traditional piston engines in many applications, and we welcome the opportunity to prove this to the world.

Our Featured Rotapower® Applications

Biogas Generation

The Rotapower® engine is ideal for converting contaminated biogas into electricity. It's resistance to hydrogen sulfide and siloxane reduces overall operational and maintenance costs in CHP systems.

Renewable Energy

A Rotapower® generator can provide dispatchable power for microgirds and renewable energy production. Using carbon neutral fuels, this is low cost and environmentally friendly alternative to industrial battery systems.

Range Extender

Electric vehicle market penetration has been limited by range anxiety of consumers. A Rotapower® range extender can overcome this barrier, and because of its small volume and high power density, it will not impact vehicle design constraints.

Advanced Air Mobility (AAM) VTOL Aircraft

AAM VTOL aircraft can significantly benefit from the high power to weight ratio and small volume, providing far more longevity and safety compared with battery-based propulsion systems.

Marine Craft

Improved emissions, small volume and high power make the Rotapower® engine a excellent alternative powerplant for personal watercraft.

Powered Cycles

Small engines with low emissions and high performance over competing engines make the Rotapower® a ideal powerplant for small 2-wheeled vehicles.

Small Generators & Mobile EV Chargers

Because of the Rotapower® engine's small size and high power density, small portable generators become more practical for widespread use in urban and rural communities worldwide.
