Benefits of Sunpower's Proprietary Technology
Sunpower free-piston machines are based on proprietary know-how and patented design features.
- Sunpower designs are simpler, longer lived, and require much less maintenance than conventional kinematic machines.
- Our machines use gas bearings, compact linear alternators or motors, and a simple mechanical configuration; they are smaller, more power dense, and more efficient than other free-piston designs.
- Sunpower engines are mechanically simpler and intrinsically less expensive to build than kinematic machines; they do not require lubrication, seals and mechanical bearings, which combine to restrict performance and limit life.
- We have unique electronic controller technology that modulates and controls our free-piston machines.
Sunpower free-piston Stirling engine technology is protected by more than 39 United States patents and over 97 related international patents. |
