Basics
- A Piston Engine where the engine is "free" within the cylinder; it is not connected to a Crankshaft
- Can be used as Gas Generators and/or Linear Generators
- If the coils of the linear generator are also used as a Linear Motor this can be used to control the position / motion of the piston thus allowing for software tunable, infinitely variable compression ratios etc
- Also Part Reduction occurs etc
- Main issue is in the difficulty in control, as well as Noise and Vibration / Noise, Vibration, and Harshness

Sandia National Laboratory led by Sandia researcher Peter Van Blarigan that has been testing physical components of free-piston engines which could be 50% efficient. This is about twice as good as current combustion engines and about as efficient as fuel cells. Fuel cells are too expensive. He is assembling a complete free-piston engine prototype, a project that he expects to complete within a year.
