- A Generator that uses Linear Motion rather than Rotary Motion
- It requires more complex electronics, but may be more efficient in some applications, especially where electricity production is preferred, not rotary motion (ie not a vehicle's Traction Motor etc)
- Also it allows for a more compact and/or simplistic design in some cases (No need for Camshafts / Crankshafts etc )
- Also if done in the form of an Internal Combustion Engine it can even be tuned more via software than hardware
Industry Standards / Existing Work
- It doesn't seem to be too common of a technology as of now, although it may be finally emerging?

- A Video by the YouTube Channel "Mainspring Energy" Titled "Mainspring Linear Generator"
- Bit of Greenwashing in that they say it is fuel flexible and runs on biofuels, however on the Specifications Page it says "Natural Gas or Biogas w/up to 30% H2 Blend 8-25 psig Inlet Pressure No Water" (So essentially CNG or H-CNG are the ONLY fuel options
University of Edinburgh

Sir Joseph Swan Centre for Energy Research / Newcastle University
- A Video by the YouTube Channel "Sir Joseph Swan Centre for Energy Research" Titled "Free-piston Engine Range Extender Technology"
- Information seems hard to "pin down" ?
- This may be the same project? This is the Durham Energy Institute video on the topic with very similar visuals / information?
- Currently they produce "intelliGEN: A developer platform for opposed Free Piston Engines"

Sandia National Laboratories
- "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."
