We are a young, dynamic start-up company that was founded in 2014. As a “hotbed of technology”, we possess the technical know-how and the unbridled passion to drive forward the development of the FreeP and to prepare it for series development.

But will the FreeP also be able to establish itself on the market?

We are convinced, because it is revolutionising existing technologies and meeting demands for both e-mobility and clean energy.

A development partnership with the DLR drew our attention to the free piston linear generator project. This gave rise to the idea of our company. We are enabling the further development of the engine to be driven forward, and are cultivating the utilisation of the relevant know-how and laws.

All just crazy ideas?

The proof-of-concept in February 2013 made it clear for the first time: the system works! Our task now is to further develop the key technologies so that a prototype can be completed in three years.

We Are SWEngin

“We firmly believe that the FreeP represents the missing piece of the puzzle in terms of both vehicle propulsion and energy supply, that it will for the first time unify the fields of e-mobility and clean energy, and in so doing will provide an integrated concept for solving the global energy problem.”
