A Very Short Description


Stclairtech R&D

About us

Stclairtech R&D is a small company focused on the evolving transportation industry. Specifically focusing on propulsion systems for virtually ALL craft, land, air, sea, and space. We are creating next-generation propulsion systems that do not  require gasoline, diesel, or rocket fuel, and produce no harmful emissions.


Stclairtech R&D works independently with very modest private funding and minimal staff, even so we are constantly evolving and growing.


Our mission is to provide transportation propulsion solutions for everyone and have now successfully tested several models of "closed-loop propulsion" engine in real vehicles on public highways.

Bryan StClair


Bryan started Stclairtech R&D in the ‘90’s while researching alternative energy generating systems and alternative fuel systems for automotive applications.


After building several operational prototypes in the alternate fuel field, and giving away the tech info., he has turned to the alternate propulsion field building (in part) upon the work of Roy Thornson. This work, to date, is fully open source and available to the public via his website www.stclairtech.tech which has links to tech data as well as videos.

His current work is revolving around putting together an electric hybrid add-on system that will operate in virtually any type of vehicle and his work (at this time) remains freely accessible.
