Our Mission

We are dedicated to materializing our state of the art hybrid two-stroke engine technology. Our patent and copy written applications will revolutionize the internal combustion two stroke engine. This new engine design will operate on multiple fuels, performance levels, and will reduce pollution compared to other four stroke automobile engines. Manufacturers are currently evaluating this breakthrough technology for long term feasibility. We welcome individuals who will help to enable our goal.

Live for positive choices.
         Let's breathe cleaner air.
