Portable Small Engine

The CalSEED Concept Award has provided a critical piece of funding we've needed to produce fully functional prototypes of our zero-emission mobile power system designed to replace the small gas engines found in commercial landscape maintenance equipment. As well, CalSEED, in coordination with the CleanTech Open, has been instrumental in the development and refinement of our business plan. As both a grant subawardee and California Ratepayers, we could not be any more appreciative of the CEC's CalSEED program.
