Prime Lightworks was founded in 2015 by Kyle Flanagan to investigate measurements of impulsive thrust from a closed radio frequency (RF) cavity in vacuum. We remain hard at work developing superconducting RF resonant cavity thruster technology for CubeSat propulsion, while recognizing the long-term nature of this endeavor, and keeping aim on revenue and company profitability. For these reasons, we are expanding our technology portfolio for renewable space propulsion to include green hydrogen rocket engine development for reusable launch vehicles.
