Formerly in Aerospace/Defence propulsion area, I made a transition to energy/environment in 1995 to work on renewable energy. Specifically, biomass thermochemical processing into standard drop-in transportation fuels, like high-octane gasoline. I have founded Transmediair, Inc (later renamed Primus Green Energy, Inc) in New Jersey. I am the architect of Primus' proprietary technology, specifically, catalytic biomass gasification and other patents, including a modified version of the Mobil (1972) methanol to gasoline or MTG process. I am currently the President of Verdant Aerospace, LLC, developing technologies for renewable fuels, advanced micro turbines, and non-fracking shale-gas extraction. I have a BSc from the Technion, Haifa, and a PhD from Princeton University, both in aerospace and mechanical engineering.
