Bladon Jets, SR Drives and Jaguar Land Rover Win Funding for Gas Turbine Electric Vehicle Project

Green Car Congress

Oil-less carbon-air bearing system. Bladon suggests that in an hybrid vehicle application, with no water-cooling system, oil or catalytic converter, the Micro-Jet engine can provide vehicle weight savings of up to 15%—with a consequent reduction in fuel consumption and carbon emissions—compared to a piston engine.
