The Boeing SUGAR Volt
Boeing has pulled the sheets off of their Subsonic Ultra Green Aircraft Research (SUGAR) Volt concept, this unique aircraft has an electric battery gas turbine hybrid propulsion system. The SUGAR Volt is theoretically capable of travelling at the same speed as current generation passenger jets whilst using 55% less fuel. The wings have been designed to fold flush against the fuselage to save space whilst on the ground, busy airports are becoming more and more of a problem as the number of jets being serviced continues to climb each year. The Volt will be able to run on either electric (battery) power or its gas turbines and will be capable of carrying 135 people as far as 3,500 miles.
