Capstone Turbine Corporation (NASDAQ: CPST), announced that it has received a 150 unit order for C30 Capstone MicroTurbines(R) to be deployed in ECOSaver IV hybrid electric buses manufactured by DesignLine International. This is the largest order to date for Capstone products in a Hybrid Electric Vehicle (HEV) application.
Hybrid electric buses equipped with Capstone microturbines, have been operating in various parts of the world for approximately 10 years. DesignLine buses are constructed with advanced extruded aluminum technology making them lightweight and very strong. The end result is the most fuel efficient vehicle available. In recent product demonstrations the ECOSaver IV hybrid buses equipped capstone turbines have seen up to a 100% improvement in fuel economy over a traditional diesel bus which equates to fuel savings of up to 6,000 gallons per year according to DesignLine.
The bus has a serial drive, running on batteries all the time, the turbine being only used to charge the batteries The buses are also equipped with regenerative braking. In urban driving the buses get about seven miles per gallon. The buses were tested by the New York Metropolitan Transportation Authority for two month beginning in October 2007.
Standard nominal specification are: Top speed: 62 mph, Max gradient: 15%, Max Power: 250 KW, Max Torque: 2500 NM which may change depending on configuration selected.
