Capstone Turbine Corporation (NASDAQ: CPST), incorporated in 1988, is a California based gas turbine manufacturer that specializes in microturbine power and heat cogeneration systems. Key to the Capstone design is its use of foil bearings, which provides maintenance and fluid-free operation for the lifetime of the turbine and reduces the system to a single moving part. This also eliminates the need for any cooling or other secondary systems.
