Capstone Hybrid Vehicle Microturbine Close Up

A truly remarkable piece of turbo-machinery the Capstone is a mile stone in world gas turbine and microturbine development. No other engine have every been built like it, the C30 belongs to a three model range that all adopt the same innovative construction and layout. An economic and long life microturbine is a significant technical challenge and the C30 comes closest to for-filling this goal but remains an expensive machine double the costs of a reciprocating equivalent.
