The microturbine is a power generation system that is based on a combination of a small gas turbine and a directly driven high-speed generator. In many cases, the gas turbine includes an exhaust gas recuperator that improves the efficiency of the system.

The design of Turbec's gas turbine is very simple and the pressure ratio is low. The turbo machinery design can be compared to that of a turbo charger used in piston engines. The high-speed generator is on the same shaft as the compressor and the turbine. No gearbox is needed and the system uses only two bearings.

The electricity created by the high-speed generator is converted into useful voltage and frequency by a power converter that is also part of the system.

The microturbine uses a combustor that can run on various fuels such as natural gas, diesel, ethanol, and biogas. The level of harmful emissions is very low.

Inspired by developments in the automotive industry, the ingenious design of the microturbine is the key to its reliability and competitive price.
