What are microturbines?
Microturbines are a fairly recent innovation bringing the advantages of gas turbines to markets for smaller applications. They employ an air compressor and turbine blades on a single shaft. Some employ a recuperator to boost their efficiency and air bearings to reduce maintenance costs. Products are available ranging from 30 kW to 75 kW of capacity; this range will eventually expand to include 200 to 300 kW generators.
