"Combined cycles are currently used in some power stations. They consist of both a gas turbine and a steam turbine hooked up to electrical generators. By using the exhaust gas from the gas turbine to heat the water in the steam turbine extra power can be scavenged. This can increase the efficiency from about 35% to about 60%."
I got this little gem from an article on Jet Engine Efficiency, priceless.
