If indeed they are inefficient, then why are so many used in utility power generation? Sure, that's at a different size scale than an auto or light aircraft turbine, but if an IC engine were indeed more efficient than a turbine, then why are these applications not using large "diesel" engines running on natural gas, instead of gas turbines?
