This book is a valuable and unique addition to the power generation literature. The author has decades of experience in the gas turbine industry, and he trained under the father of closed-cycle gas turbines, Dr. Curt Keller of Escher-Wyss in Zurich. Closed-cycle turbines experienced a resurgence of interest in the 1980s and remain a promising technology going forward in the 21st century. There is currently no comparable book available that covers both the history and future potential applications of closed-cycle gas turbines. This book is intended for design engineers and engineering managers in the worldwide gas turbine/power generation industry.
