Ultimate Trough Testloop, Harper Lake, California, USA

The Ultimate Trough is the largest and arguably the most cost-efficient parabolic trough collector in the world. Electricity generation costs are minimized by the combination of improved structure - employing for the first time automotive joining technologies - and better optical and aerodynamic properties. Gerhard Weinrebe explains the engineering drive and technology behind the Ultimate Trough. For more information on this project please visit: www.moveables.sbp.de
