Parabolic troughs use large troughs to track and focus sunlight onto a pipe and the sunlight heats a synthetic oil, leading to the heating of water for creating steam. Solar power towers use a central receiver to receive and focus sunlight from a field of mirrors, while dish/engine systems use parabolic dishes to focus sunlight onto a receiver at the dish's focal point.
