The Hope Solar Tower "was to stand as high as three Eiffel Towers and be surrounded by a wide skirt of glasshouse type structures. Heat from the sun would be trapped on the underside of this skirt and its only way of escape would be up the tower -- past turbines which generated the power," Warren tells us. Alas, the project has been scaled back significantly.
