Description

Inside Science is a secondary science series following the success of Scientific Eye and Science in Focus. Inside Science explores several technologies and concepts which are attempting to use the sun to meet the world's energy needs.We talk to a physicist about cutting-edge solar voltaics, we meet an advocate of the Desertec plan to use the world's deserts as a land base for solar energy plants and electricity production, and we visit one of the world 's most advanced concentrated solar energy power plants near Seville, Spain. This solar tower plant, which has a cathedral of light appearance, may be providing all of Seville's electricity needs in the years ahead. An engineer at the plant explains how ancient concepts and modern technologies combine to pave the way for endlessly renewable energy from the sun. A think-tank adviser to governments and business explains financial and political obstacles confronting renewable energy today - and how to overcome them.
