Project Sunshine reveals for the first time how cutting-edge science can use the sun - and other renewable energy sources to return us to a 'solar economy' - to provide sustainable food and energy for a global population of 9 billion people, eliminating the need for 'fossilized sunshine' in the form of coal, oil and gas. Professor Tony Ryan is the leader of 'Project Sunshine', a far-reaching project at the University of Sheffield that brings scientists together to find solutions to the world' s problems. From photovoltaics to organic electronics, from microbial science to optoelectronics, the power of the sun is central to this new, holistic approach. Capturing just one hou' s worth of sunlight will enable us to meet the plane' s food and energy needs for an entire year. Written with PR guru Steve McKevitt, and unmissable for all popular science and history of science fans, Project Sunshine gives us a true picture of how we are going to live - and going to have to live - in the surprisingly near future. Professor Tony Ryan OBE is a polymer chemist at the University of Sheffield. He delivered the 2002 Royal Institution Christmas Lectures and regularly appears on Radio 4's Infinite Monkey Cage with Brian Cox and Robin Ince, and has been on In Our Time with Melvyn Bragg.
