Solar Panel Technology - Gravitational Lenses
Solar Panel Technology
In just 40 minutes on a sunny day in the UK, we receive enough energy from the Sun to provide the country’s entire energy requirements for a whole year. Quentin Cooper finds out how we can make more use of the Sun. Why are solar panels currently so inefficient and how can the blackness of a moth's eye could help improve our ray catching abilities? Quentin is joined by Professor Ken Durose, Director of the Durham centre for Renewable Energy, University of Durham and Dr Darren Bagnall from the School of Electronics and Computer Science, University of Southampton.
Why do stars act like a magnifying glass in the heavens? Astronomers have just discovered two giant gas planets orbiting a star which bear a striking resemblance to Jupiter and Saturn. Quentin finds out about how are these discoveries are being made - by using predictions made by Einstein in his theory of Relativity and searching the sky for one in a million events. Quentin is joined by Professor Keith Horne, Head of Astronomy, School of Astronomy at the University of St. Andrews and Dr Nicholas Rattenbury from the Jodrell Bank Centre of Astrophysics, University of Manchester.
