The Royal Institution Annual Christmas Lectures to Young People
The history of man's use of solar energy has been the slow story of a species groping towards a way of doing what green leaves have been doing effortlessly all along-making chemical fuel from sun-beams.
Sir George Porter concludes his series of Christmas lectures by suggesting a new direction for research. As well as better solar panels, why not better imitations of the leaf? He invites his young audience to look forward to a future when man can make not only electricity but chemical fuels, too, direct from solar energy.
