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.

Michael Charlton and Charles Wheeler present news and opinion. Including every Friday Westminster Report presented by David Holmes Newsreader Angela Rippon

A Smile for the Crocodile
The crocodile is the world's largest living reptile and has a reputation for being the most dangerous. It is true certain species eat people, but now research is revealing the crocodile in a fresh light. It can slow its body functions to the point where the heart beats only four times a minute. It spends much time caring for its young, and recently the mother crocodile was observed to carry her young in her jaws.
Today, apart from the American alligator, all species of crocodile are in danger of extinction. If they are not shot for their hides, their habitat is destroyed for agricultural use. What are the chances of survival for this remarkable animal?
