Professor Graeme Maidment explores the earliest methods of surviving a hot climate. Does ancient Egypt hold the key to an urgent modern need for sustainable cooling?

He goes to an unlikely place to find out - the Bluewater shopping centre just off the M25 in Kent.

Five scientists look back to their ancient forebears and examine how much of that early knowledge still stands the test of time.
