Tomorrow's World

A retrospective of the 1970s, including the changes in technology, changes that were expected and didn't happen, and how the programme itself has changed.

As 'Tomorrow's World' goes off the air for a summer break, the series concludes with a timely look back at some items from the past year. Michael Rodd simplifies solar physics and studies otters in a California zoo, while Kieran Prendiville road-tests a new timber tractor. Judith Hann demonstrates a phone-operated heart monitor and scales new heights with a DIY lift, and Prendiville returns to bash out a tune on a new synthesiser that can sample real sounds.
