Thursday The Material World. As reported in NCE on 11 October, the world's largest solar hydrogen energy project, designed to power pollution free buses, is to be built at Cambridge University. The plan is to use sunlight to create hydrogen from water to power buses which will emit nothing more harmful than a trickle of water. Well how about that? Foresight, you will be pleased to know, is powered entirely by hot air.
BBC Radio 4, 4.30pm Friday Science Shack. This week Adam Hart Davis looks at why the Millennium Bridge wobbled. He and the team construct an experiment to show how the effect could have been foreseen and how the defect was most likely caused by synchronised human behaviour.

Discovery Wings, 8pm Monday Garden Railway. Building a model railway in your back garden presents more of a civil engineering problem than a modelling one, as presenter Mark Found considers the survey and design of a grown up's choo choo set. At the same time, on the same channel tomorrow, a look at water features and uses for an old bilge pump. It's not all romance and nostalgia in the railway garden, you know.
Discovery Channel, 2.30pm Judge John Deed.
John Barber wrote to Foresight to say this programme deserves a mention because of its relevance to the ICE. You'll have to take John's word for it and I'm afraid it's the last of three episodes tonight.
No jokes about hindsight please.
BBC1, 8.30pm Wednesday Century in Motion. A tour of Los Angeles, Hanoi and Berlin looks at how transport develops differently to suit specific cultures. The roads of Hanoi on a moped or cruising along the LA highways - take your pick.
