The BBC and The Royal Academy of Engineering are throwing down the gauntlet to industry, schools, universities and anyone who has ever fancied themselves as an inventor or designer. Can you build a machine to beat our challenges and all the other competitors? Filmed in October, the races will be shown as a major new series on BBC2 in January 2005. Fellows of the Academy are advising on the programme.
