Examples futuristic - include minute pump that can fit inside human tissue and a huge test rig to help develop high speed vehicles driven by a linear motor. This is one of a series of 16mm colour films made for schools. They were all made in Eric Laithwaite's "Heavy Electrical Laboratory" in the Electrical Engineering Department at Imperial College London.
