Eric Laithwaite: RexResearch.com: New Scientist: Eric Laithwaite Defies Newton (14.Nov.1974)
The Professor of Heavy Electrical Engineering at Imperial College London, Eric Laithwaite, highly successful inventor of the linear motor, has entered the sacrosanct domain of the mechanical engineers. And he says "they need me". Last Friday as the piece de resistance of his evening discourse at the Royal Institution he demonstrated a machine that, he claimed, violated gravity and produced lift without any external reaction.
