[T]he mirror really is itself, for it changes hands for you as you go through the mirror and changes the motor to a generator at the same time. - Eric Laithwaite

Linear motors can be regarded... as the physical result of splitting and unrolling of rotary machines, and there are therefore at least as many types of linear motor as rotary...

I was telephoned by a man called Alexander Charles Jones, who asked me if he might bring me a box of apparatus which he said when put on frictionless casters and set in motion inside, would displace itself outside its own dimension. Immediately I knew this man was different. ...Any ordinary crank would have said, "How would you like to see Newton's Laws disobeyed." ...So I said... "Does you box contain anything that might loosely be described as a gyroscope?" ...He said, "In the box, there is a gyroscope." I said, "I think you'd better come and show it to me... because I know enough about gyros to know that they're like electromagnetism, and I've studied electromagnetism for thirty years and I know darn well I don't understand it, and I don't understand gyros either, but I can invent new things in electromagnetism once a year. And if you've got something new about gyroscopes I want to see it." And he brought it, and it did. And that was the start of a new line of research for me. And then, about a year later, I met a second enthusiast called Edwin Rickman who added his own brand of instinct that... improved the ideas we'd already got. Let me say of Alex Jones that since I first met him that I've been convinced both of the validity of his argument, and been impressed with his feel for what I'd call the elements of nature. A thing that the more learned acknowledgement of science and mathematics have seldom had, a natural feel for what goes on...

[A] world financial recession brought governments into conflict with technological innovation in linear motors in the mid 1970s. Looking back... it will seem amazing that at a time when millions of pounds worth of commercially manufactured linear motors had been sold and had proved their worth, everyone was so slow to appreciate their value in the transport scene, knowing that bigger, faster motors would have enormously superior characteristics to those used for sliding doors, traveling cranes, conveyor belt drives and the like.
