Is Steve Durnin's D-Drive the holy grail of infinitely variable transmissions?

Try your hand at understanding how the D-Drive works. Steve Durnin's ingenious new gearbox design is infinitely variable - that is, with your motor running at a constant speed, the D-Drive transmission can smoothly transition from top gear all the way through neutral and into reverse. It doesn't need a clutch, it doesn't use any friction drive components, and the power is always transmitted through strong, reliable gear teeth.

The story is too old to be commented.

To take a technology that's a hundred years old and to completely rethink it takes some intellect.

Not much of that these days huh....most ppl just improve on what has already been done.

Nothing wrong with taking the path of least resistance but this is impressive. Simpler, more efficient and built with existing tech. This guy just approached the problem in a different way.

talking about gears and such i have always wanted to make a magnet drive free energy machine and use to to power things.
