Ricks Pipe Dream

[nyctuber]

Don't see how it could work, the spring force required to keep the stator arm in the first position will negate rotation when the lever hits the aluminum bar. Rick seems to think the flywheel effect is an important factor, but have you seen what happens when neo magnets (any magnets, really) interact with each other? The wheel can seem to have momentum, yet will stop on a dime.

That very statement seems to Imply potential being wasted by bad design

If one magnet can bring a rail or rotor[with many magnets] traveling at speed to a sudden Stop [which we all have seen]

Seems like a design issue [an understatement]

I believe you're referring to an eddy brake. That's used on systems which actually generate torque. Rick's setup is getting all of it's input energy from manual movement of the arm. The spring and lever will cancel out the spin.

The tracking mechanism is obviously going to make sure the stator will never find itself in a position where the forces of the magnets result in anything but a desired effect.
An immediate stop of a quickly fast moving mass, by permanate magnet force (moving along each other zero psysical friction) alone, would be quite the invention. The railway companies would want to know about it, as would the military.

In video #16 it does seem that for the first few revolutions where Rick manages to get the timing right, he does indeed with very little effort get the wheel to spin up nicely. That said, a mountainbike with a climbing gear would also see you reaching 60rpm with but a quick flick of the wrist at the crank. How much effort goes into moving that stator, that's the big question.
I just can't wait to see how Rick and his replicators fare!

The spring is exerting force. It needs to exert enough force to keep the stator in the first position. In order to get it to the second position, they have devised a lever/ bar setup. This will require extracting energy from the rotational motion of the disc. The disc is not generating enough torque to do this. It can't work.
