From my viewpoint one of Archer's most important contributions was to draw my attention to the concept of "sliding rods" or "displacable wheel spokes".

im supprised no one has commented on this pic, it looks/seems very good, but id ge away from the *sliding* and try to use a swinging motion, i cant help but think that sliding = lots of friction., but hey i really dont know.

In post #471 I wrote:

Nice Gustav!  I agree the sliding rods is an interesting overbalanced scenario as you present.

Are you/others interested in building something along this concept?  I don't have time as I have 4 other projects in the works.  I wish sleep wasn't needed!

What about using skateboard wheels and bearings at the end of the spokes.  And the track would only have to be around 1/2 the wheel as you show.  And the hub/spokes should be smooth metal to reduce friction. (a more complicated setup of rollers at the hub would be better!)  And the end of the shaft could have a large pulley attached via a belt to a small pulley (like 1:4) to turn a generator - like maybe an axial flux design.

Thoughts/comments/ideas on this type of design working?

Maybe you/we should start a thread exploring this idea??

(YOU SHOULD start a topic on this as it appears to warrent further investigation)

An axial flux generator is an air-coil design with no iron cogging.

See this link for a pdf of the design:

Hi All
If anyone wants to do the last experiment I talked about then get a stack of block magnets and stack them straight up, then get a plastic tube and a steel ball, put the ball in the tube and move the tube close to the magnetic stack at about the half way point of the stack and the ball will shoot up, the ball is trying to get to the face of the magnets thats why it goes up if you put the ball before the half way point of the stack it will go down trying to get to the opposite face of the stack of magnets.

Hi All
This is proberly my last post for today but I have enjoyed today its been a big learning day for me, I have learnt theres attracting magnets that release, repelling magnets that repel straight instead of to the side, repelling magnets that you can come into and the best of all moving the centre of gravity lets you lift heavier wieght then are on the other side.

YES it got stuck but the ball at the end was shot off like a bullet . and then it was stuck there waiting its turn.

The target balls were all nonmagnetic.  Glass.  wood.
If a ferromagnetic ball was waiting there, there would be less of a force to propel the next ball.  The magnetic field would be entrained by the "waiting" ball, effectively disrupting the magnetic potential gradient.

( oh in the video i was trying to find, but didnt, the ball flew up the mag ramp and off the end( there was no ther ball at the end waiting to be pushed). and made a large crashing sound ), i guess it depends how you arrange the magnets at the end.

Now that would be interesting.  Some sort of ultra-smot??  Keep looking, I'd like to see that one.

Archer Ive built alot of things  but your  Tunable SMOT throttle/Gate idea is the cats pajamas sweet !!!!    NOW im really on the edge of my seat [wish I didn't have to go back to work]  Thanks   Chet

No kidding, that is one of the best ideas I have seen, should be able to totally modify the field to whatever shape/strength needed. I can't wait to try it out

What is the SMOT Throttle/Gate Idea?
