WOW! At first when I saw the title of your post I was going to respond with a smart-ass comment............ BUT THIS IS REALLY COOL!

Now, the question is: How are you going to incorporate this into your truck's interior?

Hope all is well.

Very cool Thanks

That is a very cool demonstration. Thanks for posting. Now I can levitate my 125# second gen doors right into position with ease. Lol!

I tried to read a bit on "quantum locking"/"quantum trapping" so that I could understand how it worked - - - - - it suffices to say that I couldn't follow it............

If anyone can explain it in more simple terms, please do.

Thanks! Very interesting. :thumbsup:

I'm with ya Brandon!!

Cliffnotes version needed here too!! LoL

[DIGI-TAILS]

Interesting!!! Thanks for sharing... :thumbsup:

Several chiller manufacturers are already doing something similar in their compressors. The bearings are magnetic and levitate the shaft and impellar producing a no friction bearing. The efficiencies of these machines are far above typical bearings and allows the machines to operate with absolutely no oil. How long until this is available for crankshaft mains? I don't know, but imagine the power and efficiency possible from and engine with zero bearing friction!

BTW - these chillers are not "pie in the sky". You can purchase from several vendors today.

I understand how a magnetic bearing works. The shaft will always be centered within the magnetic field. This technology allows for a "locked" position within the magnetic field. I'm very far from an expert in magnetic fields, but from what I know, this is beyond anything commercially available in a magnetic bearing. Liquid nitrogen frozen superconductive materials would be difficult to apply in most applications from a temperature control and cost perspective ......I think

Agreed, the specific technology shown is different, except the magnetic bearings do also positionally support the shaft and adjust to maintain center in a somewhat similar fashion - albeit by adjusting the magnetic field electronically instead of with a super-cooled magnet - and can positionally support the shaft in any position if desired. It does so to conteract the uneven forces on the impellar, both point loads and moments in the longitudinal and radial directions. 5 years ago, that technology was unavailable too mainly because the microprocessor power was not fast enough to adjust the ~20,000 times per second required. My point was more to the fact that these kind of things are coming to market and will eventually have a place in our vehicles.

[wiedemab]

I see what you are getting at -- - The "magnetic bearings" control systems adjust the magnetic field to keep it centered, or in whatever position it deems desirable in reaction to variable load. Pretty cool.

I will try and explain the best I can .........The magnets float above the track. Thats way above my head, Very cool to watch..LOL
