Kapanadze and other FE discussion

[mkjekyll]

lanca,

Yes you are mostly correct except I do not agree that Tesla was handicapped intellectually simply because he did not leave notes of calculus and transforms all over. Much of his work went up in flames and much was performed in his head and not written.  His patents are written well enough to protect but minimal enough to obfuscate. 
Machines built by his company are still running in small parts of the grid.
Proteus job was to define Tesla's work in expressions of math and by doing so is closest to the grandfather of the EE
I suppose you and I differ on opinions of the Man as I think he was quite brilliant, in this we shall agree to disagree. Building logic gates before 1910 but also a man of his time so some things he said can be seen with 20-20 vision backwards as questionable.  However these instances do not detract from all he built and left us, and I am sure there is much more to his work than you or I have been allowed to see.
Maybe in Germany his work was not eliminated from the history books, here it was for sure until somewhat recently.

But of course Laplace is important for all RF analysis, and Leigh Page for going outside the neighborhood.

mkjekyll,do you know an easy way to get " ultra- low" friction bearing ?
When the SKF/NSK conventional bearing by 3000 RPM e-motor revolutions guarants 20000 hours lifetime,this above rotor device with 18000 RPM would by 8766 hours/year need a fast bearing change !

Linear calculation : 6000 RPM = 10000 h 12000 RPM = 5000 h 18000 RPM = 3333 h
2 billions bearing rotations ( under torque load) seems much , by divison 2 billions/18000 RPM ~ 1850 h life
All 3 months bearing change makes RF converting machines relatively expensive. !
                                                                 √18000 (RPM)~ 134 (RPM)

Are similar devices industrial known and available  ?"Citing documents : Rolls Royce ( turbines)  and Schaeffler( FAG Kugelfischer) "

I am thinking in the " fractional MW" range 1-10 KW,for high KWs the solution can be :

What was Teslas Turbine bearing in use  ? Lifetime. ? e-storage flywheels ?

lanca,
I do not have time to read the link you sent right now but for lets say the bearings in a Porsche Turbocharger are ceramic to withstand high RPM and temperature or fluid bearings.

Depending on load radial or axial, some use combination of bearings.

Like you said magnetic is a good choice but I am not aware of load capability on those.   The tried and true are hydrostatic fluid bearings.

I will get back to your links later, thanks

lanca,

Only one page came from that patent app when I clicked to translate to PDF so I could not grasp the gist of the concept.

As far as what kind of bearing on the TT back in Tesla's time he used I have no idea but can look into it.  He used special nozzles from some manufacturer so assuming he found the best source at the time.  There was something about the materials not being good enough at the time such as warping, but one never knows if this is part of the disinformation as with much to do with the boundary layer turbine design he came up with has been propagated.  I am not sure the turbine ran on what most people think of being steam but may have been designed to run on LOx since Tesla really liked the Linde system.  This would be a good way to go because all friction generated heat could be used as fuel as long as the expansion could continue without freezing things and if it was designed as such the bearing would likely have been air/gas bearings.  But of course I could be completely wrong on the LOx angle.  The particle beam was designed to run on air pressure to create a vacuum to allow for a vacuum tube that could fire nano projectiles out the open end and retain a vacuum on the cathode end, so he did consider using air for things like this and his oscillator too.

With these cool new multi-pole magnets Wesley brought up seems like magnetic bearings are mega-market potential.  If the race can float equidistant from the shaft with enough force to prevent touching and galling the surface and also center itself axially then this would be huge!

I seem to recall having a hard drive that used the multipolar magnets on a solid ring, so the technology is not so new, but perhaps this CNC magnetizing probe is the latest breakthrough.

Bearings, probably why the educational info evaporated.
