Stanley A Meyer Diamagnetic EPG Modification

(1/1)

jim miller:
The ferrofluids such as the EFH-1 from Ferrotec have the limitation of low magnetic susceptibility.  To increase Ms, one needs to increase
the % of magnetite in the ferrofluid.   There is a linear relationship between the amount of magnetite/unit  volume and Ms. But the rheological
limitations prevent efficient mechanical pumping as the liquid becomes very viscous. 

The use of paramagnetic metals such as iron, cobalt or nickel has been mentioned by Stan Meyer as one method for the metal-argonide  gas matrices.
He also stresses the problem of  an air gap as being one on the design problems with alternators.
If a very strong bar magnet were to be formed into a toroid shape, the lines of magnetic force flow around the magnet and through the center donut hole
 
In the  mechanical drive  series of EPGs  constant energy had to be used to pump the ferrofluid and to constantly realign of magnetize the magnetite after pumping and mixing of the pump

Fortunately there may be an approach that requires much less constant input of energy

1. Transitional metals such as iron, nickel and cobalt can be permanently magnetized  and specialized alloys  such as in the ALNICO or Neodymium type n50
   are extremely strong compared to the very weak magnetism of magnetite

2. If a strong bar magnet is formed into a toroid  (especially without an air gap)  the magnetic lines of force are radial in nature, going around and through the center of the "donut"
 
3  Consider now toroidal shaped magnet  placed inside a larger hollow toroidal shell  made of a nonmagnetic material such as copper or plastic providing support  coils used for pickup coils around  its circumference as in the Mechanical Drive EPG.

4 The  big problem is how to you get a solid inside another solid?  With liquids or gas it is no problem,  just pump it in.  But for a solid  one solution comes to
  mind.   Think about how one slices a bagel so that one has two donut shaped pieces of  bagel or pipe.. The toroid magnet  can now be place within a hollow solid

5  Now seam the or glue the two pieces together you now have a permanent magnet within a larger hollow toroid and then put on the pick up coils

6. So far so good, but now how do you  move the magnet???

7 Thats where diamagnetism might provide a solution     see attachment

8  A permanent magnet can be oriented by placing in between two ingots  of bismuth  while the weaker diamagnetic forces orient and suspend the permanent magnet
    A  larger permanent magnet above corrects for the weight of the magnet
 
9    So there it sits suspended with no energy being  expended,....

10 Think about maglev trains and how similar poles repel and lift the train to glide along at high speed or  rail guns that propel bullets at tremendous velocities

11  If you  suspend the  toroidal magnet between two large bismuth rings using diamagnetism,  the suspended toroidal ring should move effortlessly  jn some ways like  bar of metal through  a solenoid

12 I would evacuate the tube reduce air resistance

11 Consider the toroid ring to be just a whole series of magnets waiting to be shoved down the track with a  gentle push

12  To increase speed  appropriately spaced  thrust magnets with correct n/s orientation could be could overcome inertia and increase velocity using a linear drive motor until design output is
       reached

13 I believe the key is to have no air gap and to reduce Lenz forces  by proper orientation of the magnetic lines of the rotor and by having a non magnetic outer toroid  to support and wrap the pick up coils
 
14. I remember a magnetic levitating top ... its been a few years,  but i it was called a Levitron     Centrifugal force kept the top vertical like a gyroscope until air friction slowed it down  but in
this case you can run it in a vacuum with constant diamagnetic forces levitating.   The starting inertia of the rotor overcome and maintained by properly timed nudges of
a linear motor against small booster or thrust magnets attached to main rotor.

Concepts:

The number of lines cut is large
The velocity is not impeded by air resistance
The magnetic saturation is greater in solid magnet than in a ferrofluid
The orientation of the magnetic lines of the rotor might reduce the effects of Lenz law
BEMF reduction using plastic     copper?

In the New Zealand lecture Stan states that a magnetic field can pass through another magnetic field 
I think I'll re-read Feynman  I'm sure I'm missing something  .......Perhaps a highly pressurized rapidly circulating mercury plasma is what is needed  lol ;)
