Pixel e-rail Switch (maglev)




Existing magnetic systems in Transrapid and Japanese one have big coils, need for helium cooling. Their switches consists of concrete blocks with magnets - so heavy, slow and not reliable.
SkyTran has more agile rails as linear electric motor (I didn't see the detail explanation so could be wrong), however, their switches could have weak point (claim to have not mechanical switch) since there is a gap for the suspended cabin.


In my pixel maglev rail system where each coil create it's own field, it is possible to have variety of patterns.
For instance, if we have 4 coils in the row side coils work as stabilizers (red), some for movements (blue), some iddle (white, autoinduction work),  or first part work as stabilizer, middle as mover. If we have strong wing or need control turn in switch 3 to 4 rows could perform the action.





 When the number of coil pixels is essential the gap for the car safety will remove only small portion of the pixels, not essentially reducing control and levitation power.  



 In automatic mass production the cost between one big linear motor coil (like SkyTran) and many small one will mainly depend on the overall copper mass, so with pixelisation you may gain more control for the same price.
