Proposed New SEG Type Design  by Dave Squires
========================
This design is based on the ExBxS relationship where the Poynting S-vector 
imbalance causes and sustains the motion of the rollers. 
It is an extension of Jean-Louis Naudin's PFT MK2 high voltage capacitive 
electrostatic motor.
Instead of the center ring rotating the rollers move around the ring using 
the same S-vector force. The B-field comes from the magnets. The E-field 
comes from the pre-stressed and precharged dielectric (electret). A slight 
movement of the rollers should get them moving and accelerating. No special 
magnetic patterns are required if the ExBxS vector relationship is valid as 
proven by the PFT MK2 motor.
This has not been built and tested yet. It is only a design proposal based on 
current findings and experiments done by Jean-Louis Naudin.
