SWASER ( spin wave amplification by stimulated emission of radiation ) is a magnetic analog of the semiconductor laser diode.We can have a coherent radiation from very thin magnetic layer material by DC current,that is directed prependicular through thin magnetic layer.
With a SEG we have all we need to get this coherent spin wave amplification,if we coat the SEG magnets with a very thin FeO layer.
Faraday unipolar effect is created in SEG rollers to get high DC current in between rollers middle point axis and outer circumference.This DC current,when it goes through thin magnetic layer,makes randomly precessing spin wave to coherent mode,and this is what we need to get strong static field formation around the SEG.
We can have the needed thin FeO -> (rust) layer by nature,when Fe magnet is not coated and stored in high humidity place.Perhaps this is the same as happened to Searls original magnets..

Here is a link to explain the SWASER effect.

excellent thanks for posting .. im trying to design the SEG on paper right now and will produce one when i get  more funds.. but i need to know wat the magnetic rollers are coated in .. and how thin the layer  must be to gain that anti friction zone for the unilateral friction free spinning rotaion to go around the coil...
if u have any more cgreat advice please keep me posted. jonathansimard@hotmail.com
