Re: Searl Rotation a Thermal Effect?

Hi Jerry,

fascinating post!

This reminds me of that simple experiment with a 12V car battery, a couple
of bearing races and a shaft. Basically, when a heavy current is passed
through the ball races of the bearings a high speed motor is created. Its
an awsome sight to see a shaft, mounted in the pair of bearing, rotate at
huge rpm.

The principle of operation behind this motor action is as unique as the
device itself. I had the opportunity to discuss this subject with Stefan
Marinov a few years ago. Stefan had done some considerable research on the
topic and offered what I thought was a beautifully simple explanation: As
current passes through the ball bearings they heat up and expand
perpendicular to their tracks. This creates a pressure in the bearing race
that is relieved by rotation of the system.
