   One point Ken mentioned made be wonder.

   "The rollers will become roller gears and hold everything in perfect
   synchronization".

   Replace the word "roller gear"  with  traction wheel technology ala
   Rotrex design and we could be on to something.   The oil breaks down
   over 80C however.

Doug,

These rollers would have to use friction in order to work as well.
Traction fluid drive has been done before just like you said. But
apparently his works without friction. Cant wait to see this.
