Ed Wingate,
So, if Robert's most plausible sounding explanation is wrong, what is the 
correct explanation? As you point out, you have made and operated one and 
have direct evidence with which to attempt to determine the answer. Can you 
please share with us whatever data you have acquired, with at least a 
proposed explanation? I really would like to hear an alternative. I just 
reread this and it sounds somewhat peevish and I apologize. It isn't meant 
to be. I sincerely want to know your thoughts about the operation of the 
Marinov motor. Thanks.
Paul
