Subject: RE: USDCT FAKES AND COPIES
Richie - did somebody yell "Hey Stupid" at Stone again? I don't know
about the rebreather, but the jerk copied my scooter, and he copied the
wrong version and then blew that completely. I can tell you , from the
Cis Lunar that Zumrick showed me ( assuming this is the one you are
talking about), that it is NOT a copy of the current EX-19, so for once
you and I agree. By the way, does the Cis Lunar still have the ancient
DECAP crap in it ( the seven year old one)?

This is pretty funny.  I've seen this misconception before.  The only
thing
that doesn't make sense, however, is that Bill Stone published a series
of
articles outlining the basic design of his rebreather, long before he
even
knew the EX-19 existed.  So, let's see: The USN has a top-secret
rebreather
development program, and Bill Stone publishes his ideas all over the
place.
If any copying was done, in which direction do you think the copying
went?

My honest answer? I don't think either tried to do any copying.  I see
convergencies in nature all the time. It's no surprise that clever
engineers
will arrive at the same optimal solution to a specific problem.
