Fuel burn reduced from 12 GPH to 10.2 gallons per hour at same manifold 
pressure and RPM in an engine 5 hours old...  

Forgive me, but if such achievements were so readily available, they would be 
broadly used by a world searching continually for improvements in fuel 
consumption.  It sounds like the J. C. Whitney magnetic device that straps on 
to your fuel line to energize the fuel and improve gas mileage. There are 
endless testimonials as the benefits of such devices, but hard data seems a 
bit hard to come by.

I would like to see a well instrumented third party before-and-after test 
before and at least an attempt at a technical explanation that uses 
conventional physics.  Then you will pique my interest and possibly my 
enthusiasm.  Not before. 

Good data is hard to come by.  It requires carefully calibrated instruments, 
careful experiments, a constant search for error, and, most important, 
redundant measurements that corrobate one another.  But to truly convince 
folks that a major advancement has taken place you must SHOW THEM GOOD DATA.

Sport aviation thrives on endless quantities of hope, and human beings seek 
results to support the hope, but good instrumentation seldom appears in such 
exercises as it so often dashes ones hopes with doses of reality, unwelcome 
though it may be.  

Thanks for the testimonial.  Now, please, someone, show me the independently 
verified third party repeatable data collected with good, calibrated 
instrumentation.  And then do it again after the thing runs for a while.

We should all be a bit skeptical about all things, but particularly skeptical 
about breakthroughs that reduce fuel consumption 15% that have been missed by 
the rest of the technical world.  Contrary to popular belief, GM did not buy 
the patents and hide them from view to keep them from us.

My two cents. 

Ever skeptical, Fred
