Dear Mr. Lamar:

Your point is very well made.

It just needs a little judicious editing for spelling mistakes and the
like.  :-)

Did you notice how NASA called it "CAFE" after the "Corporate Average
Fuel Economy" burden under which the automobile industry must work?  Do
you think NASA is trying to sanctify their boondoggle by naming it after
another?  I got my 30 mpg car because I wanted to have good fuel
economy.  I sold my 80+ mpg car regardless what the automotive CAFE
said.  I did not have to have a government agency dictate to me what I
"need" or do not "need."

I will call my representatives in DC and tell them to axe this turkey.

CAFE Foundation is a group that NASA is working with,

I think they are trying to emulate the X-Prize.

Very good write-up Paul. Actually my ducted fan experience is worse than
you write. Best speed with the ducted fan was 135 knots at 5400 engine
RPM. With the gearbox and prop I am now doing 165 knots at 6400 RPM,
since I can turn the engine up a little more.

I suppose ducted fans can be quiet, but mine was very noisy. There were
many complaints. A friend heard me fly over when I was 12,000 feet over
his house on a cross-country. With the prop and the very same engine
install, no one hears me anymore. No more complaints. People say it
sounds like any other airplane. Maybe I was pushing the tip speeds but
that was an attempt to make it as large as possible, that was still only
38 inches in diameter.

Thanks Perry. I'll add this testimonial if you don't mind.
