Usual disclaimer; I merely looked them up.

For reference, I found the article in the November 1958 issue of
Scientific American, page 145.  Not very good in terms of building
one.

Fy amusement-

"The Amateur Scientist," by C. L. Stong
ISBN 0-671-20833-0, pub by Simon & Shuster -1960.

Has plans for Hilsch vortex tube, plus other goodies - make your
own Van de Graaff generator!

Also, the article was reprinted in the book Scientific
American Book of Projects for the Amateur Scientist, edited
by C. L. Stong.  Lots of other fun stuff in the book --
can't remember the publication date, but lots of libraries
have the book.  (I bought a copy used in high school, when
I was building a Van de Graaf generator.)

I seem to recall that plans for a simple version of this device were
published in a short article in Popular Science.  I believe that it was an
October or November issue in the late 1970's (probably 76 or 77). 

The article used common hardware store stuff to construct one, but the
basic principles and dimensions could be tweaked by a machinist to improve
the efficiency. 

Hmmmmm!! I think I might try to find the article and try building one myself.
