<VV> Re: [fastvair] Squish area article in Pop Sci mag -Long -little Corvair

[FrankCB@aol.com]

Cash,
       How about getting a look at the patent mentioned in the article to get 
more detail on this "invention"?  The Pop Sci story doesn't give us very much 
of significance.
       I'd like to see some hard evidence "before and after" type to verify 
that this concept has any merit.  Or does it belong with the "gas line 
ionizers" and similar examples of black magic.
