Has anyone seen the article in The Economist (Dec 17th, p79)?  Some
researcher in Sweden did a study that says glide wax only traps dirt
and makes your skis go slower for "runs more than a couple of hundred
metres".

That will certainly require a rebuttal from the wax manufacturers.

I doubt that a mag like The Economist would publish a prank report,
although I will admit that editors or reputable magazines have been
fooled before.

The author of the article has come up missing.  Went out for a ski and never
returned.  The Norwegian police have raided Swix headquarters looking for
evidence.  Incriminating E Mails have been impounded.  How do you say
"Senator I have no recollection of those events"  in Norwegian.

Correct.  It's no prank and april fool's day is April 1st in Sweden.  I
haven't seen the article in the Economist, but different Swedish media
has reported about it.  It's the result of two years' of research at a
Swedish university, published in a Licentate thesis by  Leonid Kuzmin

In Sweden, a Licentiate thesis is something that you write half-way
between Master of Science and Ph.D. degree.  Compared to a Ph.D.
thesis, there is not the same high requirements for having it reviewed
vy and defended "against" experts in the field.

Interesting results, anyway.

You find more about his results and ski-preparation-tips (in English)
here:
http://www.expertsvar.nu/publicIndex.asp?page=10&PRID=5785&lang=2

I don't know if the thesis is written in English, but you have his
e-mail address on the above web page so if you're interested you can
ask him if he has more detailed material (or the entre thesis in
English).

The interesting thing to me is the possibility that the current
running surfaces are designed for (or at least contain the properties
for) absorbing glide wax. I wonder if there aren't other running
surface materials that have been rejected in the past as being
impervious to glide wax absorption that may now be reconsidered for
ski bases.

Wasn't this already discussed on this forum?  I'll check the archives
when I have the chance, but tidbits that come to my mind are - what
temps/conditions were involved, what methodology, repeatable? etc. etc.

I've been off the ng for the summer and only just got back on.  It's
quite possible I missed the discussion, just as I missed the article
when it came out.  I only came across it when I was going through back
issues trying to catch up on my reading.  Let me know if you find the
archived discussion.

There's a discussion called "Should All Skis be Waxless?", around
mid-Dec.  Interesting stuff for sure.  -zeke

And here's the link to the economist article. I googled it and was able
to read the article without subscribing.

COULD this be true???

Here is a link to the actual thesis, for those interested.
http://www.dagbladet.no/download/smoring.pdf

To me, what is interesting is that he (Leonid Kuzmin) only considers
friction from water lubrication and from dirt contamination. I wonder
if friction from capillarity attraction should also be considered as
far as wax is concerned?

The current Norwegian waxing boss Terje Langli finds it interesting, as
does a former Norwegian team waxer Geir Tufto (currently under contract
with the Sweish team). They both say that in very wet conditions,
scraping is the best approach.
