Depending upon how well this would hold up in a cave, it
might revolutionize cave clothes. Imagine a cave suit or pack that
never gets wet or
muddy. <http://www.ted.com/talks/mark_shaw_one_very_dry_demo.html>.

Where would be the fun in that? Part of the attraction of caving is the wet and
muddy bit!

This means Bill's rocking people's packs won't work anymore as rocks will
slide off and out of the bags he rocks.

What does it do when it enters your bloodstream or groundwater?
Teflon, scotch guard.....they're quite literally, a part of every one of us.

Or on the other hand it will be easier to slip in that special rock!

My guess is that since it is essentially impervious to
water, it will not enter the body or the groundwater to any
significant extent. Bits could be sloughed off, but if not attached
to anything my guess that they will be quickly flushed through the
system. However without knowing the chemistry of the coating, it is
not possible to give an accurate analysis.

I couldn't find anything about breathability of the
superhydrophobic coating. They say it works by trapping a layer of
air on the surface of the material, so it might breathe. However it
is supposed to be nanotechnology so the pores would obviously be
small and it might not breathe easily, sort of like Gore-Tex.
Unfortunately for caving applications, it sounds like it
might not hold up well. Several places they mention that abrasion
reduces performance.

According to the MSDS, The LD50 for rats is 5800 mg/kg (i.e., it takes
a lot to kill 50% of the rats) and it is not a hazard to fish (the
LC50 is also high). It breaks down relatively rapidly in the
environment. Just for reference, LD50 of water for rats is >90 ml/kg
(http://conspiracyfactory.blogspot.com/2007/05/everything-is-toxic.html)
I wonder what this means for its useful life in protecting things.
Presumably, you need to recoat regularly.

I would like to nominate Mark's last post as one of the top 10 most
interesting post in the history of CaveTex.

Cute, but none of those demonstrations involved trying to _rub_ mud
onto a surface. If the trait really depends on a thin film of air
trapped on the surface... -- Mixon

On April 1st, a project will begin in Lechiguilla Cave to to use the new
supercalihydrophobic coating to stunt the growth of the infestation of
minerals seeping throughout the tiny orifices in the walls and ceiling of
the cave.
Cavers will be needed with low-pressure sprayers mounted on their backs to
apply the coating.
One of these outcroppings, the dreaded rimstone dam, will first need to be
drained of any liquid contaminants and thoroughly dried before applying.
