Waterless coolant?

A friend recommended a website for Evans waterless antifreeze. I had never heard of this before and searched HEF and didn't find anything either. They claim no cavitation pitting or corrosion. Does anyone, (besides Jay Leno), have any experience with this stuff or is it a gimmick?
Thanks.

Ethanol...but there's the little risk of going up in flames :D

Alternatively, use all copper rads with massive heat sink along with rust inhibitor in the water.

Check out the viscosity of the stuff when cold. If I remember right, it gets really thick when cold.

This has been around in the trucking industry for years.

It is what synthetic lube oils were years ago. Hefty upfront price but long and healthy payback down the road.
One blown hose and it all goes down the drain.

My understanding is that it is basically undiluted coolant.
This has been discussed on other automotive forums.
For Jay Leno this product might be worthwhile, due to his collection sitting in a shed plus he has the cash.
However until a major engine manufacturer uses and recommends this product for their engines I won't bother with it.
Manufacturers are always interested in extended service intervals, mainly I would think as a selling tool however some of these extended service ideas have not worked out that well in the real world, often with the owner having to pay for the manufacturers bright idea. Some of these bright ideas include sealed for life transmissions which are now no more. Extended oil changes with M1, seeing a fair few gunked up engines.

Higher boiling temperature coolant is a good thing for off-road racing motorcycles and quads; they'll boil regular coolant with out too much effort...

Higher coolant temps in trucks and construction equipment give very slightly better fuel efficiency and economy, but higher coolant temps also mean higher lubricating oil temperature and more heat rejection via the oil...

$58 per gallon means a lot of money for the people selling the ethylene glycol/propylene glycol mix...

(Leno could pay $580 per gallon, and be happy with it...)
