Its interesting but they sure seem to mix up a lot of fluid dynamics
concepts, some of their statements seem contradictory.

Aside from that, one would think they would have a at least one or two
pics showing streamlines before and after device install.

I know just a little of fluid behaviour, but enough to realise just how
complicated it is. But yet I'd be tempted to bend a few up from sheet
aluminum and attach with double sided tape...

Reminds me of one day seeing a 86 pass. Vanagon passing by (about 50
kph) as I was stopped at traffic light. It was belching, I mean really
belching blue smoke from exhaust. The great thing was that the blue
smoke really showed up that big neg press. area behind van, was as if
the van had a big pile of blue cotton wool stuck on the rear.

Aside from the medicore Cd and large frontal area, that rear end sure
makes Vanagons a drag :)

It is supposed to reduce turbulence and therefore drag at the rear of
vehicles and improve the laminar flow thus reducing fuel consumption.
Maybe it could have some slight benefit over long distances on
highways...can't see how it could help in stop start traffic where fuel
consumption is greatest anyhow.
I don't think I want to stick or rivet them to my nice paintwork...

My cynic alarm is going off and the words "snake oil" keep popping into
my head.

Anyway you be the judge....
