Interesting Aerodynamic Cars (Mike Vetter's ETV, also Avion)

Sometimes a car is just a car.

This one OTOH had rear view video cameras on stalks that bend back down so they are lower than the tops of the rear fenders.

Exactly!

From The Continental: The Best and Worst of the 2013 Los Angeles Auto Show, speaking about the MB AMG Vision Gran Turismo:

It is juvenile, garish, and politically incorrect, and somehow I don’t believe it would meet the approval of Daimler’s long-time chief designer, Bruno Sacco. (Bruno’s the godfather of restrained German design epitomized by vehicles such as the W126 S-class and the W201 “Baby Benz.”) But the AMG Vision Gran Turismo concept is a wonderful celebration of the joy of driving.

The Hungerford Rocket Car (aka Shirley Lois:Moon Girl), its Chevy engine only ran up to 50 mph but it was its 'forced air' rocket engine that shot out a flaming tail that pushed it up to go...70 mph and achieve a whopping 2 miles to the gallon! Th original aerodynamic shell was made up of cardboard and linoleum, later renovated with aluminum sheets.

We've been doing auto safety wrong all these years!

Wind-Tunnel Dirigible

All wrong. Viktor Shauberger showed this:


And the Edison2 VLC validates this, in reverse, using it to lower internal engine cooling air drag.

I think perhaps they were attempting to describe an internal application of the Coanda Effect.

Just a guess.

Junior High School Students Build This Model Dirigible

FLYING on a swivel under its own power, this model dirigible shown above was made by members of a class in aeronautics in Hamilton Junior high school, Long Beach, California.

A vacuum cleaner fan and motor were attached to the model and propel it about in a circle at a rapid rate of speed. It was made of wood and metal at a cost of $750 to the school.

The model demonstrates the newly dis- covered principle of aircraft propulsion invented by F. Slade Dale. The rapidly revolving blades of a centrifugal fan whirl the air away from the bow center. This causes a partial lowering of air pressure at the bow and the atmospheric pressure on the rear portions of the ship drive it forward.

The miniature dirigible was built under the supervision of John Hodgson, former engineer and aviator, now an instructor.

However, with the tab in place you can kick the air up enough to reduce the Coanda effect.
This disturbance also causes a wake behind it which, using the Bernoulli effect,
collects other streams of air and pulls them up and away from the cabin too.
