1923 Persu Streamliner
From the wik:
Quote:
Aurel Persu (1890-1977), was a Romanian engineer, and among the first to apply aerodynamics principles to automobiles. He came to the conclusion that the perfectly aerodynamic automobile has the shape of a falling water-drop.
Persu implemented his idea in 1922-1923 in Berlin, building an automobile that could reach very high speeds for that time, and it could take curves at up to 60 km/h. It was the first car to have the wheels inside its aerodynamic line, which we take for granted today. The car ran for 160,000 km and can be seen since 1961 in the "Dimitrie Leonida" Technical Museum [1] in Bucharest. The car is still working today.

Very weird-looking and unfunctional by today's standards, but quite nice in the eye of an ecomodder.
On the second and third pictures, notice the little shade/visor above the driver's side windshield. That must have killed airflow.

Certainly not what you might call an aesthetic success.

The shape of raindrops is dominated by surface tension. They are egg-shaped, without long, streamlined tails. Water drops running down a surface are probably the source of the analogy.

I wonder if that was "poor mans air conditioning"? |

Yes and no. I said the same thing to my Dad, and he went through an extensive proof that the surface tension turns raindrops into spheres when they are on their own :
I agree with the analogy, though. Our artistic interpretation of rain is as lines. Also, I think that's what cameras can see, the "streak" of the falling raindrop :

I also noticed that the distance between the rear wheels seems to be half that of the front wheels. It's almost a trike!

That the opening front window slot, can be seen on the original photo too. One question I have, did the front lights swivel too ?
