Anybody watch Mythbusters tonight? Very interesting episode.

Quote:
The show's team completely covered a last-gen Ford Taurus with modelers clay and figured out that it would achieve about 26 mpg at a constant 65 mph. They then went about adding over 1,000 dimples to the car's exterior. To keep the experiment consistent, all 1,082 dimples removed from the clay exterior were put in a box and set in the back seat so that the car would weigh exactly the same as before dimpling. The theory is that, like a golf ball, the dimples would reduce the car's drag through the air, thus allowing it to travel the same distance at the same speed using less fuel. The result? Over 29 mpg.


Clicky

I wonder if the principle would work with a streamliner?

Yeah I watched that, let me put it this way:

Would you drive it for a FEW extra MPG? Not the nicest car to be driving around in.

Although the principle is very, very good. Mr. Green.

I preferred the "Beer and liquor, never sicker." portion of the show.

I watched it the other day, then worked out just how inaccurate the tests they do actually are.

(it's still quite a good show though)
