A long time ago, there was a thread about how you could convert a snub-nosed
air-pusher like our vans into a sleek TGV/Bullet Train aerodynamic wonder.

Someone posted that you could take a cone of suitable size, put it on
a pole of suitable length, and stick it to the front of the van (like
the knights of old).  This gives the same drag coefficient as a solid
mass of the same length, but with a nice bullet nose.  I'm pretty
sure there's even some scanned photos of drawings of someone's research
that "proved" that putting a more rounded nose on a bus drops its coefficient
of drag dramatically on the vanagon web homepage. 

Anyway, lately I've been thinking about putting that pole with a plate
or cone on the end on my van's nose, and see how fast I can go.  Right now,
wind drag increases as I approach 90mph.  I don't think I've been above
90 (maybe on a downhill?)
