World's Smallest Car

When I first read this story I thought it was a joke, but apparently it is not. At Rice University in Houston, Texas scientists have built a car that is 1/80,000 the width of a human hair!

This is an amazing example of a new science called "nanotechnology", which many say has great potential in the coming years.

Looking through a scanning tunneling microscope, one can see the nanocar speeding across a surface of gold. The nanocar consists of a chassis and axles made of well-defined organic groups with pivoting suspension and freely rotating axles.

I wonder what kind of mileage it gets?!?
