摘要

Soap bubbles filled with helium are providing a new insight into how to increase the fuel efficiency of cars. As fuel economy and carbon emissions become more important to car buyers, manufacturers have identified cutting air resistance as a cost-effective way to improve these figures and so boost their product's appeal. Instead of using traditional wind tunnels to examine a car's aerodynamics, though, a team led by Angus Lock at MIRA, an automotive research consultancy based in Nuneaton, UK, use helium-filled bubbles.
