Soap bubbles to help enhance car efficiency
London, Aug. 30: Automobile engineers have shown that soap bubbles, filled with helium, could improve the fuel efficiency and take the drag out of future cars.
Using 12 cameras, a team in Britain has tracked the three millimetre bubbles which swirl around cars in a wind tunnel and found that the helium in the bubbles gives them neutral buoyancy, the New Scientist reported.
