    Why aren't planes dimpled like golf balls?

    15/06/2020 Duración: 03min

    Darren got in touch to ask us: "Golf balls are dimpled to disrupt the air around the ball. As far as I can gather, this reduces their drag and allows them to fly further than they would if they were perfectly round. Why do we not see dimpled cars, aircraft, and trains? If this effect is so effective for golf balls, why not use it on Formula 1 cars, for instance?"Adam Murphy went looking for a hole-in-one to this question, and spoke to Sam Grimshaw from the Whittle Lab at the University of Cambridge...

Is anything known about how this will happen, and the effects? How will it affect our reliance on technology?"

Which advice is correct?" We put Tim's question to Mike Childs, head of science, policy and research at Friends of the Earth. Also helping us out is Lewis Tyronney, an engineer with British Gas...
