Will Your Next Car Be Covered In Morphing Dimples?
cartechboy writes Golfing and cars, not much in common there. But that's about to change thanks to a new technology from a research lab at MIT called Smorphs. The idea is simple: put a set of dynamic dimples on the exterior of a car to improve its surface aerodynamics and make it slipperier, and therefore faster. Pedro Reis is the mechanical engineering and research spearheading this project. A while ago Mythbusters proved the validity of the dimpled car form in a much more low-tech way. The concept uses a hollow core surrounded by a thick, deformable layer, and a smoother outer skin. When vacuum is applied, the outer layers suck in to form the dimples. The technology is only in its very earliest stages, but we could see this applied to future vehicles in an effort to make them faster and more fuel efficient.
It is a lot. Why car industry does not make cars like this?
Why not just press dimples into the plastic/fibreglas/metal panels of the car? No expensive technology needed, and "good enough" dimples can just be made part of the parts molds/presses.
On a second topic, I would be investigating this if I owned a racing team because anything that decreases the fuel consumption of my car improves overall race performance. Skipping a single refueling stop is a big deal. Since the teams are already making custom cars, the cost of adding dimples should be negligible compared to the overall cost of the vehicle. Not quite something for nothing, but close.
