Formula 1 aerodynamics will make grocery stores more efficient

No, that's not a typo. It turns out Formula 1 racing technology, specifically aerodynamics, can help rid grocery stores of the so-called "cold aisle" issue. Using aerofoils that are designed to guide the direction of air flow around a race car, Williams F1's engineering department and UK start-up Aerofoil Engery aim to keep the cool temps inside the open refrigerators at the market. The aerofoils attach to each shelf, guiding the cold air so that not only is that section more comfy for shoppers, but energy use is reduced as well. In fact, Sainsbury's, the second largest grocery store chain in the UK, is already testing the tech. "This Formula 1 inspired innovation has already shown it can cut carbon produced by major refrigerators," said John Skelton, the retailer's head of refrigeration. The project is still in the testing phase, so if could be a while before its ready for widespread installation.
