Avoiding ‘hot’ wheels

Phillipe Lothaller, a 17-year-old senior from Cape Town, South Africa, has invented a device that could save airlines big money by extending the life of tires. The metal device at left is an early mock-up of the design. A newer version (seen in white at center) has pop-up scoops instead of fixed ones. When retracted, the scoops don’t interfere with a plane’s protective wheel wells. Credit: Patrick Thornton, SSP
