If there's one thing that needs to be aerodynamic, it's an airplane wing. Conventional wing designs however, suffer from a glaring weakness in this respect: the joint where the main wing meets the trailing flaps. Michigan-based FlexSys has developed a way to optimize wing aerodynamics with FlexFoil, a seamless variable geometry airfoil system that could deliver fuel savings of up to 12 percent. Read More

Cars don't need to have their engines running when they're stopped at red lights. That's why a number of automakers have developed start-stop systems, which stop a car's engine when the vehicle comes to a halt, and start it again as soon as the gas pedal is pressed. Bosch, however, is taking things farther. Its new start-stop system shuts the engine off not only at stops, but also whenever the car is coasting. Read More

The refrigeration units used in cold transport trailers are typically powered by small diesel engines, which use up non-renewable fuel and release greenhouse gases, just like their big brothers. The US Department of Energy, however, is looking into an alternative. As part of a two-year pilot project, it’s equipping four such trailers with clean-running hydrogen fuel cells. Read More

Engineers at GE think they could have a revolution on their hands, thanks to the new jet engine they've been working with that runs hotter than any of its predecessors. When combined with some other design changes, they figure their so-called ADVENT (short for ADaptive Versatile ENgine Technology) design could improve fuel efficiency by as much as 25 percent, extend flying ranges by 30 percent, and boost thrust up to 10 percent over contemporary engines.
