University of Twente researchers found injecting bubbles underneath a ship’s hull causes them to be pushed against the hull’s surface making an air bearing surface. In the surface layer between the ship and water, these air bubbles cause less friction: it’s also known as air lubrication. In practice, friction can be reduced 20 percent, with […]






A team of eight engineering students from the National University of Singapore (NUS) have successfully built Singapore’s first personal flying machine, named Snowstorm. Comprising an intricate design of motors, propellers and inflated landing gear set within a hexagonal frame, Snowstorm is an electric-powered aircraft capable of vertical take-off and landing that can be controlled by […]
