An anonymous reader writes "As an alternative to maglev trains, Japanese researchers are working on ground-effect vehicles. A ground-effect vehicle takes advantage of fast-moving air and uses some stubby little wings to fly just above the ground, like a maglev without the mag. This is a tricky thing to do, since you have to control the vehicle more like an airplane than a train: you have to deal with pitch, roll, and yaw and not just the throttle. A Japanese research group has built a robotic prototype of a free flying ground-effect vehicle that they're using to test an autonomous three axis stabilization system."
