AeroTrain

The high-speed transport system has wings, and flies at the height of 10 cm above the ground and at the speed of 500 km/h, while moving within and along a train guideway, which is U-shaped in cross section. The transport system uses well combination of the principle of flotation and the ground effect#3. This causes the train to take a minimum running resistance, and results in reduction of the energy consumption by the train and allowing use of the small drive source of the train. In addition, flame-retardant magnesium alloy (Mg-Al-Ca, developed by AIST) is used for making the train body. Use of the alloy also contributes to the running resistance reduction. Those reasons enable the electric power generated by renewable-energy based power generators, such as solar battery and wind power to drive the train #4.
