In China, trains are testing "floating in a vacuum" trains - this is the answer to Elon Musk (2 photos)
It is reported that in China, such trains will be able to transport passengers at speeds up to 1000 km/h. The system resembles Ilon's project Hyperloop mask: here the trains do not go on rails, but hover in vacuum tunnels. By the way, trains in China already reach the speed of 350 kilometers per hour.
