The world’s fastest train is being tested in Japan and some lucky people have been able to ride it. It’s a maglev, and can reach speeds of 500 kph (which I can’t imagine even when I translate it from metric, ~300mph). Soon after departure, the train’s wheels retract and it floats 10 centimeters above the track. Some say this is the key for the future of Japan, creating new economic growth, but some think the cost will be prohibitive . Regardless, the technology is fascinating and makes me feel more like that fictional future of the new millenium may actually arrive someday. (via SlashDot)
