Even though there has been particular focus on the hydrogen powered car (Toyota's Mirai) in recent times, perhaps there are other other opportunities for hydrogen to make an impact. China seems to be embracing hydrogen in a big way. These trams, even on a small scale, help demonstrate and test the promise of hydrogen.
The sleek, orange locomotive that made its debut this month in Qingdao, China, resembles a high-speed bullet train, at least until it moves. But this new vehicle—a tram, not a train—tops out at about 43 miles per hour, a fraction of the 200mph speeds of Japan's Shinkansen trains.
