The engine from 2000. So wrote and sang a few years ago the legendary Lucio Dalla. Certainly, however, that in a few years we could really have revolutionary engines. It seems that the key word is "superconductors". Metals that at very low temperatures behave in a peculiar and anomalous way. With the superconductors work the very fast Japanese trains, the "magnetic leavening" ones!!! Unfortunately the cost to use these technologies is still too high, but the costs will be lowered and, sooner or later, even our cars will be able to "rise", as already happens to trains in Japan. Maybe we should find "new generation" superconductors, built in the laboratory, more efficient at higher temperatures. I'm launching a call on WorldFace !!! Anyone who has news about new technologies in the field of engines, respond to WorldFace !!!
