Interesting post by cH2ange about hydrogen fuel cells, as a clean energy alternative to conventional gasoline. The fuel cell electric cars, like Toyota Mirai, are already available in some countries. The hydrogen cars run on an electric engine. The benefit of hydrogen powered car comparing to electric battery-powered ones, is that it takes just few minutes to fill the hydrogen tank.
Though, there are quite opposite opinions about hydrogen fuel cells. Watch the movie and let us know what you think via comments.
