Car manufacturers have been experimenting with electric cars for many years, but the results are that these cars are not as fast as conventional cars. Another thing that is not so good about these cars is that recharging the batteries is not as simple as filling a car up with fuel. However, in the future these problems may be solved.
Another possible future power source for cars and many other things is fuel cells. Fuel cells produce electricity from chemical reactions, like a battery. A battery uses chemicals stored inside it, but a fuel cell has an external fuel supply. It can produce a lot of power quickly, just like a car engine but it is much more sufficient. There is an experimental car being developed in Germany that runs on liquid hydrogen fuel. It has a hydrogen tank in the trunk and is filled at a hydrogen filling station.
Solar-powered airplanes, Electric and hydrogen-powered vehicles, "Super buses", the comeback of the rail system in countries with severe traffic problems; All of these things, with the exception of the railway, sound like something from "Back to the Future." and are all ways that transportation will be changed in the future. Super buses are buses that can travel over the
