Hyperloop system

Hyperloop system- the revolution of  the transportation.
Nowadays, even though the highest speed trans, the
High-speed rail, have already saved us tremendous times, it still have to cost 2-3 hours for us from Taipei to Kaohsiung. Therefore, something extraordinary come out- the Hyperloop system which exceeds every single transportation in the world. It can reach the speed of 760 mph using very little energy. The concept of it's operation is quit simple. It exploits the vacuum and the magnetic levitation. In this case, there is little resistance that would decrease the speed of the vehicle since we put out all the air inside the tube. Not only can it save people immense times, but also can it be environmental friendly to out nature. I believe that each of us can meet this great invention in the near future.
