A fan's response told me some very interesting news about a new transportation concept called  "Evacuated Tube Transport"  (ETT),   conceived by an American engineer.   If it became a reality,  it would only take two hours to travel from New York to China,  which would greatly reduce the present commute time.

Nowadays,  all kinds of technology that previously only appeared in science fiction movies,  is appearing in the real world.   The principle behind ETT is to make use of a vacuum environment,  routing automobile size vehicles in a network of evacuation tubes,  at a speed of 6,500 km/hr  (4,000 mph).   If successful,  it would only take 6 hours to go around the world.

For me,  the most fascinating aspect is that I could use the technology to visit my fans at different places at anytime.
