When I was a kid, there were often ideas and illustrations on cars that was "flying" high between skyscrapers as if gravity didn´t exist. I was dreaming about them and was sure that if I should live beyond year 2000 this was the ordinary way to move
I still dream of the zero-gravity vehicle, but I am sure I will not live long enough to see container ships going 80 knots...
The global warming is not causing flatter seas and I would rather buy shares in tankers and cargo ships that goes under the surface than on top...
