If I had been president, I would have come out and declared: "Nothing there, ever! This place stays as it is. We make a big place there where people can pray about the errors we have made that those two towers had to fall."

The thing is, 75 percent of design today is absolutely outdated. It all has to be redesigned with the materials and knowledge that we now have. We know so much more than what we are doing.

I was 3 years old, and we had a very rich neighbor in Berlin who drove a Mercedes sports car. I remember standing behind this car, admiring the trunk, how nicely shaped it was, for an hour. That shape has never left me - I could design it today!

1973 was the first gasoline crisis in the world. That year, I designed the first aerodynamic truck, eating 40 percent less fuel. I put it on exhibit everywhere. It was 30 years ahead of its time. Nobody is building it today, and everybody still has problems with their boxy cars and trucks eating up fuel.

It isn't easy for me to have contact with the industry, because it is so outdated. Look at General Motors, look at -Mercedes, look at Chrysler, look at Porsche, look at BMW . . . They are all building cars from yesterday! Nobody has an idea how the car of tomorrow should look. I've built them already. I have the prototypes in my exhibition, but they won't do it.

An architect has to build the building from the inside out, not the outside in!

Everybody was inspired by the drawings and the wind tunnels and the race cars - but no one wanted to work with me because I had a reputation for being an aerodynamic dictator!
