Well, Amos... essentially, if we were starting from scratch, a cost-benefit analysis may point in your direction.

As for me being able to "design" it, no problem. I've done it. One need only recall the old engineering saying, "Given enough time and money, we can build anything."

Now, Amos, let's talk about that bridge from California to China. Surely is would be more cost efficient in the long run than transporting goods and people by such old technology as seaships?
