PlainBlack writes "Possibility isn't limited by technology. And it's certainly not limited by human imagination. What makes something impossible is the lack of cold, hard, cash. Wired blog takes a look at 10 science fiction technologies we could build, if they weren't so expensive. 'New York-L.A. Maglev Express - Cost: $70bn (Based on established construction costs). At $70bn, it's tantalizingly affordable by the standards of this roundup: a train that could beat airliners from one side of the country to the other. Many agree that Maglev has enormous potential. Bite-sized examples are in operation all over the world. Birmingham, England, had the first in the 1980s, though the promise of airliner-like speeds on land is still unrealized. The British system sped along at a pathetic 26MPH and was designed to get air travelers to the planes, not to outrun them.'"
The most difficult thing in the world is to know how to do a thing and to
watch someone else doing it wrong, without commenting.
