The Cruelty Of Math
Thing Number One:
10 Sci-Fi Techs We Could Build If They Weren't So Damn Expensive. Here's #7 on the list:
New York-L.A. Maglev ExpressPricey, yes? Yes.
Cost: $70 billion (Based on established construction costs)
Thing Number Two:
The War in Iraq Costs. As I'm looking at it right now, it's just over $492 billion.
In other words, we could have built seven cross-continental maglevs already.
Update: Is Wired's math bad?
Also: 290 words. Whee!
