Here is a website for a predictions exchange where you can earn "money" by betting on the future of science and technology:
Hosted by Popular Science magazine, the site gets you started with $250,000 PopSci dollars. By betting on predictions that you think will happen, you
compete against other players (2,300 of them so far) for prizes. Looks like fun.
