The X PRIZE Foundation and Qualcomm are partnering to try to make the Tricorder -- Star Trek's famous health-diagnosing gadget -- a reality. They are offering up $US10 million in purse money. This may be the most practically useful X PRIZE yet.
The gadget that takes the X Prize must enable a person to accurately diagnose themselves (without going to a doctor or hospital) and it has to be "easy and fun to use". This is one piece of sci-fi that I can't wait to have as a reality. Get to it, geeks!
