NASA Unveils Centennial Challenges

wonderfesten writes "NASA has finally got its Centennial Challenges program off the ground. Like the X Prize, the Challenges award cash prizes to private inventors who come up with solutions to problems. The first challenges are to design a light-weight, ultra-strength tether and a means of transmitting power wirelessly. But with a prize of just $50,000, will anyone give it a shot?"
