TV Goes Digital
Coming soon to your TV: views of the hottest live basketball plays from any seat in the stadium. What a better look at that three-point shot Call for a replay from behind the basket. Or better yet, follow the "view" of the ball as it goes through the net.

Right now, their fuel cell runs only on sugar cubes, since these produce almost no waste when broken down, but they aim to move on to carrot power. "It has to be able to use raw materials, rather than giving it a refined fuel," says Melhuish.
