Video Projection with PDAs!
Your local sales rep with a projector hooked up to his or her laptop uses technology that creates the image by blocking light, which is very inefficient because it uses a very bright light bulb, and only a small portion of the light makes it to the image. (And you pay an arm and a leg to replace that little sucker also!)
But the new method, being developed at the Department of Engineering at Cambridge University, will steer laser light. A black and white prototype is already working. It will be practical for consumer color versions only after the price of blue lasers drops, which is expected to happen when the next generation of "Blu-ray" DVDs becomes mainstream in the consumer world.
