Ever since I first saw "Back to the Future II" I have wanted one of those "Hoover Boards". With Elwood "Woody" Norris' AirScooter it sounds like we might just get there. Well not quite the AirScooter still weights 300 pounds but it is progress. "Woody" was just selected to win the Lemelson-MIT Prize for his inventions including the HyperSonic Sound. The HyperSonic Sound has been called by MIT "the first big improvement in acoustics since the loudspeaker was invented 80 years ago". The technique allows you to focus sound waves and direct them at specific locations or individuals. So check it out and congratulations "Woody".
