Those of us who enjoy the carts more than the golf have a new reason to head to the course. What I think the real innovation is gets completely passed over by both the video and the article: noise control. Hovercraft have been around since at least the '50s (probably longer), but one of the main things that holds them back from general use is the enormous racket they make when they work. If this one is quiet enough to use on a golf course, it would seem they've finally conquered that engineering obstacle.
