Best Inventions of 2003

Inventor: Bruce Burrows

They say practice makes perfect, but sometimes you just need better equipment. MAC Powersphere drivers help golfers improve their game by redirecting wasted energy from their swing back into the club head. The distinctive-looking titanium golf clubs have a hemispherical hole (known as the magnitude amplification cavity, or MAC) scooped out of the bottom that is supposed to capture shock waves from your strike and send them back toward the ball. When TIME compared the MACs to two popular drivers by other makers, we were able to hit balls a bit farther, with no loss of accuracy, using the MACs.
