Last April, professional golfer Bubba Watson announced that he had co-developed the world's first hovercraft golf cart. Because it floats on a layer of air, placing 33 time less pressure on the ground than the average human foot, the hovercraft – named the BW1 — is able to zip across fragile greens, water hazards and sand traps at speeds up to 55 m.p.h., all while seating four people and holding two golf bags.
