Now that the powers that be in the world of swimming have removed the ugliness of technology, by banning the LZR Racer Speedo swimsuit, I have invented a better way to put high tech into swimming. In fact, I've invented a whole new sport worth billions, and I'm going to just give it away.
Here's how it works. The goal, as usual, is to race some number of laps in the shortest time. The swimmer is allowed to wear, in addition to his modest swimsuit, a powerful motor of any kind, plus whatever helmet and pads he (or she) deems adviseable. The motor is operated by the swimmer's teammate, the 'navigator', who sits on dry tile with a remote-control pad. The swimmer's job is to get his body and the motor into the ideal position for supreme-speed efficiency at all times, and to manage the turn-around at each end of the pool. The navigator is responsible for accelerating as much as possible during a lap, and decelerating near the end of a lap to avoid killing the swimmer, by breaking his neck in the the fast-rushing water, or by slamming his body against the end of the pool.
I'm afraid the paying crowd (and they will pay a lot!) will be more interested in whether any of the swimmers is bashed to death during the race. But hey! That's why this sport will be worth billions.
