Up until recently there were limited ways that a person could fly. They could get in an airplane. They could be born on Krypton. They could glue feathers to their arms and then jump off a building. (Note: this last technique worked only for people who also happened to be born on Krypton.)
But now there is a new path to the sky: The Jetlev Flyer. Attaching to your back like a jet pack, but far less likely to explode, the Jetlev Flyer rockets you into the air not with flame, but water. Think of it as strapping twin fire hoses to your back, then riding the recoil. Obviously, this technique requires a tremendous amount of liquid, so a giant hose tethers you to a floating unit on the water’s surface that pumps up the H2O. This system allows for plenty of fuel, which means you can fly for roughly two hours at cruising speed, or for a little over an hour with the throttle wide open.
Even with the tether, you get a legit flight experience. The Jetlev allows you to soar up to 30 feet in the air, while the fly-by-wire steering system lets you travel anywhere you want to go — assuming you only want to go places that are above water. As per usual, cool new technology doesn’t come cheap; each one costs about a hundred grand… but we gotta think you could recoup that investment pretty quick with a nice little rental biz in Hawaii.
So go strap one to your back and pretend you’re the Rocketeer. (Just don’t wear the Rocketeer’s clunky metal helmet… unless you can fit a scuba mask underneath.)
