Submission + - Water-Powered Jetpack Finally Goes On Sale (popsci.com)
NeverVotedBush writes: The JetLev jetpack consists of a lightweight fiberglass backpack connected to a hose that sucks up water. By separating the engine and its fuel from the backpack, Li was able to drastically reduce the backpack's weight and therefore the amount of thrust needed to get airborne. The device's thrust-to-weight ratio is three times better than that of a fighter jet, according to New Scientist. The jetpack produces 430 pounds of thrust, letting its pilot fly forward at 22 mph and reach heights up to 30 feet. $99,500.00
