Amazing Water-Jet Pack

An inventor named Raymond Li has a different idea, one which he's just managed to patent: a water-propelled rocket pack.

"Typically, flight packs include propulsion devices such as propellers, rotor blades, or rockets, which often require a highly flammable fuel in order to generate sufficient thrust for flight. In addition to having a reservoir of volatile fluid attached to the body of a pilot, the close proximity of the propeller, rotor blades, or rocket exhaust to the pilot further poses significant safety risks. ... As an alternative to employing the combustion of volatile fluids to directly generate thrust, the high-pressurization of non-flammable fluids, such as water, has been proposed to create sufficient thrust in order to achieve flight."



Here's a video showing how it works:
