Tethered, Water-Powered Jetpack Provides Two Hours of Flight Time

Posted by Soulskill on from the fun-on-the-lake dept.

arshadk writes "Unlike 'ordinary' jetpacks, the JetLev is actually two vehicles, tethered by a hose the thickness of your thigh. On the water is a small speedboat-like unit which contains a 250 horsepower motor and a pump. This is connected to the pack — into which you strap your frail body — by a 10-meter hose. The water is pumped from the sea or lake below up to the nozzles on the jetpack, providing a 1,900-Newton thrust, enough to lift a human weighing up to 150 kilos."

    This is like hanging onto a firehose.

  2. could it be scaled up by strack · · Score: 1, Interesting

    ive always wondered if this sort of thing could be scaled up to pump high pressure hydrogen or oxygen up a hose attached to a rocket as its taking off for the first 10-20 km of its flight. or maybe a superconducting cable, or just pressured air for extra thrust. then the hose breaks away, and splashes down in the ocean
