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

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."

Fire hose

This is like hanging onto a firehose.

could it be scaled up

[strack]

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

Oh look it's Super Mario!

Seems to me they discovered the FLUDD [mariowiki.com], nice.
