Interesting picture of a Man flying thru the air using water pressure, instead of the Hydrogen/Oxygen gas jet.

Pretty powerful pump used. To lift up a 180 lbs man, plus
the weight of 30 meters of pressurised water.

Pictures here, plus a video

Another way for man to wreck the environment. Does anybody know how many fish per minute this thing will pump? Fish larvae are small and I think they would be vulnerable to being sucked up into the machine and destroyed. No fish larvae = no fish later. I can just see a large fish getting caught in the intake and cutting off the water supply. Instant loss of propulsion would ensue. A crash landing would then occur. Not a nice scenario. Does anyone else see a problem with this?
