Waterskiing is so passé. This summer, you'll be able to fly with Raymond Li's water-powered jetpack, which is going on sale in March. It's only $99,500!
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. "It's the same reaction force a firefighter experiences when he points a water jet at a fire," says Li.
But it's much more easily controlled — the pilot can use hand controls to adjust the water pressure to make precise movements.
The jetpack was on display this week at a boat show in Germany, and it will be available for purchase starting in March, with a $99,500 price tag. New Scientist says initial sales will likely come from resorts and rental agencies. But it could prove useful for water rescues, marine inspections and even peackeeping missions, Li says.
I can just see a battion of Marines storming the beaches now with such a device.
Am I the only person who thought Super Mario Sunshine?
I'm with ya LarryL, just imagine those attached to a ship and sailors or "marine" can hop around.
Oh that looks fun...
except for the price
While that is certainly cool, the color of the hose could need some work...
this is great till some "X-treme sport" dofus cuts the supply hose w/ the water jet "exhaust" or better, they can't resist urge to stick once connected foot into water stream!
I like fun things, but this look so stupid. How much fun can you actually have by hovering above the water? It's basically like a personal para-sail. They look fun when you see everyone on them, but once you go up in the air you realize how stupid it is.
ok i just watched the video, i'm even less impressed. Can you imagine how noisey it must be to hear all that water pressure next to your ears, not to mention the motor right below you.
Gee.. I have some cpvc hose and an inner tube and an 8HP trash pump. A few more parts an maybe I can fly.

@drinny: Water pressure doesn't make any noise. Perhaps you mean the noise of the water leaving the hose -- which would be no more than the noise of water leaving a fire hose. As for the noise of the engine -- I would guess that it's no more than the noise of a jet ski, with a lot more separation.
As for fun -- it looks like a lot of fun. If you don't like it; just stay on shore.
@xlar: Yeah, the price is too much for me too. But, I expect that they'll be affordable to rent at resorts or marinas near you soon.
Wow. That is really really cool. Someday if I get rich and it goes down in price I'd definitely get one of these. Looks super fun! :)
@Lord Elliot No your not the only one, if anything it seems inspired by mario sunshine!
Typical personal flying machine invention video. Usually the noise is muted or masked by music. The poor neighbors on the dock trying to relax with a wine cooler are suffering with the terrible noise.
Moller's Skycar video on youtube shows it to be very loud, but it's touted as a vehicle that can operate in neighborhoods.
It looks like very limited mobility, and not much of a thrill after the initial novelty wears off after the first ride. I am surprised that they did not vector the nozzles out more to make it more stable as they do with other jet packs. I suspect that one doesn't fly long, that it is extremely noisy, and that it would be quite dangerous if one's body parts come into contact with the jet stream, which does look possible with the current design. I also wonder one can accidentally go too high and pull the pontoon out of the water. That would cut off your water supply and then bring you crashing back down.
I agree with comments on the hose. I would go for something transparent, or at least camouflaged blue.
Yes it needs a better color. also It would be better if the hose was smaller or a little longer. we could fly higher. also I wounder about sound like everybody else
Man, you guys are smart! A camouflaged hose. Brilliant!
I assume he chose yellow so people could see it and not run into him or the hose.
Not exactly the hover board I was hoping for.
Sure it's cool at first glance but I just don't know
how this will catch on,not to mention ALL the safety issues.
You should put a turbine in the trailing little device, so that it spins the rotors, and produces hydroelectric energy.This could then power the jetpack, so you only need a precharged battery to start the jetpack.
