Inventor Creates Flotation Device Bazooka 144

Posted by samzenpus
from the point-shoot-and-save dept.
Australian inventor Sam Adeloju has won the £20,000 ($32,000) James Dyson Award for inventing the coolest piece of life-saving equipment ever. The Longreach is a modified bazooka which can fire an expanding flotation device up to 150m to a person in distress. From the article: "Mr Adeloju told NEWS.com.au that the Longreach was inspired by a grenade-launch training session with the Army Reserves. Weighing just 3.5kg, it shoots the rescue device 150m in a manner similar to the way the army uses a grenade launcher to deliver flares and aerial observation devices. Hitting the water activates an expanding foam unit in the Longreach rescue unit, which also incorporates LED illumination and a vortex air whistle."

      Probably takes some training to be good at shooting it accurately. For example I worked as a lifeguard for several summers when I was in high school. When we threw rescue tubes (those red foam things), we were taught to always overthrow the target and then pull the tube back toward the victim so they can latch on easily.

      From my understanding, the launcher is 3.5 kg, which means the buoy it's firing probably weighs less than that. It'd still be a problem, but it'd certainly hurt less.

      If I'd have to make a wager, I'd say the risk of hitting a person in the head with the projectile is much less than the risk of that person having to swim 150m through rough seas to get to a raft dropped off the side of a boat.

    • by afxgrin (208686)

      A refinement to the device would be a range finder, with programmable deployment pod. Instead you fire it over their head, so when the floatation projectile reaches the specified distance, it suddenly expands and drops instead of beaning the drowning person in the head. This would probably push the price up a bit, but makes it particularly cool.

      considering it's not designed for accuracy I doubt anyone will hit anyone at 150 meters (1.5 football fields).

      It takes top atheletes nearly 30 seconds to swim 50 meters, and average swimmers at least double that [blurtit.com], meaning a minute and a half to 3 minutes for someone to reach you 150 meters away.

    So someone 60m from the boat will only have to swim another 90m away from the boat to get their floatie, when the jackass firing the thing misreads the directions.

    And then there's the chance someone will just toss the whole unit into the drink, thinking it's the flotation device.

    Here's my invention: in situations where people are likely to go overboard, require them to wear flotation vests.

    • The device described just runs out a leader line and you then come out in a boat on that line hand over hand.

      This is a device that lets you shoot a life preserver out and the person saves himself.

      In addition, this is designed to be shot to a person, not to the deck of a ship.

      So they're in the same family I guess, but this is not the same. I doubt this one is really the first of its kind either, but the most important thing is that it work well and become available. Let's hope for the best.

Good show, by the way, and Season One is available on netflix streaming..

  • There doesn't seem to be much in the way of aiming assistance from the graphic. If there's enough force to shoot the payload 150M then I'd prefer it land a few meters near to me but not on my head if I were in need of its help. Aiming as shown could put the thing 100M away.

          Infrared lasers can blind you, too, and since you can't see the infrared you don't have the normal blink reflex to protect you.

          Apparently this is a problem with some (many) of the newer green laser pointers that operate by doubling an IR laser to get to green.

      this thing (probably) is purely balistic, so once it is fired, there is no way to compensate for sudden wind-gusts or anything, putting actual guidance electronics on it and some method of course correction probably makes this way to advanced/complex

          • If you take into account that the launcher itself could have already compensated for distance and initial wind drift the projectile would only need to make minor adjustments, mostly not to hit the exact point the laser was on, ie the person.

    Assuming this is designed for use on large ships where MOB is a distinct problem (consider how difficult it is to stop and turn around an aircraft carrier or container ship), at 20 knots, you'd have to notice the man overboard and fire the device within 15 seconds. At a carrier's max speed of 35 knots, you have less than 9 seconds. While it's certainly an improvement over hand thrown projectiles, it doesn't have enough distance to handle likely scenarios.

        In my experience, once people get into trouble on a beach, they tend to be unable to swim or be in waves, which makes lifesaving devices pretty much useless. You have to actually go out and get them by swimming or using a boat.

          I've a reasonable fraction of my life along the northwestern coast of Denmark, which has some very tricky beaches. The most dangerous places can be those without waves, especially if it's windy. An area with no waves in strong winds is a sign of very strong undertows. The locals learn to read the waves, but tourist think "what a lovely calm piece of water, I'll swim there". They then get dragged out to sea, and even the strongest swimmers can't fight the currents. Many drown not from being overwhelmed by waves but from exhaustion fighting the currents. A flotation device would be perfect in those cases. They'll be able to keep themselves afloat and much easier to spot and retrieve by boat or helicopter, because there is no way anyone sane would be swimming out after them.

          • A flotation device would be perfect in those cases.

            If the currents were faster than swimmers could swim, then I'd expect you to quickly outdistance 150m. Though even in those cases, if you got close enough into the same current, it'd probably be close enough to be useful.

            Of course, people will still find all kinds of innovative ways to drown themselves...

Warning: Rips are faster than a human can swim and WILL drag you out to the deep stuff in no time unless you get out of it by swimming sideways.
