Inventor Creates Flotation Device Bazooka 144
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."

150m isn't that far (Score:3, Interesting)
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.
echo -e '150 m / 20 knots\ns'|units -t1 if you want to play with the conversion yourself.
