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."
