A buoyancy bazooka which could save hundreds of lives in the US has won this year's international James Dyson Award. Longreach, chosen from a final shortlist of 15 by inventor James Dyson, shoots an emergency buoyancy aid up to nearly 500 feet out to sea. It is made of hydrophobic foam which rapidly expands upon hitting the water to protect the buoyancy aid from puncture. Equipped with flares for night-time illumination, Longreach allows the victim to remain buoyant for a longer period of time. http://www.dexigner.com/news/21561
