Australia's Samuel Adeloju earned the top prize at the annual 2010 James Dyson Awards, for Longreach, a buoyancy deployment system that propels help from afar to victims stranded in the water.
Longreach employs a gun-like device to shoot a projectile of rapidly expanding foam to drowning victims up to 150 meters away. The projectile, or "Life Ring," acts as an emergency flotation device and enables the stranded to remain buoyant until proper help arrives. Similar emergency propulsion devices already exist, but only shoot to about 60 meters. Longreach also utilizes hydrophobic foam, which reduces weight and production cost and makes for a more reliable and puncture resistant buoy compared to existing designs.
Adeloju is an industrial design grad from Sydney and will receive a £10,000 prize as well as a trip to the Dyson R&D center in the U.K. or Malaysia.
