An Australian inventor has created a bazooka that shoots life preservers rather than rockets. News.com.au has more:
Sam Adeloju last night won the £20,000 ($32,000) James Dyson Award, named after and patronised by the inventor of the bagless vacuum cleaner which carries the Dyson name.
His entry, the Longreach, is a modified bazooka which fires an expanding lifebuoy 150m out to persons in distress.
