Clean water bottle wins UK leg of James Dyson Award

A bottle that uses ultraviolet light to sterilise drinking water has won the UK leg of the James Dyson Award.

The Pure bottle is the brainchild of Timothy Whitehead, a design and technology graduate from Loughborough University, who had the idea while travelling in Zambia.

It eliminates the need for chlorine and iodine tablets which take 30 minutes to work and can leave an unpleasant taste.
