UV bottle design wins Dyson's UK challenge

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

Design engineers from 18 countries have entered projects for this year’s James Dyson Award, which challenges them to design something that solves a problem.The overall winner receives £10,000, with a further £10,000 going to their university department.

The bottle was designed by Timothy Whitehead, a design and technology graduate from Loughborough University. He dreamed up the idea while travelling though Africa – realising the reliance people have on chlorine and iodine tablets; these take about 30 minutes to create safe drinking water and lave a unpleasant taste.

The water bottle works by first filling the outer chamber with dirty water from any lake, stream or dirty puddle. The inner chamber is plunged though the outer chamber and the water is filtered though a custom designed filter, down to 4 micron in particle size. Once the water is clear it is sterilised for 90 seconds using a wind-up Ultra Violet bulb. Once complete the water is safe to drink. The whole process takes 2 minutes.

Other finalists include a lifeboat from Austria that can be transported by plane for high speed rescues, a bin from Switzerland that decomposes organic waste without any smells, and a car from Australia that can drive through rugged terrain and penetrate a fire, to allow firefighters to control blazes from the inside.
