Manchester University’s Sarah Haigh, an expert in nanotechnology says, the invention could make waste water from toilets safe to drink. Although the result may not be bottled mineral water, the researcher says the results could be the differencebetween life-and-death in regions without clean water.
Haigh believes that a scaffold device holding a mixture of bacteria and tiny metal nano-particles will react with the water to extract useful hydrogen, with the remainder filtered again to produce clean water.
In addition to an initial $100,000 (£63,000), the group working on the innovation stand to receive a further $1m from the Gates Foundation next year if they can demonstrate the chemical reactions they propose can actually work.
The researchers plan to have a prototype ready to demonstrate by 2013.
