- 'Scaffold' device will capture and clean water
- Toilet water 'wont be mineral water' but safe to drink
- Could save millions of lives in the third world
Next time you see a dog lapping thirstily at a toilet bowl, pause for thought - next time, it could be you.
A new invention - funded by Bill Gates - aims to turn used toilet water into drinking water.
Manchester University’s Sarah Haigh is an expert in nanotechnology - the science of manipulating atoms in matter - and says, it could make waste water from toilets safe to drink.
Sarah Haigh is working on a device which will turn toilet waste into fuel - and drinking water
The innovation - which has been funded
by billionaire Bill Gates - could transform the lives of millions of
people in the third world.
Haigh believes a new range of materials could extract energy from human waste.
Although
the result may not be bottled mineral water, the researcher says the
results could be the difference between life-and-death in regions
without clean water.
She said: ‘I get a lot of comments about the research I do. I don’t mind people making jokes as long as they’re clean ones.
‘There
has been a lot of research into biofuels. There is a lot of energy
already present in human waste. Nano-scale materials mean that you can
harvest the hydrogen and turn it into hydrozene - which is basically
rocket fuel.
The expert, from Manchester University’s
school of materials, 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.

Dr
Haigh, who working with scientists at Imperial College London and Durham
University, was given an initial $100,000 (£63,000) from the Bill and
Melinda Gates Foundation
Their
idea for an inexpensive fuel-producing, water-cleaning device for the
developing world, beat more than 2,000 other proposals.
And
the group stand to receive a further $1m from the Gates next year if
they can demonstrate the chemical reactions they propose can actually
work.
The Microsoft founder - one of the world’s richest men - has promised to sink his fortune on combating worldwide poverty.
The researchers plan to have a prototype ready to demonstrate by 2013.
Dr Haigh said: ‘The phrase ‘off to spend a penny’ is used in polite society to refer to a visit to the lavatory.

We
plan to turn this essential everyday outgoing into an investment by
developing novel materials that convert natural waste into a useable
resource.
‘This
technology will be particularly important for remote locations in
developing countries and will have the added benefits of reduced
pollution and lower waste disposal costs,’ she said.
