One of the world's richest men has taken a close
interest in one of man's most basic functions: visiting the toilet.Bill Gates’ charitable organization, the Bill and
Melinda Gates Foundation, is looking for inventors to design the loo of the
future, which, they hope, would improve sanitation for millions of people
around the world.
So, what's wrong with the traditional flush toilet?
Firstly, it wastes a huge amount of potential drinking water.Secondly, they are more likely to cause pollution.This is a real problem in many areas of the developing
world, where, according to United Nations’ estimates, unsafe sanitation causes
half of all hospitalizations.Younger people are
particularly at risk.Illnesses which cause diarrhea are
responsible for the deaths of about 1.5 million
children a year.Finally, standard lavatories simply aren't
practical in remote areas.
The challenge set by Bill Gates was to come up with a latrine
which works without running water, electricity or aseptic tank.It also needed to operate for less than 5 cents.28 designs were displayed at the recent event of the
Toilet Fair in Seattle, USA.Among them was one which
turned human waste into electricity using microwaves, another which converted
human waste into charcoal, and yet another which used urine for flushing.
But the winner was a solar-powered design which
generated hydrogen gas and electricity.The team from
the California Institute of Technology(CIT)picked up a prize of $ 100,000.
But clearly Bill Gates doesn't feel he's flushing
money down the toilet.After the Seattle event he said, "We
couldn't be happier with the response we've gotten," Gates has even
promised $370 million more to the future toilet project.They hope to field test more prototypes over the next
three years.
