Life saving science by very human scientists
Greater than Einstein
Even
after his death last month, Norman Borlaug's remarkable lifetime efforts to feed
millions of less fortunate around the world continue to inspire all those concerned
with the misery of starvation. As the father of the "Green Revolution",
he is credited with saving far more lives than any other person who has ever lived.
His agricultural techniques have been adapted around the globe and he was honored
with the 1970 Nobel Peace Prize for his achievements. Now, a British researcher
is claimed to be the next Borlaug. To grapple with the worldwide clean water problem,
Michael Pritchard has come up with a masterpiece of innovation in science: the
Lifesaver bottle
By LUAN GALANI (luan.galani@wavemagazine.net) from
Curitiba, BRAZIL The "Green Revolution" that has
fed much of the world, would never have happened save for the sheer force of will
exerted by the American agricultural scientist Norman
Borlaug (March 25, 1914 - September 12, 2009). Through his
scientific breakthroughs, he developed a strain of wheat that saved upwards of
one billion people from famine and starvation. "We made this choice in the
hope that bread being provided, also peace will be brought to the world",
said the Nobel Committee Chairwoman, Aase Lionaes, presenting the Nobel Peace
Prize to Borlaug in 1970.
For the past twenty-seven years, he has collaborated
with Mexican scientists on problems of wheat improvement and has also collaborated
with scientists from other parts of the world, especially from India and Pakistan,
in adapting the new wheats to new lands and in gaining acceptance for their production.
Thanks to him, food production doubled between 1960 and 1990, and starvation has
been kept at bay for millions of people in third world countries.
In
his own words, it was "a temporary success in man's war against hunger and
deprivation", a breathing space to deal with the "Population Monster"
and the subsequent environmental and social ills that too often lead to conflict
among men and nations.
A truly revolution
From Surrey, in
the UK, a man that has sold Apple computers for ten years is today rumored to
be the second Borlaug. This very same man is Michael Pritchard and he came up
with by far the most important invention in many decades: the Lifesaver bottle.
Pritchard
says the Lifesaver is very 'simple'. "You simply immerse the bottle in the
water, close it, give a few pumps and then that is all it is necessary. When the
cover is removed, clean water will get out", he explains. At
this lecture, during TED 2009 (Technology, Entertainment, Design: Ideas worth
spreading), he gives a great demonstration of his creation.
He
developed lifesaver bottle after seeing the tragic waste of life and serious problems
caused by the lack of safe drinking water in the wake of the Tsunami in December
2004, the following year when Hurricane Katrina hit Louisiana and more recently
the flooding in the UK. Unsatisfied with his feeling of impotence in the face
of a multitude of refugees obliged to wait for days on end to clean water, Pritchard
decided to do something about. And so, the Lifesaver appeared: a bottle capable
of transforming into clean water any sort of water.
Pritchard's
worries have basis. According to the UN, more than half of the world population
is going to suffer from the shortage of water in 2025. However, Lifesaver bottle
will have a significant impact on humanitarian and disaster relief operations.
Its unique technology means local sources of water may be safely drunk. Importantly
the Pritchard's bottle will reduce the spread of diseases and reduce the logistical
support required when responding to events.
Moreover, it lowers the overall
cost of response as in many cases no bottled water will be required. Less medicine,
staff and transportation are needed and no landfill sites have to be created to
dispose of the millions of waste plastic bottles. In future, deploying Lifesaver
bottles to emergency situations will result in more lives being saved at less
cost and with a faster response than has ever been possible before.
That
said, even armies are possible to use the bottle, as many have already pointed
out. The Lifesaver was recently voted 'Best Technological Development for Future
Soldier System Enhancement' by Soldier
Technology, the world's premier soldier modernization forum. One thing
is also certain: Lifesaver bottle will revolutionize the battle space, reduce
carried weight for the soldier, and lessen the traditional logistical demands
of drinking water faced by militaries around the world, as defends Mark Richter,
Programme Manager of Marine Corps Systems Command.
How does it work?
It
took a little while and some very frustrating prototypes in his kitchen. But,
eventually, he did it. Pritchard's bottle removes bacteria, viruses, cysts, parasites,
fungi and all other microbiological waterborne pathogens without using chemicals.
Likewise iodine or chlorine which leave a distinctive foul taste.
With
its 6000 litres capacity, Pritchard tells that before the Lifesaver, the best
portable filters were capable of filtering particles up to 200 nanometers (nm).
The problem, according to him, is that the smallest bacterium reaches 200 nm and
the smallest virus, 25 nm. "They will pass free and easily through the 200
nm pore. The Lifesaver pore has 15 nm. So, nothing can pass through them",
recalls the filter creator.
