Nano-scientists develop new kind of portable water purification system, could bring clean water to rural poor

Nano-scientists develop new kind of portable water purification system, could bring clean water to rural poor | "#Volunteer Abroad Information: Volunteering, Airlines, Countries, Pictures, Cultures" | Scoop.it

A water purification system that uses nanotechnology to remove bacteria, viruses and other contaminants may be able to deliver clean drinking water to rural communities for less than $3 a year per family, according to a new study.

 

Researchers at India's Institute of Technology Madras have developed a new kind of portable water purification system based on nanoparticle filtration. In their paper published in the Proceedings of the National Academy of Sciences, the team explains how their new device does its job—it employs nanoparticles to remove not just biological hazards, but toxic heavy metals as well. The system they have developed is a two-stage filtration process that provides 10 liters of clean water in just an hour's time.

Ghana: A Day in the Life of an A Broader View Volunteer (part 1) | Volunteer Abroad News

Ghana: A Day in the Life of an A Broader View Volunteer (part 1) | Volunteer Abroad News | "#Volunteer Abroad Information: Volunteering, Airlines, Countries, Pictures, Cultures" | Scoop.it

Several months ago, I had not heard of Kpando, Ghana. In fact, I would have had to search furiously on a map if you asked me to point to Ghana. A few months later, I awoke to a new dawn in the Volta Region of Africa and wondered what a 65-year-old retired lawyer was going to be able to contribute to the lives of the inhabitants of Kpando. The intuitive response was, “nothing. ”What skills does a former lawyer from the United States have that could make a positive impact in this rural town, far from the bustling streets of Accra?.....

Cellphones will replace cash in Africa

Cellphones will replace cash in Africa | "#Volunteer Abroad Information: Volunteering, Airlines, Countries, Pictures, Cultures" | Scoop.it

THE use of cellphones as an alternative means of payment to cash is set to rise significantly in coming years. This will be a major boost particularly for banks that are keen to penetrate the unbanked market.

 

KPMG said in a recent report that this new form of payment would have wide implications and benefits for developing economies. Its benefits would be transformational, particularly for developing economies, such as SA, which have large sections of their population who are either under- banked or unbanked.

 

SA has more than 11-million people without access to financial services, and the big four are promoting cellphone banking solutions to penetrate this market.

 

"In every market, mobile payments stand to take the place of cash," said KPGM in a report based on a recent global online survey of 970 companies.

 

The most successful cellphone venture launched so far in Africa is the M-Pesa service by Safaricom in partnership with its UK-based parent Vodafone. It was launched in March 2007 and now has more than 9,5-million subscribers using the service to make person-to-person money transfers. More: http://bit.ly/oZyWQ8

 ICT technology is used here by replacing cash payment trough digital payment with cellphones. This way people will have access to financial services and will be able to do their payments on a safe way.
