One of the key barriers in access to medical oxygen in developing countries is a stable source of clean power.  A team of researchers from Melbourse has come up with some creative and low-cost ways to producing oxygen from air.

“Where there is electricity, they build on existing oxygen concentrator technology by storing some of the oxygen locally at low pressure, ready to come instantly on line and ensure a steady supply whenever the electricity fails,” says a report published in the Guardian.

Concentrators work well for limited time in resource-poor settings, depending on the number of hours a health facility has electricity and how stable is that supply. The scientists have successfully found cost-effective ways to remove the nitrogen that makes up 78% of the air, leaving purified oxygen to go to the patient.

This team comprising theoretical and particle physicists and medical scientists from the University of Melbourne is likely to have solved a problem which kills 1.5 million children every year.
