Girls In Kenya Use Vapor Technology To Quench Their Thirsts

Community members, having seen the devices in use at the school, hope to acquire some of their own if they can find the funding.

In this arid part of northern Kenya, water can be hard to find, particularly in the dry season.

But a center run by the Samburu Girls Foundation – which rescues girls facing early marriage and female genital mutilation – has a new high-tech source of it.

Since June, the center, which has rescued more than 1,200 girls, has used panels that catch water vapor in the air and condense it to supply their drinking water.

“We used to have difficulties in accessing water and during a drought we could either go to the river to fetch water or ask our neighbors to give us water,” said Jecinta Lerle, a pupil and vice president of students at the center’s school.

But now, officials at the school say, the girls no longer have to travel for water – including into communities they have left, which could put them at risk.

“The girls can now have more time to study since there is enough fresh water to go round and there is no need to walk long distances to search for water,” said Lotan Salapei, the foundation’s head of partnerships.

Girls formerly trekked up to five kilometers a day in search of clean water during particularly dry periods, sometimes bringing them into contact with members of their former community, Salapei said.

The center, given 40 of the water vapor-condensing panels by the company that builds them, now creates about 400 liters of clean water each day, enough to provide all the drinking water the center needs.

The “hydropanels,” produced by U.S.-based technology company Zero Mass Water, pull water vapor from the air and condense it into a reservoir.

Cody Friesen, Zero Mass Water’s founder and chief executive officer, said the company’s project with the Samburu Girls Foundation was an example of its efforts to make sure the technology “is accessible to people across the socioeconomic spectrum.”

The panels provided to the Samburu Girls Foundation cost about $1,500 each, foundation officials said.

Zero Mass Water has so far sold or donated the panels in 16 countries, including South Africa.

Saving trees

George Sirro, a solar engineer with Solatrend Ltd., a Nairobi-based solar equipment company, said such devices can be a huge help not only to people but in slowing deforestation that is driving climate change and worsening drought in Kenya.

Often people with inadequate water cut trees to boil the water they do find to make it safe, he said, driving deforestation.

Philip Lerno a senior chief in Loosuk, where the girls’ foundation is located, said he hopes to see the panels more widely used in the surrounding community, which usually experiences long dry periods each year.

Rare Earth Metals in Smartphones Can Now Be Tracked

Extracting rare earths from the environment or from industrial samples, like waste water from mines or coal waste products, is generally very challenging and expensive.

Researchers have developed a new protein-based sensor that can detect lanthanides, the rare earth metals used in smartphones and other technologies, in a more efficient and cost-effective way.

The sensor changes its fluorescence when it binds to these metals, according to the study published online in the Journal of the American Chemical Society.

The protein undergoes a shape change when it binds to lanthanides, which is key for the sensor’s fluorescence to “turn on”, said the study.

“These elements are called rare earths, and they include chemical elements of atomic weight 57 to 71 on the periodic table,” Cotruvo added. Pixabay

To develop the sensor, the researchers from Pennsylvania State University in the US used a protein they recently described and subsequently used to explore the biology of bacteria that use lanthanides.

“Lanthanides are used in a variety of current technologies, including the screens and electronics of smartphones, batteries of electric cars, satellites, and lasers,” said Joseph Cotruvo, Assistant Professor at Penn State and senior author of the study.

Extracting rare earths from the environment or from industrial samples, like waste water from mines or coal waste products, is generally very challenging and expensive.

“We developed a protein-based sensor that can detect tiny amounts of lanthanides in a sample, letting us know if it’s worth investing resources to extract these important metals,” Cotruvo said. (IANS)
