Fog project boosts water supply

The system is simple in design andconcept, but extremely effective.(Image: Unisa) MEDIA CONTACTS • Doreen GoughUnisa media manager+27 12 352 4150 or +27 82 497 7938Janine ErasmusA climatologist from the University of South Africa (Unisa) has helped develop a system to harvest moisture from abundant mountain fog in a water-scarce region of the Eastern Cape, and communities there are already benefiting from it.The project was successfully launched in Cabazane Village, in the rural Mount Ayliff area in the north of the province, in mid-March 2010 during the annual National Water Week.The area, which falls in the picturesque Alfred Nzo district municipality, is bordered to the north by the mountain kingdom of Lesotho and much of the terrain is steep and remote, with very cold winters and mild summers. Fog is a frequent visitor and a ready source of clean water.Fog specialistProfessor Jana Olivier of Unisa’s School of Agriculture and Environmental Sciences has spent the past 20 years specialising in the properties and hazards associated with fog, especially for vehicles.She later delved into the technique of fog harvesting. “We got funding from the Water Research Commission, and we designed the fog water system,” she said.Olivier teamed up with Professors Johan van Heerden, Hannes Rautenbach and Tinus Truter – all of Pretoria University – in the development of the system.Unisa is involved in ongoing research into water harvesting from fog, especially for isolated rural communities, where water is scarce and villagers often have to walk vast distances to fetch a few litres at a time.However, the system is only practical where fog occurs for at least 40 days a year, and for a period of several hours at a time.The project has also been rolled out in other dry areas of South Africa, including Venda, Limpopo, and the West Coast, but Mount Ayliff’s persistent fog yields the best results, producing hundreds of litres of water a day.“The West Coast and the mountainous areas – stretching from the Soutpansberg in the north, along the Drakensberg in the east to the Cape Mountains in the south – have the highest fog harvesting potential,” said Olivier.Eco-friendlyMount Ayliff is located in the Umzimvubu local municipality, one of two municipalities within Alfred Nzo – the other is Umzimkhulu. Umzimvubu’s population is just 198 550, of which only 4% live in towns – the rest live in rural areas.Safe drinking water is a continual problem as the area lacks essential infrastructure, including water on tap. Villagers are often forced to dip into natural springs, running the risk of picking up water-borne disease.“We have a challenge … because about 40% of our community here does not have basic water,” said Alfred Nzo mayor Gcinikhaya Mpumza.However, the villagers’ lives have changed with the installation of the water-harvesting system and its inexhaustible supply. No electricity is needed to power the scheme, which makes it eco-friendly and low-cost, and suitable for areas with no power infrastructure.Because the technology is simple, the equipment does not need special maintenance. The system consists of a double layer of 30% shade cloth nets stretched between steel cables supported by posts, with a gutter beneath each screen to catch the run-off. All components are readily available in the area.The Cabazane set-up involves around 700 square metres of netting, said Olivier, with each square metre of shade cloth yielding up to five litres of water a day – depending on the weather.Water droplets in the fog are trapped on the nets. They get bigger and heavier as the fog rolls along, and eventually run down into the gutter and from there through a filter into storage tanks. The system works best when the wind is blowing, because the fog moves over the nets more rapidly.The system is installed up on the mountain slope, where nothing more than gravity is needed to get the drops flowing into the tanks. Reports say that about 30 homes in Cabazane Village have already benefited from the project.The quality of water is described as “very high”, falling within the World Health Organisation’s standards for potable water. “The water is incredibly pure because it comes from the clouds,” said Olivier.Innovative schemes like the simple and cost-effective fog harvester are well-suited to South Africa, as it’s one of the driest countries in the world, with annual rainfall well below the global average.last_img read more

@eJosephSnowden Is Not Edward Snowden—But Who’s Behind The Account?

first_imgThe Dos and Don’ts of Brand Awareness Videos One of the world’s most wanted men is on the lam … and tweeting about it. At least that is what one satirist would have us believe.Various influential types in the digital-privacy space have declared @eJosephSnowden a fake—including Guardian journalist Glenn Greenwald, who won Snowden’s trust and broke the PRISM story last month. Yet the satirical account has 20,000-plus followers, which suggests it still fooling the masses.Journalists, teachers, authors, celebrities like Adam Baldwin and Roseanne Barr, and even John McAfee have tweeted at the handle as if it is real. (Twitter’s interface, which suggests accounts based on name matches without prompting a closer look at mentioned accounts, may be at least partly at fault here.)The Verge law and privacy journalist Matt Stroud follows the account, as does esteemed law professor Lawrence Lessig. To be fair, they may be curious or entertained, rather than duped. The account does tweet news and opinion someone like Snowden would share, which is done by design. Other tweets, however, are clearly inflammatory. Take this tweet from last week, for example:  That was likely a piece of Swiftian satire, meant to mock critical coverage of Greenwald, Bradley Manning, and WikiLeaks figure Julian Assange. Yet it managed to fool and anger a few people, including one woman in Canada who took issue with it: So who is @EJosephSnowden?The account is actually controlled by a writer at the Internet Chronicle, a site which mixes the obscene satire like Encyclopedia Dramatica with the fake-news coverage of The Onion to cover topics of interest to hackers and Internet-rights activists.Going by the name “Ed Snowden,” in a blog post last month about the twitter account titled “SNOW JOB: Being Edward Snowden,” the account holder writes that he was inspired by the “too-impulsive media environment” in creating the account. “Too-impulsive media environment” may be the wrong way to describe this Twitter fascination.“To anyone who understood the implications of Snowden’s claims, the very existence of a Twitter account at all should have seemed impossible and thereby ironic,” writes Ed Snowden, who describes the tweets themselves as a “cartoonishly radical caricature of the e-dissident.”A case of people seeing what they want to see? Sure.  But one detail doesn’t square with this version of events. The account has been tweeting since 2011, so if it’s a fake, it was one created long before Snowden leaked NSA documents and outed himself. The Twitter account used to operate under a different name and tweeted material related to the Internet Chronicle. That explains all the older tweets, pre-PRISM scandal, comprised almost entirely of links to articles on the satire site, like this one about Gawker writer Adrian Chen dying in a car crash.
