World's First Wave-Powered Buoy Turns Seawater Into Drinking Water

North Carolina-based startup EcoH2O Innovations has created the first-ever desalination buoy that only uses the power of waves to turn seawater into drinking water.


Engineers Justin Sonnett and Chris Matthews claim that a single Swell Actuated Reverse Osmosis System (SAROS) machine can clean 3,500 gallons of seawater a day. A grouping of 10-20 units can provide up to 50,000 gallons per site.

According to CityLab, the SAROS "draws in sea water, pumps it at high pressure through a reverse-osmosis membrane, and emits clean, drinkable water, which it stores in a tank until it's ready to be run back to shore."

Desalination plants are a potential solution for water scarcity but they have several problems—they require a large swath of land and city infrastructure, have a big brine discharge problem and also require fossil fuels to operate. The portable SAROS, however, can fit in the back of a truck only needs waves to run, making it relatively cost-effective and energy independent.

"SAROS is different because, by using it, we can cut the cost currently associated with producing fresh water in half," Matthews, SAROS director of research and development, told New Atlas.

The system was designed for the 230 million people living on island and coastal communities that lack access to potable water.

"Typical desalination processes can be taxing on the environment, especially coastal communities," the team said. "Unlike traditional methods that require a huge amount of power, typically generated by burning fuel oil, SAROS uses clean, renewable wave energy and produces zero emissions and minimal salt brine concentration."

Besides providing a constant source of clean water, the SAROS can help island nations curb their use of dirty energy. Many of these areas are bearing the brunt of climate change, from natural disasters to sea level rise.

"We're completely removing the dependency on electricity and fossil fuels, and creating one of the first environmentally conscious desalination systems that will allow us to bring affordable fresh water to coastal areas across the globe," the team added.

EcoH2O said the SAROS can one day be used to tackle other problems besides water scarcity.

"The innovative, wave-powered technology used in SAROS could also be configured to do things like generate electricity, autonomously pump water to clean up oil spills or even filter plastic from our ocean," the team said. "The amount of potential good that SAROS can bring is as exciting as it is endless."

Sonnett and Matthews came up with SAROS as their senior design project at the University of North Carolina at Charlotte in 2014. After graduating, they've picked up multiple awards for their concept, including the prestigious Thomas Edison Award in 2014 for dedication to sustainability.

The SAROS team has launched an Indiegogo crowdfunding campaign to raise the $25,000 they need to take this project above water. The cost per unit is expected to retail around $23,000.

Video Shows Oil Company's Plans to Drill Arctic From Artificial Island

The Liberty Project has posted a video about its proposal to build the nation's first oil production platform in federal waters in the Arctic.

The video was quietly uploaded two months ago and shows Hilcorp Alaska's plan to build an artificial gravel island and undersea pipeline for its offshore drilling project in the Beaufort Sea. Frankly speaking, the five-minute clip—with its all-American voiceover and electric guitar riffs—is something you'd expect from a pickup truck commercial.

Scientists Discover Sea Levels Rose in Sharp Bursts During Last Warming

By Rice University

Scientists from Rice University and Texas A&M University-Corpus Christi's Harte Research Institute for Gulf of Mexico Studies have discovered that Earth's sea level did not rise steadily but rather in sharp, punctuated bursts when the planet's glaciers melted during the period of global warming at the close of the last ice age. The researchers found fossil evidence in drowned reefs offshore Texas that showed sea level rose in several bursts ranging in length from a few decades to one century.

The findings appeared Wednesday in Nature Communications.

Quitting Coal: New Global Survey Names the Companies, Countries and Cities

More than a quarter of the 1,675 companies that owned or developed coal-fired power capacity since 2010 have entirely left the coal power business, according to new research from CoalSwarm and Greenpeace. This represents nearly 370 large coal-fired power plants—enough to power around six United Kingdoms—and equivalent to nearly half a trillion dollars in assets retired or not developed.

While many generating companies go through this rapid makeover, the research also shows that a total of 23 countries, states and cities will have either phased out coal-fired power plants or set a timeline to do so by 2030.

New Evidence Suggests Ancient Egypt Was Brought Down By Volcanoes and Climate Change

Ancient Egypt is often described as an exotic place—pyramids, hieroglyphics, lavishly worshipped kings and queens.

But in many ways, it has a lot of parallels to modern life. It was an economically diverse, culturally vibrant and unequal place.

The millenniums-old society also struggled with a phenomenon that people today know all too well: climate change. And it may have ultimately led to the civilization's demise, according to a new paper by a team of researchers at Yale University.

The team of researchers studied the tail-end of ancient Egypt during the Ptolemaic dynasty between 305-30 BCE.

Kids Harmed by Portugal Fires Reach Key Crowdfunding Goal for Climate Lawsuit

As Portugal reels from its worst wildfires on record, seven Portuguese children have met an important crowdfunding goal for their major climate lawsuit against 47 European nations.

More than £20,000 ($26,400) was pledged by 589 people, allowing the Global Legal Action Network (GLAN)—the nonprofit coordinating the lawsuit—to identify and compile evidence to present to the European Court of Human Rights in Strasbourg, France. GLAN now has a new stretch target of £100,000.

German Nature Reserves Have Lost More Than 75% of Flying Insects

A new study published Wednesday in the journal PLOS ONE adds more evidence that insect populations around the globe are in perilous decline.

For the study, researchers from Radboud University in the Netherlands, alongside their German and English colleagues, measured the biomass of trapped flying insects at 63 nature preserves in Germany since 1989. They were shocked to discover that the total biomass decreased dramatically over the 27 years of the study, with a seasonal decline of 76 percent and mid-summer decline of 82 percent, when insect numbers tend to peak.

Pushing Toxic Chemicals and Climate Denial: The Dark Money-Funded Independent Women’s Forum

By Stacy Malkan

The Independent Women's Forum is a 501(c)(3) nonprofit that has taken money from tobacco and oil companies, partners with Monsanto, defends toxic chemicals in food and consumer products, denies climate science and argues against laws that would curb the power of corporations.

IWF began in 1991 as an effort to defend now Supreme Court Justice (and former Monsanto attorney) Clarence Thomas as he faced sexual harassment charges. The group now says it seeks to "improve the lives of Americans by increasing the number of women who value free markets and personal liberty."

Toxic Toys? After Nine Years, a Ban on Harmful Chemicals Becomes Official

Phthalates are a particularly harmful type of chemical, used, among a range of other ways, to soften plastic in children's toys and products like pacifiers and teething rings. In response to mounting concern about the serious health impacts of phthalates—most notably, interference with hormone production and reproductive development in young children—Congress voted overwhelmingly in 2008 to outlaw the use of a few phthalates in these products and ordered the Consumer Product Safety Commission (CPSC) to assess the use of other types of the chemical in these products. After much delay, the CPSC voted 3–2 Wednesday to ban five additional types of phthalates in kids' toys and childcare products.
