Desert Twins produce water through condensation in driest place on Earth

One in 10 people on Earth lack access to safe water , which is why artist Ap Verheggen has been working so hard to address water scarcity over the last decade or so. He and the rest of the SunGlacier team, invited by the Dutch Ministry of Defense, recently tested their idea of making water from thin air in what they describe as the driest, hottest place on the planet: the Sahara Desert . They were able to accomplish the feat solely with the power of the sun and a bit of basic physics. Take a closer look at their groundbreaking Desert Twins , designed specifically for this project, after the jump. From an ice-making leaf in the desert to a solar-powered desert waterfall , SunGlacier has pioneered creative, artistic approaches to the lack of water in Earth’s dry areas. They recently made water from air in Mali with the solar-powered Desert Twins, two devices built for the Sahara Desert test. One device makes water, the other houses an energy unit. Condensation enables the devices to create water.

According to the team, air in Mali on a summer day only has around half the water vapor of a dry summer day in the Netherlands. They faced several days of challenges as they tinkered with their devices, adding insulation and re-configuring cooling air streams before they finally succeeded in producing any water. The team knew their design could operate in ideal conditions, but the Mali success shows it can work just about anywhere in the world. SunGlacier says their device is “probably the world’s first artificial water well to work entirely off the grid .” SunGlacier intends to keep improving their technology, and say in the future they plan to focus on cleaning and enriching water with salts and minerals, and water storage. Their goal is to build a machine that is able to operate without electricity or a liquid water source, much like a well. + SunGlacier Via SunGlacier Images courtesy of SunGlacier

Earth’s population just hit 7.5 billion people

Comments Off on Earth’s population just hit 7.5 billion people

Over 7.5 billion people now reside on planet Earth , according to the World Population Clock . But with more people could comes less access to resources like food and energy . A global population of 7.5 billion people has far-reaching repercussions – including increased greenhouse gas emissions , strained food supplies, and increased total consumption, according to Charity organization Population Matters . Population Matters says that population growth could keep some countries in poverty , and it intrudes on land needed by wildlife . Head of Campaigns Alistair Currie told edie.net , “We will see cutthroat competition for shrinking resources which will include not just fossil fuels but productive land and water, pushing prices up not just for consumers but for the businesses and industries which need them too. Huge potential markets like much of sub-Saharan Africa will be stuck in poverty and we’ll see political instability arising from population and migration pressures, including conflict over resources.” China has the most people in one country; 1.38 billion people live there. India is next with 1.34 billion, followed by the United States with 326 million. The United Nations thinks our global population will hit 10 billion people by the year 2056. Related: Scientists say the world is “one crop breeding cycle away from starvation” Currie warned that while businesses may see increased global population as the opportunity to gain more customers, too much growth won’t be good for our planet – or business. He said, “Growth cannot continue indefinitely on a finite planet and fewer consumers is ultimately better for all of us. Business must start recognizing and adapting to that reality. With action now, we can limit population growth and eventually reach sustainable levels.” We’re currently using up the resources of 1.6 Earths , and we’ll need 3 Earths by 2050 unless we can alter our consumption patterns. + Population Matters Via edie Images via Stròlic Furlàn – Davide Gabino on Flickr and McKay Savage on Flickr

At least 60 dead in Ethiopian garbage "landslide"

Comments Off on At least 60 dead in Ethiopian garbage "landslide"

At least 60 people are dead after a mountain of trash collapsed at a dump in Ethiopia on Saturday night. The “landslide” at Koshe Garbage Landfill, which lies just outside the country’s capital of Addis Ababa, claimed mostly women and children, according to officials . With dozens still reportedly still missing, the final death toll could be even higher, they added. Around 150 people were present when the landslide occurred, a resident told the Associated Press . Several makeshift houses, inhabited by some of the landfill’s permanent residents, are now submerged under tons of refuse. Many of those who live at the 50-year-old landfill are scavengers who sort through the dross for items to sell. Others are there because it’s all they can afford. “My mother and three of my sisters were there when the landslide happened. Now I don’t know the fate of all of them.” Tebeju Asres, who lived at the site, told AP. Koshe, which means “dirty” in the local Amharic language, has experienced smaller collapses that killed two or three people, but nothing on this scale. Related: Ethiopia announces plans to build massive 1000MW geothermal power plant About 300,000 tons of waste from the capital’s 4 million people are deposited every year at Koshe, officials say. The city has been working to turn the garbage into a source of clean energy since 2013, when it began construction on what will be Africa’s first waste-to-energy plant when completed. The Koshe waste-to-energy center, which has $120 million invested in it, is expected to generate 50 megawatts of electricity. “In the long run, we will conduct a resettling program to relocate people who live in and around the landfill,” Diriba Kuma, mayor of Addis Ababa, told AP.

Global temperatures hit record high for the third year in a row

Comments Off on Global temperatures hit record high for the third year in a row

On Wednesday, National Oceanic and Atmospheric Administration scientists marked a disturbing new milestone in Earth’s history: 2016 has been officially declared the warmest year on record . The previous record was set in 2015 , which beat record highs in 2014 . That means that for three years in a row, global temperatures have continued to soar to unprecedented highs unlike anything we’ve seen in the modern era. Part of the record-busting temperatures in 2015 and 2016 could be attributed to an unusually warm El Niño , however, without the ongoing release of greenhouse gasses into the air, even the recent weather phenomenon couldn’t have made such a strong impact. Deke Arndt, chief of global climate monitoring for NOAA, told the New York Times , “A single warm year is something of a curiosity. It’s really the trend, and the fact that we’re punching at the ceiling every year now, that is the real indicator that we’re undergoing big changes.” Related: Record-breaking CO2 levels mark a “new era” in the world’s climate Some of the most extreme temperatures were seen in the Arctic, with ocean temperatures rising 20 to 30 degrees above normal. In fact, the climate was so unusual that enough Arctic ice melted to let a luxury cruise ship cross the Northwest Passage for the first time ever. Nature photographers captured horrifying images of polar bears stranded on dry earth with no snow or ice in sight. Devastating drought also hit Africa and India, with the town of Phalodi experiencing the hottest day in recorded Indian history at 123.8 degrees. With El Niño over, scientists are expecting 2017 to be a cooler year than those that have come recently. However, that doesn’t mean climate change is not still a concern. In fact, some worry that climate change could accelerate quickly in the coming years. The temperature burst between 2013 and 2016 – about half a degree globally in total – was the largest change in a three year period measured on the planet’s surface since 1880.
