Comments Off on The companies storing energy in cold air

Renewable sources of energy are getting more efficient by the day – yet energy storage remains an obstacle standing in the way of wide adoption. To fill this gap, some companies are thinking outside the box and investing in developing energy storage that relies on cold air. “Compressed air is an interesting technology,” Ravi Manghani, director of energy storage at Greentech Media told the BBC . “It can be a form of bulk storage.” Alacaes in Switzerland is one company that has explored cold air energy storage by drilling a hole in the side of the mountain, in which compressed cold air is stored until needed to drive a turbine. Read on to learn more about this and other efforts to hold energy in cold air. Alcaes’s mountain drilling technique may prove effective, though it is limited in its applications. “The downside is it has to rely on specific geological formations… It needs underground caverns which in itself is a limitation,” said Manghani. The United Kingdom-based Highview Power Storage is pioneering an alternative method for cold air energy storage by using refrigeration to cool air to -196 degrees Celsius, at which point air becomes liquid. This liquid air is then held in low pressure environments until it is needed. Related: New rooftop cooling tech beams excess heat into outer space Highview has constructed a facility near Manchester that uses heat generated by burning waste gas from a landfill to expand liquid nitrogen in the stored air. The expanded air is then channeled through a turbine, which generates electricity. Highview expects this facility to be connected to the UK energy grid in spring 2018. Highview hopes their facility will serve as a model for a planet that desperately needs clean energy storage solutions. “Globally the world is realizing that true grid scale, long duration storage is a requirement if we’re to go for a decarbonised future,” Stuart Nelmes, Highview’s engineering director, told the BBC , “and this tech will play a key part in that.” Via BBC Images via Gasworld and Highview Power Storage

A devastating garbage landslide precipitated by heavy rainfall wounded six people and killed 16 in Maputo, Mozambique , The Guardian reported . The 42-acre Hulene dump — located in the impoverished neighborhood of Hulene — rises nearly 50 feet above residents who live around the edges, and the avalanche consumed over 10 homes. Local Paulina Cosa told The Guardian, “It was late and the rain was pouring down, but I was woken up by something that sounded like an explosion.” Hulene dump collapse: Sixteen people confirmed dead – #Mozambique civil protection https://t.co/2h9vnyX45T #SADC #Africa pic.twitter.com/b26ecZouGd — Club of Mozambique (@clubOmozambique) February 20, 2018 People who live near the Hulene dump and earn money salvaging trash are exposed to stench, mosquitoes, and disease. Life isn’t easy, and 16 people lost their lives when rains triggered an avalanche around 3 AM one morning last week. The rubbish swallowed around 328 feet of land, consuming houses and killing people.

Recovery operations are over now as earth-moving equipment shoves back heaps of trash. Mucavele told The Guardian, “We are now working to return the waste to where it came from. The people who were living here will be given help, but no one can live here from now on.” Residents at the collapse site were moved to a temporary shelter around 30 minutes away. Authorities believe more bodies could be buried at the Hulene garbage dump on the outskirts of Maputo, and a search was underway. https://t.co/0ggbX9kJs1 pic.twitter.com/osRmrCUdFQ — All4Women.co.za (@all4women) February 20, 2018 Some people have called for the resignation of mayor David Simango, who campaigned for re-election in 2013 with the promise to shut down the dump. Livaningo , a local environmental activism organization, has been trying to get the dump closed for 15 years. They say it’s operating way above capacity and creating hazardous living conditions. Activist Manuel Cardoso said they’ve been telling the government such an event like this one would happen for years, telling The Guardian, “What we are looking for now is how we can help these families find justice. Where is the responsibility of the government?” Eight people were buried in a state-sponsored funeral last week. Maputo City governor Iolanda Cintura said in a speech, “On behalf of the government, in my own name we apologize to the Uamusse, Ngovene, Thousene, Mondlane, and Bendene families for what happened. We expect everybody to help all these families to recover their hope.” Via The Guardian Image via Depositphotos

Comments Off on This rustic Norwegian cabin looks like four different buildings all joined together

This rustic cottage in Norway looks like a patchwork of different buildings, all mashed together to create a cohesive home. The building, designed by Oslo-based studio Rever & Drage Architects , comprises a sequence of distinct spaces, each one addressing a different daily need of the owners. The cabin has a transparent garage that acts as an entry point and storage area where the family can leave their gear for various outdoor activities. This space leads to a laundry area, bathroom, and kitchen and into the main lounge that offers views of the surrounding landscape. Related: Coastal cabin in Norway is a perfect indoor retreat for outdoor lovers Each of the spaces uses different cladding materials and construction techniques, with the imperative of being able to withstand the harsh weather as an overarching design principle. The cabin, in a way, can be seen as a single building or four separate structures. “The outside composition is that of a traditional row farm, where buildings with different functions and different construction techniques are arranged in a line corresponding with the dominant direction of wind,” explained the architects. Related: Fantastic Norway’s Mountain Hill Cabin is Part Ski Slope, Part Winter Retreat While the north part was built using a late-medieval building technique with large, narrowing logs, the living room features more elegant 19th century notched logs, all stained in a dark tar finish. The kitchen has a contemporary feel, with a green roof. The garage, at the southern end of the building, features an exposed timber frame and polycarbonate sheets to let in tons of light all year long. + Rever & Drage Architects Via Dezeen Photos by Tom Auger

Comments Off on Montana judge stops massive coal mine expansion, citing climate impact

In another strike against coal, a federal judge just shut down plans for a large coal mine expansion in Montana, saying US officials had exaggerated the economic benefits of the mine while downplaying the impact it would have on the environment. Signal Peak Energy wanted to expand the Bull Mountain coal mine by 11 square miles and 176 million tons, claiming it would create jobs and generate tax revenue, all while not having any new impact on climate change . U.S. District Judge Donald Molloy blocked the proposal, ruling that approving such a request should take into consideration not just the environmental effects of the mine, but shipping the fuel to Asia and the carbon cost for climate chang e of burning that fuel. The ruling has its roots in a lawsuit filed in 2015 by the Sierra Club, Montana Elders for a Livable tomorrow and the Montana Environmental Information Center, in which the groups stated that the government has not considered the effects of mining once it leaves the mountain. Related: Global coal production falls 6.2% in the biggest decline in history Mine owners argued the expansion would add $24 million in tax revenue and that there would be no additional impact to the environment, since customers could simply go elsewhere for more coal anyway. “This conclusion is illogical, and places the (Interior Department’s) thumb on the scale by inflating the benefits of the action while minimizing its impacts,” wrote Judge Molloy. Similar rulings in Colorado and Montana have been made in the past, but in those cases, mines were eventually allowed to expand after further environmental review.

Fixing Earth’s ozone layer has other surprising benefits, new study shows

Comments Off on Fixing Earth’s ozone layer has other surprising benefits, new study shows

Dozens of nations signed an agreement nearly 30 years ago to stop the expansion of a massive hole in Earth’s ozone layer. Today, thanks to the Montreal Protocol, the hole in the ozone layer has shrunk as countries reduced, then eliminated, the use of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). A new study from  Geophysical Research Letters  now shows that the agreement not only achieved its stated aim, but has also been one of the most effective tools for fighting climate change in the United States. The recent study confirms what scientists and policymakers have been observing as the Montreal Protocol was enacted, though it focuses primarily on the United States. “This is something that’s been talked about for a while, this dual benefit of the Montreal Protocol limiting damage to the ozone layer, also curtailing climate change,” said Rachel Cleetus, climate policy manager and lead economist with the Climate and Energy program at the Union of Concerned Scientists. “It’s because all these ozone depleting substances are also very potent global warming gases.” The regulations enacted to fulfill the Montreal Protocol resulted in greenhouse gas reductions equivalent to approximately half of all other climate regulations between 2008 and 2014. Related: Antarctic ozone layer shows “first fingerprints of healing” The near-total removal of CFCs and steep decline in HCFCs in the United States was made possible by the Clean Air Act , a law that was used by the Obama Administration , as approved by the Supreme Court in Massachusetts v. EPA, to reduce greenhouse gas emissions. Though CFCs and HCFCs have been replaced by hydroflourocarabons (HFCs), which still contribute to climate change but do not burn a hole in the ozone layer, the signatories to the Montreal Protocol have amended the agreement to reduce HFCs as well in a move that was praised by US Secretary of State John Kerry as the “single most important step” in combating climate change. As the Trump Administration refuses to fulfill its duties under the Clean Air Act to protect public health, the success of the Montreal Protocol is a hopeful reminder of what can be done if dedicated parties work together and take action.

Comments Off on Swiss grocery store chain will be the first to sell insect burgers

Would you eat a burger made of mealworms? Coop , the second-largest supermarket chain in Switzerland , will start selling food made with insects . The country will be the first in Europe to allow sales of insect-based food for people, thanks to laws changed in May. Coop will sell insect burgers and balls from Switzerland-based startup Essento . Switzerland’s food safety laws allow sales of food made from mealworms, crickets , or grasshoppers. Coop will be selling Essento Insect Burgers and Essento Insect Balls, both made with mealworms. The burgers also contain rice, vegetables like leeks and celery, and spices like chili and oregano. The balls – which could be eaten inside pita bread, for example – are filled out with chickpeas, garlic, onions, parsley, and coriander. Related: BUG BUG cutlery set might just make you want to eat insects Coop Head of Category Management Silvio Baselgia said they’re Switzerland’s first retailer to sell Essento’s insect products, which the company has been developing for more than two years. Essento co-founder Christian Bärtsch said in a statement, “As food, insects are convincing in many respects: they have a high culinary potential, their production saves resources, and their nutritional profile is high quality. Thus insects are the perfect complement to a modern diet.” According to Essento’s website, mealworms don’t produce as many greenhouse gases as animal food sources like pigs or cows. 80 percent of insects are edible, as compared with 40 percent of cows, and raising insects requires less food and water. Insects are a good source of protein and also contain unsaturated fatty acids, the vitamins A, B, and B12, and minerals like zinc, potassium, calcium, and iron. Essento’s products will be on sale on August 21 in seven Coop stores to start, including branches in Zurich and Geneva. + Essento Via The Guardian and Coop Images via Essento Facebook and Coop

Comments Off on Spectacular ‘Dome of Visions’ greenhouse pushes the envelope for wood construction

Finnish company Metsä Wood is known for pushing the envelope when it comes to building with wood. Their latest greenhouse dome is the largest to date – and it showcases the company’s innovative use of laminated veneer lumber as a sustainable alternative to commonly used building materials. The structure, named Dome of Visions, was designed by Atelier Kristoffer Tejlgaard  as a way to explore green building. The Dome of Visions 3.0 is the third project in a series of experiments that explore the idea of creating sustainable spaces within dome-shaped structures. It has a new system of curved wooden beams , composed of 21 mm strips of Kerto LVL (Laminated Veneer Lumber). This made it possible to minimize the amount of steel while achieving both a sleek and elegant grid construction. Related: Architect designs life-sized replica of Empire State Building made of wood Using curved wooden beams, the brackets for the dome’s supports were cut as stars in a five-millimeter steel plate. The custom-made Kerto beams made it possible to avoid the use of complicated and costly welded brackets used in previous versions. Related: Mobile Greenhouse Studio Boasts a Facade of CNC-Cut “Fish Scales” in Copenhagen “Wood as a building material has obvious advantages giving sustainability for the building industry.

Handsome timber chalet shows off the beauty of modern minimalism

Comments Off on Handsome timber chalet shows off the beauty of modern minimalism

The charms of simplicity are celebrated in this beautiful timber chalet tucked in the Alps of eastern France. Designed by French architecture firm Studio Razavi , the recently completed Mountain House carefully sidesteps cookie-cutter design with its modern interpretation of the traditional alpine chalet. Located in the French village of Manigod in a popular ski destination, the Mountain House was subject to strict building codes that the architects say allowed for “very little freedom of architectural expression.” Local guidelines dictated numerous design aspects, including building height and width ratio, roof slope, building material , and even window sizes, in order to preserve the region’s traditional vernacular. The architects skillfully overcame these obstacles by studying the historical buildings and then producing a code compliant design that put a contemporary twist on the local architectural culture. The 200-square-meter Mountain House features the traditional three-story chalet layout with a pitched roof. Unlike its neighbors, however, the new holiday home sits on a lower level made of concrete rather than stone and doesn’t include the ornamental elements that adorn many of the homes in the valley. Related: Mind-bending mountain chalet looks as if it could tip over at any moment The Mountain Home only includes the essential features, making for a simple and utilitarian, yet beautiful design. Pine clads the first and second floor and untreated timber planks line the interior. A few painted surfaces and textures, such as the artificial stone tiles in the bathroom and dark carpet flooring, break up the largely timber palette. Large windows flood the home with natural light while several overhangs protect against harsh sun. + Studio Razavi Via Dezeen Images © Olivier Martin Gambier

Snhetta’s Norwegian Wild Reindeer Centre Pavilion was Inspired by the Robust Landscape

Comments Off on Snhetta’s Norwegian Wild Reindeer Centre Pavilion was Inspired by the Robust Landscape

Norway is perhaps best known for its coastal fjords , but the northern landscape has much to offer in its interior as well. Architecture firm Snøhetta took the opportunity to design a robust but low-impact building for visitors to immerse themselves in the Dovre Mountain plateau, home to musk oxen, arctic foxes and reindeer herds which roam amid a rich variety of plants and killer views. The pavilion is elemental in its use of a steel skin, glass walls and an extraordinary wood core which reads almost like a topographical map. The pavilion was commissioned by the Norwegian Wild Reindeer Foundation to allow visitors to behold the range of the reindeer. Snøhetta’s design for the center may have taken a cue from the Norwegian National Tourist Routes Project, which placed a series of Architectural refuges throughout the country. The pavilion is designed to withstand the harsh elements with a steel encasing protecting its wooden core. A bank of windows overlooks the Snøhetta Mountain from Tverrfjellet, a plateau at the elevation of 1,200 meters. The mythical landscape is reflected in part by a tremendous wooden wall inserted into the core of the pavilion. The robust organic quality of the wall was achieved by cutting large wooden beams on a CNC machine. The 25 cm square beams were then stacked and secured with wooden pegs to create the undulating effect. The wall looks as though it is deeply weathered, eroded by eons of wind and water. A bump out provides seating next to a suspended indoor fireplace, and the exterior has a similar seating arrangement. + Snøhetta Architects Via e-architect Photographs via  Snøhetta  and Klaas Van Ommeren

Old mountain retreat renovated into sublime off-grid refuge

Comments Off on Old mountain retreat renovated into sublime off-grid refuge

The challenges of renovating older buildings are already numerous, but when working deep in 8,100-foot-high mountainous topography and extreme climate conditions, it can be downright perilous. Meeting the challenge head-on, architecture firms Arteks Arquitectura and Ginjaume Arquitectura i Paissatge partnered up to convert a 1930s mountain retreat in the Andorran Pyrenees into the modern, off-grid Illa Mountain Hut that can generate up to four days of self-sufficient energy . Working within the confines of such harsh conditions, reforming the mountain refuge proved to be an uphill battle at every turn. The first hurdle was working under the restrictions imposed by the area’s protected UNESCO World Cultural Heritage status. Additionally, the extreme weather conditions meant that the project team could only access the site – the 4th highest shelter in the Pyrenees – during the summer months. Related: Modern lodge in the Rocky Mountains produces as much energy as it consumes Although the conditions were not optimal for building, it did have its advantages. Working around so many environmental barriers enabled the building team to use the restrictions to their advantage by using eco-friendly materials that were purpose-built for the project. Due to the harsh conditions and topography, for example, the architectural team chose to use light and prefabricated materials that could be flown in by helicopter. With most of the elements prefabricated in workshops and assembled on site, the building now weighs about a third of a similarly-sized conventional building and the execution time of the project was cut down to a surprising six months. Using the existing building as a structural base helped the team to further minimize the cost of the project as well as reduce the waste associated with the project. The wooden frame was reinforced with an extended gabled roof which helps discharge large snow loads during winter. This feature was also strategic to optimize solar energy gain . Thanks to a large array of photovoltaic panels installed on the roof, the refuge can generate up to four days of energy self sufficiency , making the project 100% off-grid. In addition to its solar power, the structure uses an independent water treatment system equipped with coconut filters . Additionally, an efficient ventilation system and ultra-thick insulation keeps the interior spaces warm and cozy, free from the extreme exterior cold. + Arteks Arquitectura + Ginjaume Arquitectura i Paissatge Photography via Pol Viladoms
