Comments Off on Researchers successfully made a battery out of trash

If there’s one thing that abounds on planet Earth , it is man-made trash . Fortunately, researchers have developed a method of using discarded goods to create sodium-ion batteries. Made from recycled materials and safer than lithium variants, the battery is the latest step in renewable energy storage. To create batteries out of trash, the scientists accumulated rusty, recycled stainless steel mesh. Then, they used a potassium ferrocyanide solution — the same solution used in fertilizers and in wine production — to dissolve the ions out of the rust layer. Ions such as nickel and iron then bonded with other ions in the solution. This created a salt that clung to the mesh as scaffolded nanotubes that store and release potassium ions. As Engadget reports , “The movement of potassium ions allows for conductivity, which was boosted with an added coating of oxidized graphite.” Related: ‘Instantly rechargeable’ battery spells bad news for gas-guzzling cars More often than not, lithium batteries are used for renewable energy storage. However, the type of battery is expensive and exists in limited amounts. Additionally, lithium batteries have been known to explode. Not only are the new sodium-ion batteries safer, they boast a high capacity, discharge voltage, and cycle stability. Developing the battery was step one of testing the concept. Now that scientists have successfully created renewable energy from trash, the battery can be improved upon to maximize its potential. Via Engadget Images via Pixabay

Comments Off on Elegant Australian home shows the beauty and toughness of rammed earth

Rammed earth may be an ancient building material, but the modern homes that use compact earth are anything but old-fashioned. One such example is Robson Rak Architects and Interior Designers’ recently completed Layer House, a robust and elegant home in Victoria, Australia that keeps naturally cool with rammed earth walls. Made from local materials by local artisans, the rammed earth is paired with timber to create a beautiful palette that will last the test of time. Built to last generations, the large 470-square-meter Layer House was designed with an eye for detail and quality. The home derives its name from the intersecting zones and private vistas created from an asymmetrical layout that wraps around a series of courtyards . Rammed earth and timber are the two main building materials in the Layer House. The architects write: “The sand component of the rammed earth is locally sourced and built by local artisans. Rammed earth is a sustainable, honest, and efficient building material that requires no maintenance and ages gracefully. The timber will be allowed to grey off and age with time.” A few vibrant pops of color, such as the green tiled island bench and blue sofa, provide contrast to the pale color palette.

Energy efficiency is further improved with double glazed and thermally broken aluminum doors and windows. Louvers control the flow of cross ventilation, while hydronic heating is embedded into the concrete floors. + Robson Rak Architects and Interior Designers Via ArchDaily Images © Shannon McGrath

Oregon couple spends years building their net-zero ‘extreme green dream home’

Comments Off on Oregon couple spends years building their net-zero ‘extreme green dream home’

Some people may spend years designing their dream home, but one ambitious couple in Oregon has just spent years building their “extreme green dream home.” As beautiful as it is sustainable , the Desert Rain home by Tozer Design is a 2,236-square-foot net-zero structure that was designed to meet the Living Building Challenge’s green building criteria – the industry’s most stringent. The couple began to build their “conventional” dream home on the same 0.7 acre lot in 2008, but upon hearing about the Living Building Challenge in the fall of 2009, they made the painful decision to scrap their original plans and shoot for the challenge. The result is a beautiful estate made up of five buildings, including the main residence, a detached apartment, a second detached building that can be used as an office or guest space, and the home’s two garages. Related: California city could become the first Zero Net Energy city in the U.S. The new construction began by repurposing materials from two aging mill houses that were previously on the lot. In addition to salvaging the existing materials, the team went far and beyond in finding sustainable, locally-sourced materials for the new home. In addition to the recovered wood already salvaged, reclaimed wood and FSC-certified lumber were brought in from the surrounding region. Additional materials were also specially made for the home’s green construction , such as the exterior plaster, which is almost entirely made out of local clay, straw, and sand. To conserve energy and costs whenever possible, other materials were constructed by the team by ordering and crafting the materials onsite. For example, rather than purchasing the items separately, a large roll of steel was ordered and cut onsite to construct the roofing, eaves, and rain gutters. Desert Rain is a power house of sustainability as well as energy efficiency . The home uses three renewable energy systems , including a solar array on the rooftop, a solar thermal drainage system that heats water and powers the hydronic floor system, and an innovative solar “hot air” system that is used to evaporate liquid from the home’s composting system. Given that the home is located in the arid high-desert region of Eastern Oregon, where the climate is dry and annual rainfall scarce, water conservation can be complicated for any homeowner. This made achieving the Net Zero Water criteria of the project a complicated task. However, using the unique layout of the five buildings, a rainwater collection system was conceived using the standing seam metal roofs to route rainwater through downspouts to the ground-level gravel filters to be used in the landscaping, which features mainly native plantings. + Tozer Design Via Living Future Photography by Chandler Photography

Comments Off on World’s first ‘cranehouse’ hoisted over Bristol harbor is completely carbon neutral

Could a new urban vacation trend take the trees out of treehouses ? The world’s first “cranehouse” has opened in Bristol and it’s every bit as spectacular as their conventional trunk-supported counterparts. Designed by vacation specialists Canopy & Stars , the tiny structure is hoisted by a cargo crane 26 feet over Bristol Harbor. What’s more, the low-impact wooden structure is completely carbon neutral, and it was built using sustainable materials . The “hanging basket” is a collaboration between Canopy & Stars and DIY company, B&Q, who decorated the space with a chic collection of sustainable furnishings. Touches of nature are found throughout the space, including walls inlaid with tree branches, a watering can shower, and a bed made out of a reclaimed tree trunk . Industrial hints such as copper finials, polished concrete, and natural vegetable-fiber mats complete the rustic, yet sophisticated interior design. Related: 9 treehouses you can actually rent for an off-the-ground getaway Along with a “living painting” by local artist Anthony Garrett, the design focused on creating a similar “multi-sensory experience” one might experience in a true treehouse. Scents of woodlands such as lavender, sage, and bark waft through the interior. Wild flowers are planted in recycled wooden crates on the exterior of the house and various pollinators were planted on the roof to attract bees and butterflies. Guests at Crane 29 will be able to enjoy the beautiful off-grid retreat by spending their time swinging in the indoor hammock and taking in the spectacular panoramic views of the harbor. Reservations, which run £185 a night, include a gourmet breakfast basket delivered to the house in the morning. Tom Dixon, managing director of Canopy & Stars, explains that the project was a labor of love for the company, “It’s taken three years of planning and design, and only three weeks of building, but we got there. What started as a dream has now become a reality,” said “We hope people enjoy their stays in this amazing building and wake up to the great outdoors feeling they are truly part of this pocket of nature in the city – a real natural high.” Crane 29 will only be opened to guests for just 100 days, but all of the profits from the rental space will be donated to the environmental organization, Friends of the Earth . + Canopy & Stars Via Telegraph Images via Canopy & Stars

Comments Off on Hyundai’s new emissions-free bus travels 180 miles on just one hour of charging

It isn’t just passenger vehicles  going green  these days – mass transit is jumping on the zero-emissions bandwagon. Hyundai just unveiled its first mass-produced electric bus called the Elec City . After one hour of charging, the bus can travel 180 miles thanks to a 256kWh battery pack. Best of all, the company’s first emissions-free vehicle will be available for order in 2018. According to a report from Yonhap news agency , the company has embraced green innovation “to diversify its lineup with environmentally friendly vehicles and enhance its brand image in global markets where clean modes of transportation have emerged a key point in auto manufacturing.” Hyundai launched the bus at the Truck & Bus Mega Fair, a local commercial vehicle exhibition. Tak Yeong-duck, senior vice president of Hyundai’s Commercial Vehicle R&D Division, admits that the Elec Bus has its flaws, but says it will undoubtedly become more efficient as  electric vehicle technology is improved upon. He said, “There still remain things to be improved in terms of the charging infrastructure for pure electric vehicles. But we have decided to launch the Elec City next year as the government plans to increase the number of charging stations in the coming years.” Related: The world’s fastest charging electric bus powers up in 10 seconds flat The sleek electric bus is estimated to cost more than 200 million won ($179,000 USD), and that price does not factor in the central government’s subsidy worth 100 million won. It has not been confirmed, either, if the company will sell the Elec City (which took eight years to develop) in the United States. If Hyundai does make the emission-free bus available in the U.S., it will face some fierce competition. Chinese manufacturer BYD has sold electric buses in California , as has the Canadian company GreenPower . Tesla CEO Elon Musk has also considered developing an electric bus and knowing his ambition, it might just happen. Now that Hyundai has unveiled its first emissions-free vehicle, it has a new goal of improving the fuel efficiency of its commercial vehicles up to 30 percent by 2020. Additionally, the company aims to sell 105,000 commercial vehicles in global markets, up from 102,000 units sold in 2016. According to recent reports, Hyundai may even release a long-range electric vehicle in 2018 – keep an eye out for that. + Elec City Via Yonhap News Agency Images via Elec City
