Scientists used to make graphene -based membranes in small batches in a laboratory. But a new breakthrough at MIT enables researchers to roll out large sheets of high-quality graphene. The continuous manufacturing process can produce five centimeters of high-quality graphene per minute. The longest run was nearly four hours, and it generated around 10 meters of continuous graphene. MIT is calling the development “the first demonstration of an industrial, scalable method for manufacturing high-quality graphene that is tailored for use in membranes that filter a variety of molecules.” These membranes could be utilized in biological separation or desalination , for example. The researchers drew from the common industrial roll-to-roll approach blended with chemical vapor deposition, a common graphene-fabrication technique.

According to MIT, here’s how it works: “The first spool unfurls a long strip of copper foil, less than one centimeter wide. When it enters the furnace, the foil is fed through first one tube and then another, in a ‘split-zone’ design. While the foil rolls through the first tube, it heats up to a certain ideal temperature, at which point it is ready to roll through the second tube, where the scientists pump in a specified ratio of methane and hydrogen gas, which are deposited onto the heated foil to produce graphene.” MIT associate professor of mechanical engineering John Hart said, “In the end-to-end process, we would need to integrate more operations into the manufacturing line. For now, we’ve demonstrated that this process can be scaled up, and we hope this increases confidence and interest in graphene-based membrane technologies, and provides a pathway to commercialization.” The journal Applied Materials and Interfaces recently published the work; scientists from Vanderbilt University , the California Institute of Technology and the National University of Singapore contributed. + MIT News + Applied Materials and Interfaces Images via Christine Daniloff, MIT and courtesy of the researchers

A giant, air-purifying "cloud" just popped up in the middle of Milan

If you’re tired of breathing less-than-clean city air , Milan has a temporary respite for you. “Transitions,” a giant, cloud-like pod, has landed in the heart of the Brera Design District for Milan Design Week 2018 . As envisioned by Takehiro Ikeda, the enormous “water-drop pavilion” uses Panasonic ‘s cutting edge air-purifying technology to provide all those who enter with clean, cool air. Most cloud-like design installations create mist using gases, which aren’t exactly good for the visitors’ health. The Panasonic pavilion, however, employs only natural water to build an intangible and immersive experience: a walk through atmospheric, ultra-fine mist created with the company’s groundbreaking technology. Panasonic’s “Nanoe x” technology collects moisture from the air and uses high voltage to create nano-sized particles of water. Highly reactive components called OH radicals — which are generated in huge numbers and inhibit viruses and bacteria — remove odors and allergens and prevent mold. The pavilion utilizes compressed air to turn water into a “silky fine mist.” Unlike a conventional two-fluid nozzle model, this technology creates a fine mist using low-pressure air and eliminates the need for large compressors, making it an attractive option for city cooling technology. Takehiro Ikeda said the “Transition” installation is a preview of the latest air purification research, which will be used during the 2020 Olympics in Tokyo to guarantee a pleasant, cool atmosphere during the hot Japanese summer.

Instead of using large amounts of natural resources to power the air conditioning system, the pavilion – which measures about 20 meters in diameter – needs only a few liters of water for each functioning cycle. With this installation, Panasonic is celebrating its 100-year anniversary and transitioning towards a new creative philosophy: designing products, services and experiences that go beyond physical products to address emotional and environmental well-being. + Milan Design Week 2018 Images via Maria Novozhilova for Inhabitat

Filed under Eco, Green

It’s been a busy week for Hyperloop Transportation Technologies (HyperloopTT): they began building a test track in France , and now they’ve just announced the signing of an agreement with Aldar Properties , a Abu Dhabi real estate developer, for what HyperloopTT described as “the first commercial Hyperloop system in the UAE .” Hyperloop plans to start construction next year, with the first section open by 2020. ? Aldar Properties and HyperloopTT signed a memorandum of understanding for a commercial Hyperloop system, including a Hyperloop Visitor Center and HyperloopTT’s XO Square Innovation Center. This agreement will allow the California-based company to start building an around six-mile Hyperloop system. The site is near the border between Abu Dhabi and Dubai , near the Al Maktoum International Airport and the location for Expo 2020 . In fact, HyperloopTT chairman Bibop Gresta said with regulatory support, they aim to have the first Hyperloop section operational in time for the expo. Related: HyperloopTT is building the world’s third Hyperloop test track in France Aldar Properties CEO Talal Al Dhiyebi said in the statement, “We believe that Hyperloop technology can have a major positive impact on the lives of all those living within our communities, and we look forward to this possibility becoming a reality.” HyperloopTT said they would build the Hyperloop system in several phases, and although this agreement covers a six-mile system, they ultimately aim to construct a commercial network throughout the UAE. They said they’ve been working in the country since 2016, and have finished a comprehensive feasibility study, working with Abu Dhabi’s Department of Transportation. HyperloopTT CEO Dirk Ahlborn said, “With this historic agreement in Abu Dhabi, we take a big step towards the world’s first commercial system.” This isn’t the first time cities in the United Arab Emirates have shown an interest in Hyperloop technology; in 2016, Hyperloop One (now Virgin Hyperloop One ) signed an agreement with Dubai’s Roads and Transit Authority to evaluate a Hyperloop system in the area. Earlier this year, Virgin Hyperloop One and Dubai’s Roads and Transit Authority unveiled a commuter pod prototype . + Hyperloop Transportation Technologies + Aldar Properties Images via Hyperloop Transportation Technologies

Discovery of ancient middle finger bone completely upends what we know about human migration

Comments Off on Discovery of ancient middle finger bone completely upends what we know about human migration

Archaeologists have discovered an ancient middle finger bone in Saudia Arabia, and it could completely change what we know about human migration. An 85,000-year-old bone belonging to Homo sapiens marks the first evidence of humans that scientists have found in the Nefud Desert. This is also the first time Homo sapiens bones of that age have been discovered anywhere outside Africa. The current theory of human migration posits that Homo sapiens migrated en masse in a movement known as “Out of Africa” about 60,000 years ago in a single, contained wave. But this newly-discovered bone suggests that people migrated out of Africa in multiple different phases, at least 20,000 years earlier than we thought. Related: Incredible fossil discovery rewrites the history of human migration out of Africa Archaeologists unearthed the 1.25-inch middle finger bone in 2016, and researchers used a CT scan to form a 3D model of the entire bone, which showed conclusively that it belonged to Homo sapiens.  Nature  published news of the discovery this week. “What our discovery shows is that the early spread of Homo sapiens was much more spatially widespread than we thought,” said lead study author Huw Groucutt of the University of Oxford .

Comments Off on Over 100 cities around the globe run mostly on renewable energy

A new report shows that over 100 cities around the world are running on predominantly clean energy . That figure is up from just 40 in 2015, and it shows that more and more cities – from Seattle, Washington to Inje, South Korea – are ditching fossil fuels and turning to renewables than ever before. According to a report from CDP , more than 100 cities across the globe get 70% or more of their energy from wind, solar, hydro and biomass. Some cities are even getting 100% of their energy from renewable sources, like Burlington, Vermont, which became the first US city to move completely to renewables. 58 other cities in the US have joined the growing #WeAreStillIn movement and pledged to transition completely to renewables. Related: Burlington, Vermont Now Runs on 100% Renewable Energy At the same time, electricity demand is decreasing. Thanks to a shift in heavy industry moving outside of the US, more efficient lights and appliances , and more on-site power, people in the US are using less electricity. As a result, for the first time in a century, electricity demand is stagnant – and utilities are beginning to panic. Via Vox and Earther Images via Deposit Photos ( 1 , 2 )

Comments Off on Volkswagen I.D. Vizzion electric sedan concept takes aim at Tesla’s Model S

With a driving range of 413 miles, Volkswagen’s latest concept sedan aims to beat the Tesla Model S at its own game. Volkswagen has released teaser photos of its new I.D. Vizzion concept, and it features a fully-autonomous system that lets passengers sit back and let the car do the driving. The I.D. Vizzion concept is the latest from the family of I.D. electric cars that VW has released, which started with the I.D. hatchback in late 2016. While the previous I.D. concepts have been previews of VW’s future electric models, the I.D. Vizzion takes it a step further by being the first to feature fully autonomous technology, which VW is going to debut next month at the Geneva Motor Show . Related: Volkswagen may offer more electric cars than any other brand Inside the I.D. Vizzion doesn’t have a steering wheel or pedals. Instead a “digital chauffer” is responsible for piloting the vehicle. The concept car drives, steers and navigates autonomously in traffic, while the passengers are given the freedom to do other tasks. The I.D. Vizzion concept also features a virtual host, which the passengers can interact with via voice or gesture controls. The system also automatically knows the personal preferences of the passengers. The I.D. Vizzion concept is the largest of all the I.D. concepts and previews a premium electric sedan. The concept is powered by two electric motors that generate a combined 302 horsepower that’s sent to all four wheels. A 111 kWh lithium-ion battery gives the concept a driving range up to 413 miles. VW has yet to announce when the production version of the I.D. Vizzion concept will arrive, but the first I.D. model, the hatchback, will go on sale in 2020. The electric hatchback will then be followed by the I.D. Crozz electric SUV and then the microbus-inspired I.D. Buzz . By 2025 VW plans to introduce more than 20 electric vehicles. +Volkswagen All images © Volkswagen

Comments Off on Vacant lots are being transformed into urban bee farms in Detroit

“Work hard, stay bumble,” is the motto of Detroit nonprofit Detroit Hives . The organization aims to conserve honeybees by turning abandoned urban lots into community bee farms. Timothy Paule and Nicole Lindsey started the nonprofit last year, and so far they’ve transformed one lot into a space with vegetable garden plots and three hives – and they’re just getting started. Something’s buzzing in Detroit. Detroit Hives is tackling a few issues, namely honeybee conservation , blight in the city created by vacant lots , and educating the community on bees . Paule told HuffPost the inspiration came from a cold that just wouldn’t go away. A local market worker told him to try local honey for its medicinal properties. He and Lindsey also began to realize how urban blight might play a part in allergies, as overgrown ragweeds took over. They could tackle that issue by producing local honey on vacant sites. Related: America’s first urban ‘agrihood’ feeds 2,000 households for free Lindsey and Paule took beekeeping courses and purchased their first vacant lot for $340 on Detroit’s East Side. Thousands of bees now buzz on the lot, and the neighbors love the farm, according to Lindsey. We transform Detroit Vacant lots into urban bee farms. We are responsible for a quarter of a million honey bees in the East Warren community and we offer tours and bee education for the community. Work Hard, Stay Bumble. #DetroitHives #Savethebees #UrbanBeekeeper #UrbanBeeFarm #Detroit #Michigan #PureMichigan #Nonprofit #VizzeeInc #Honey #Support #Donate #Canon #Beekeeper A post shared by Detroit Hives (@detroithives) on Aug 25, 2017 at 2:47pm PDT She told HuffPost, “They say they wish we were there 10, 20 years ago. That area has always been a place where people dump trash, so when we came there, we gave that area a sense of purpose. The neighbors keep an eye on the area to make sure that people aren’t dumping anymore.” We bring bee consciousness to your community by transforming blighted land into honey bee conservations. #beekeeping #DetroitHives #Michigan #PureMichigan #DNR #MDNR #urbanbeekeeper #blackgirlmagic #beeeducation #rawhoney #adidasoriginals #blackbeekeepers #blackbeekeeper A post shared by Detroit Hives (@detroithives) on Aug 4, 2017 at 10:58am PDT Per Black Enterprise, Detroit Hives has partnered with local vendors like The Black Bottom Brewery, Detroit Soup, and a homeless shelter to provide local, raw honey, and they also sell their sweet product. They offer public tours and speak at schools in the area to help the community learn more about bees. They aim to expand beyond their first farm this year. + Detroit Hives Via Black Enterprise and HuffPost Images via Eric Ward on Unsplash and Massimiliano Latella on Unsplash
