Renewable energy is on track to take over the world, if Bloomberg New Energy Finance (BNEF)’s predictions are correct. This month they released their annual New Energy Outlook (NEO) report, which reveals 51 percent of the world’s power generation could come from renewables by 2040. During the next 23 years, 72 percent of the $10.2 trillion spent on new power generation will go into solar power and wind power . The future sure looks bright for renewable energy. NEO 2017 lead author Seb Henbest said their report indicates “the greening of the world’s electricity system is unstoppable” as costs for wind and solar continue to plummet. Batteries will also play a role in the shift of the world from polluting fuels to clean ones. Related: Dropping costs in renewable tech spurs rapid shift to clean energy Coal is on its way out, if the NEO 2017 predictions are correct. The BNEF team wrote in Germany, Spain, Italy, Australia, and the United States, solar is at least as cheap as coal, and in just a few years – by 2021 – it will be less expensive than coal in Mexico, Brazil, the United Kingdom, China, and India. And while the report suggests 51 percent of the world’s power could come from renewables in 2040, Greentech Media pointed out that’s an average. Some countries could get more than 51 percent energy from renewables – countries like Mexico, Italy, Brazil, and Chile could get as much as 80 percent of their energy from clean sources. Wind and solar on their own will account for more than 50 percent of power in Australia, the United Kingdom, Germany, and Mexico. Green technology adoption – like rooftop solar – will be on the rise. Electric vehicles will “bolster electricity use and help balance the grid .” Henbest told Greentech Media, “The cost declines that we are seeing with these technologies are so steep that it becomes a matter of time as to when they start crossing over and becoming competitive in different ways. These things are getting cheaper faster than we thought even a year ago.” Via Bloomberg New Energy Finance ( 1 , 2 ) and Greentech Media Images via Pixabay ( 1 , 2 )

Seattle ‘s famed Space Needle – a 55 year-old icon – is finally getting a much-needed makeover. Helmed by local architect Olson Kundig , the ambitious project will update the structure’s physical systems while renovating the restaurant with a rotating glass floor. In addition, a slanted, all-glass enclosure will be installed around the observation deck to enhance the already stellar views. Space Needle Chairman Jeff Wright, whose family owns the building, hailed the project as a necessity to keep the famed landmark up-to-date: “I believe we’ll look back at this as a pivotal moment in the history of the Space Needle. This project both connects us back to our roots, to the vision that my father and his partners had when they built the Space Needle in 1962, and guides us forward into the future for generations to enjoy.” Related: Olson Kundig Designs Office Made From Wind Turbine Parts In addition to renovated structural elements and more elevators, the proposal calls for adding lots more glass to the beloved structure. The walls surrounding the observation deck, which currently has a cage-like enclosure, will be replaced with massive floor-to-ceiling glass panels to provide uninhibited views of the Puget Sound . A rotating, all-glass floor in the restaurant will give visitors a view of Seattle from above. Although there is no specific time frame for the project, the privately-funded renovation will most likely take years. However, the revamped restaurant and observation deck are slated to be opened by summer of 2018. + Olson Kundig Via Fast Company Images via Olson Kundig and video via Brooklyn Digital Foundry

Comments Off on This gigantic floating Manta Ray could naturally purify Seouls river

What if our city infrastructure could also repair the damage we’ve done to nature? Vincent Callebaut’s Manta Ray is an experimental landscape design that aims to sustainably restore the natural environment in Seoul . Developed for an international competition, Manta Ray is a floating ferry terminal proposal that uses marshland plants to naturally purify the Han River and produces 100% of its energy needs through renewable sources. The Manta Ray is the latest design in Vincent Callebaut Architectures’ extensive portfolio of green utopian designs. His striking proposal for Seoul takes a multilayered approach to the landscape , beginning with the transformation of the existing Yeouido Park on the banks of the Han River into a “genuine cultural hub” reinforced with resilient design principals. A forest of willow trees is proposed for the park, as are marsh-like filtering strips to protect the banks against flooding . Pedestrian paths, large terraces, bicycle lanes, and an amphitheater would be added along the river. The Yeoui-Naru floating three-level ferry terminal juts out of the park and would be suspended above a marina and gardens. On the lower docks is a marina comprising linked steel dikes integrated with equipment to charge boats with water, electricity, and biofuels. Atop the marina is a flared, manta ray-shaped structure that houses the reception, leisure areas, food courts, exhibition space, and educational spaces. Tree-shaped structures made from cross-laminated timber sourced from “eco-responsible Korean forests” crown the building. The top-most level also includes an observation deck with views towards Ban island, as well as a rooftop orchard. Related: How the Cheonggyecheon River Urban Design Restored the Green Heart of Seoul The Manta Ray would produce all of its energy needs from a mix of renewable energy sources. The first includes solar energy harvested from 49,000 square feet of rooftop solar cells installed on the laminated glass facade, as well as 37,300 square feet of opaque photothermal panels. The 52 CLT trees are topped with wind turbines . Organic and biodegradable waste from Yeouido Park would be collected for use at a biomethanation plant to provide energy for Manta Ray, while oscillating-foils hydrokinetic turbines (HAO) would be integrated along the hull of the large floating barrier encircling the marina. “Seoul is finding new ways to invest in this kind of soft infrastructure, helping to foster social cohesion with a greater sense of community among diverse socio-economic groups,” writes Vincent Callebaut Architectures. “With an eye toward increasing equitable access for everyone to these new facilities, this floating vessel is an example of biophilic and resilient architecture, demonstrating that it is possible to build with nature rather than against it, by respecting the life of the river and allowing the local fauna and flora to flourish. The “Manta Ray” project promotes the permeability and renaturalization of river banks in cities with rivers running through them. The banks become new playgrounds for social innovation, and for urban “consumers-actors” seeking to promote urban farming, agroforestry and permaculture. The goal is to make them less vulnerable to climate change, and to the subsequent dramatic flood and urban heat island events witnessed over the past decades.” + Vincent Callebaut

Bio-inspired wind turbines with flexible blades 35% more efficient

Comments Off on Bio-inspired wind turbines with flexible blades 35% more efficient

Wind energy already yields four percent of Earth’s power, but five researchers at French institutions recently drew inspiration from nature to make wind turbines even better. Inspired by creatures like dragonflies, they found flexible blades on wind turbines make the machines much more efficient. Wind turbines today work best under optimal wind speeds, but the new bio-inspired design could offer a way around that fact, making wind power even more accessible. Wind speeds impact the functioning of a wind turbine. If the wind is too slow, the turbine won’t turn and generate energy; if the wind is too fast it could damage the turbine. Wind also must hit the turbines at the correct pitch angle to apply the correct amount of torque to the generator, according to Science. The new research from scientists at Sorbonne University and École Nationale Supérieure des Arts et Métiers-ParisTech fixes these issues with flexible blades much like insect wings. Related: Revolutionary flapping wind turbine mimics hummingbirds to produce clean energy The researchers constructed prototypes with regular hard turbine blades, slightly flexible turbine blades, and very flexible turbine blades. The last design turned out to be too floppy, but the slightly flexible blades outperformed the rigid ones, offering as much as 35 percent more power . They also continued to work in lower wind conditions and weren’t as susceptible to damage in high winds. The journal Proceedings of the Royal Society A published the research online in February. But the scientists’ work isn’t yet done: they now need to search for the right material that’s “flexible, but not too flexible,” according to lead author Vincent Cognet, to scale up the findings. Engineer Asfaw Beyene of San Diego State University, who was not part of this study, told Science, “The fluid mechanics and the physics make absolute sense. There’s no reason why we cannot make morphing blades that will adapt to wind conditions.” Via Science and Tech Xplore Images via Joi Ito on Flickr and Pexels

Comments Off on Dilapidated 1800s dairy barn resurrected into a stunning home in Wyoming

Architecture firm JLF Design Build has breathed new life into a dilapidated 1800s dairy barn by transforming it into a stunning new home. “The Creamery” was built using materials salvaged from an abandoned dairy farm in Montana and reconstructed just outside of Jackson Hole, Wyoming. According to the architects, the ambitious project focused on retaining the same “authentic craftsmanship and rugged austerity” of the original stone building, while converting it into a contemporary living space. According to the creamery’s history, the original structure was built by anonymous Scottish stonemasons who laid two-foot-thick walls that lasted centuries. However, left empty and and unprotected for decades, the structure fell into severe disrepair. After convincing their antique-loving clients to acquire the original barn as “the ultimate antique”, the team used painstaking care to gather and transport as much of the old building’s materials as possible to Wyoming where they rebuilt a stunning new home in an idyllic setting. Related: 6 barns converted into beautiful new homes The home’s stone structure pays a beautiful homage to its original design, both on the outside as well as the inside. The interior decoration is pure rustic sophistication, with beautiful stone walls, exposed wooden trusses on the ceiling and large reclaimed wood planks as flooring. The structure is now home to a family who appreciates the timeless architecture of the design, “The relic itself inspired a sense of responsibility to its origins,” says JLF Design Build principal Paul Bertelli. “This building in its existing form, with its scale and proportion, was much purer than any contemporary architectural solution we could have applied. Ultimately doing nothing at all was the genius of the architecture in this project.” + JLF Design Build Photography by Audrey Hall

Scientists discover plants have ‘brains’ that decide when to sprout

Comments Off on Scientists discover plants have ‘brains’ that decide when to sprout

Researchers are quickly learning that plants are far more complex than once thought. Not only has it been determined that plants are capable of sensing and preparing for drought conditions, a team from the University of Birmingham recently learned that a cluster of cells in seeds act like a brain that decide when they should germinate. As a result of this finding, crop yields may be improved. The study, published in the journal  Proceedings of the National Academy of Sciences (PNAS) , explains that the researchers worked with a species called thale cress to determine whether or not plants have human-like “brains.” After locating the group of cells in the seed that are responsible for controlling decision-making processes, they discovered something interesting. Reportedly, the group of cells is made up of two competing types: one promotes germination and the other promotes dormancy. The scientists describe the relationship as a “tug of war” match, as hormones are swapped back and forth in a process that’s very similar to mechanisms in the human brain when someone decides whether or not to move. The team says the separate competing cells are key to the decision-making process in both humans and plants . The mechanism serves an important purpose in vegetation, because germinating too early may result in death due to frost. Alternatively, germinating too late will result in growing complications due to the wrong climate conditions. Said George Bassel, lead author of the study, “Our work reveals a crucial separation between the components within a plant decision-making center. In the human brain , this separation is thought to introduce a time delay, smoothing out noisy signals from the environment and increasing the accuracy with which we make decisions. The separation of these parts in the seed ‘brain’ also appears to be central to how it functions.” Related: Seed-Planting Tumbleweed Robot Draws From Nature to Fight Desertification After creating a mathematical model of how the separate cells work to control how sensitive the plant is to its environment , the researchers concluded that the more variation there is in environmental conditions, the more seeds will sprout. This sounds counter-intuitive, but the results were confirmed when the team tested it in a laboratory. “Our work has important implications for understanding how crops and weeds grow,” said Bassel. “There is now potential to apply this knowledge to commercial plants in order to enhance and synchronize germination, increasing crop yields and decreasing herbicide use.” + Proceedings of the National Academy of Sciences (PNAS) Via New Atlas Images via Pixabay

The wind turbine manufacturer putting unemployed coal miners to work

Comments Off on The wind turbine manufacturer putting unemployed coal miners to work

The transition to clean energy isn’t always easy for workers in fossil fuel industries. As coal miners find themselves out of work, one wind turbine manufacturer aims to give them jobs in clean industries through a free jobs training program. Goldwind Americas , the United States branch of a major Chinese company, wants to offer out-of-work coal miners in Wyoming new roles as wind technicians instead. The Bureau of Labor Statistics says wind turbine service technicians is the fastest growing occupation in America, with a median pay of $52,260 a year in 2016, and some of those jobs could be a perfect fit for skilled laborers who no longer have employment in the fossil fuel industry. Goldwind’s Wyoming job training initiative, Goldwind Works, could produce workers for a huge wind farm they’re building in the state, where they have an agreement to supply up to 850 turbines. After construction they’ll require up to 200 workers to maintain the wind farm. Related: Clean energy jobs outnumber fossil fuel jobs in most US states Goldwind Works is slated to start next month. It will include informational meetings and a tower climb and safety training at a Montana wind farm. Goldwind Americas CEO David Halligan told The New York Times coal miners likely already possess some relevant mechanical and electrical skills, and are used to laboring in hard conditions. He said, “If we can tap into that market and also help out folks that might be experiencing some challenges in the work force today, I think that it can be a win-win situation.” Wyoming produces more coal than any other state in America. They produce almost four times as much of the black rock as West Virginia. Even so hundreds of coal miners lost their jobs in the state last year. Meanwhile the wind industry could offer new opportunities to those out-of-work miners. Via Greentech Media and The New York Times Images via Pixabay and Goldwind Global

Comments Off on World’s most powerful wind turbine breaks 24-hour record for energy generation

Anyone who still thinks wind power is just a load of hot air obviously hasn’t been paying attention. Witness the V164 , a prototype wind turbine that Denmark’s MHI Vestas Offshore tested at Østerild over December. With a rated power of 9 megawatts under optimum conditions, the V164 set a new energy-generation record by a single wind turbine by producing a staggering 216,000 kilowatt-hours over a 24-hour period. The V164 is no glorified windmill. Standing nearly 722 feet tall, the V164 boasts with a sweep area of 227,377 square feet—or larger than the London Eye. Its 262-foot-long blades, the equivalent of nine London double-decker buses, weigh 77,160 pounds apiece. The platform is part of MH Vestas Offshore’s “continued commitment to deliver affordable offshore wind power,” Torben Hvid Larsen, the firm’s chief technical officer, said in a statement. Related: The World’s Most Powerful Wind Turbine Has Blades That Are Over 24 Stories Tall “We are committed to delivering turbine technology that is in line with the development of our industry, based on our 20-plus years of offshore experience,” he said. “Reliability remains a key enabler, and our approach to developing our existing platform supports this strategy.” With the new record secured, the prototype is now ready to go to market. Built with the unforgiving North Sea environment in mind, V164 has an operational life span of about 25 years, after which 80 percent of it can be recycled. “We believe that our wind turbine will play an integral part in enabling the offshore industry to continue to drive down the cost of energy,” Larsen added. + MHI Vestas Offshore Via New Atlas
