Air pollution might be invisible, but it results in 7 million premature deaths each year. Fortunately, there’s a solution – the CityTree is a high-tech green wall that scrubs the air of harmful particulates – and it has as much air-purifying power as 275 urban trees. As you might have guessed, the CityTree isn’t really a tree . Instead, it’s a moss culture. Zhengliang Wu, co-founder of Green City Solutions said: “Moss cultures have a much larger leaf surface area than any other plant. That means we can capture more pollutants .” The CityTree is under 4 meters tall, approximately 3 meters wide and 2.19 meters deep. Two versions are available – one with or without a bench – and a display is included for information or advertising. Due to the huge surface area of moss installed, each tree can remove dust, nitrogen dioxide and ozone gases from the air. Additionally, the installations are fully autonomous, as solar panels provide electricity and collected rainwater is filtered into a reservoir where it is pumped into the soil. Related: Air pollution is the leading environmental cause of death worldwide The invention also has WiFi sensors which measure the soil humidity, temperature and water quality. “We also have pollution sensors inside the installation, which help monitor the local air quality and tell us how efficient the tree is.” said Wu. Every day, a CityTree can absorb around 250 grams of particulate matter. Over the length of an entire year, the invention can remove 240 metric tons of C02. Green City Solutions seeks to one day install CityTrees in major cities around the world – but they presently faces bureaucratic challenges. Said Wu, “We were installing them (the CityTrees) in Modena, Italy, and everything was planned and arranged, but now the city is hesitant about the places we can install because of security reasons.” Regardless, the company will persist and already has plans to introduce the invention to India , where air pollution has reached dangerous levels in certain locations. So far, 20 CityTrees have been successfully installed in major cities around the world – including Oslo, Paris, Brussels and Hong Kong. Costing about $25,000 each, they are a big investment – but one deemed to be worthwhile as they clean the air of harmful contaminants. + Green City Solutions Via CNN Images via Green City Solutions

Renewables will reign supreme by 2040, latest BNEF report shows

June 21, 2017 by  
Filed under Eco, Green

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 )

Global coal production falls 6.2% in the biggest decline in history

June 15, 2017 by  
Filed under Eco, Green

U.S. President Donald Trump may believe coal is the future , but newly-released statistics by BP Statistical Review of Energy state otherwise. According to the data, global coal production fell by an astonishing 6.2 percent last year — the largest annual decline on record. Additionally, consumption decreased for the second year in a row, dropping 1.7 percent. In wake of these findings, it should come as no surprise that once again, renewables were the fastest growing energy source, growing by a whopping 12 percent — a statistic which represents the largest annual incremental increase in output on record. The report , entitled “Energy markets in transition: BP Statistical Review shows long-term shifts underway,” concluded that the oil market is declining because fast-growing markets are shifting “towards lower carbon fuels as renewable energy continues to grow strongly and coal use falls.” The report also showed that the shift from coal is widespread. The UK, for instance, consumed 52.5 percent less in 2016, the U.S. experienced an 8.8 percent dip in consumption and China’s reliance dropped by 1.6 percent. Evidence to support these conclusions abound. For instance, the UK recently experienced its first coal-free day since the Industrial Revolution. India also intends to halt all coal plant production in the near future, as renewable technologies have become more affordable. Related: U.S. coal production dips to lowest point in 35 years due to rise of renewable energy sources Bob Dudley, BP Group Chief Executive, said, “Global energy markets are in transition. The longer-term trends we can see in this data are changing the patterns of demand and the mix of supply as the world works to meet the challenge of supplying the energy it needs while also reducing carbon emissions . At the same time markets are responding to shorter-run run factors, most notably the oversupply that has weighed on oil prices for the past three years.” As was previously mentioned, renewable energy was the fastest growing of all energy sources, increasing by 12 percent. Though solar, wind and other renewable energy sources provide only 4 percent of the world’s total energy, the increase represents almost one-third of the total growth in energy demand in 2016. Despite certain leaders’ opposition to renewable energy investments, it seems clear the future is green and that consumers will continue to invest in energy sources that are beneficial for the environment, wildlife, and future generations – and their bottom line. + BP Statistical Review of Energy Images via Pixabay

Scientists unveil first printable, stable perovskite solar cell good for 10K hours

June 12, 2017 by  
Filed under Eco, Green

The mineral perovskite has been touted as the next big thing for renewable energy , potentially giving solar cells a 31 percent maximum efficiency – but water-soluble and perovskite solar cells typically don’t last long in the real world. 11 scientists at institutions in Switzerland and Italy may have finally achieved what researchers have been working towards since around 2009: a stable perovskite solar cell. Their solar cells stayed stable in real world conditions for longer than a year. Perovskite solar cells have already been built with an efficiency of more than 22 percent, but that’s in a laboratory. Oxygen and moisture go to work on the cells once they’re outside. But this team led by scientists at Ecole Polytechnique Fédérale de Lausanne drew on a new type of structure in the solar cell to create one the university says is ultra-stable. Related: Austrian scientists create a cheap, flexible solar cell just 3 micrometers thick They designed a hybrid 2D/3D perovskite solar cell. According to ScienceAlert, the 2D perovskite serves as a protective window to guard against moisture, so the 3D perovskite can generate electricity . The solar cells were built up layer by layer – like a sandwich, according to ScienceAlert – by putting different ingredients atop one another. The team built 10 by 10 centimeters squared solar panels , with what the university described as a fully printable industrial-scale process. The hybrid 2D/3D perovskite solar cells are resistant to oxygen and water, while still able to transport electrical charges. They absorb light from the whole visible spectrum, according to the university. The efficiency isn’t great yet – just 11.2 percent. But the university noted that efficiency was constant for over 10,000 hours, with zero loss in performance. Project leader Mohammad Khaja Nazeeruddin told ScienceAlert, “The important finding in this manuscript is identifying the presence of multi-dimensional 2D/3D interface. We believe [this] will trigger many further studies…widening the prospects for perovskite photovoltaics .” The journal Nature Communications published the advance online the beginning of this month.

A swarm of gigantic, glowing sea urchins recently appeared on Singapore’s waterfront for the iLight Marina Bay Festival. Choi+Shine Architects constructed the larger-than-life creatures as “lacy rooms” that invite visitors to walk inside and enjoy their intricate structure and visual effects. The structures are inspired by sea urchin shells, which are elnclosed yet lightweight and porous. The architects recreated the intricate patterns of urchins using white double-braided polyester chord woven in 20 segments and attached to a metal frame. It took 50 people to assemble the structures by hand over a period of two months. Related: Robots helped build and sew together this amazing sea urchin-inspired pavilion Each sea urchin measures 56 feet in size and weighs around 220 pounds. The lacy pavilions are illuminated by white spot lights, creating the illusion that they glow in the dark. The calming effect and simplicity of the installation visually contrasts Singapore’s skyscrapers and celebrates the city’s cultural diversity. + Choi+Shine Architects Photos © 2016, 2017 Choi+Shine Architects

Comments Off on Tesla to power ‘almost all’ Superchargers with solar after disconnecting them from the grid

Tesla wants the world to switch to renewable energy – and the company is leading by example by taking “almost all” of its Superchargers off the grid. The stations have been criticized in the past because they rely on dirty fossil fuels to power up electric vehicles. In response, Tesla founder Elon Musk announced that “almost all” Superchargers will be disconnected from the grid as solar and battery arrays are installed at the company’s 800 stations. Since the Superchargers were unveiled in 2012, Musk has been talking about adding on solar arrays. Now, he’s preparing to launch ‘Version 3’ of the Supercharger while deploying even more battery and solar systems – and he wants to take them off the grid. In response to a negative comment on Twitter, Musk said, “All Superchargers are being converted to solar/battery power. Over time, almost all will disconnect from the electricity grid.” All Superchargers are being converted to solar/battery power. Over time, almost all will disconnect from the electricity grid. — Elon Musk (@elonmusk) June 9, 2017 As Elektrek reports , a recent study concluded that the average electric car in the United States now gets the same efficiency as a (non-existent) 73 mpg gas-powered vehicle . In retrospect, Musk could have made this point and ended the argument. However, he went one step further by unveiling the company’s ambition to take Tesla’s Supercharger network off-grid. Related: Tesla is doubling its Supercharger network by the end of the year to 10,000 chargers The logistics still need to be worked out, as Tesla would need solar arrays as large as football fields at some stations. However, the intention has been set, and if Elon Musk has proven anything, it’s that he’s an innovative leader who consistently takes action. Expect to see improved Supercharger stations that are disconnected from the electric grid in the future. Via Elektrek Images via Tesla , Inside EVs

Comments Off on Zaha Hadid Architects completes first phase of Italys solar-powered high-speed rail hub

Italy is moving full steam ahead on the expansion of high-speed rail. The country recently celebrated inauguration for the first phase of the Napoli Afragola station, a solar-powered high-speed rail hub and major gateway to the south of Italy. Zaha Hadid Architects designed the eye-catching station, which doubles as a pedestrian bridge, and integrated energy-efficient systems such as solar panels and ground source heating and cooling. Located 12 kilometers north of Naples , the Napoli Afragola station will serve four high-speed intercity lines, three inter-regional lines, and a local commuter line. Once complete, the station will connect the 15 million residents of the surrounding southern communities with the national rail network to the north and Europe beyond. An estimated 32,700 passengers are expected to use the station daily once all lines are operational. Zaha Hadid Architects designed the Napoli Afragola station to double as a public bridge connecting communities on either side of the railway. “The design enlarges the public walkway over the eight railway tracks to such a degree that this walkway becomes the station’s main passenger concourse – a bridge housing all the services and facilities for departing, arriving and connecting passengers, with direct access to all platforms below,” write the architects. The elevated station also offers much-needed new public space for the area in addition to shops and other amenities. Related: Wind power now runs all electric passenger trains in the Netherlands Designed as “an extrusion of a trapezoid along a 450-meter curved path,” the sculptural station is constructed with a reinforced concrete base with 200 differently shaped steel ribs clad in Corian and a glazed roof. Natural light pours into the station through the glazed roof to minimize demands on artificial lighting. Integrated solar panels on the roof, natural ventilation, and ground source cooling and heating systems also reduce energy consumption. + Zaha Hadid Architects Images by Jacopo Spilimbergo

Comments Off on Ancient Japanese tombs inspire nendos first public space design

Prolific Japanese studio nendo completed their first public space design that puts a playful and futuristic spin on its unlikely source or inspiration: ancient Japanese tombs. Located at Tenri Station in Japan’s Nara prefecture, the multipurpose public space is a 6,000-square-meter station plaza that includes amenities such as bicycle rentals, cafes, and a play area. The goal of the project, called CoFuFun, aims to encourage revitalization of the area through strengthening community bonds. The whimsical name CoFuFun combines the term ‘cofun’—the name of sacred tomb mounds that the Tenri region is known for—with the colloquial Japanese expression ‘fufun,’ which means happy, unconscious humming. Inspired by cofun’s grass-covered mounds, nendo designed the plaza with a series of circular white structures made from precast white concrete . The modern cofun also reference Nara’s mountainous geography with some structures depressed and others domed. Related: Bangkok’s Siam Discovery retail center gets a major redesign from Japanese firm nendo Steps cover the prefabricated structures, which are used for a variety of uses including seating, shade, play, and even skating. A cafe and other shops are built inside the domed cofuns. “The cofun are beautifuland unmistakeable, but blend into the spaces of everyday life in the city,” says nendo. “The alphabet spelling, “CoFuFun”, also brings in the “co-“ of “cooperation” and “community”, as well as – of course –“fun” itself. The result is a name whose Japanese and alphabet spellings mean similar things, so that foreign visitorsto the plaza will understand it in the same way, too.” + nendo Images by Takumi Ota

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
