Google Street View cars are helping scientists spot methane leaks

March 23, 2017 by

The Google fleet has been mapping cities around the world for years, making navigation easier for travelers. Now they have an important new responsibility: Google Street View cars will seek out natural gas leaks in urban areas. The data will not only help cities protect citizens from potentially harmful gas leaks, but also help cut accidental greenhouse gas emissions. The project was outlined in a new paper published in the journal Environmental Science and Technology . It’s a collaborative effort between Colorado State University researchers, the Environmental Defense Fund , and Google that involves attaching methane sensors to Google Street View cars. Related: Google Street View takes you inside the fiery depths of an active volcano The cars have been outfitted with special infrared lasers that can detect the amount of methane in the surrounding air in real time. Experiments found that the sensors had a range of about 65 feet, more than enough to detect leaks in urban settings where pipelines run beneath or near public streets. So far, the cars have found that there may be many more methane leaks in America’s major cities than previously believed. Cities with more modern pipelines were far less likely to have leaks, while Boston —the worst offender—was found to have thousands of leaks, resulting in a loss of about 1,300 tons of gas per year.

Methane is far more potent than carbon dioxide, and leaks could seriously accelerate climate change if they aren’t addressed. Via The Washington Post Images via Wikipedia

Filed under Eco, Green

Solar panels just got a lot slimmer. Zhengrong Shi, a.k.a. the Sun King, is now marketing eArche, a super flexible, ultrathin solar panel that could stretch along building facades, atop buses, or on top of carports to charge electric cars. According to Shi, the groundbreaking panel has unlimited potential, and 40 kilowatts (kW) of the new technology has already been installed in three locations throughout Australia . eArche draws on a composite material like that utilized in airplane windows that is almost 80 percent lighter than conventional photovoltaic panels, according to RenewEconomy. Shi is distributing his new products through Australian company Energus and Hong Kong company SunMan , and believes eArche is the biggest innovation in over 10 years in the solar industry . He told RenewEconomy, “Most of the cost reductions we have seen come from manufacturing, growing efficiency, and supply chain. There has been very little innovation on products and applications, so we have decided to focus on the panel itself, which has been very rigid and heavy.” Related: SolarWindow unveils new energy-generating glass that bends Some companies haven’t been able to install solar because panels are too heavy for their buildings’ roofs, but Shi’s technology could remove that issue. Rooftop solar systems typically weigh around eight metric tons for a 100 kW array, according to The Daily Advertiser, but eArche weighs just around two metric tons for 100 kW. Shi said eArche can be custom-shaped for building roofs or walls. He told RenewEconomy, “We think governments should require all new buildings to have solar panels integrated into their structure. With this panel, it is easy to do.” SunMan also envisions the technology on RVs, yachts, vending machines, and more. Time will tell if eArche is as revolutionary as Shi thinks. The technology stands in contrast to Tesla’s proposed solar tiles , which Shi said is “the wrong way of doing it” largely due to expense and weight.

This ultra-green house for a Seattle family of four has achieved an exceptional level of sustainability without compromising on aesthetics. Shed Architecture & Design designed the Madrona Passive House as a net-zero residence for former Microsoft program manager and renowned environmental advocate Jabe Blumenthal. With a super-insulated envelope and passive design features such as heat recovery systems, photovoltaics, green roofs and stormwater and rainwater harvesting, the house minimizes its energy consumption and act as a stellar example of climate-friendly living. The 3,700-square-foot home relies on solar panels , high-performance construction and a contemporary design for its energy efficiency. A well insulated envelope which includes a Zehnder ComfoAir heat recovery ventilator that pumps fresh air into the interior contributes to its low energy consumption . This technology also recovers 90 percent of thermal energy from exhaust air for reuse inside. Rainwater from the home’s roof and the green roof on the garage goes into two cisterns via permeable pavers, while mechanical shading system and triple-pane windows regulate solar gain . The owners can also tap into the building’s real-time consumption by using the circuit-by-circuit energy monitoring system with dashboard.

Swedish researchers develop low-cost wood filter to purify water in refugee camps

March 22, 2017 by  
Filed under Eco, Green

At least 780 million people in the world lack access to clean water , a dire problem exacerbated by the increasing number of people living in poorly-equipped refugee camps . Researchers from KTH Royal Institute of Technology in Sweden may have come up with a low-cost, low-tech solution: a portable wood filter that doesn’t require a power source to produce clean water. KTH scientists developed a material from wood cellulose that can trap bacteria , and are testing the material for use as a water filter. PhD student Anna Ottenhall said, “Our aim is that we can provide the filter for a portable system that doesn’t need electricity – just gravity – to run raw water through it…The bacteria-trapping material does not leach any toxic chemicals into the water, as many other on-site purification methods do.” Related: Researchers design cheap mercury-free LED foil to purify water https://www.youtube.com/watch?v=1NaJ2zRPleQ The wood cellulose fibers utilized are antibacterial, and are dipped in a positively-charged polymer solution to create the material, which works since bacteria and viruses are negatively charged, according to Phys.org. The harmful viruses and bacteria stick to the material, unable to get free or reproduce, and eventually die. Another benefit of this method of purification is that bacteria won’t be able to build up a resistance to it. The Swedish research team envisions their material used as a water filter in places that lack wells or infrastructure, like refugee camps or in emergencies. After use, the material can simply be burned. Bandages, packaging, and plasters could potentially draw on the material as well to dispose of bacteria in ways that don’t put toxins into the environment . KTH researchers are developing several other wood-based materials along with this wood water filter, such as see-through wood, a wood polystyrene alternative, and squishy wood batteries.

Trump plans to strip NASAs earth science division, promote mission to Mars

March 22, 2017 by  
Filed under Business, Eco, Green

On Tuesday, President Donald Trump signed into law a new plan for NASA’s future . The NASA Transition Authorization Act of 2017 calls for a $19.5 billion annual budget for the agency – not a major change from the agency’s $19.3 billion budget in 2016 – but the document seems to leave out the agency’s earth science division entirely. Trump claims this is simply a way of reaffirming the agency’s “core mission” of human space exploration, space science, and technology, but given how aggressively the new administration has gone after any agencies involved in atmospheric research, climate change denial is likely the underlying motive for the shift. Under the new act, Congressional Republicans have outlined a new roadmap for the agency’s future. The law calls on NASA to create a plan for humans to reach the surface of Mars by the 2030s, and to continue developing its Orion space capsule and its Space Launch System. The administration has also expressed a desire for NASA to return to the moon in the 2020s. Related: NASA releases startling new images showing 30 years of change on Earth What’s unclear is exactly how the new law will affect NASA’s earth science research. Trump’s proposed budget , however, may offer some clues. He hopes to cut the earth science budget by $102 million, potentially terminating a number of programs, including the   Plankton, Aerosol, Cloud, ocean Ecosystem  (PACE),  Orbital Carbon Observatory-3  (OCO-3),  Deep Space Climate Observatory  (DISCOVR), and  CLARREO Pathfinder missions. These four satellites help scientists monitor the Earth’s climate, weather, and oceans. While Trump may claim climate change is outside of the scope of NASA’s original research mission, that’s simply untrue. When NASA was formed in 1958, the National Aeronautics and Space Act explicitly called on the new agency to contribute to the “expansion of human knowledge of phenomena in the atmosphere.” The loss of these resources would be devastating to the larger scientific world, which often relies on NASA data for research. Related: Gov. Jerry Brown pledges to launch California’s “own damn satellite” if Trump blocks climate research It’s still far too early to know what might happen: the funding requested would be for the 2018 fiscal year, so any cuts wouldn’t be felt immediately. The proposed budget also has to be reviewed and approved by Congress before anything is set in stone. Hopefully, lawmakers will see the value in maintaining some of these programs, even if Trump doesn’t. Via Business Insider Images via   NASA

Comments Off on India could have its own Hyperloop system within 38 months

Past and present modes of transportation simply do not compare to the impressive abilities of  Hyperloop  technology. This efficient, low-cost vision of the future could be making its way to India in the next few years, according to Hyperloop Transportation Technologies (HTT) co-founder Bibop Gresta. He argues a system of high speed tubes that transport people and cargo could help ease the challenges associated with extreme population density and a dearth of infrastructure. Hyperloop technology involves a series of tubes with an interior vacuum-like environment, through which pods can zip from point A to point B at nearly the speed of sound. Forbes India interviewed HTT co-founder Gresta about his vision for the country – one he thinks could become reality in as little as three years. Related: BIG releases video sneak peek of Hyperloop designed to connect Abu Dhabi & Dubai “The Hyperloop is based on efficiency,” Gresta said. “The cost of creating it can sometimes be one-fourth the cost of a high speed rail, and the cost of operations can be one-fifth.” He also argues that construction and operation costs, as well as projected passenger rates of $20-$60, are based on American pricing and that these costs in India would be smaller. He has already met with Prime Minister Narendra Modi and the chief ministers of several states which his Hyperloop proposal would affect, and said the response was a positive one. Gresta said the country could have a functional Hyperloop system in place within just 38 months, once the project is approved. “We are ready with the technology and we can bring the money,” he explained. “We just need land and a commitment from the government of India.” A similar Hyperloop project is already underway in the capital of the UAE, where feasibility studies are being done to run the system between Abu Dhabi and the city of Al Ain. + Hyperloop Transportation Technologies Via Forbes India Images via Wikimedia , Getty Images

Comments Off on The Venus Project envisions a sustainable redesign of our cities and civilization

While countries worldwide advanced significantly, we still grapple with issues like poverty, crime, or homelessness. 100-year-old futurist Jacque Fresco and architectural illustrator Roxanne Meadows founded The Venus Project to not only address these problems, but also to redesign cities to make them more sustainable. These circular cities draw on technology and science to produce a better society with a less harmful environmental impact. The Venus Project thinks our monetary system is dehumanizing and leads to dysfunctional behavior. According to Meadows, who spoke in an interview with Futurism, the founders advocate what they call a Resource Based Economy, which calls for resources to be distributed equitably without money or credit. Services and goods would be available for all people for free, much like checking out books at a library. Related: The galaxy-shaped Indian utopia built on principles of no money or government Although The Venus Project offers a vision for redesigned cities , architecture isn’t the project’s sole focus. Meadows told Inhabitat, “The Venus Project is more than just architecture ; it is about a new social design. The architecture is built with that in mind and designed to conserve resources and maintain a high standard of living so the entire global population can have access to adequate housing , nutritious food, clean water, and all the amenities an advanced technical civilization can achieve. The Venus Project’s architecture is not isolated from its social direction; no branch of science should be.” A main idea of The Venus Project is to move past politics . Meadows said politicians are rarely experts on preventing climate change or developing clean energy sources, for example. Instead, they often work to maintain the status quo and serve the interests of the wealthy and powerful. Meadows told Futurism: “It is not ethical people in government that we need but equal access to the necessities of life and those working toward the elimination of scarcity. We would use scientific scales of performance for measurement and allocation of resources so that human biases are left out of the equation. Within The Venus Project’s safe, energy-efficient cities, there would be interdisciplinary teams of knowledgeable people in different fields accompanied by cybernated systems that use sensors to monitor all aspects of society in order to provide real-time information supporting decision-making for the well-being of all people and the protection of the environment .” The team completed a 21-acre research center in Florida as the first phase of the project, and are working to get the ideas out to the public through documentaries and a film in the second phase. They also aim to construct an experimental research city. + The Venus Project Via Futurism Images courtesy of The Venus Project

How Sweden plans to heat homes with internet searches

Comments Off on How Sweden plans to heat homes with internet searches

Emails and Instagram photos don’t come without a carbon footprint : they’re stored in data centers which continually battle excess heat and suck up electricity to cool servers. But Stockholm, Sweden recently came up with a rather ingenious use for all that waste heat : what if it could warm homes instead? Most data centers aren’t very environmentally friendly. According to one estimate, they consume roughly the same amount of power as the airline industry, and the amount of electricity used in the centers could triple during the upcoming decade. But data center heat could help cities transition away from fossil fuels in a major way. Just one 10-megawatt data center can provide enough heat for 20,000 apartments. Related: Why Microsoft is dropping data centers on the ocean floor Stockholm started an initiative, Stockholm Data Parks , for their vision of “a data center industry where no heat is wasted.” Under the initiative, renewable energy will power data centers, and heat produced will be sold to district heating company Fortum Värme , which has been looking to biomass or waste heat to provide heating instead of fossil fuels. The presence of a district heating system sets Stockholm up to utilize data center heat on a large scale. Stockholm’s district heating system has already begun working with small data centers, and Stockholm Data Parks said on their website they will bring together, prepare, and offer “all necessary infrastructure elements at attractive greenfield and brownfield sites suited for data center activity.” Power grid operator Ellevio and dark fiber provider Stokab are participating in the initiative along with Fortum Värme. Some data centers do operate on renewable energy, but if their excess heat could go to a district heating system, Stockholm’s data centers could even become carbon positive. A 10-megawatt center could lower emissions by 8,000 metric tons. Since Stockholm’s goal is to go fossil fuel free by 2040, the Stockholm Data Parks vision could push the country closer to that target. + Stockholm Data Parks Via Fast Company’s Co.Exist Images via Pexels and Stockholm Data Parks
