Water freezes at zero degrees Celsius or 32 degrees Fahrenheit, right? While that’s water’s freezing point, under certain conditions liquid water can be supercooled – and still be liquid . Two groups of scientists recently uncovered new details about supercooled water, showing there could still be a lot we don’t know about this fairly common substance. Water just got weirder. We know supercooled water drops can exist naturally in the planet’s atmosphere , at temperatures as low as negative 35 degrees Celsius, according to Gizmodo . It isn’t easy for scientists to measure the temperature of supercooled water droplets, but a team led by Goethe University Frankfurt pioneered a new technique – for drops as small as a micrometer – that shows liquid water can exist at negative 42.55 degrees Celsius. Their research was published in Physical Review Letters earlier this month, with scientists at institutions in Germany, Italy, France, and Spain contributing. Related: Scientists discover water has not one, but two liquid phases Meanwhile, Stockholm University published other groundbreaking research on supercooled water last month in Science – and here’s where things get really weird. The scientists found that at normal pressure and a temperature of negative 44 degrees Celsius, water “can exist as two distinct liquids with different ways to bind the water molecules. The water can not decide what shape to be in without fluctuating between these two,” per the university’s press release . They explained it’s similar to how we may be unable to make up our minds on a decision and go back and forth over different options. They discovered many of water’s weird properties “reach a maximum at negative 44 degrees Celsius.” Supercooled water may be a cool topic, but why should you care? Physics said in their synopsis of the Goethe University Frankfurt research, “Knowing when water freezes and when it stays liquid at these low temperatures could improve understanding of atmospheric ice formation and help researchers develop more reliable climate models.” Via Stockholm University , Physics , and Gizmodo Images via chuttersnap on Unsplash and Stockholm University

Comments Off on Macron offers 18 scientists the chance to "Make Our Planet Great Again"

France’s president Emmanuel Macron had an answer to President Donald Trump’s decision to tug America out of the Paris Agreement : invite scientists to research climate change solutions in his country instead. The Make Our Planet Great Again initiative now has its first class: 18 scientists from around the world. They’ll move from institutions like Princeton University, Stanford University, and the National Oceanic and Atmospheric Administration to work in France. Macron announced the 18 grants with French research minister Frédérique Vidal right before the One Planet Summit , a meeting convened by Macron, World Bank president Jim Yong Kim, and United Nations Secretary-General Antonio Guterres to work towards climate action . 12 of the 18 scientists were based at American research centers, laboratories, or universities. Others come from institutions in Canada, Spain, India, the United Kingdom, Poland, and Italy.

Comments Off on World’s first ocean pollution-eating Seabin launches in the UK

UK waterways are about to get a lot cleaner with the launch of the world’s first production Seabin in Portsmouth harbor. The device, which was developed by a pair of Australian surfers, works by sucking in various kinds of pollution (including oil) and spitting out clean water. The Seabin can collect approximately 1.5 kg of waste each day and has a capacity of 12 kg — and in a given year, a single bin can collect 20,000 plastic bottles or 83,000 plastic bags. The Seabin was first unveiled in December 2015. To fund the invention , founders Andrew Turton and Pete Ceglinski created an IndieGoGo campaign. With little time to spare, the campaign exceeded its goal. Equipped with $250,000, Turton and Ceglinski are now prepared to follow through with their plan, which entails cleaning up marinas with the natural fiber garbage bin and an automated, above-the-water pump. The device was designed with marine safety in mind – only debris and chemical pollution on the surface of the water is collected; fish and other aquatic creatures are left alone. The Times reports that the Seabin was installed near the base of the Land Rover Ben Ainslie Racing (BAR) team in the Portsmouth harbor. The group is passionate about environmental efforts – not only have members pledged to give up meat every Monday, they only consume sustainable seafood. Now, they’ve agreed to oversee the Seabin, which will improve the quality of water while protecting the cage of over 1,000 oysters near the pontoon. Related: New study reveals plastic pollution in the Antarctic is 5x worse than expected The Seabin team are also conducting trials at Spain’s Port Adriano and the Port of Helsinki (Finland). In early November, the innovative device will go on sale for £3,000 ($3,957). + Seabin Project Via The Times , Engadget Images via Seabin

Comments Off on Boston man crosses harbor in a pumpkin boat

Tis the season… to get nuts with pumpkins . Christian Isley of Boston , Massachusetts took infatuation with that adorable, orange squash to a new level; he made a boat out of his homegrown pumpkin and sailed across Boston Harbor. “If there’s something odd to be done, he’ll do it,” said Steve, the squash sailor’s father. “Once he puts his mind to something it gets done, no matter how crazy it is.” Appropriately on the morning of the first day of October, Isley the Younger took a ride in his 520-pound vegetable boat, carved by himself and reinforced by wooden planks, foam, screws, and rope. Boston Harbor itself is a story of success for its historic restoration after decades of neglect and pollution . By the 1970s, the Boston Harbor and the feeding Charles River were toxic. After the Metropolitan District Commission (MDC) was compelled by the courts to clean up the region’s water in the 1980s, the rich coastal ecosystem recovered rapidly. Today, the Harbor is swimmable and the Charles is teeming with life. Related: How to cook a whole pumpkin (seeds, guts and all) Native to North America , pumpkins are an excellent source of Vitamin A. The “classic pumpkin” variety is the Connecticut Field; Isley’s boat was made out of an Atlantic Giant. Grown in Belgium , the largest pumpkin ever weighed 2,624.6 lbs, setting the record in 2016. Prior to setting his prize-winning gourd vessel onto the open waters, Isley informed the United States Coast Guard of his plans. Although they expressed their wish that Isley not take the plunge, they did not stop him. Although the cucurbit ship did face some choppy seas , it navigated quite smoothly. “It’s a [expletive] journey,” Isley shouted as he finished the first leg of his adventure. Isley, thanks to his years of experience with boats, completed the quest, as friends and family cheered him on from nearby vessels. “That’s victory right there,” said Isley. “Absolutely. [Expletive] yeah.” Via the Boston Globe Images via the Boston Globe

Comments Off on Monumental inverted pyramid home in Spain will blow your mind

Just when you thought you’ve seen it all when it comes to home architecture, along comes one of the most imaginative homes yet. This inverted pyramid cutting into a hill in rural Spain is a mind-bending villa that offers epic views of the surrounding forest and the swimming pool below, in a shape that you wouldn’t expect.  The residence was designed as a thought-provoking way to reinvent how homes interact with their environment. Tokyo-based Makoto Takei + Chie Nabeshima /TNA designed the home to contrast the landscape, and to surprise and delight. Part of the Solo Houses project, which included design proposals from twelve architects, the pyramid volume houses a variety of spaces defined by several mezzanines and platforms that provide visual connections throughout the interior. A stairway leads to an outdoor swimming pool that was conceived as a huge volume embedded into the terrain. Related: Juan Carlos Ramos Unveils Amazing Pyramid House Worthy of a Pharaoh Large windows draw natural light into the interior and provide views of the forest. Three bedrooms occupy the top floor. These private quarters are connected to the main living areas via a lounge. Different heights and sloping exterior walls make the space feel more spacious and airy. This layout also allows the light from the windows to reach the furthers corners of the interior. + Makoto Takei + Chie Nabeshima TNA Via Fubiz

Comments Off on Evovelo unveils cute little solar car you can pedal like a bicycle

Today Evovelo unveiled a tiny solar-powered vehicle that combines the advantages of a car — such as safety, weather protection and stability — with the ease of a bicycle and the low energy consumption and space utilization of a light electric vehicle. The cute little trike is called Mö, and its practicality, customization, and sustainability make it a great fit for commuters looking to lower their environmental impact. Mö is perfect for short commutes, as it is made from sustainable materials and it has an all-electric range of up to 50 kilometers (31 miles). The vehicle has a top speed of 45 Km/h (about 30 mph), and a set of roof-mounted solar panels rapidly recharge the vehicle’s 1000Wh battery. A single hour in the sun will yield 5-10 kilometers of range, and the vehicle will fully recharge in 3-4 hours. The tricycle can also be propelled by pedal power to further extend its range, and a regenerative braking system stores energy as the vehicle slows down. Its dimensions of 140 cm wide, 200 cm long and 130 cm high means Mö doesn’t take up much space; however, it is large enough to seat two adults up front and two children in the back with optional kids seats. Because Mö has a full lighting system, turn blinkers, safety belts, a front crash crumple zone, side impact protection, and other safety features, one can feel comfortable commuting in the environmentally-friendly vehicle. The vehicle’s battery can be removed and charged at home, in the office, or in a garage – wherever one has access to an electrical outlet. Evovelo’s new prototype officially debuted today in Malaga, Spain, and more information — including its cost — will be released in the near future. + Evovelo

Comments Off on Renewables will reign supreme by 2040, latest BNEF report shows

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 )

Comments Off on New biofuel from wastewater slashes vehicle CO2 emissions by 80%

An innovative new project called LIFE+ Methamorphosis is pioneering a new sustainable biofuel for cars . Car company SEAT and water management company Aqualia have transformed wastewater into the alternative fuel . Powered with this biofuel produced during one year at a treatment plant in Spain, a vehicle could circumnavigate the globe 100 times. SEAT and Aqualia came up with a creative answer to the issues of pollution from traditional car fuels – which have led to traffic restrictions in cities like Madrid – and reusing water , a scarce resource. To make their biomethane , wastewater is separated from sludge in treatment plants, and then becomes gas after a fermentation treatment. Following a purification and enrichment process, the biogas can be utilized as fuel. Compared against petrol, production and consumption of the biofuel releases 80 percent less carbon dioxide, according to SEAT . The new biofuel works in compressed natural gas (CNG)-fueled cars. Related: Africa’s newest sustainable biofuel grows on trees The project aims to show feasibility at industrial scales through two waste treatment systems. The UMBRELLA prototype will be set up in a municipal waste treatment plant serving Barcelona. The METHARGO prototype will create biomethane at a plant handling animal manure. The biogas made with the second prototype can be utilized directly in cars or could be added to the natural gas distribution network, according to the project’s website . A mid-sized treatment plant can handle around 353,000 cubic feet of wastewater every day, which could yield 35,000 cubic feet of biomethane, according to companies involved with the project. All that biomethane could power 150 vehicles driving around 62 miles a day. SEAT will supply vehicles to test the biofuel over around 74,500 miles. The European Commission is funding the project. Other companies participating include Fomento de Construcciones y Contratas , Gas Natural , the Catalan Institute for Energy , and the Barcelona Metropolitan Area .

Comments Off on Rammed earth school in Vietnam blooms like a colorful jungle flower

The far reaches of northern Vietnam are beautiful but heartbreakingly poor. Children of the Hmong ethnic minority who live in the villages routinely suffer from lack of access to healthcare and education. Vietnamese architecture firm 1+1> 2 has provided a ray of hope for those in Lung Luong village in the remote Thai Nguyen Province with the construction of a beautiful new school made from local materials including rammed earth and bamboo. The school’s beautiful swooping and colorful form is an inspiration to the village and serves as a welcoming haven protected from the harsh elements. The Lung Luong elementary school is sited on a mountain peak and constructed to replace a poorly insulated structure that was piercingly cold in days of heavy rain and draught. Under the leadership of architect Hoang Thuc Hao, the villagers excavated part of the peak to create an even foundation. The excavated soil was recycled into rammed earth bricks used to build the school’s structure. The soil bricks’ thermal properties help maintain a temperate indoor climate year round. Locally sourced timber and bamboo were also used in construction and existing trees were protected during the building process. The elementary school is spread out across the mountaintop, covering an area of over 1,400 square meters. The orientation and placement of the buildings and the swooping colorful bamboo canopy above optimize natural lighting, ventilation, and sound insulation. The school comprises classrooms, playgrounds, gardens, multipurpose rooms, a medical room, library, kitchen, toilets, and dormitory. Related: Rammed earth house blends traditional materials with modern techniques in Vietnam’s last frontier “The goal of this project is to create a school with conveniences striving against the harsh nature,” write the architects. “The classrooms are compatible with the mountain, spaces between them are slots which makes everything appears like an architectural picture pasted on the terrain. The corridor connects all functional areas. The foundation of the buildings respects the natural terrain which means that they wind up and down as the mountain path.” + 1+1> 2 Via ArchDaily Images © Son Vu

Diapers, sanitary products could provide alternative fuel source

Comments Off on Diapers, sanitary products could provide alternative fuel source

A waste-management company has developed a new, patented process that turns sanitary products, baby diapers, incontinence pads, and other so-called “absorbent hygiene products” into power. PHS Group , which serves 90,000 households, schools, offices, and retirement homes across the United Kingdom and Ireland, says that it handles about 45,000 tons of the stuff a year. A plant in the Midlands is currently converting 15 percent of that waste into compressed bales that can be burned to provide fuel for power stations. Refuse-derived fuel is neither an untested concept in Europe, where the practice is par for the course, nor in the U.K., where it’s gaining ground. But diapers, tampons, and their ilk have proved trickier because their dampness makes incineration most costly. But neither is dumping them in the landfill, where they’ll take decades to degrade, a sustainable solution. “Hygiene products are an essential part of many of our everyday lives but disposing of them has always been an issue,” Justin Tydeman, CEO of the PHS Group, told Guardian . PHS Group’s system, which is being evaluated by the University of Birmingham for its effectiveness, not to mention its impact on the environment, sounds simple in principle. Related: How Sweden diverts 99 percent of its waste from the landfill The company begins by shredding and squeezing the material, then disposing of any waste liquid as sewage. The remaining dry material is packed into bales, ripe for tossing into the fire. “Whether or not it turns out to be a major source of energy in itself, the key thing is we find a good way to handle what is a complex and growing waste stream,” Tydeman said. “We don’t want this stuff just going into the ground.” An aging population makes PHS Group’s tack even more vital than ever, Tydeman added. “The great thing about life today is people are living longer, but what comes with that is often incontinence issues,” he said. We want this to be a growing issue, because we want people to live longer.” Via the Guardian Photos by Unsplash , Pixabay
