“British scientists first noticed a dramatic thinning of ozone in the stratosphere some 10 kilometres above Antarctica in the mid 1980s. Ozone is important because it blocks out harmful ultraviolet radiation from the Sun. Its absence increases the chances of skin cancer, cataract damage, and harm to animals and plants.”
Now, researchers have found “that in September 2015 the hole was around 4 million sq km smaller than it was in the year 2000 - an area roughly the size of India. The gains have been credited to the long term phasing out of ozone-destroying chemicals.”
Watly, a 15-ton, 130-foot-long computer, uses energy from 80 solar modules to purify water, provide wireless coverage, and power or charge other devices. Its inventors say it can meet these daily needs for about 3,000 people.
Attisani says he’s working to bring Watly’s price down as he refines a new model, due in July. He’s also working on a water purification unit that’s one-tenth Watly’s size, which he plans to price at €20,000 or less. Rachida Justo, an entrepreneurship professor at IE Business School in Madrid, says Watly’s potential justifies the upfront cost. “I see a lot of innovation in just one machine,” she says.
Roughly a billion cicadas will soon take over parts of Ohio, West Virginia, Virginia, Pennsylvania, Maryland and New York, filling the air with their raucous mating call.
The invasion only lasts six weeks. Once the baby cicadas, also called nymphs, have hatched from their eggs in the trees, they’ll fall to the ground and burrow into the soil, not emerging for another 17 years. Underground they survive off moisture from tree roots. Cicadas don’t eat solid food.
The adult cicadas are a gluten-free, low-fat, low-carb source of protein. They’re a favorite treat of dogs and cats.
The Rising Creek Bakery in Mount Morris, Pennsylvania, is making special cookies and custard to mark the 17-year occasion. Bakers freeze cicadas, remove their wings and coat them in sugar before placing them on top of a chocolate chip cookie or custard with caramel sauce, CBS Pittsburgh reported.
Pair the paint with related tech like infrared-reflecting windows, and the effects are amplified. When the DOE tested a Cadillac STS with infrared-reflective glass (offered by automakers including Mercedes, Volkswagen, and Volvo) and solar reflective paint, it found the car’s cooling demands dropped by 30 percent (from 5.7 to 4.0 kW).
Though city dwellers may not realize it, agriculture is a big source of carbon emissions. That’s because of livestock’s production of methane, how manure is handled, and soil management (something as simple as tilling the soil releases greenhouse gases). Dairy geniuses Mike and Sue McCloskey, partners in one of the country’s biggest dairy operations, have come up with an elegant approach to tackling several of these problems at once in the hopes of creating a zero-carbon footprint dairy farm. At the heart of the operation: a process that turns their dairies’ tons of cow manure into natural-gas fuel. Here’s how it works.
Subcultron is a swarm of at least 120 self-directing, underwater robots being developed by scientists in six countries to monitor Venice’s polluted waterways and transmit environmental data to government officials.
The 21-year-old Dutch is the founder and CEO of The Ocean Cleanup, an ambitious operation involving a massive static platform that passively corrals plastics with wind and ocean currents. The array features a floating V-shaped boom so that fish and other marine life can swim underneath.
Further trials will take place off the coasts of Japan and the Netherlands, and if all goes to plan, the project will officially launch in 2020 and be the longest floating structure ever deployed in the ocean.
Engineers with the BMI Corporation and SmartTruck Systems ran models on Jaguar and Titan, two of the fastest supercomputers in the world available for open science projects.Truck models were put through computational fluid dynamics simulations, which were verified to accurately predict airflow within a tenth of an inch on a real vehicle. They also applied a genetic algorithm that mimicked the process of natural selection to optimize their design.
The work resulted in a trailer undercarriage tray that reduced drag and brought fuel savings of 6 percent. With additional refinements and components behind the trailer tandems and on the trailer’s sides, the 300-pound SmartTruck system can achieve 10 percent fuel savings.
Dutch airline KLM and Delft University of Technology have released concept designs for an aircraft with a "blended wing body", which could transport passengers non stop from Europe to Australia.
The AHEAD aircraft, which stands for Advanced Hybrid Engine Aircraft Development, would carry 300 passengers over a range of 14,000 kilometres – approximately the distance from Amsterdam to Perth.
To improve aircraft efficiency and allow for longer flights, KLM's engineering and maintenance department worked with engineers and designers at Delft University of Technology (TU Delft). The result is a design that features two sets of wings – a small pair by the nose and a large set at the rear – that blend into the body.
China has been installing more renewable-power capacity than fossil fuels for several years, a gap that's growing. In 2015, China will install 15 gigawatts to 18 gw of solar power alone, double the solar deployment in the U.S., according to an analysis by Bloomberg New Energy Finance (BNEF).
The chart below shows how, in the next 15 years, China is on track to have more low-carbon electricity than the entire capacity of the U.S. power grid. "Think of what their grid will look like in 2030," Michael Liebreich, founder of BNEF, said at the organization's annual summit last week in New York. "A very competitive advantage."
