Comments Off on New Tesla Powerpack system to offer energy savings of 40-50%

Tesla has pioneered massive battery storage projects this year, such as a 396 Powerpack facility in Southern California. But a recent project in Queensland, Australia reveals installations don’t always need to be huge to make an impact. A system with a single Powerpack and commercial inverter was installed at The Cathedral College in Rockhampton to store solar energy that can help power the boarding school at night. GEM Energy Australia installed a 100 kilowatt solar system on rooftops at The Cathedral College, and some of that energy is stored in the Tesla Powerpack 1.5 during the day. At night, it can power the whole boys boarding house for five hours. The school expects the system will offer them an energy savings of 40 to 50 percent over 12 months, and GEM Energy estimates the school will see a payback in six to seven years. The company said the system cost $285,000 and will offset 40 metric tons of carbon every year. According to Electrek, the system covers 61 percent of the school’s energy , and came online earlier this year.

But this installation of the one-Powerpack system at the Australian school – the first to have such a system installed – reveals the flexibility of energy storage products from Tesla, according to Electrek. The school system also uses a Tesla inverter; when the company put out their latest Powerpack generation, they also released a commercial inverter they developed drawing on their experience with car inverters. The school already seems pleased with the results; Cathedral College ICT Manager Aaron Nunn said in a Tesla video, “I think it definitely does impress upon our students we’re showing good stewardship and respecting the environment and its resources.” Via Electrek and GEM Energy Australia Images via GEM Energy Australia

Comments Off on 7 of the best places to view autumn foliage around the world

It may not feel like it, sweaty and sticky as you may be, but if you are a resident of the Northern Hemisphere, autumn is right around the corner. As fun as it has been to soak up the summer sun, the crisp air, slower pace, and dazzling foliage of autumn sounds like heaven right about now. For those who wish to take advantage of the imminent seasonal beauty, we’ve compiled a list of locations across the Northern Hemisphere that will be bursting with autumnal splendor in the weeks to come. 1. Montreal, QC -> Burlington, VT I’m cheating a bit with this first one, but with less than two-hours in a car separating these two fine cities, it is highly recommended that appreciators of autumn pair both lovely spots. Montreal and Burlington are among the earliest major cities in Eastern North America to reach peak foliage, starting in mid-September and continuing into October. While in Montreal, visitors should hike or bike to the top of Mount Royal, or visit the elevated St. Joseph’s Oratory, for a view of the gorgeous patchwork of color along the St. Lawrence River. Autumn is short but sweet in the city, so enjoy the magic while it lasts. Related: Tiny Fern Forest Treehouse Provides a Cozy Vacation Hideaway in the Woods of Vermont While in Burlington , be sure to bike along the Island Line Rail Trail, from which you can catch breathtaking views of the surrounding mountains, framed by Lake Champlain. Of particular interest is the causeway section, which connects Colchester and South Hero, where visitors can journey out into the lake itself, thanks to a narrow land bridge. 2. Fujigoko Region, Japan Due to its island location and varied elevation, Japan boasts an impressive diversity of climate zones, from subtropical to cold temperate continental. The fall foliage of Fujigoko, also known as the Fuji Five Lakes Region, benefits from its northern location and higher elevation. Underneath the towering Mount Fuji, the five lakes located in an arc to the north of Fuji provide an excellent contrast to the vivid fall foliage. After the sun has set and the cool air becomes cold, visitors should warm up with a bowl of Fujigoko’s famous udon noodles. 3. Prague, Czech Republic Prague seems to be at the top of many people’s list of favorite European locations, and for good reason. The gorgeous architecture, befitting a city founded in the 6th century, is well complemented by the seasonal changes of autumn. As the leaves change color and the sun retreats, Prague shines. The cool air complements the warm, hearty traditional Czech cuisine, which may be enjoyed on a heated patio if the weather cooperates. For breathtaking views of the foliage, take a trip to the top of Petrin Hill or walk through Kampa Island.

Great Smoky Mountains, North Carolina/ Tennessee Although New England receives the lion’s share of praise as the American autumn experience, one would be unwise to ignore the majesty of fall in the South. Great Smoky Mountain National Park, the most visited in the United States, offers unparalleled views of a diverse, rich ecosystem that sheds its leaves in waves, from the top of the Appalachian balds down to the foothills. Related: Jimmy Carter built a new solar plant on his old peanut farm Beyond the park, there are endless spots to explore in the mountains of North Carolina, Tennessee and Georgia . For those based in or traveling from Atlanta, Tallulah Gorge State Park is only a short drive for breathtaking views that may include whitewater rapids, depending on the weekend. 5. Huangshan, China Huangshan, or the Yellow Mountains, is a beautiful mountain range known for its hot springs, sunsets, unique jagged peaks, and top-down views of clouds. Understandably, it is a popular destination all year round, but it truly peaks in the autumn. Maple trees turn vivid red, various deciduous trees become golden, and the Huangshan pine trees provide an evergreen hue. Add in Huangshan’s unparalleled sunrises and your portrait of fall excellence is complete. 6. Highlands, Scotland Though the Scottish Highlands may be known for their plentiful pine trees, the golden aura of deciduous trees play well against this more traditional backdrop. Peak foliage in the Highlands tends to begin in late September and continue into October. Paired with Scotland’s numerous and famous lochs and the rolling mountains, the Scottish autumn is a must-see. After a hike through Cairngorms National Park, relax with a dram and seasonal produce, including wild game, fresh fruit, and oysters. 7. Michigan If you seek a pleasant peninsula, look no further than Michigan. Whether your fall travels takes you to Michigan’s breathtaking, extensive shoreline bounded by four of the Great Lakes or further inland in the Wolverine State, you are guaranteed to be dazzled by Michigan’s natural beauty. In autumn, all things apple are there in Michigan for your enjoyment; after all, the state produces over 900 million pounds of apples each year. If you seek true wilderness, check out Keweenaw National Historical Park for bold fall foliage, historic towns, and shoreline views.

This carbon nanotube yarn generates power when pulled

Comments Off on This carbon nanotube yarn generates power when pulled

Power-producing materials are the stuff of wearable inventors’ dreams. And scientists just created a yarn that generates electricity with a simple tug. The yarn, comprised of carbon nanotubes and submerged in an electrolyte gel, isn’t ideal for sweaters – but can harvest power from a wearer’s breathing. And there’s another surprising application: it could collect energy from ocean waves . An international team of 29 researchers devised the the yarn material, known as twistron harvesters, “by tying a carbon nanotube string into a tangled weave of carbon and submerging it into an electrolyte gel,” according to Science Magazine. When covered in gel and tugged, the yarn can illuminate a light-emitting diode with a small current. The yarn’s peak power generation – when strands are hooked together – is 250 watts per kilogram, and Ars Technica pointed out a professional cyclist’s peak exertions are only around 10 percent of that figure. Related: New type of fabric harvests energy from the sun and movement The researchers tested the yarn by sewing it in to a shirt, and saw it generated a tiny amount of electricity as the wearer breathed in and out. The researchers also connected the yarn to an artificial muscle – a polymer that contracts when warmed, according to Ars Technica – and were able to convert fluctuations in temperature into energy . A still more unexpected way the yarn could be used is in wave power . The material operates when it’s placed in saltwater similar to the ocean, and the motion of the waves moves the yarn, allowing it to generate power. Ars Technica notes the device does need a platinum electrode as seawater can be corrosive. The proof of concept yarn strands aren’t yet powerful enough to brighten a home, but the scientists say their technology is scalable. The journal Science published the research in late August. Scientists from institutions in South Korea, the United States, and China contributed to the study. Via Science Magazine and Ars Technica Images via The University of Texas at Dallas and screenshot

Comments Off on A lacy skin fills this Kenyan apartment building with sunlight and fresh air

This modern apartment building in Mombasa, Kenya is wrapped with a lacy structural skin that allows natural light to filter inside. Urko Sánchez Architects wrapped the building in two layers: the first acts as a barrier against excessive heat and sunlight. The second layer, comprised of handcrafted wood-lattice shutters , further manages light and provides privacy. The building occupies a narrow, sloping lot located on the waterfront of Tudor Creek, Mombasa. This privileged location offers stunning breathtaking panoramic views on the creek. In order to ensure optimal privacy, the architects designed a two-layer shell that provides natural ventilation and prevents heat gain . The facade is inspired by traditional Swahili design and redirects the tendency of local people to put bars on their windows. Related: Lace-like screen inspired by Portuguese tiles cover the rear facade of the charming Restelo House in Lisbon Vegetation is integrated in the patios and on the terraces , offering freshness and greenery. The patios allow natural ventilation via permeable wood lattices facing the water. They are accessible via lateral stairs that descend towards the creek, passing by an integrated gym at the bottom, and arriving to an infinity pool. Related: Ofis’ Colorful Lace Apartment Complex is Wrapped in a Sun-Shading Facade “The skin was rendered entirely structural thanks to the engineering team,” said the architects. “A novelty to Kenya, such structural skin was possible thanks to local and international engineers working hand by hand, and to the steel workers on-site who managed, by dedication and care, flawless bar bending work without access to any technology,” they added. + Urko Sánchez Architects Via World Architecture News Photos by Javier Callejas

Comments Off on Butcher Shop Steals Joke by Vegan Comedian, Goes Viral

When Windsor Meats in Vancouver, Canada posted a funny joke the manager had seen online in their window, the last thing they expected was for the photo to circulate back to the original comedian. The blackboard in the shop’s window read: “Did you know? Vegans live 15 year longer because they aren’t invited anywhere fun or dangerous. Instead they stay at home crying and drinking, being careful not to cry into the drink because tears are a product of animal suffering.” A picture of the board quickly went viral , with meat-eaters everywhere using it as an opportunity to bash vegans and vegetarians for their “lack of humor.” The only problem? The original creator of the joke is a vegan himself.
