FacebookTwitterLinkedInEmailPrint分享The Independent:A floating tidal stream turbine off the coast of Orkney has produced more green energy in a year than Scotland’s entire wave and tidal sector produced in the 12 years before it came online. In 12 months of full-time operation, the SR2000 turbine supplied the equivalent annual power demand of about 830 households.Its developer claimed the machine– the most powerful of its kind in the world – had set a benchmark for its industry due to its performance. It produced 3GWh of renewable electricity during its first year of testing at the European Marine Energy Centre.Over the 12 years before its launch in 2016, wave and tidal energies across Scotland had collectively produced 2.983GWh, according to Ofgem.Andrew Scott, chief executive officer of developers Scotrenewables Tidal Power, said: “The SR2000’s phenomenal performance has set a new benchmark for the tidal industry. “Its first year of testing has delivered a performance level approaching that of widely deployed mature renewable technologies.”He added: “The ability to easily access the SR2000 for routine maintenance has been a significant factor in our ability to generate electricity at such levels over the past 12 months, including over winter.”The team at Scotrenewables said their success – combined with Meygen’s generation of more than 8 GWh over the past year from four tidal turbines deployed in the Pentland Firth – is evidence that tidal power generation could be rolled out more widely.More: Scotland’s floating turbine smashes tidal renewable energy records Tidal energy facility smashes generation records in first year of operation

Two new large solar plus storage projects planned in South Australia FacebookTwitterLinkedInEmailPrint分享Renew Economy:Two new massive solar and battery storage projects have been proposed for South Australia, continuing the momentum in new investment that will likely see the state produce the equivalent of 100 per cent of its electricity needs through wind and solar as early as 2025.One of the new projects – a $1.2 billion proposal for 500MW of solar PV to be accompanied by 250MW/1000MWh of battery storage – has broken cover in the state’s planning approval process. The application was filed by consultants Energy Projects Solar Pty Ltd, and is proposed for a site just east of Robertstown, about 115 kms north east of Adelaide.The same company is also proposing a 280MW solar farm and battery storage facility near Port Pirie, known as the Bungama solar project.It says the Robertstown Solar project – subject to financing – is likely to be built over four stages, and the battery storage facility will also be built in stages. Synchronous condensers may also be installed if required by the grid and market operator.South Australia has already reached more than 50 per cent share of wind and solar in its grid, mostly through large scale wind (44 per cent) and rooftop solar (7-8 per cent). That share is growing as more projects come on line. Gupta himself proposes some 1GW of solar and storage in the state to help power Whyalla and other big energy users, and AEMO has predicted enough wind and solar could be built by 2026/27 to generate more than is consumed in the state.More: Huge solar and battery storage projects proposed for South Australia
FacebookTwitterLinkedInEmailPrint分享Greentech Media:NV Energy one-upped its huge 2018 solar and storage procurement on Tuesday, announcing three new solar projects totaling 1,200 megawatts paired with 590 megawatts of battery storage.Colin Smith, a senior solar analyst at Wood Mackenzie Power & Renewables, called the procurement “hulkingly big.” When built, one of the projects — at 690 megawatts — will be the largest solar plant in the U.S., according to tracking from WoodMacThe three solar-plus-storage projects, developed by 8minute Solar Energy, EDF Renewables and Quinbrook Infrastructure Partners and Arevia Power, should be complete by 2023. Two will be built on the Moapa Band of Paiutes Indian River Reservation, in partnership with the tribe.Aside from their massive size, the contracts also come as a vote of confidence in utility-scale solar-plus-storage, according to analysts. Developer 8minute said its project could run 65 percent of the time during peak summer hours, as opposed to the 29.9 percent availability of the average solar plant in Nevada. “That’s really a paradigm shift from the utility had to take my power whenever the sun was shining to the utility telling us what their customer’s needs are and we design and engineer a power plant to fit those criteria,” said Tom Buttgenbach, president and CEO at 8minute. “The days of renewable equals intermittent and a headache for utilities to integrate into their systems is now reversed to where this delivers exactly what the utility wants.”WoodMac’s Smith said the back-to-back, big-time procurements show that utilities can make the quick transition towards renewable resources that’s under discussion in states and at the federal level through policies like the Green New Deal. “When we go back to the question of, can we make the transition fast enough to help climate change, it’s easy to point to someone like NV Energy, which is a pretty large utility in a pretty large state,” said Smith. “They’re moving towards renewables at a pretty rapid pace.”More: NV Energy announces ‘hulkingly big’ solar-plus-storage procurement Nevada utility announces another round of massive solar-plus-storage projects

Back in December we profiled Fairview, North Carolina ultra runner Peter Ripmaster and documented his astonishing goal to run 1,000 miles through the heart of Alaska in the middle of winter.Now Ripmaster is deep into his 1,000-mile trek of the historic Iditarod dog sled route which runs from Knik to Nome, Alaska.Unlike the dog mushers of Iditarod fame, Ripmaster is attempting complete his journey on foot while hauling 30 to 40 pounds of requisite survival gear in a sled behind him.According to reports coming out of Alaska today, Ripmaster endured what could have been a life-ending ordeal on Friday, March 4, when an ice bridge he was using to cross Alaska’s notoriously torrential Tatitna River collapsed, sending him directly into the frigid rapids below.Adventure blogger and journalist with the Alaska Dispatch News Craig Medred, who published one of the first reports about Ripmaster’s incident, said the North Carolina runner was able to pull himself from the dangerously cold and swift waters of the Tatitna before logging some of his fastest miles yet en route to the shelter of a nearby cabin.“His eyes were wide,” an Invitational checkpoint volunteer who was manning the cabin at the time told Medred. “We got to him and started stripping him down. He was pretty shaken up there for a while.”At last account Ripmaster was said to be back on the trail, continuing his quest for completion of the epic 1,000 mile journey.According to Medred, there as a failed attempt to reach Ripmaster by phone on Saturday which missed him by only five minutes as he passed through the Athabascan Native village of Nikolai deep in the Alaskan interior.For more info on Ripmaster read our feature story in the December issue of Blue Ridge Outdoors Magazine.[divider]Related Articles[/divider]
In today’s world, the spectrum of how-to #vanlife is huge: you could go cheap, throw a mattress on a couple of milk crates, and call it a day, or drop a few grand and deck your rig out in all of the modern day comforts of home. Our van buildout fell somewhere in the middle, and at under $1,000, we managed to upgrade the milk crates to a savvy system of space-saving storage, wire-free lighting, and eco-friendly power without breaking the bank.Check out Adam’s step-by-step buildout below!Strip the van completely. Tear out old insulation in the floor and remove all “utility van” accessories. Start with a clean slate!!!Address any problem areas.Insulate all cavities in the body of the van with fiberglass and foam insulation. (There are a lot of ways to do this, but this is how I did it).Wrap the entire inside of the vehicle with Tyvec. Tyvec is a moisture barrier, and will eliminate rust issues as a result of condensation.Insulate the floor and wheel wells. I used two layers of carpet backing material to provide cushion and R-Value.Add flooring material. Finish the floor by installing trim pieces by both the side and back doors.Now, with a starting point, lay out your floor plan.Build the bed platform. Leave a rough opening for a drawer and cut two holes in the back for storage you can access from the back doors. The underside of the bed is where a majority of our belongings are stored.Install the ceiling. I used ¼” plywood. It’s flexible, strong, light, and easy to install.Finish remaining insulation. I cut ½” foam insulation to fit each window cavity and then used spray adhesive to stick carpet backing material all over the walls to be used as sound deadener and added R-Value.Now, with the bed platform in place and all the insulation complete, your van build out will take a very custom spin. Your layout decisions will cater to the functionality and purpose of the space you are creating. For Jess and I, storage and functioning workspace is what we needed most. I build a tall closet that is wide enough and deep enough to access easily and capable of storing a good deal of miscellaneous stuff.Our cabinets, which there are only two of, serve as our food pantry, our kitchen, and our bathroom. In a separate location above the desk space there’s a small cubby that acts as our office supply space. Throughout this process, remember to be patient. Nothing in a van is square, level, or plumb. It’ll take some time to finagle and construct. Of course, no one can be sure that what you are building now will work for you later, but you have to start somewhere.With the bed, closet, and cabinets in place, we found there was still a need for extra storage and seating. By installing a small bench seat with a flip-up lid, opposite the wall with the cabinets, we were able to achieve both. A small slide-out table (designed around the width and height of our Crazy Creek Leisure chairs) provides us the luxury to dine in front of one another, while still cherishing the small amount of floor space we have when the table is retracted. To cover the insulation on the walls, I again, used ¼” plywood to custom fit panels that gave the van a more finished look. Collectively we painted and caulked. Jess began to give the van the essential “homey touches” before the paint could even dry.The final, perhaps most daunting, task was still ahead. To finish the walls, I needed to rummage some upholstery skills. Slowly, but surely, I spline rolled fabric behind the panels of plywood and used adhesive spray to ensure that overtime the fabric stayed. Dark gray fabric contrasted the white panels nicely. Finally, the ten-day project I had spent at least four months obsessing over, was finally finished!BRO-TV: How to Make a Van Home in 10 Days from Blue Ridge Outdoors on Vimeo.Finishing the van was like turning a page in a book that leads you to a new chapter. There are still a lot of pages to go to complete the book, but it feels good to begin a new chapter. It’s exciting to think about the places our home on wheels will take us, the places we’ll get to go, and the folks we’ll get to meet. The van will serve as an epicenter for creativity, a spark of inspiration that will come and go with each new day on the road.A big thanks to our boss, coworkers, friends, and family that helped us get rubber to pavement! A special shoutout to Pap for use of his shop, expertise, and humor, to the Daddio’s for the contribution of these awesome lights, and to Momma Ritter for her exceptional patience and sewing skills.Like what we’re wearing?

June 23, 2018: Day1/7 The dense foliage on the riverbank loosened up a bit giving us windows to view the wide escarpment. This “valley” sits high and spreads for miles with huge grey granite domes and walls visible to the north and east and west. It felt like we were paddling on top of the world descending in a broad rift, truly the Yosemite of the East! For several miles the river bank opened up giving wide choice of downward paths and an ever increasing view of the surrounding valley. The tannin water spiraled deep into smooth holes in the rock, sometimes three or four clustered together. Austin, Luke and I jumped in laughing and tumbling over one another until we finally got spit out sending us down a slippery 75 foot rock slide. We paddled and portaged deeper into the gorge under a gloomy sky. It was like moving down a thick broken plate, smooth and fissured folding the four of us into a funnel. The sun was lowering over a large granite dome to the west as we paddled downstream. All this became a green blur at the first bend as the rhododendron grew taller and constricted and the sun broke out. Suddenly the creek disappeared over the horizon and we pulled over to scout Upper Warden Falls, a 45-50 foot rock slide. John and I portaged river left while the boys eyed the drop. We joked that the physics of creek boating becomes more challenging at our age. Luke and Austin slid over portions of the falls “testing it out” and landed in the deep pool below. There were several of these large slides and we became bolder with each one lying down like riverboarders. The day started full of sunshine and strutting. Sitting in the soft green moss at the confluence of Panthertown and Greenland creeks we dangled our feet in the freezing water and arranged our gear under a tight canopy of rhododendron. I used my Iphone to take a short video of the “origin of the Tuck” and reviewed the plan. I would lead on my inflatable standup paddleboard, my sons Luke and Austin would follow in their kayaks and John would go last on paddleboard acting as the “safety boater”. I stood up on the board and floated into an eddy. I watched my grown boys on the riverbank test kayaks and equipment; spray skirts, foot pedals, helmet straps and paddles. I taught them well on rivers like the French Broad, Ocoee, Chatooga, Big Laurel, Tallulah and Nolichucky. Standing up on a paddleboard and moving fast down a shallow rocky creek is intoxicating but unforgiving. If the the fin catches on a rock the board stops abruptly and the paddler is launched forward on outstretched hands, much like a snowboarder “catching an edge”. The dark canopy and tea-colored water made avoiding rocks a real challenge but John and I did well and enjoyed the sense of flying downstream. Passing through exotic highland bogs at an elevation of 3,700 feet the rocky banks were softened by lacy Appalachian shoestring ferns, spongy green mosses, white reindeer lichen, pink shell azaleas and mountain doghobble. The 6 miles to the Rock Bridge (end of the American Whitewater “East Fork of the Tuckasegee” section) took us 6 hours. It was getting late so we quickly portaged up and down the steep private lands to the left past the unrunnable waterfall. It was 2 more miles down to the Tanasee reservoir. I had little idea how far that really was! In the comments section on the East Fork ( American Whitewater), John Pilson says, “FYI, there are a few big drops down from Rock Bridge before the Tanasee Reservoir that I’ve hiked but it was before I thought about kayaking much. That land is private land. Wonder if anyone has run em?” The boys were exhausted after hours of climbing in and out of kayaks, dragging the 40 pound boats over boulders, lowering them down slots and crevices. It was certainly easier for John and I to hop off our paddleboards and carry these light inflatables by the handle. Luke’s eyes were sunken and wild ever since “lunch”. While John enjoyed a nice sandwich, chips and a cookie my boys were given rations; one tuna packet and one energy bar and some water. Austin put on a sheepish grin after this and just nodded and smiled when I apologized for not packing a bigger lunch. These are large boys; 6ft. 3 inches a piece! Resting on the sandy beach of Tanasee Creek Lake we gazed up into the dark slot. Luke pulled out his drone and flew it straight up the falls documenting the gnarly drama. Unrunnable, barely hikable and grateful not to be spending a cold and hungry night in the gorge we celebrated with whoops and dancing and paddled the mirror-like reservoir to our camp. We pushed on leaving the relative comfort of Panthertown to uncharted waters with little chance of rescue. Pushing deeper into the gorge it engulfed us. The black granite walls rose high and narrowed and the light was diffuse and hazy. Green moss hung down from the banks and slimy green algae glistened on the smooth rocks. I crossed the slick rock face, my left hand grasped the safety line holding me on the high pitched granite wall, my right hand holding the paddleboard which dangled down over the water. My eyes were blurry and there was a wet breeze funneling up from far below. I tried not to look down, grateful my sons had already gone around. Below was a high volume boulder pointed up like an anvil with logs jammed on either side. This was a disappearing sieve from which even a body recovery would be impossible. The east fork of the Tuckasegee river disappeared into a thundering blackness. The boys were perched precariously high on a ledge with their boats. It was dark and very slippery. John and I locked eyes and had a silent conversation, “we’re screwed; can’t go upstream, can’t go downstream and it is getting late. No more fun time; let’s solve this”. Austin and Luke stayed with the boats, John climbed up the west bank and I went up the east bank. It was very steep, high appalachian climbing, vertical, root by root. I stopped and looked up, discouraged by the steepness and the unlikely chance of a passage around this enormous drop. The next ledge was a deer path, narrow and perched along the jutting gorge rim. Exhausted I followed it all the way up and over and down the quarter mile to the Tanasee Reservoir. I ran back to the group and found John shaking his head, no luck on the west bank. We have a trail, I said, grab your boats and watch your step. Stay tuned for daily logs of the rest of their trip! Rock Bridge Rapid
The Australian Koala Foundation has confirmed that the koala is functionally extinct. With only 80,000 koalas left in the wild, the foundation has determined that there aren’t enough left to support a new generation. The term “functionally extinct” means that the koala no longer has any effect on its environment and that any genetic disease or pathogen that may come along would effectively end the species all together. Climate change and deforestation are being blamed for the koala’s decline. Heat waves have caused thousands of koalas to die of dehydration and deforestation has wiped out the koala in 41 of the 128 Federal environments where they are known to live.
By Dialogo December 17, 2009 Arturo Beltran Leyva, a Mexican drug kingpin nicknamed the “boss of bosses,” was killed in a dramatic shoot-out with the navy south of Mexico City, the government said Thursday. Beltran Leyva was Mexico’s third most wanted man, with a 1.5-million-dollar (one-million-euro) reward on offer for information leading to his capture. The leader of a breakaway faction of the notorious Sinaloa drug cartel was killed late Wednesday, along with six cartel members, after a months-long manhunt, said the office of President Felipe Calderon. “An intense battle between presumed members of Beltran Leyva’s criminal cartel organization and members of the Mexican Marine infantry in the city of Cuernavaca resulted in the death of seven members of the Sinaloa cartel,” a statement read. Beltran Leyva, 47, led a feared drug-trafficking operation of international reach and shared blame in drug violence that has left more than 14,000 dead in Mexico in the past three years. One soldier died during Wednesday’s operation at a block of flats in Cuernavaca, a popular weekend retreat outside the capital with a population of 350,000. The firefight was so intense that many residents had to be evacuated to a nearby sports stadium, local radio reported. The operation had been planned for months after extensive intelligence work, admiral Jose Luis Vergara, a Navy spokesman, told a local television station. The Beltran Leyva cartel was formed after a split with the powerful Sinaloa cartel headed by fugitive drug kingpin Joaquin “El Chapo” Guzman. Guzman escaped from a Mexican prison in 2001 and appears in Forbes magazine’s world billionaires list. Arturo Beltran Leyva reportedly worked with the Colombia Norte Del Valle cartel to distribute cocaine and other drugs in the United States. In August 2008, the US Justice Department unsealed indictments against him and 42 other defendants in connection with drug trafficking. The indictments claimed they had imported and distributed nearly 200 metric tons of cocaine and large amounts of heroin in the United States and smuggled cash proceeds of up to 5.8 billion dollars through the United States and Canada. He was also accused of hiring hitmen “who carried out hundreds of acts of violence in Mexico, including murders, kidnappings, tortures and violent collections of drug debts.” Calderon’s office described Beltran Leyva as an ally of the “Zetas” — former paramilitaries working with the Gulf cartel. One of Arturo Beltran Leyva’s brothers, Alfredo, was arrested in January 2008 in the first major drug capture for the Calderon administration. The conservative Mexican president has staked his office on tackling the drug cartels with a controversial crackdown involving some 50,000 security forces across the country. Drug gang influence extends throughout Mexican society, infiltrating even the police and politicians. Bloody violence between drug gangs, particularly struggles over lucrative smuggling routes into the United States, has left the region along Mexico’s border with the United States one of the most dangerous in the world.
On 24 March, following the arrest of nine suspected liaisons for the powerful Mexican Sinaloa cartel, President Rafael Correa affirmed that drug-trafficking organizations are operating in Ecuador. “It’s beyond doubt that drug cartels are functioning in the country (…) What is not the case is that we’re in a situation like the one in Mexico, because (there) they dominate entire territories,” Correa said in a radio interview. On 23 March, the Ecuadorean police announced the arrest of four Ecuadoreans, three Mexicans, and two Colombians in an operation with the Mexican police, who detained another nine people allegedly linked to the Sinaloa cartel, led by the mob boss Joaquín ‘Chapo’ Guzmán. The gang is believed to be linked to around four tons of cocaine seized in Ecuador in recent months, according to the police. “I have to get more information about the operation, but in principle, it corroborates it,” Correa indicated with regard to the Sinaloa cartel’s presence in the country. He added that “it seems that this information is correct; the police are acting, and they’ve had a significant success with this operation.” “Ecuador still continues to be an island of peace in the whole of Latin America,” although “we can’t ignore the reality, however much it pains us at heart, that (…) our two neighbors (Colombia and Peru) are the two largest producers of drugs in Latin America and the largest in the world,” he declared. “Expecting Ecuador to be untouched by this problem of drugs and organized crime is demagoguery,” Correa said, emphasizing that “we’re combatting them here and being successful.” In addition, he declared that his administration has ordered the Armed Forces to act jointly with the police, because “there’s no country in the world that has succeeded in defeating organized crime without collaboration.” The police have not ruled out the involvement of the Sinaloa cartel in the death of an anti-drug agent on the outskirts of Quito on 19 March.
