2 May 2014Endless strikes, and bargaining tactics characterised by violence and intimidation, are damaging both to workers’ own interests and to the economy, President Jacob Zuma told a Workers’ Day rally at the Peter Mokaba Stadium in Polokwane on Thursday.Zuma used the Workers’ Day celebrations to call on union leaders and mine owners to find common ground to end the crippling three-month strike over wages affecting the platinum belt in South Africa’s North West province.“Unions must always be alive to the realities that endless strikes are not in the interests of the economy, and indeed are not in the interests of workers themselves,” Zuma said at a Congress of South African Trade Unions (Cosatu) rally.While democracy had given unions and workers several rights – including the rights to fair labour practice, forming and joining a union, and collective bargaining – these rights had not come cheaply, and should be used by workers “constructively to better their lives and determine their destiny,” Zuma said.The right to strike should never be allowed “to degenerate into anarchy … The methods of engagement employed by trade unions must always appreciate that we now have a democratic government put in place by an overwhelming majority of our people, most of whom are workers.”At the same time, Zuma called on companies not to exploit their labour, but to “respect the rights of workers and pay them proper wages in line with the labour framework”.He added that the mining sector needed to move faster in achieving the objectives set out in the Mining Charter. “I think we should all agree that the time has come for the situations on the mines to change.”Source: SAnews.gov
These are two of a growing number of advances in marine energy, which has lagged far behind solar and wind power because of the difficulties of operating in harsh ocean environments and the technical challenges of harnessing tidal and wave power. “The technology has kept moving forward, which is good news,” says Ted Brekken, an associate professor of energy systems at Oregon State University. “But the big issue is to get the cost down. Right now, there is the reality of surviving while we get there.” Editor’s note: This blog was originally posted at Yale Environment 360.In the Pentland Firth, a strait that separates the Orkney Islands from Northern Scotland, strong tidal currents have challenged sailors for centuries. But some of that marine energy is now being captured through a project known as MeyGen. This summer, the Atlantis group began construction on a submerged tidal turbine array consisting of four three-bladed seabed-mounted turbines, enough to deliver 6 megawatts to the grid by 2016 and power approximately 3,000 Scottish homes.By the early 2020s, Atlantis is planning to build 269 turbines in the firth, capable of generating 398 megawatts of electricity, enough to power roughly 200,000 homes.On the other side of the world, off the coast of wave-rich Hawaii, Oregon-based Northwest Energy Innovations installed a wave energy conversion device in June that extracts power from the vertical and horizontal motions of waves using high-pressure hydraulics. Located at a test facility built for the U.S. Navy, the 45-ton apparatus, named Azura, bobs in waters off Kaneohe Bay on Oahu. A small, experimental device with a capacity of only 50 kilowatts, Azura is the U.S.’s first and only grid-connected wave energy system. Momentum seems to be gainingExperts say the real future of tidal energy lies with arrays of floating or sea-bottom-mounted turbines that capture the energy of tidal currents in unobstructed waters — so-called in-stream technology. The most logical place to develop tidal energy is in Nova Scotia’s Bay of Fundy, where the world’s most extreme tides — rising and falling more than 50 feet — contain more than 50,000 megawatts of theoretical power. About 2500 megawatts can easily be extracted with no discernible environmental impact from one inlet — the Minas Passage — alone, according to Stephen Dempsey, executive director of the Offshore Energy Research Association (OERA), a non-profit group.In 2014, the Fundy Ocean Research Center for Energy (FORCE), another research hub, installed underwater power cables in the upper portion of the Bay of Fundy that can transmit a total of 64 megawatts, equivalent to the power needs of 20,000 homes at peak tidal flows. A handful of companies are preparing to hook up their turbines to the grid.“The scale and challenge these devices represent; their physical construction; thousands and thousands of pounds of steel — it takes that type of financial commitment for the industry to get started, and I am seeing it,” Dempsey says. “This is serious business. It is real.”Although it lags behind tidal, the wave energy sector also has been gaining some momentum. In Hawaiian waters, at 100-feet depths, Azura’s device sits partially submerged in the waves, with yellow-steel arms reaching upward. Azura has already begun construction of a second full-scale device that also will be tested in Hawaii. In Australia, Carnegie Wave Energy has developed its so-called CETO wave technology, which consists of fully submerged buoys that drive pumps linked to electricity-generating pods. After 16 years of development, Carnegie last year successfully tested a grid-connected array consisting of three 240-kilowatt buoys, supplying Australia’s largest naval base with power and desalinated water.Multinational companies with the wherewithal to take the marine industry to the next level are making significant acquisitions. In 2013, the French energy giant DCNS acquired Open Hydro, which now has nearly one gigawatt of marine energy projects under development worldwide, including two tidal turbines in the Bay of Fundy and two off the coast of Brittany in France. A vast, untapped resource that works around the clockOcean waves and tidal movements hold vast amounts of energy. The U.S. National Renewable Energy Laboratory estimates that more than one third of all electricity used in the United States could be drawn from the seas. Still, worldwide, ocean power is forecast to produce only 1 gigawatt of electricity by 2020, a mere fraction of the 370 gigawatts generated by wind at the end of 2014.The $400 million in investments in the marine energy sector were dwarfed last year by the $150 billion in investments in solar power. And important questions remain about the environmental impacts of marine energy technologies.Despite its halting start, the marine energy industry has increasingly strong advocates around the world. Currently, about 30 tidal and 45 wave energy companies are at an advanced stage of technological development. One recent report said that ocean energy could satisfy 10% to 15% of European Union power demand by 2050, enough to serve some 115 million homes.The promise of marine energy is tied not just to the enormous potential power that lies in shifting tides and the movement of waves, but also its dependability. In most forms it can generate electricity around the clock, eliminating the need for energy-storage systems and making it easier to integrate into the grid than variable solar and wind power. “At some point, all the easy, cheap installations for wind and solar will be done,” says Brekken. “And then it’s ocean energy that’s next in line.”Another advantage of marine energy devices is that they can be tailored to specific sites and costs. They can serve remote shoreline communities that otherwise depend on expensive diesel or overland transmission lines. That’s already true for the Kvichak watershed in Alaska, where Maine-based Ocean Renewable Power Company deployed a small-scale tidal system in July to reduce the community’s high energy costs. Questions about the impact on marine lifeOne thing holding up deployment of marine energy, especially in the U.S., is uncertainty over how tidal- and wave-energy devices may affect marine ecosystems. How do marine animals interact with tidal turbines, which feature rotating blades that could kill them? How does the sound of devices interfere with the ability of marine mammals to navigate, migrate, and communicate?Strangford Lough in Northern Island, where Atlantis operates a tidal turbine, is home to harbor seals, grey seals, and harbor porpoises. Although the turbine at Strangford shuts off when a marine mammal approaches, environmental scientists are nevertheless studying turbine impacts.A project known as MeyGen off the northern coast of Scotland will include an array of four undersea turbines capable of producing a combined 6 megawatts of electricity when the project is complete next year.“We have to prove beforehand that there is no impact, and we cannot [do that],” explains Dr. Andrea Copping of the Pacific Northwest National Laboratory’s Marine Sciences Laboratory. “We have no concrete proof, just theories based on existing knowledge and computer modeling.” But Copping thinks that regulators are becoming more understanding that some outcomes simply can’t be known, and says, “We are seeing incremental progress in regulatory processes that will support getting devices in the water.” Regional hubs are key to developmentA key step in the research and development of tidal- and wave-power devices has been the creation of joint public-private “hubs” where researchers from companies, universities, and government can test marine energy devices. In Oregon, the Northwest National Marine Renewable Energy Center — run by the U.S. Department of Energy and institutions like Oregon State University — has been operating an off-grid testing site since 2012. It is currently seeking permission to develop a utility-scale, open-ocean facility with a connection to the utility grid.Europe now has at least thirteen such hubs, although not all of them currently are testing devices. MeyGen tested its tidal energy device at the European Marine Energy Center (EMEC) in the Orkney Islands, which has 14 berths for experimenting with early phases of both tidal and wave technologies.In the wave sector, Finland-based Wello Oy has been testing its 500-kilowatt Penquin wave energy converter at EMEC since 2011, but it will soon fill a larger berth at WaveHub — a full-scale wave test site off the coast of Cornwall in the U.K. — for a newer version of its Penguin technology.The tidal industry sector, which has existed much longer than the wave energy sector, holds the most promise. Traditional tidal technologies relied on artificial barriers across shoreline estuaries that hold and release tidal flows. The water, when released, drives turbines. But these barriers take a toll on the environment; France’s La Rance barrage, opened in 1966, has caused progressive silting of the area’s ecosystem and has contributed to the disappearance of species such as sand eels and plaice.But when barriers are already in place as flood control systems, modern tidal devices can be effectively installed with little additional environmental impact. Last month, Tocardo Tidal Turbines installed five linked tidal turbines under the Eastern Scheldt storm surge barrier within the Dutch Delta Works.

High-Speed Cinematography TutorialWhen slowing down playback at 24 fps your video editing app will fill the gaps with frames, creating a slow motion effect. There are further ways to enhance this effect in post using After Effects.The video covers:Shooting slow-mo correctlyFrame rates and over-crankingSequence rates with Adobe Premiere ProAdvanced frame blending techniques with Adobe After Effects Employing the CineAlta system, the Sony PMW-F55 isn’t a cheap buy at $28,990. Many will argue that it rivals the Arri Alexa, except for much less cash. In fact, it has more capabilities in the slow-motion department.The F55 captures a huge 180 fps in 1080p internally, boasting a super clean image. In 4K it is a respectable 60fps internally, with 240 fps 16 bit raw at 2K with no image cropping attainable through the optional off-board recorder. Check out the Sony PMW-F55 at 240 fps: 3. Sony NEX-FS700R Want to shoot slow motion? The following video tutorial will demonstrate the latest professional practices to achieve your own slow motion shots.We view films at 24 frames per second. When played back properly, it’s a standardized approach that provides an “artsy” look to cinematography. High-speed cinematography involves shooting at a higher frame rate than 24 fps, giving yet a more surreal look. You may choose to shoot anywhere from 60 – 18,000 fps, depending on your resolution and budget.High-Speed CamerasFirst, let’s take a look at 5 professional high speed cameras for the aspiring indie filmmakers. Although some cameras shoot in 60 fps, for a ‘true’ smooth slow motion effect, pros would tell you to shoot upwards of 100 fps+.1. The EdgertronicThe new Edgertronic is a huge breakthrough concerning high-speed cinematography for the indie-filmmaker, starting at only $5,495. It’s a specialty super slow-motion camera packing frame rates up to 17,791 with resolutions up to 1280 x 1024!The Edgertronic was developed by MIT-trained engineers looking to make high-budget camera technology attainable for the masses. They originally started a Kickstarter page to launch the product in 2013. Check out the Edgertronic at 500 fps: The JVC GC-PX100 is the most affordable camera with great fps capabilities coming in at $999.95. A time control button lets you choose shooting speeds between 1/80th and 500 frames per second, or from time lapse to slow motion. The downside to shooting at 100 to 250 frames per second concerns the resolution dropping to 640 x 360, and to 320 x 176 at 400 or 500 frames per second.The price is definitely what makes the JVC GC-PX100 stand out. Check out the JVC GC-PX100 at 600 fps: The Sony NEX-FS700R starts out at the modest price of $7,699. Quite a bang for your buck considering the specs: up to 250 fps at 1080 x 1920. By no means a one-trick-pony, the price is a good deal for professional looking slow-mo. With some cropping and a reduced resolution, higher frame rates of 400/800 and 960 fps are also attainable with this camera. Check out the Sony NEX-FS700R at 240 fps: 2. RED Epic-XAt $19,000, you could buy a new car for the price of the Epic-X. All jokes aside, this is a serious camera that crushes the JVC in comparison.

Jalpaiguri (WB): West Bengal Chief Minister Mamata Banerjee today stressed on a permanent solution for the problems plaguing the tea gardens in north Bengal and formed an expert committee to find out a solution. She said that the committee, under Chief Secretary Malay De, would submit its report after going through the problems at the tea gardens, thus help in finding out a solution. “I want a permanent solution for the tea gardens. Nobody has ever thought of any permanent solution regarding the problems, raging at the tea gardens, for ages. Even the Centre has failed to keep up to its promise, made prior to the last Assembly elections, about opening the closed tea gardens,” Banerjee told reporters here at the Uttarkanya. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killed Today, she held a meeting with representatives of the tea gardens. She also held a meeting senior ministers such as state Labour Minister Moloy Ghatak, Arup Biswas and senior officials of her government. The state government also proposed a daily wage of Rs 176 for the tea garden workers pending finalisation of the minimum wages. This year the state government had announced two interim hikes of Rs 17.50 and of Rs nine, taking the daily wage to Rs 159. Meanwhile, the largest tea producing state of Assam, last week, had announced issuing a possible notification on an interim hike of Rs 30, with retrospective effect from March 1 this year, which would take the current daily wage of tea garden workers from Rs 137 to Rs 167. Banerjee also lambasted the culture of strike at the tea gardens and said it finished the work culture there.
