Norsepower makes its rotor sails tiltable to overcome height restrictions in navigation

first_imgHowever, the routes involve navigating under multiple bridges and powerlines which require the technology to have a tilting function. Based on the analysis of the ship’s routes, Norsepower estimates that its technology would be able to achieve a carbon emissions reduction of 25% for this vessel. “We are delighted to be working with SEA-CARGO, not only as they are keen to demonstrate their commitment to maximising the propulsive power of wind to reduce emissions, but also for their cooperation and innovation in making tilting Rotor Sails a realisation,” Tuomas Riski, CEO, Norsepower, said. Preparations for the retrofit on the SC Connector are currently taking place with the installation scheduled for Q4 2020, Norsepower said. “With a growing international focus on reducing CO2 emissions and other gases/particles – the ability to harness wind to generate energy, reduce fuel consumption and emissions is a natural next step for the maritime transport industry,” Ole Sævild, Managing Director, SEA-CARGO, added. The SC Connector, a 12,251 gross tonne (GT) Ro-Ro cargo vessel operates in the North Sea, which allows for some of the most favourable wind conditions for Rotor Sails. Developed in tandem by the two companies, the 35m high and 5m wide Rotor Sails are able to tilt to almost horizontal when required.   The agreement also heralds the installation of the world’s first tiltable Rotor Sail, an innovation that has resulted from the need to adapt the technology to the sailing requirements of the ship.center_img It is a modernised version of the Flettner rotor, a spinning cylinder that uses the Magnus effect to harness wind power to thrust a ship. “Rotor Sails are particularly well suited to Ro-Ro vessels and working with SEA-CARGO to deliver a tilting Rotor Sail ensures we are providing an adaptable solution which fits with particular vessel requirements, specifically demonstrating vessels with height restrictions to benefit from the Rotor Sail solution.” “The goal of this project has been to design more environmentally friendly vessels by combining several existing technologies. In good wind conditions, the sailing hybrid vessel will maintain regular service speed by sail alone.” The Norsepower Rotor Sail is fully automated and detects whenever the wind is strong enough to deliver fuel and emission savings, at which point the Rotor Sails start automatically. Finnish cleantech company Norsepower and logistics provider SEA-CARGO have inked a deal to install two of Norsepower’s largest Rotor Sails onboard the SC Connector, a side door Ro-Ro. It can be fitted on both new ships and those already in operation.last_img read more

Critics dispute Family First findings on day care

first_imgDominion Post 8 Feb 2012Conservative lobby group Family First is using a report from a controversial academic to claim day care is detrimental to children.The group issued today the report that claims spending long periods of time in day care, and away from parents, is detrimental to a child’s long-term development.However, the study, by Dr Aric Sigman, hit the headlines last year in Britain, where it was questioned by experts. Dr Sigman is also behind a 2009 claim that Facebook and other social networking sites cause cancer. He was accused of “cherry-picking” evidence and ignoring that which did not support this theory.Writing in The Guardian last year, Dorothy Bishop, professor of developmental neuropsychology at Oxford, disputed his claims and questioned his credentials.“Sigman ignores or selectively reports evidence for this more nuanced position,” she wrote. “He justifies his one-sided approach to the evidence on the basis that “while open-mindedness has its place in academia, it is a luxury children can’t afford”.Family First commissioned its report, Who Cares, to look at the increasing number of children and infants spending time in early childhood education while their parents are at work.Advocates say staying at home with their children is a luxury that many parents can no longer afford.Hayley Whitaker, early childhood spokeswoman for the NZEI union, said parental policies in New Zealand were “abhorrent” compared to other countries.“We should be able to give people the choice to be at home with their children. They shouldn’t have to feel that they’re forced back into the workforce.”However, there was a lot of evidence to show high-quality early childhood education benefited children, she said.“Everything in moderation, really.”http://www.stuff.co.nz/national/education/6380025/Critics-dispute-Family-First-findings-on-day-carelast_img read more
