New omnidirectional wind turbine can capture wind energy on building rooftops

first_img Image: Katru Eco-Energy Citation: New omni-directional wind turbine can capture wind energy on building rooftops (2011, May 16) retrieved 18 August 2019 from https://phys.org/news/2011-05-omni-directional-turbine-capture-energy-rooftops.html More information: via New Inventors (video) Sureshan, who has been in the business of designing mechanical systems (such as the first hybrid rooftop solar air-conditioning unit to go up on a commercial building in Queensland, Australia), for over 25 years, says he began working on the design after spending a lot of time working on building rooftops and noting how there was a lot of very nearly constant wind flying around, and thought there ought to be a way to capture it and put it to good use.After studying then current ideas for capturing wind, Sureshan hit on the idea of building an enclosure of sorts, or shroud, with airfoil blades for “walls” that allowed air to travel inside the chamber, but because of the angle, would force it to flow upwards inside the chamber, rather than allow it to pass through and out the opposite side; all that wind (or at least 87% of it) would then flow upwards towards the horizontal blades connected to the turbine, which would spin, producing electricity. The result is a wind turbine that has just one moving part, is much quieter than most other turbines and doesn’t harm birds because they are too large to fit through the sidewall blades. It looks pretty cool as well. This document is subject to copyright.

It is considered to be a vertical wind generator, as its main rotor shaft is arranged vertically, and while it’s not the first to incorporate such technology it is unique in that it has horizontal blades, and because it’s likely the first to have been tested by Honda Formula 1’s racing team to validate its unique ability to capture wind and hold onto it, rather than letting any escape out the opposite side. © 2010 PhysOrg.com Smart wind turbines can predict the wind The Katru Eco-Energy website indicates the IMPLUX wind turbines should be ready for sale by mid 2012. (PhysOrg.com) — Katru Eco-Energy, headed by founder and inventor, Varan Sureshan, has developed a new kind of wind turbine meant to capture the winds that fly in all directions atop big buildings, and unlike conventional devices, the IMPLUX, as it’s called, can capture wind from any direction as it stands; meaning without having to be repositioned or pointed. The IMPLUX achieves this feat by means of horizontal turbine blades that sit atop a vertical axis and are turned by wind that is pushed up through what Sureshan calls a “fluid dynamic gate.”last_img read more

Best of Last Week – Philae lands on a comet new way

center_img Another team saw some clues revealed about the planets interior—reexamined, decades-old Voyager 2 data offered evidence of the possibility of an unusual feature hiding deep within the planet. Meanwhile, researchers at Arizona State University found that magnetic fields frozen into some meteorite grains were telling a shocking tale of the birth of the solar system. They suggest that shock waves moving through the material surrounding the early sun had a major impact on how the solar system was formed. And another team working with X-ray telescopes found that a black hole may be a neutrino factory—specifically, the black hole thought to be at the center of the Milky Way galaxy. If the findings prove true, it would be the first time that neutrinos have been traced back to a black hole.In technology news, one team of researchers at the University of Texas announced the development of a lighter, cheaper radio wave device that could transform telecommunications—it’s a radio wave circulator that is both smaller and more efficient than those currently in use and could be used to potentially double the amount of useful bandwidth. Meanwhile, another team working at VTT Technical Research Centre in Finland demonstrated a new technique for generating electricity. In unrelated news, two teams of researchers have confirmed what many have suspected: that a healthy diet is good for the kidneys—and it can even help reverse some cases of kidney disease. And finally, if you’re wondering if smoking weed your whole life might be having an impact, a recent study showed marijuana’s long-term effects on the brain—like smaller brain parts and increased connectivity between other brain areas. They report that it appears likely that there are different impacts depending on when smoking started and how long it has been used. © 2014 Phys.org (Phys.org)—It was a big week for space science, topping the news of course was a European spacecraft landing on comet 67P/Churyumov-Gerasimenko. The spectacular achievement by the washing-machine sized Philae probe was a cosmic first in many ways and resulted in very good data being sent back to Earth before it went silent due to its batteries dying prematurely. Researchers studying Uranus were kept busy as well, as one team was thrilled by extreme storms spotted in the planet’s hazy blue-green atmosphere.last_img read more

NKDA launches drive to keep stray cows off roads

first_imgKolkata: New Town Kolkata Development Authority (NKDA) on Tuesday launched a drive to catch stray cows. The owners of the stray cows will be fined and NKDA authorities feel that the drive will make the owners of the cattle aware that they should not be allowed to roam about aimlessly on the main thoroughfare.Earlier, the New Town Kolkata Development Authority (Amendment) Bill 2018, which empowers the chairman of NKDA to pass orders of seizing cattle that stray in public premises in New Town, was passed by the Bengal Legislative Assembly in March 2018. The notification for the amendment has already been released by the state Urban Development and Municipal Affairs department. Also Read – Heavy rain hits traffic, flightsThe list of animals that can be seized under the order of the NKDA chairman Debashis Sen, includes any cattle, horse, pig, dog or similar animal or bird, if found straying on public roads.It may be mentioned that in order to keep the seized animals with care, a cattle shed has recently been constructed in New Town. The cattle shed has facilities for feeding the animals, a small administrative office and an open ground for the cattle to graze.The area, spread over 3 acres, is located in Action Area 1D and steps are being taken to frame draft rules regarding fees and procedure to be followed, in confining the animals and releasing them subsequently.

Stray cows pose a serious threat to the smooth movement of vehicles on Biswa Bangla Sarani. Road accidents often occur when the drivers try to save the straying animals. The Biswa Bangla Sarani has witnessed a handful of such accidents in recent times, leading to injury to both cattle and people.The worst accident occurred on October 26, 2017, when six-year-old Deepshika Chakraborty, her father Pravat and his colleague Goutam were killed, after the motorbike they were travelling on skidded off the road, trying to avoid cows near the Akankha Crossing.last_img read more
