airless_tire

via ET Auto : New Delhi: The Goodyear Tire & Rubber Company has released a non-pneumatic, or airless, turf tire as a solution for users, who desire worry-free performance. The tire is available as an upgrade option on Bad Boy Mowers’ Outlaw XP, a zero-turn radius model, with expected availability in early 2018. The technology is part of the company’s strategy to develop maintenance-free technologies for passenger and commercial vehicles, particularly in fleet applications. “As cars become increasingly autonomous, the demand for lower maintenance, longer lasting tires will continue to rise,” said Christopher Helsel, Goodyear’s Chief Technology Officer. “There are still performance and economic challenges to solve before maintenance-free passenger tires hit the market, but we are developing technologies that are getting us closer every day.” Goodyear has been developing non-pneumatic technologies since the 1970s when it participated in the design of tires for NASA’s Apollo lunar roving vehicle, and in recent years in the development of a tire for future missions to Mars. TurfCommand Non-Pneumatic Tire For this new application, the Goodyear TurfCommand with DuraWeb Technology is an optional fitment for the premium Bad Boy Mowers model. Goodyear’s exclusive DuraWeb Technology has been in development for the past few years at the company’s innovation center in Akron, and is being manufactured in the US, exclusively for Bad Boy Mowers. Goodyear engineers and scientists incorporated feedback from field studies that included the Cleveland Metro Parks and with mower dealers, such as Beltz Lawn and Garden Equipment in Akron, Ohio and the… Read more

The World’s First Floating Wind Farm Is an Incredible Feat of Engineering

wind_energy

via Singularity Hub : Wind turbines are a valuable source of renewable energy, but it can be hard to find a good place to put them. They need to be close to a populated area so that transporting the power they generate isn’t too expensive—but they suffer from some serious “not in my backyard” syndrome when it comes to being too close to populated areas; they’re noisy and, though a field of them looks scenic from far away, up close they’re sort of huge and ugly. So why not put them out in the ocean? It’s not a new idea—as of the end of 2016 there were 14,384 MW of installed offshore wind power capacity, the bulk of it in Europe—but what is new is having the turbines float instead of being anchored to the sea floor. Last week saw the launch of the world’s first floating offshore wind farm. Located in the North Sea off the coast of Peterhead, Scotland, the wind farm consists of five enormous horizontal-axis turbines that together can generate 30 megawatts of electricity. That’s enough to power about 20,000 homes. The wind farm is called Hywind, and it’s been in the making for over 15 years, spearheaded by Norwegian energy firm Statoil. Key facts about the turbines and their location include: The turbines are positioned in water up to 129 meters (423 feet) deep (anchored turbines are usually placed at maximum depths of 50m (164 feet)). Each turbine is 253 meters tall in total (around 830… Read more

What’s New In The World Of Construction Technology?

construction_technology

via DH : Rapid urbanisation coupled with an increased white-collar migration to bigger cities has placed the real estate market in the country on the growth trajectory in the last decade. But the soaring cost of construction and the intermittent availability of trained labour has always been a constant problem for its growth. Realising the underlying challenges, the Indian real estate and allied industry have made significant transformations when it comes to construction technology and design aspects to weed out the existing anomalies to keep its growth on track. Several leading developers have already been implementing state-of-the-art construction technology for their ongoing and upcoming projects for a long time. But on the backdrop of recent policy and structural changes, this has further propelled many players to adopt innovative construction technology. Let’s look at three construction technologies that will define and shape the real estate sector in the future: Technology 2.0 The use of pre-cast technology for building urban infrastructure and large urban housing projects is common in cities. Today, the technology appears to be used for the construction of apartments in the urban areas too. Especially developers who are focused on the affordable housing segment or have forayed into the sector recently post the sops offered in the budget are adopting the precast technology. Precast technology ensures quality, clean and speedy construction with lower construction costs. An affordable housing project involves the construction of over 1,000 to 2,000 standard size apartment units; and in different phases, the construction requirements are different.… Read more

New Lightweight Materials Can Expand With Heat

lightweight_material

via RDMAG : Researchers are tapping into the properties of “bubbles” to create a new, lightweight material that expands with heat to fill any given shape. A team from the University of Pennsylvania and the Korea Institute of Science and Technology have found a way to exploit the properties of bubbles to create “microbombs,” a type of material that expands with heat to form microclusters that can fit themselves to fill their physical confinement. The microclusters became extremely lightweight with soft and adaptable boundaries when they expanded to large volumes. “We got our inspiration from how farmers in Japan make square-shaped watermelons by growing them in plastic cages,” postdoc Hyesung Cho said in a statement. The researchers prepared microwells from a rigid material that could not be deformed against the expansion of microbombs and then carefully heated the microbombs to cause them to expand and thin the shell around the bubble without fracturing it. This strategy enabled the researchers to create microclusters with a wide variety of shapes including circles, triangles, squares, pentagons and hexagons and partitions (from single to multiple units per cluster), edge profiles (from round to sharp corners) and hierarchy. They were also able to transfer micro-nanopatterns onto the surface of the microclusters. “The nice thing with our approach is that we can actually inscribe any pattern into the wall inside of the physical confinement, so, when the material expands and softens, it will mold the pattern from the wall into those beads,” Shu Yang, a professor of… Read more

New Affiliates Creates Asymmetric Mountain Cabin In Vermont

cabin

via dezeen: Steep, pointy roofs and square windows that frame views of the landscape figure into this pine-clad retreat in the northeastern US, by design studio New Affiliates. The Turnbridge Winter Cabin is tucked within Vermont’s Green Mountains, on a wooded property covering 65 acres (26 hectares). The design team took cues from the area’s traditional architecture, notably the barns, houses and sheds that seem to “grow on and around each other, as if clustering for warmth”, said New York-based New Affiliates, or N/A. “After the typically informal and loose nature of these vernacular structures, N/A sought to create a design in which regularity is interrupted by slight misalignments and minor asymmetries in the size and placement of architectural details,” the team said. Encompassing 1,250 square feet (116 square metres), the cabin contains living quarters and a painting studio. The dwelling is meant to serve as an “informal, winter-ready getaway”. In plan, the cabin consists of two identical squares that meet at a corner, with the entryway located within the triangular space at the “hinge”. The massing is composed of pointy volumes clad with pine boards placed at an angle. A rooftop deck sits at the centre of the building and helps connect the home to its natural setting. One side of the cabin contains the studio, while the other houses the living quarters. The studio has high ceilings and a clerestory that brings in soft, natural light. The living zone has a kitchen and living area on the ground level,… Read more

Ultra-High Resolution Inkjet Technique Prints Drops Capable of Trapping Light

ink_jet_printer

via the Engineer : Cambridge researchers develop method with potential for medical sensing and investigating interaction between light and matter Inkjet printing, familiar from millions of desktop printers, is the basis for many new techniques in electronics and biotechnology, using the technology’s ability to accurately place small droplets of material to make structures from conducting or semiconductor materials or even living cells. The Cambridge team, from the University’s Cavendish laboratory and Hitachi’s laboratory in the city, have modified this technology so that it can print dots of ink with optoelectronic properties that can trap and harness light. The key to the technique, which the team describes in Advanced Materials, is in reducing the size of the droplets to the scale of the wavelength of light. The co-first authors of the paper, Vincenzo Pecunia, a visiting researcher at the Cavendish laboratory, and Hitachi researcher Frederic Brossard, discovered that a new type of printer developed by Pecunia was capable of this resolution. The printer dispenses ink by a method known as electrohydrodynamic jetting. “Most inkjet printers push the ink through the nozzle by heating or applying pressure, producing ink droplets about the size of the diameter of a human hair,” Pecunia explained. The novel printer instead applies a voltage to the ink, forcing it through a much smaller nozzle and producing droplets 10 to a hundred times smaller than those of conventional printers; the droplets have a volume in the femtolitre range, ejected from a nozzle about a micron across. “Previous efforts… Read more

RoboBee Is A New Drone That Explodes Out Of Water And Sticks To Walls

drone

via siliconrepublic : In a somewhat terrifying but beneficial development in drone technology, researchers at Harvard reveal the latest generation of RoboBee. Picture a drone that can fly, stick to walls, propel itself out of water and safely land at a moment’s notice, yet can fit comfortably in the palm of your hand. This isn’t the description of a terrifying robot from a dystopian future, but the latest generation of the RoboBee drone developed by researchers at the Harvard John A Paulson School of Engineering and Applied Sciences, and the Wyss Institute for Biologically Inspired Engineering. In a paper published to Science Robotics, the researchers revealed that the new generation of RoboBee is 1,000 times lighter than any previous aerial-to-aquatic robot and could be used for numerous applications, from search-and-rescue operations to environmental monitoring and biological studies. Beyond what nature can achieve Thanks to advances in the science of flotation, this multipurpose air-water microrobot can stabilise on the water’s surface before an internal combustion system ignites to propel it back into the air. “This is the first microrobot capable of repeatedly moving in and through complex environments,” said Yufeng Chen, first author of the paper. “We designed new mechanisms that allow the vehicle to directly transition from water to air, something that is beyond what nature can achieve in the insect world.” Designing such a robot at a small scale was no easy feat – because water is 1,000 times denser than air, the wing flapping speed varies widely between the… Read more

Property Management Software and Apps

property_management

via Cooperator : As anyone with a smartphone, tablet, or laptop knows, technology makes life easier in countless ways. The management of co-op and condo properties is no different, with new digital tools emerging all the time to streamline, facilitate and improve ease of use for property managers, residents, and shareholders alike. And all this has changed in a relatively short period of time, evolving quickly over the last decade-and-a-half to a point where digital solutions are a must for almost all property management teams. “Just 10 years ago, property managers kept track of resident and property information on index cards, and got their phone messages from carbon-copy memo pads,” says Michael Mullin, president of Integrated Business Systems, in Totowa, New Jersey. “Today, communications, billing and payments, and maintenance requests all take place electronically. In such a brief time, we have gone from a paper business to a totally automated business – and these once-manual functions are handled via a central property management and accounting system of record.” Much of today’s digital solutions stem from a need for greater efficiency and cost effectiveness by property managers. “In order to satisfy the needs of a property manager today, we have to deliver solutions that automate most back office processes,” says Adam Friedberg of MDS Property Management Software, based in Hauppauge. “If there is a procedure that requires significant manual data entry, the expectation is that technology should be able to drastically reduce, if not eliminate, the cost associated with that process.” For… Read more

To Generate More Solar Power, Put This Material On Glass

solar_power

via Futurity : Transparent solar materials on windows could gather as much energy as bulkier rooftop solar units, say researchers. The authors of a new paper argue that widespread use of such highly transparent solar applications, together with the rooftop units, could nearly meet US electricity demand and drastically reduce the use of fossil fuels. “Highly transparent solar cells represent the wave of the future for new solar applications,” says Richard Lunt, an associate professor of chemical engineering and materials science at Michigan State University. “We analyzed their potential and show that by harvesting only invisible light, these devices can provide a similar electricity-generation potential as rooftop solar while providing additional functionality to enhance the efficiency of buildings, automobiles, and mobile electronics.” Lunt and colleagues pioneered the development of a transparent luminescent solar concentrator that, when placed on a window, creates solar energy without disrupting the view. The thin, plastic-like material can be used on buildings, car windows, cell phones, or other devices with a clear surface. The solar-harvesting system uses organic molecules developed by Lunt and his team to absorb invisible wavelengths of sunlight. The researchers can “tune” these materials to pick up just the ultraviolet and the near-infrared wavelengths that then convert this energy into electricity. Moving global energy consumption away from fossil fuels will require such innovative and cost-effective renewable energy technologies. Only about 1.5 percent of electricity demand in the United States and globally is produced by solar power. In terms of overall electricity potential, however, the… Read more

Paris will get its own ‘vertical forest’ which will Add One Hectare of Trees

green_building

via ZME Science : Stefano Boeri Architetti, an architecture studio famous for designing so-called ‘vertical forests’ around the world, will bring the concept to Paris. The firm won the Marne Europe — Villiers sur Marne competition with a project called Forêt Blanche and Balcon sur Paris. The very first French vertical forest will involve an eclectic mix of buildings, among them a 54-meter-tall tower mainly built of timber. “Vertical Forest is a model for a sustainable residential building, a project for metropolitan reforestation contributing to the regeneration of the environment and urban biodiversity without the implication of expanding the city upon the territory,” a section on the Stefano Boeri Architetti explains. All in all, two thousand trees, shrubs, and other plants will cover the wooden facade of the various residential, commercial, and office buildings. That’s a surface area equivalent to a hectare of forest. So, not only will Parisians enjoy a majestic view, they’ll also breathe cleaner air. A breath of fresh air in the Paris skyline Besides the tall forest tower designed by Boeri, the project will feature the works of Kengo Kuma & Associates (Sora, Le Palais des Congrès), Oxo Architectes (Le Potager De Villiers, Business Home), KOZ Architectes (2 buildings, Archipel), Michael Green Architecture (Peuplier Blanc, Prairie Blanche) and X-Tu (La Ressourcerie, Green Jenga). The first vertical forest was completed in the center of Milan in 2014, on the edge of the Isola neighborhood. The Bosco Verticale towers add some 2.5 acres of lush vegetation (over 100 species)… Read more
