Comments Off on Vestas shakes up wind power with a 12-blade turbine tower

It’s expensive to transport wind turbines , which adds to the cost of wind power . Seeking to bring those costs down, Danish wind turbine company Vestas decided to tack on more rotors to get the most out of a turbine tower. They’re currently testing a multi-rotor design at the Technical University of Denmark that has four rotors and 12 blades. The company announced earlier this month on Facebook that their new turbine generated its first kilowatt hour (kWh) of power. The multi-rotor turbine doesn’t have the three blades typical on most wind turbines, but 12. The turbine being tested has a ” tip height ” of 74 meters, or around 242 feet, because the testing site restricts tip height to 75 meters. Vestas is using 1990’s refurbished nacelles (or the covers for ” working parts ” of the wind turbine) to explore the concept. Related: Giant turbine blades could bring exponential growth to U.S. wind power market One potential drawback of the multi-rotor design is that if one component breaks or stops functioning, Vestas would have to make rapid adjustments so the rest of the turbine could offset the flaw. Real-time monitoring would be therefore crucial. CleanTechnica speculates that could be why the company is using refurbished parts rather than creating new parts for the new multi-rotor turbine. In their Facebook post announcing the first kWh, Senior Specialist, Electrical, Load & Control Erik Carl Lehnskov Miranda said they planned to keep testing ” various software functions .” Vestas added, “…by 2020 as much as 10 percent of the world’s electricity consumption will be satisfied by energy from the wind … [and] we have the confidence to say that wind power is an industry on par with coal and gas.” Via CleanTechnica Images courtesy of Vestas Wind Systems A/S

Comments Off on New LEGO headquarters in Denmark modeled after its famous toy bricks

LEGO Group plans to add a new headquarters in Denmark , and the global hub will be designed by architect C.F. Møller , also from Denmark. The building itself will be home to a collaborative work (and play) space, according to the company’s mission, while the exterior grounds will consist of a park open to the public. With influence taken straight from the famous toy bricks, Møller’s design will include a LEGO People House, a colorful atrium, and architectural features built right on top of recognizable LEGO elements. The new office complex will be located in Billund, Denmark and will serve as a hub for the company’s global headquarters. To create the design, the architect will take cues from LEGO employees who contributed their input en masse, and the resulting office space will represent the two major aims of the toymaker: work and play. The LEGO People House is an informal space, where employees and visitors “can be physically active and socialize, both during and outside working hours,” according to Claus Flyger Pejstrup, Senior Vice President at the LEGO Group, and responsible for the LEGO Group Headquarters in Denmark. Related: First bricks laid for BIG’s LEGO house in Denmark The LEGO Group employs more than 17,000 people around the world, of which more than 4,000 LEGO® employees of 35 nationalities work in Denmark, spanning product development, marketing, manufacturing, engineering, quality and various other functions. The new building will be the company’s main hub in Billund, spanning 52,000 square meters, and will incorporate energy efficiency features as well as numerous green spaces. “We want a distinct office building that clearly conveys the LEGO values, and which truly expresses the creative, innovative culture of our company,” said Pejstrup. “I am very excited that we can now present our vision for this new building, both to our employees and to the community.” + C.F.

Burlington, Vermont Now Runs on 100% Renewable Energy

Comments Off on Burlington, Vermont Now Runs on 100% Renewable Energy

Burlington, Vermont, a city of 42,000 people, is now powered by 100 percent renewable energy sources – most of the time, at least. The city set itself this target around a decade ago, and recently completed the transition to renewables when the Burlington Electric Department bought a 7.4-megawatt hydroelectric system on the Winooski River near the city’s border. The hydro scheme joined the city’s existing wind-powered systems  and a biomass facility, which processes leftover woodchips from the local logging industry. The only time Burlington may have to draw on nonrenewable sources from now on is if there is not enough wind.

Comments Off on Swedish Strawscaper Harvests Energy from the Wind With a Kinetic Hair-Covered Shell

Every once in a while an idea comes along that is so unlike anything before that it defies reference. Take Belatchew Lab Architecture’s Strawscraper, a skyscraper covered in hair that can harness the energy of the wind. The building looks as though it belongs at the bottom of the sea, with its long anemone-like hair, but its technology is planted firmly on the terra firma of the future.
