Break It To Make It: These Two Women Are Helping Build The Wind Turbines Of The Future

Tomas Kellner
March 06, 2019

For the last two summers, Claire Stortstrom and Kristen Hanrahan have set up shop for a day in an empty office in downtown New Orleans. The two young GE engineers arrived laden with stacks of sticks, paper, cardboard and glue, and trailed by a throng of 60 middle-school girls eager to learn about their job: building and testing the blades for some of the largest wind turbines on the planet.

Cheers! This California Winery Gets Its Juice From The Wind

The Scheid family has been farming grapes in the lush agricultural region of California’s Salinas Valley for almost half a century. They own 12 estate vineyards on a 70-mile stretch just miles from the ocean. Every year, they harvest enough pinot noir, chardonnay and other varieties from their 4,000 acres to fill more than a million cases, wines that find a home on the shelves of national retailers like Kroger and Whole Foods, as well as a multitude of restaurants.

She Has Her Finger On Power’s Pulse: GE’s Vera Silva Talks About Building The Nervous System For Energy And Getting The Electric Grid Truly Ready For The 21st Century

Operating a massive power grid is a bit like riding a bike, says the Swiss national grid operator Swissgrid. It’s easiest if you’re on a level surface, but things get trickier going uphill or downhill — or, in the case of the grid, when there are fluctuations in supply and demand that require power plant operators to either spin their turbines faster or ease off the throttle.

Winds Of Change: GE Combines Grid, Renewables Units Into A Renewable Energy Powerhouse

Germany’s huge new offshore wind farm Merkur is an awesome sight in its own right. But it’s also a great illustration of why GE’s decision to combine its Renewable Energy business with its Grid Solutions unit, announced today, makes a lot of sense.

A Towering Achievement: This Summer In Holland, GE Will Build The World’s Largest Wind Turbine

Rotterdam’s famous windmills, cube houses, and tulip gardens will soon have to compete for attention with a towering newcomer. GE announced plans this week to erect a prototype of the world’s largest wind turbine, the Haliade-X, on the city’s outskirts. The turbine has a rotor that measures 220 meters in diameter — twice the length of a football field — and stretches 260 meters from its base to blade tips. That’s nearly three times the height of New York’s Statue of Liberty, measured from the ground to the tip of the torch.

GE cast the blades in a foundry, but Avio Aero, which wanted to go after the emerging TiAl market, bet on 3D printing. “We could see how difficult it was to make these blades,” Abrate says. “But we had positive experiences with 3D printing on a military project.”

India Needs Plenty Of Wind And Solar Power To Meet Renewables Goals. This Hybrid Farm Can Harvest Both.

You won’t find the village of Borampalli in any major guidebook. Located in an arid corner of Andhra Pradesh, a state in the southeast of India, the place is little more than a cluster of homes ringed by stony fields and steep rocky ridges that protrude from the ground like the bony plates on the back of a stegosaurus.

Shades Of Green: Wind-Battery Hybrid System Debuts In Ireland

Brendan Coffey
November 26, 2018
In a remote corner of western Ireland known for producing jockeys, rebels and poets, an evolution in renewable energy is taking place. GE is putting the final touches on the world’s first commercial wind project with integrated power storage. This means that even when the breeze isn’t blowing, the project will be contributing power to the grid. The solution is an important step in adding more wind into the energy mix by stabilizing its power supply.

All That Jazz: GE Opens Wind Turbine Blade Test Center At NASA Rocket Factory In New Orleans

Tomas Kellner
November 14, 2018
There are few places in the world like NASA’s rocket factory in New Orleans, where the U.S. space agency and its contractors are building the Space Launch System. It’s the most powerful rocket ever designed — and may one day take astronauts as far as Mars. Known as the Michoud Assembly Facility, the plant covers an area equal to 31 American football fields, including several soaring high-bay areas where workers stack silver and orange rocket segments like Jenga blocks.

Wind Turbines Of Change: This New Wind Turbine Platform Is Creating Fresh Opportunities For Renewables Around The World

September 24, 2018
The capriciousness of the elements is a perennial challenge for intermittent renewable energy sources. The wind doesn’t always blow, and the sun hides behind clouds. While engineers may not be able to command the weather, they’re getting better at harnessing as much wind as possible by bringing wind turbines to blustery places where logistically it could not have been done before. A profitable wind farm nestled in a Japanese mountain valley or rising from the slopes of rugged Greek hills is now possible because of the combination of new technologies and skilled service crews.
