Unless they’ve got stake in a big oil company, the most common reasons people have for opposing the installation of wind turbines is the noise pollution and the risk they pose to birds. But a radically redesigned turbine with flapping wings instead of spinning blades might finally solve both of those problems.
There’s diminishing returns when it comes to adding more blades to a wind turbine and if there were less blades, the turbine would have to spin faster which is apparently not a very good thing when it comes to controlling a turbine. That’s basically why we settled on the three bladed wind turbine system. I think it…
What does it take to move an almost 300-foot-long turbine blade to its final resting place in the ocean? International coordination, huge trucks, and plenty of engineers. And here we thought moving rockets, electromagnets, and space shuttles was hard work.
This is the world's largest wind turbine blade en route to the largest offshore wind turbine in the world, in Methil, Scotland. At an incredible 273.95 feet (83.5 meters) long by 13.7 feet (4.2 meters) wide, the blade had to be transported all the way from Denmark, where it was manufactured—a logistical nightmare.
A thousand feet off the ground, the wind blows brisk and uninterrupted. But how do you build such a tall, thin beam to support a turbine's blades? You don't—you float the generator in a giant helium balloon. The world's first floating commercial wind turbine will soon be hovering over Fairbanks, Alaska.
You're peering down the main supporting tower of Siemens' latest offshore wind turbine—which just happens to be the biggest of its kind anywhere in the world.
There's a reason that wind farms are placed offshore rather than in urban areas—the turbines are typically huge, difficult to erect, and need a solid sustained gust to produce any meaningful amount of current. This prototype, on the other hand, will assemble easily and take up little space as it quietly produces…
Like any piece of machinery, wind turbines eventually wear out and need to be replaced. And in Europe, instead of just salvaging them for scrap when dismantled, they often find better uses like turning them into playground equipment.
How do you set up a 120-meter-tall, 2.3 MW floating wind turbine 12 miles offshore? And once there how do you stand it up? One Norwegian company has devised a simple and elegant solution.
The winter wind in Scotland was angry yesterday, and at the top of its shit list were turbines and trampolines.
I've always found wind turbines to be hilarious, I mean, it just stands in the middle of nowhere minding its own business, spinning peacefully. Not this exploded turbine though—the 328-foot-tall, $3 million (!) behemoth spun itself so fast it EXPLODED IN FLAMES.
Though they deliver clean energy, wind turbines are not exactly pretty. They're tall, grey and sterile. They also interrupt a beautiful outside view.
650 feet! That's as tall as 113 average-height American men stacked on top of each other. That's the size of a 54-story building. In other words, that's huge. But why?
Wind blows. And if there's energy (and money) to be made from this fact of life, we may as well take advantage of it, right? That's what Vestas is doing—and they're using the V164-7.0 MW, a massive, 614-foot wind turbine, to do it.
The Japanese company Logitec, not the same company as Logitech mind you, is releasing this crazy router called LAN-WH450N/GR that has an antenna that looks like wind turbine blades. What the hell? The three antenna design supposedly lets the 802.11n router hit network speeds of 450Mbps.
As you stagger into work and slump over your desktop like one of last night's zombies, engineer Ross Kennedy is having an exhilarating ride atop a 100m-high wind turbine with the best views of Scotland. I'm not jealous...much. [Daily Mail]
I've seen some long trucks carrying wind turbine blades so big that they defy belief. But I've never seen a truck carrying two of them. How can this thing turn without trashing all the other vehicles on the road?
It may not offer the toehold-challenge of traditional rock climbing, but then, traditional rock climbing doesn't usually come with a paycheck. These climbers have been employed to scale huge wind turbines for maintenance, which is green in so many ways.
If you ever wondered how they get up there to fix those giant wind turbines, here's the answer: Helicopters. And absofreakingnuttely crazylala mechanics. Updated with crazy video.
Whales have given us a reliable source of energy for centuries: oil for our lamps, wax for our candles, and of course margarine. All that's required to harvest these lovely fuels is wholesale slaughter of the harmless creatures, and that's starting to go out of fashion, mostly because the whales were starting to go…
