Eureka! A Whisper-Quiet Wind Turbine Based On Archimedes’ Screw
When they’re standing out in a field, miles away from crowded urban centres, the sounds made by a wind turbine’s blades aren’t a big issue. But when they’re perched atop a downtown building, they create noise pollution that’s hard to ignore. A Rotterdam-based company might have found a solution with a unique turbine design partially…

Watch These Wind Turbines Shoot Incredible Lightning Into A Storm
We all know wind turbines can produce electricity, but have you seen them produce lightning? When scientists trained high-speed cameras on a wind farm in Spain, they captured lightning bolts shooting out of the wind turbines. Tall structures like towers can initiate ground-to-cloud lightning, but ever-spinning wind turbines present a unique challenge.

Monster Machines: World’s Biggest Wind Turbine Is As Broad As An Airbus 380
The first commercial offshore wind turbine that Siemens created 30 years ago had 5m long blades and produced a paltry 30kW. A lot can change over three decades. The company’s newest offshore model isn’t just the biggest in the sea; it’s the biggest anywhere.

Tiny Rooftop Turbine Could Make Urban Wind Farms A Reality
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 more easily than an Ikea bookshelf and quietly produce kilowatts atop…
