Off the southwest coast of Norway, a strange-looking wind turbine is quietly making waves—by spinning in reverse. Developed by the Norwegian startup World Wide Wind, this 30-kilowatt floating prototype flips the traditional design upside down. Instead of blades perched high on a tower, it’s anchored from below the waterline, allowing it to sway and tilt with the wind like a sailboat. What makes it truly unique is its vertical-axis system with two sets of blades spinning in opposite directions—creating a counter-rotating effect that boosts efficiency and simplifies mechanics. At just 19 meters tall, it may be small, but it’s packed with big ideas that could reshape offshore wind energy.
Even more fascinating is what this odd design unlocks for the future. By spinning in opposite directions, the turbine reduces the strain on its structure and promises to generate more energy per unit than conventional turbines. It could also allow turbines to be placed closer together, reducing the footprint and cost of large offshore wind farms. Though this prototype only produces 30 kW today—enough to power a handful of homes—the company plans to scale up quickly, aiming for a 1.2 MW version by 2025 and a full-scale 40 MW commercial turbine by 2030. It’s an inventive, low-footprint solution for harnessing wind power in deeper waters, and a glimpse of how innovation might turn the energy world on its head—literally. More
