The 109,000 HP Wärtsilä-Sulzer RTA96-C diesel engine is the largest and most powerful, but at 2000 tonnes, any warship it’s attached to is going to have trouble outmanoeuvring jellyfish, much less torpedoes.
A Japanese company called Ibasei has developed a compact underwater turbine generator that could be a silver lining during natural disasters that cause intense flooding. The Cappa looks like a small jet engine from a plane, but it’s actually designed to harness rushing water and turn it into free energy.
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.
When complete, the Vestas V164 is slated to be the world’s largest and most powerful wind turbine on the planet. Standing 135 metres tall, with a diameter spanning 164 metres, the turbine to generates eight megawatts of power. This is no child’s pinwheel. In fact, it cranks out enough juice to power a whole neighbourhood.
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 skyscrapers.
How do you inspect a wind turbine? It’s actually a pretty tedious process that takes around four hours and involves someone standing out in a field, stopping the turbine and photographing any problems through a powerful telephoto lens. To make it infinitely easier, GE made a Spider-Man-like wall-climbing robot.
We’ve yet to discover a perfect source of clean energy, and while wind turbines come close, many people still consider them to be an eyesore. But we don’t think anyone would complain if they all featured the beautiful spinning helix design of the Hercules turbine.
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. This 100m tall, $US3 million(!) turbine spun itself so fast it EXPLODED IN FLAMES.
