And the beautiful wind farm is also a vacation spot: People can rent hotel rooms on a nearby ocean platform. Eco-sea tourism?

The farm is called Horns Rev 2, and was commissioned by the Danish utility Dong Energy.

The farm is spread over 35 kilometers, and generates 209 megawatts - enough to power 200,000 homes, Dong Energy estimates.

Made by German company Siemans, the 91 turbines, combined with labor and setup, cost $1 billion.

Here is the platform where tourists can stay - the hotel is the boxy container on the right. It will also house 24 on-site workers for maintenance. According to the New York Times:

Andris Piebalgs, the European Union energy commissioner, said on Monday that a study by the European Wind Energy Association showed offshore wind could be the dominant source of employment in the sector in Europe by 2025, providing 200,000 jobs.


And here is what the farm looked like during construction.

<![CDATA[Energy Ball Turns Your Roof into a Wind Turbine Farm]]> When peak oil means you're paying more to power up your computers than you are for rent, it's time for Energy Ball. Developed recently by Swedish company Home Energy, these cool-looking devices are designed to work in low winds and make very little noise. That makes them perfect for home use, as well as in giant wind turbine farms. But how do they work with that weird spherical shape?

The Energy Ball's shape takes advantage of the Venturi Effect, which usually measures the pressure created when water moves through a contained space. According to Inhabitat:

This spherical Energy Ball takes those principles and uses them to channel air through its six blades and around its generator. This results in highly efficient turbine that can take advantage of very low wind speeds.

I still think the main advantage of this device, aside from how awesome it looks, is that it doesn't make much noise. So you could easily imagine a suburb powered by these things mounted on roofs, spinning quietly in the breeze.

<![CDATA[NextGen Wind Power Goes Local]]> The world needs to figure out its energy problems. Fast. Enter our saviors: a new salvo of gonzo wind power generation systems that break the solution into small, bite-sized parts. From odd, transparent windmills that fit on your urban rooftop (pictured) to handheld devices, wind power might just save us all. And it isn't just the designer "green chic" set that's getting in on the act; Stanford University atmospheric scientist Mark Jacobson did the math in 2005 and it's official: harvesting just 20% of the windpower available above Earth's continents would yield seven times the current global demand for electricity.

Jacobson's study is of wind currents at a 80 meters in the air — right in the wheelhouse for towers that hold big, multi-megawatt wind turbines. But designer Philippe Starck's transparent "Clear Conscience" windmill can fit into the crowded urban landscape and maybe get over the whole "wind turbines are eyesores" criticism in the process.

On an even more local scale — the palm of your hand — HYmini's handheld wind generator is an insanely cute, if slightly impractical device. It requires all sort of finagling to get right and even then doesn't produce a whole lot of juice, but the idea is amazing. Give this gadget a couple generations though and there could be millions of them spinning out power in cool afternoon breezes around the world.

<![CDATA[Airborne Wind Turbines Are Floating Eco-Powerhouses of Tomorrow]]> Wind turbines produce energy by harnessing the wind, and usually they look like windmills. But a new breed of airborne wind turbine is heading into production. Many of them are house-sized and blimp-shaped, inflated with helium and left to churn in the rapid winds that are always blowing 1000 feet off the ground. Others are shaped more like helicopters or ladders. Still others cling to bridges. Someday I totally want one of these floating over my house, powering my Mac while I blog. Check out our gallery of gorgeous, airborne wind turbines.

<![CDATA[Wind Power Sucks But Brain Damage Is Okay]]> I've got some good science news for you, and some bad.

  • Wind power may not be a clean energy source of the future after all. Though Sweden has just built a massive wind farm at sea, most countries have found wind an inefficient and unreliable energy source. [New York Times]

    Why brain damage is okay and MySpace experiences white flight after the jump.
  • Just because you're brain damaged and lose a huge part of your memory, it doesn't mean you don't care. A study published today shows that people with profound memory loss can still empathize with other people and figure out what they are feeling. In other words, you don't need specific memories of your life in order to have social skills. So that whole subplot about the hot, romantic amnesiac on Gray's Anatomy is based in scientific fact, OK? [Scienceblog]
  • Apparently, your race and parents' educational background are the main things that determine whether you'll join MySpace. Researchers at Northwestern found that Latinos prefer MySpace, as do the children of people with less than a high school education. White kids whose parents went to college prefer Facebook. Could mass social network abandonment for Facebook be the white flight of the future? [Northwestern University]
  • Mars doubled in brightness over the past month, and backyard astronomers are taking pictures of its blue-white polor ice caps. Meanwhile, it turns out the sun may be smaller than we thought. [NASA and New Scientist]
