Thanks, Elizabeth, for this story. The concrete-composite combo makes a lot of sense. We've covered the use of corrosion-free composites used in pontoons and docks, and combining it with concrete clearly gives stability and weight where needed, as well as lower cost.

I can see the platform surviving a huricane, but not so sure about the composites.  If they build them like the oil rigs, maybe they will only need to replace the blades after big (cat 2+) storms.

Offshore Turbines

From past articles I've done, my understanding from suppliers is that offshore turbines (especially in North America) isn't gaining ground like it is in Europe and other places where available land is a factor. Maintenance costs are high for offshore, for example.

@apresher: In anywhere maintenance cost is considered as high most of the time.

@a.saji: It is obvious to most, that the maintenance costs of offshore devices like this will be higher than the terrestrial based versions.  Of course, they may be offset by the fact that no costs at all will be incurred by land rental or purchase.  I personally would wonder if wind turbines in the open ocean would be better served using Darious rotors, for reduced costs of maintenance and safety.  Terrestrial based turbines with the generators at the top are maintained by people climbing them and doing the maintenance.  This might be easier with the Darius rotor in the open ocean, because the generator and gears are at the bottom.  This would also lower thecenter of gravity, making it more stable on a floating platform.

Thanks for that information, Jim S. I wasn't exactly sure how the floating system works but that makes a lot of sense. I always thought the idea of a "floating" structure was a bit of a misnomer and there had to be some anchorage in there somewhere! So it is true.

Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
