This is how you install the most powerful wind turbine in the world

Enercon‘s E-126 turbine towers 125 meters high and can generate a staggering 7.58 MW of electricity. As of 2012, 147 such turbines have been installed all over the world. This video shows the non-trivial process required to install and operate an E-126 turbine — the┬ámost powerful in the world.

To counter the huge forces exerted by the turbine’s blades, the E-126 needs a solid, 2,500-tonnes foundation. Though very expensive, priced at $12 million without installing costs, large turbines are considered more cost-effective, if the wind conditions are ripe of course. You’d need to install three turbines to get the same output, which means you need more crew members and more labour in the foundation and installing work. Manufacturing per unit KW is also cheaper.

Because it’s so big, the E126 only turns 12 times per minute — ample time for birds to dodge the revolving blades. Birds killed by wind turbines are a big concern, but not with the E126. Even one single E126 can provide enough power to meet the needs of an entire small town. Engineering at its finest!

    This article has problems:
    – No way the blade turns at 12 times per second. Way too fast.
    – If the blade turns at 12 times per minute, the blade tip is moving at 108 kph, easily fast enough to kill birds. Even at 12 times per hour, that’s still fast enough.

    No, the blade tip velocity is high enough to confuse birds flying in thermals and kill them.

    Instead of hypothesizing, we should collect real data from the ground, because the height is large, we should check larger area on ground for dead birds. When falling from height, dead birds may drift many meters away.

    High altitude wind is solution for the bird problem, it also gives more capacity factor.

    Eagles too.

    And fossils kill 17 times as many birds as wind.

    Let’s add that bird populations worldwide double every year, then die back to about the same.

    Otherwise we would be knee deep in birds.

    The niche is full.
