Construction of the largest land-based wind turbine ever built in the United States. “Reaching New Heights” uses a combination of time-lapse footage, aerial photography and behind-the-scenes action shots to document the steps involved in building MidAmerican Energy’s first concrete wind turbine tower, located at the company’s Adams wind farm in Adams County, Iowa. At 379 feet from ground to hub, the concrete turbine is more than 100 feet taller than its neighboring turbines constructed with steel towers.

what power of this one ?

stop all gas drilling. It makes us sick. It destroys our water. Methane from natural gas is 100 times worse for global warming than CO2

i'm sure a VAWT would require less concrete and less structural engineering to keep it stable. VAWTs turn even in low wind and can be designed to have a maximum speed because the blades become self braking over a certain airspeed.

Обалденно/Awesome просто круто, рад за ребят.

Concrete will make demolition faster when fake environmentalists finally admit what a wasteful blight they are. https://www.google.com/search?&q=wind+power+backlash+scenery

These look very much like the smokestacks wind geeks claim to find ugly. Of course wind geeks don't respect nature that much. They just need a "green" angle to push their inefficient eyesores onto rural scenery, and bribe landowners..

Concrete is not exactly the most environment-friendly of products.
-
Why were not slip or climbing forms used, rather than cast in place?
-
Why are there so many vertical base restraint cracks in the site precast concrete tower segments? Also, with 554 CY of pumped concrete in the base, why was there no thermal control?

JUMP!

That's an awesome vid, thanks for sharing! :D
-
What would be the advantage of making a concrete tower to making it in steel?
-
Soundtrack source please :)

What is the payback of a concrete tower wind turbine? How much extra height is achieved this way? Extra MW? Seems like a lot of extra hours spent in construction. I wish the video had provided additional information
-
So many details... except the ones that matter like cost to build and power output.
-
This is super cool! I'm Happy that this is taking place in Iowa!

How long does it take for the turbine to make enough energy to account for the energy used to make it?
