I thought we'd take a little field trip today! And maybe learn something about one of the alternative energies. As some of you know, HB is an electrician....not the kind that wires house though. He works on big industrial projects and right now he's working on a project that will eventually build 84 new windmills.
This project is being done about an hour and a half north of where we live, on a privately owned ranch. Here is one of the areas being prepped for seven new towers. The elevation ranges between 3500 and 5500 feet above sea level. All the roads had to be built especially for this project.
That item in the foreground is a drill used to imbed fourteen 30' long steel rods into the bedrock where they are held in place with epoxy, and anchor the windmill towers to the earth. I think this shows some of the wild beauty of this area....and also looks somewhat like a scene from a science fiction movie about another planet.
The photo above shows the first two towers at the Pine Tree Wind Farm. That is a 150 ton crane, and the parts of another windmill are all laying around waiting to be assembled.
This shows the assembly of the rotors. Each blade is 120' long and each blade weighs 12,000 lbs. The hub in the middle weighs approx. 15,000 lbs and the whole rotor assembly is approx. 50,000 lbs when put together. So these aren't the windmills you might see on your grandpa's farm!!
It takes two cranes to initially hoist the blades into place and the coordination of the lift is very tricky. This shows some of that procedure. There are actually two men on top of the tower on the left. They communicate with the crane operator with walkie talkies so they can direct the placement of the rotors. The towers are 213.3' tall. Not exactly where I'd want to be standing!!
This is a photo looking up at a completed windmill....the rotor diameter is 252.6' and when the system runs the rotor spins one revolution every two seconds. Each windmill produces 1.5 mega watts of power.
So that's where HB spends his days.
