Aug 1, official start of the E&M (Electrical & Mechanical) work for the wind turbine.
According to the monthly EIA report from HEC, there are no problems and all is going according to plan.

By the way, did you know that our Magical Spinney Thing has its own website already? Very secretive and nobody seems to have heard of it before one of my Alert Readers (from down under!) informed me yesterday!

Check out this address and see the Spinney Thing spin on the home page!

Construction programme for the rest of this year:
http://lammawindturbine.hec.com.hk/mreport/html/200506/200506wtemna.htm#ad

This seems to be a standard naming convention for HEC, as there's a site for the Lamma Extension project-in-progress as well:

Anybody got new pictures of the completed wind turbine foundation?

These pictures are 2 weeks old, no more work since then.

Has been work since then...., the central part has been concreted over as of last weekend.

Going back to the post on hub height where the SCMP reported the turbine size had been reduced from 71m to 46m is almost correct. The reporter should have clarified that it was hub height he was talking about and not hub plus rotor radius. The model of turbine they considered came in 3 hub height sizes; 46m, 56m and 70m.

As I can see from Wah Fu (after the heavy haze on the 10 Sept.),The windmill tower has now been erected. It's on the right of the "padoga" and the tower looks rather tall and, when the blades are installed, it would bring huge distraction to people like him who enjoy the scenic view of Lamma.

Such structures would do nothing but screaming at people on the HK side "hey look here, we're harnessing wind energy. How green I am."

At least I'll be able to tell which way the winds are coming, from looking at the willmill across the East Lamma Channel. Laughing

All three blades has already been installed.

[Edit: all 3, not just one as wrongly observed at 0555 in the morning]

I haven't spoken with anyone who lives near any sort of "wind farm", but I've been wondering how far away you have to be in order not to hear the slow "woosh-woosh-woosh" of the blades on a windy day. I expect that blade designs have improved considerably over the years, but I can remember standing about 100 meters from an early model and noticing how noisy it was. With any luck this one will be nearly silent (I hope).

See this thread about the Magical Spinney Thing in the Chinese Forum for photos of MST from the East Lamma Channel (pre-blade a few days ago) and the Main Street (blade-ful, yesterday).

Not bad!

A typical quiet office or library is about 40dBA. Rainfall is about 50dBA, as is a typical home refridgerator. A soft whisper is about 30dBA .

As far as YSW is concerned the distance would seem to be great enough to render it nearly inaudible.

Another press release about the wind turbine has been issued by HK Electric yesterday, just after the tower and the triple blades have been installed this week. It's online at their website:

Hongkong Electric Counts Down to Launch of Territory’s First Commercial-Scale Wind Turbine.

I've also received high-res versions of the accompanying small pictures from HEC and will publish some of them in my blog today.

Spot the difference: view from my roof before and after. I know which I prefer.

Nice shots!

Here's an extreme zoom-in of your 2nd shot, which I've cut out from HK Electric's press release photos.

That hole looks a bit like a bird's nest inside a hollow tree, no?
The two orange-chested, white-crested creatures seem to live there? Is the third one the same species, maybe a subspecies?

Maybe it's a nesting hole for the Vertiginous Flycatcher (Muscicapa dizziensis)- HKE trying to prove their eco-friendly credentials again.

I'd like to take credit for the close up picture but it wasn't me. I own a Canon ixus with crap digital zoom. This is a HK Electric handout pic, those guys can afford long lenses. Shocked

Sorry, my mistake. I've confused your photos in the SCMP wind turbine story with the ones I've received from HKE.

But that great diagram in last Sunday's SCMP of the inner workings of the wind turbine is yours!
So we can ask you loads of technical questions, can we? Wink

Err, I guess. Don't ask me why they call it a nacelle rather than machine housing.
