Figured that... but I was wondering what the ladder was doing on the roof of the tunnel. [bigsmile]

The article in the Intercept is quite informative...

Well the next one they are testing is 500 feet, it is actually easier to build high with tree, then with steel.
But it is very different technically. :)

from the Daily Mail...

"Texans have seen electric bills surge as high as $17,000 after two powerful storms knocked out power and caused a 300-fold surge in demand - as 14million people struggle to get clean water in a 'health catastrophe'.

While most Texans are on a fixed rate plan on which they pay the same monthly amount throughout the duration of their contract, some are on a variable or indexed plan which sees rates vary based on the market."

composite plywood with wood stiffeners? Any articles on the design of this type of structure?

I will keep my eye out in ikea for one of those wooden windfarm units.

The same sort the rest of the country uses.
And for us non Americans what does that mean?
Only plastic PE / PEM outside and copper or PE /PEM inside?

Depends if youre talking hi side (feed) or lo side (drain) and indoor vs outdoor. Hi side interior stateside is generally copper or PEX, but CPVC is used to a lesser extent. Hi side outdoor is usually black steel. Lo lines are usually cast, black steel, or heavy PVC regardless of location being underground. Gas is copper or steel.

The sillcock (spigot, tap, bibb, etc) images you and Alistair posted above are called "frost-free" stateside. They have become a code requirement for new homes in some areas fairly recently but are far less common than a standard external sillcock. Personal preference varies with proponents of each. The frost free variety tend to be rather cheaply made and regularly break from a combination of mineral buildup, cheap materials, and sensitivity to torque. Breaking an external sillcock is nearly impossible by comparison bc theyre heavier brass and less susceptible to mineral buildup, they leak but are easily rebuilt. I upgrade to frost-free when selling to give the appearance of shiny/new but am in no rush otherwise if the sillcock isnt leaking. The current home has three 70+ year old external sillcocks running the sprinklers, one was upgraded bc it leaks and we plan to sell in a few years. The rentals are all decades-old external bc theyre bulletproof. A few decades ago it was a fad stateside among new homeowners to add a shutoff valve and drain external sillcocks but nobody that I know bothers anymore bc there's little risk of freezing/bursting. The northern 1% of the continental 48 might get down ~-15F/-25C for a few days in a cold winter, so there's nothing to worry about unless you're a serious worrier.

An interesting irony and dirty unmentionable of renewable discussion stateside is that the political half constantly demonizing reliable/cheap fossil fuels as evil vs unreliable/costly solar & wind renewables have spent ~70 years pushing for the end of reliable/cheap hydroelectric, and in many areas have succeeded. The rural electric co-op that powers my folks' is up against them now. A local paper mill provided cheap power to the town from ~3 MW of hydro-generators from the 1930s until ~Y2k when it was forced to close and the town bought the site. Now the same outsiders who cost the townspeople half their jobs are demanding the town remove the hydros and buy off the larger grid which would increase prices from $0.025/kWh to $0.12/kWh, and require folks to convert homes from the common electric to fossil fuel heating. Apparently in an area legendary for sportfishing, nature, and green living, the fish are suffering a terrible tragedy that modern dam regulation cannot prevent.

dik I'll see what I can find it is Chalmers who is researching it together with some wood company, but most of the artikels are in Swedish.
The first test tower is only 30 m (100 feet), it is on Björkö in Gothenburg.

And Alistair you are right, you will probably be able to buy one at IKEA ;-) it is modular, maybe not flatpack but as close as possible :)

Best Regards A

Thanks for that answer.

The one I posted isn't cheap and it's solid brass and copper. I have two of them. The Finnish know what they are doing but you pay for it. The normal DIY shop ones are about 50$ but max 300mm long. I needed 500mm.

After years getting shouted at going to collect buckets of hot water inside I thought sod it... And put hot and cold taps in the yard.

I really don't regret it. In fact we use the hot more than the cold.

Here is some articles but I do think they all build on the same Swedish one..
The first have some more pictures.


And here is some friendly advice from Skellefteå, Sweden to Texas.

Best Regards A

PS. In Skellefteå they are building the larges batteri factory in the Europe..

Sorry for my comment. The apology should be coming from me. From context I should have realised the language barrier. I can only speak/write in one language, that shame is mine.

I reacted that way because my reading of the term in multiple other reporting recently. The use of the term "wind mill" is generally associated with people who have a strong political bias against the use of wind turbines as a power source. It has derogatory connotations.

No problem :)
Sometimes when I'm in a hurry I can not bear to proofread everything three times.
It's a little difficult to keep up sometimes.
It takes a little longer for me to check out and understand all the special expressions as well.
But it seems that you English speakers have a little trouble understanding each other sometimes as well.
I am aware of my shortcomings, even if they are few. ;-)
So no hard feelings.

Best Regards A

My opinion - Windmill is really not a completely out of place term for a wind turbine even if it offends some of us engineers.
These may be old school, but you still see them all over remote parts of the Midwest, where the cost to run power to a field is $4.50 or $24000 per mile.

Historical windmills here look like the restored Robertson's Windmill in Williamsburg Va

Redsnake your English is much better than my non existent Swedish or my minimal, but useful German.

Did I do it again ? [lol]
In that case I can blame google translate !!
Yes first writing it, then reading it, then correct what I can find that dose not seem right.
Then reading it again etc..
Proofreading [ponder] or ??
