.. you wanted to oust cyber security threats in general, so why leave the car open?

UNECE R155 and R156 are basically the answer to the calls for better cyber security, that it goes along with the greed of car makers is another "feature".

Water + Anti-Freeze = Coolant - the greenish one with glycol

I have had so many dead mice in that bucket when I drained my old timer and left the bucket in the garage it is just the best mouse trap at all.

glycol = sweet, but deadly

.. we all love security and safety, but we are currently on the verge and will likely develop into a trans-human species, that at some point in majority isn't able to servive without devices.

We are currently on the level of the junky-human species.

We have Excel, Question answered, Problem not solved.

Sonst werd ich bÃchtig mÃse, aber bÃchtig mÃse!

And I have actuallyy working experience with (onshore and offshore) wind turbines and have observed the radar scattering of the rotors and I also know how a wind turbine sounds under water.

Under normal circumstances you would be correct, "it's just a wind farm". However in this setting a wind turbine along with the farm is a valuable strategic post also due to it's height for different kinds of military purpose.

- cloak/shadow
- reconnaissance / radar / optical / sonar
- communication
- jamming

And in case of China which has also keen people that when seeing an opportunity they will use it to achieve their purpose.

And on the other hand it's a normal wind farm so it will be economical viable - meaning using a wind farm for the latter purpose as well as getting money out of it is a win-win situation.

And actually I need to set some things straight:

1.) a modern(most like since 2003!?) wind turbine does not engage "brakes", the blades just "feather" it's called a "fan" position

The braking is done aerodynamically, (hint: "pitch" not "stall") Blades
are feathered.

Often there is a break disk which is basically a parking break to engage some kind of form fitting rotor lock bolt:
https://www.youtube.com/watch?...

But the blades actually even then create enough lift for a very mild rotation.

Which is good from a tribological POV, because during high wind speeds the turbine is rocked quite heavy, and there is nothing better for your rotor main bearings than constant rotation, otherwise you get stand still marks that is basically the roller grinding itself into the bearing race way by also producing Fe2O3 by friction and oxygene, which is in turn a very hard abrasive further more increasing the damage propagation.

This type of damage is called "False Brinelling".

The video you were refering to was an old "Nordtank EG" (mid-late 90s) stall machine that is normally braked aerodynamically on the one hand by the "stall profile" of the blade, meaning at certain wind speeds you get stalling and not more lift which is basically not a form of braking rather than a form of power control.

As a braking system there are moveable wing tips that turn 90Â and stop the turbine rather quick.

And additionally to that system stall turbines have a huge rotor brake disk at the high speed shaft of the gearbox, that will if used turn red hot and can actually fail in a way of burning up the brake pads - which is also a typical brake failiure of disk brakes.

When the stall blade however have over time due to accumulation of dirt have changed their aerodynamical properties - you will enter the stall effect at an ever increasing higher wind speed.

Think about where there is stall (turbulence) on an aerodynamical surface, dirt will accumulate - you might have even oberserved that on certain surfaces on your car.

Additionally the tip brakes are operated by a lever actuated mechanism which can get stuck and fail.

Thus resulting in rotor overspeed creating more axial force on the turbine as well as on the blades bending those relatively rigid stall-type blades back till they either break or impact the tower, resulting in an abrupt change of momentum and boom.

2.) Perhaps you can now recognize that I have a certain experience with wind turbines - much from offshore, that also includes having observed how these reflections are looking like on a radar system, and this is why I pointed out the possibility of using these turbines as a dual purpose.

The shadowing and scattering is relevant, depending on your distance to the wind farm.

There is a difference in the level of ease to disable such an installation in a sense to also hinder possible repair.

And basically not all things are targets per se, when you have that approach you will waste precious ammo on not strategically important targets and then you will end up like russia and Taiwan in a direct conflict has no ammo to waste.

In case of russia I'm not totally "unhappy" with the outcome of their wastefulness.

Yeah, great idea, however the cable sucks.

When you read his post and came to this conclusion you my friend must be drunk, because he only pointed out what that meant for Taiwan, not that it should be forbidden.

But I do understand his thoughts as China with it's nationalism cannot be trusted in any sense that this will not have an additional use case.

And greater fools can't even read the text:

Also the P2P distance between mentioned Chaozhou and Taiwan is about 200 km thus with the offshore distance reducing the direct distance to ~100-150 km.

Start at Chaozhou and go east, then after 200 km you will be on Taiwan.

Wind Mills are basically targets:
Well in a conflict then Taiwan also gains leverage, because bascially take a machine gun, grenade or a special missile to the wind mill and it is out of order.

Blast ~1-2m of one blade tip and the rotor will have an imbalance and the turbine will shut down - or in case of continued operation eat up all it's calculated life time in a fraction of time.

Or the sabotage way, use a relativley small distributed amount of plastic explosives at the common downwind side of the tower to dent the steel inwards, the steel there is in the ~1-2" range.

This will weaken the tower so when the turbine is in production it will most likely collapse.

And you can even do sabotage of power cables or attach explosives at the sub surface base structure of the turbine.

Why then ..?
The building actions however are the best way for survaliance to gather geological information about the seabed and land socket of taiwan.

And here comes the most interesting thing, the wind mills can be equipped with communication infrastructure as well as electronic warfare equipment for radar jamming and combined with the ..

biggest threat:
Furthermore the (stacked) rotors (blades) can create a cloak against taiwanese radar surveillance towards the coast, possibly hiding and covering launching and flying cruisemissiles, sea skimming missiles are already hard to detect, now they have an additional cloaked distance. (It can also hide the launch of short range ballistic missiles.)

In turn shorten the response time of the missiles defenses drastically, the defender against (cruise) missiles is already at a disadvantage.

Also Windmills due to their tower height are perfect for doing optical as well as radar survaliance, you can even start to equip the blade tipps with phased array radar and be able to see deep into taiwanese territory.

the tactic to work against this
- enhanced and extended sonar reconnaissance, because basically a sea skimming cruise missile is really loud under water and while those CMs are sub sonic (air) the speed of sound in water is greater.

333 m/s vs. ~1400 m/s

However you should know where to look exactly and here comes an interesting additional problem with the windmill installations, you can also use them to sonar jam and make sonar reconnaissance very difficult.

The most likely attack on Taiwan will be an introductary massive launch of (older) CMs and ballistic missiles in turn draining the tainwanese stock of anti-AA missiles - then putting stronger effort onto "traditional" but even modern gun type AA that however have the disadvantage as covering a much much smaller part of the airspace (point defense)

The massive launch will trigger Taiwan to activate nearly all their radar equipment thus revealing the positions

And combined air raids will then attack the radar positions and launch sites of AA-missiles.

Yes, China will basically carry out the US-style S.E.A.D. this is for sure because in numbers of missile based AA running out, China has the advantage, cheap old stock against expensive new stock as well as the attackers advantage.

Why: because they learn from the best and they have seen what will happen to your invasion forces if they don't.

Thus Taiwan needs to combine:
- satellite reconnaissance, geostationary systems should really be considered
- sonar reconnaissance, submarine UAVs that also must have the possibility to send back data, also surveillance ships are an option
- optical reconnaissance, yes classic towers with telescopes covering different spectra of light
- jamming resistant radar systems

And due to the multitude of weak points all data must be overlayed.

However Taiwan needs a believeable deterrent
Yes in case Taiwan is attacked it needs to fire back at critical infrastructure on chinese mainland as well as the chinese navy - landing craft in particular, because Tainwans defenses will otherwise be worn down and then China can set foot there.

today: must be supplemented by conventional power plants and in turn will reduce the net emissions as well as reduce dependence on energy imports thus in turn reducing market demand for resources and putting pressure on fossil energy prices.
