I disagree. It's a polite conversation related to the general theme; trade offs 'viability' of energy vs cost. I think the discussion has run its course anyway.

The mean solar polar hitting the earth is ~200 PW, the total world power consumption is ~20TW, a factor 10000 smaller. I don't think there is any danger of wind power ever de-stablising the climate.Zynerji wrote: ↑08 Aug 2021, 16:09Have they yet studied the climate change caused by removing so much energy from the wind?
One would expect in a macro system that this energy would normally have a purpose and a job to do in the self balanced cycles of nature.
What is the net effect of unbalancing this system by taking this energy out?

It's also worth remembering that the small amount of the Sun's impinging energy that we do make use of isn't taken out of the system.

inefficiency "losses" in the human systems. Although not strictly a closed system (the Earth radiates some of the Sun insolation back out to space, for example), we can assume that it is when considering the insolation energy that is used by humans because that energy stays within the system. Thus the energy is still available to create wind etc.

Yes, all good, but the reality is that the energy being used by humans comes from two sources - the Sun and the Earth's internal heat (that includes nuclear power). That's it. It comes from nowhere else. Using one or the other doesn't alter the balance of the system because that energy was available anyway.J.A.W. wrote: ↑21 Aug 2021, 00:13Sorry to ah, 'rain on your parade' - but - Chaos theory makes a mockery of such simplistic ideas.Just_a_fan wrote: ↑20 Aug 2021, 17:48It's also worth remembering that the small amount of the Sun's impinging energy that we do make use of isn't taken out of the system.

That's not to say that it will be manifest in exactly the same way irrespective of the method of the interaction between humans and the planet, merely that the overall effect will be broadly similar.
The total energy of a system is the total energy in the system. That is fundamental to all systems of understanding. If one suggests otherwise, then all the systems used by humans are fundamentally flawed - including Lorenz's ideas and Chaos Theory.
If the system can be adversely affected by wind turbines, then it can also be adversely affected by burning fossil fuels. Ergo, if you insist that wind turbines are bad for the system, then you must also insist that burning fossil fuels is equally as bad. So which is it? You can't have one without the other.

That's not how chaos theory works. Chaos theory means that we cannot make any accurate (specific, non-statistical) predictions about the evolution of a system sensitive to small perturbations in conditions. It doesn't mean that we cannot make predictions on the average long-term dynamics (as those are not sensitive to small, local perturbations). That's why we cannot make predictions on weather for more than a few days, but we can make predictions on climates ranging over years. It's why we cannot quantify the instantaneous realisation of the flow around a car at some particular time, but we can perfectly well determine the drag coefficient.J.A.W. wrote: ↑21 Aug 2021, 00:13Sorry to ah, 'rain on your parade' - but - Chaos theory makes a mockery of such simplistic ideas.Just_a_fan wrote: ↑20 Aug 2021, 17:48It's also worth remembering that the small amount of the Sun's impinging energy that we do make use of isn't taken out of the system.

And, most importantly, any system is still constrained to the laws of thermodynamics. All the chaos in the world is not going to change that. If you know the amount of energy going in to a system, you know the same amount has to go out (or accumulate within the system). Sure, we cannot predict how the local distribution thereof evolves, but that's not really relevant for the question at hand. All we need to know is that the energy as such is there. The total energy balance is not affected by chaos.

They don't break the laws of thermodynamics.
As they are at their lowest quantum energy (they are at their ground state), they're not batteries. If you add energy then they stop being time crystals.

complexities of solar/upper-atmosphere thermo/radiation frequency reactions - are still poorly
understood (& thereby ignored/dismissed), so to claim that "balance" exists sans "chaos" - is 'bogus'.
