Like stated elsewhere, the survival of our genus doesn\'t worry me.

It should.

So work harder on persuading people to burn less fossil carbon for fuel.

If that happens it will change our civilisation, but not all that much, and we will still be able to use a lot of energy and look pretty much the way we do now.

Screwing up the global climate even worse than we have so far is a much more dicey proposition.

That\'s about as sound as making judgements about the climate by looking out the
window. Oh wait, you do that, too.

I measured the local ac line period. No judgements were involved.

A simple lowpass or bandpass filter would take out the occasional
noise spike.

Guessing about control theory doesn\'t work.

Actually, it works for a few people. Not many.

Just followed an interesting lecture on robotics with real examples on

Nice channel, all day long science today with so many subjects.
There are a million control systems in your body.
If you have an open mind you can see and feel how those work.

As to amplifier, you can increase Q of a tuned RF circuit by adding negative resistance
resulting in less bandwidth and more output.
above a certain level it will start oscillating.
(example tunnel diode oscillator)
There is also the super-regenerative receiver, oscillates, but it radiates.. positive feedback

Okay, so it didn\'t fly apart, it just bent in two places and caught
fire. That was last week...

There\'re a bunch of videos of burning wind generators. It\'s usually caused by a failed subsystem, like the brakes. When the topmost unit burns up and parts fall off, the assembly becomes unbalanced and the whole thing flies apart. I suspect that\'s what happened in the video. You\'ve got to watch for idiots with an agenda and their videos of just a small fraction of the whole story.

Other people care about their kids. They may not take kindly to actions on your part that threaten their long term survival.

I care about my kids, potential grandkids, other family & friends and their
offspring, and humanity in general. I don\'t want them to suffer, and I don\'t
want to die believing that they will have to suffer. But since human life will
eventually die out, there will be generations of humans that suffer from
increasingly unliveable conditions. Question is, how far into the future do I
care? If humans make it until the sun explodes in a few billion years I\'d count
that as a pretty good success, so I don\'t care. If it happens 20 years from
now, I\'d be pretty upset. So somewhere between these two points in time I stop
caring. And I\'m pretty sure \"our genus\" will make it that long. Maybe a few
preppers who haven\'t run out of ammo and diesel until then.

I still fail to see how such a thing happening is an argument for Jan\'s
proposal that we can solve all our problems with technology. The most
interesting technology question in this context is, why did they take a video
when a still image would have sufficed? The only think moving is the windshield
wipers of the car that the video was shot from.

Successful species do die out, but only because they split into different species who exploit different environments.

Humans are a successful social mammal - rather more than naked mole rats, who are another. The different environments we might successfully exploit could include other planets, so your point of view is rather narrower than it ought to be.

> Question is, how far into the future do I care? If humans make it until the sun explodes in a few billion years I\'d count that as a pretty good success, so I don\'t care.

It\'s highly unlikely that any human descended species would look all that much like today\'s humans then. Physically we are well set up to be cursorial hunters, which isn\'t what most of us have been doing for the last few thousand years.

The sun isn\'t going to explode, it\'s just going to get progressively large, and surviving that would be an engineering problem. Boosting the earth into a higher orbit is a least a theoretically viable way that creatures like us could continue to survive through that.

If it happens 20 years from now, I\'d be pretty upset. So somewhere between these two points in time I stop
caring. And I\'m pretty sure \"our genus\" will make it that long. Maybe a few

I wouldn\'t pick preppers as likely long term survivors. Not enough imagination.
