Re: “Bitcoin mining operation shipping containers tumble in high winds

The pictures of the leaning containers vs the lamp post on the right may have had more impact if the lamp post was actually in the picture. Probably a bad crop job by CS Indy. Nothing in the picture is plum or level. Whether the containers are actually leaning is still a question, lamp post or not.

As a photographer, I can say that shooting from ground level upwards always creates a leaning perspective illusion. Specific perspective-control lenses that shift the optical axis to compensate for the problem are used in this situation. Shooting across a squared object will never show if the subject is plumb or level. Even the concrete wall, the lines we know are plumb, level, and at 90 degrees do not appear so; they show perspective distortion making it seem seem skewed. It also seems the wall and containers are not parallel, creating further distortion.

That said, it is obvious that this stacking could have done much better - having a wind tople them is proof positive. As these shipping containers are designed to be stacked and be stable aboard ship at sea in less than perfect conditions, it is obvious that Chen did not stack them properly. The twist-lock stacking pins are not in evidence and should have been used. https://www.atscontainers.com/en/Products/…. That begins with a solid, flat, foundation, rather than ground-stacking willy-nilly. The fact that the foundation was not prepared properly is evidenced by the offset height of the various stacks.

Re: “GOP elites helped create climate skepticism. They can undo it, too.

Let's just put it this way: The constant false attribution of things like wildfires and hurricanes to climate change does not help the cause of climate awareness and change. Every instance of exaggeration gives energy and proof to the climate skeptics. The base may respond to shrill hyperbole but just gives your enemies ammunition.

Editors may want to put this article in editorials or opinions section.

Re: “City says steady drone of cryptocurrency operation won't be prosecuted

If the city were to sample all areas of the city, with just traffic noise, the city would most likely find that the noise limits they have in the city code are not achievable in many parts of the city. The city would also find those areas cannot be mitigated, exposing the city to lawsuits for not enforcing ordinances. Pushed hard enough, especially when the measurements are so close to the limit, the city may choose to change the limits rather than greasing the squeaky wheel.

Mr. Becker says testing that averages the readings isn't valid. Sound level meter readings all are averages over a given sampling time - whether it is a couple milliseconds, a second (usually the slow setting on dB meters) over an hour, or over a day. The other problem in taking this to the prosecutor, is the ordinance does not specify the amount of time the level has to exceed the values in order to make a case. One hour? One Minute? One Second? An example is a dog barking. How long must a dog bark to become a nuisance? Most consumer level meters are not able to register a dog barking since it is a transient sound lost in the constant averaging of the single-reading meters.

Which segues into manit0id comments, while decibel meters may seem a sharp sword, they are actually a blunt instrument that are very often misused and results misinterpreted.

To address Nimrod Weber's comment about bringing it to District City Councilman, no doubt they are aware of the issue, though without being bombarded by letters, may not feel the need to do something. The something they may choose to do may not be the something you wish them to do, however.

Per Allen Bishop's comment, there are a lot of taxes from electricity, and property flowing into CO Springs coffers, but implying a payoff, well...

One can easily graph sound over time. One can use Studio Six Audio Tools SPL Graph (iDevices) and do some 3-d graphing of sounds - frequency vs amplitude over time, and with a calibrated mic (iTestMic), one could get close to standard measurement. It might be worthwhile to make the small investment needed, and take a series of 24-hour measurements to help the powers that be understand the problem. Council understands graphs.

But again, without the ability to measure ambient noise without the plant in operation, one will be largely unable to say how much of the noise they hear is coming from the plant. The city has not, as far as I understand, done those measurements, and as has been pointed out, not done a sound-over-time study.

As I have said before, this is going to be a touch row to hoe. Goof luck, and I do hope you get the outcome you wish.

Re: “Bitcoin mining operator struggles to comply with city noise ordinance

re: Dwight Fairbanks -What a waste of electricity.

"What does a million dollar a month; a MILLION dollar a month electrical bill; what, what if anything at all; does that contribute to Colorado Springs; or Colorado for that matter.

Or anywhere?"

Well, 1) The plant is no longer an empty hulk 2) The plant pays property taxes 3) Colorado and CS collect tax revenue on the sale of electricity 4) The plant has employees (minimal number, I assume, but still jobs and income taxes)

The BC company seems to be making money, and some of that inevitably flows into the CS economy.

Think of what large business - or Google, Apple, etc. server farms do to power consumption what benefit to the local economy.

None of that is green. That's another question entirely.
Raising property taxes? Red Herring. Parking rates? Really?

One can find fault with any business.

Re: “Bitcoin mining operator struggles to comply with city noise ordinance

As I asked before, how much of the measured noise exists without the BitCoin plant in operation vs with the BC plant in operation. Taking a 79 hour measurement on the street does not take into account existing ambient noise. Dogs, doors, and planes make a noticeable difference. Wind turbulence around the house, and an air conditioner on a hot night?
Making a criminal case will be t o u g h. Defending a 50 dBa limit will be similarly tough, and will be challenged as part of the proceedings. Anyone ever determine where that number came from in the code?

CS should sample a number of points in the city now they have their whiz-bang gear. (training?) Getting those other numbers from other quiet and commercial/residential boundaries will tell the tale whether the standards are actually achievable city-wide. Unless CS write noise regulations per locale, which would be completely unworkable, they will have other challenges on their hand.

In my town, I have measured 60dBa on a sunny afternoon with only a breeze blowing lightly through the trees, and the odd car driving by at 25mph 100' away.

Let Chen keep working on noise abatement, and pray this never sees the inside of a courtroom. It would likely be a devastating loss for the city, and an uncomfortable precedent.

Re: “To meet green energy goals, Colorado will have to solve the data center problem

Don't forget about the noise from the cooling fans. That's a problem CS is facing now with the Bit Coin mining operation in the city, yet another form of pollution.
Solar panels on the roof MAY mitigate SOME of the daytime power usage but not all. And when the sun goes down... Acres of batteries, and THOSE pollution and disposal problems. Look at the batteries needed for the Australian grid - that will last all of five minutes should the wind stop blowing, Carbon credits? Just shuffling the deck...

Technology always outruns legislation and the morays of the citizenry.
