Transportation and logistics could've been handled differently. There was an article recently about pneumatic tube delivery of mail.

Trash collection, package delivery, etc could've been delivered more like water. Via pipes.

You wouldn't want to be in a situation where you empty bedpans by lugging excrement to the curb so that a sewage truck can pick it up. We thankfully have pipes for that.

We should expand the use of pipes. Imagine not needing to dispose of cardboard boxes all the time after receiving every package. It arrives in a canister, which returns itself.
Yeah, that's one unfortunate side effect.

Pretty slick website too.
Are there any systems that can actually capture close to 100% of sunlight falling on the roof and carry it somewhere else? All the systems you link are only for replacing illumination for humans. They don't provide anywhere near light flux sufficient for plants.
No. As I pointed out in another link, there were too many outages for transmission to cover it.

For example, California "only" has 10GW of north-south transmission capacity. TX lost nearly 45GW. Even if it was part of the East or West grid there wouldn't be the transmission capacity there to cover such a loss, plus the states closest to TX which were "connected" were also having major outages, which would have put even more strain on it.

TX does have HVDC interconnects to other states too, but I believe imports to TX were significantly down/zero over this crisis.
It's not just Texas. it's the entire south and sometimes more. In the NERC report from the 2014 polar vortex, it looks like 20-30GW were lost due to fuel shortages even in the north east.

> Failing that, you design in an procedural or workflow aspect that naturally avoids it. Failing that, you put in a system to force the use to confirm or review the action. Failing that, you train around it.

I view the procedural or workflow aspect as a subset of training. As an example, I always lower the gear and leave my hand on the gear selector until I see three green (gear safe) lights prior to selecting any flaps.

The operating handbook and factory checklists do not require this, but my planning and training has elected this optional workflow/procedure. Why? Because it's incredibly hard to get my airplane to slow down and come down for landing while completely clean (no flaps, no gear). If I use the factory accepted procedure to select approach flaps, I can get it slow enough to land. I've literally never seen a "pilot forgot the gear" airplane sitting on the runway with no flaps deployed.
The main point was that failure to digest something doesn't mean that you are allergic or intolerant. My impression was that this was what the example with babies' bodies "rejecting" some foods that they cannot process implied. Humans can eat stuff they cannot digest (fiber, corn kernels without chewing, anyone?) without adverse effects, stuff will just pass through. Unless you're eating nails or glass, but that's a mechanical damage...
Yeah, ideologically biased like the President of Exelon (quoted from December 2018):

“The cost of new nuclear is prohibitive for us to be investing in,” says Crane. Exelon considered building two new reactors in Texas in 2005, he says, when gas prices were $8/MMBtu and were projected to rise to $13/MMBtu. At that price, the project would have been viable with a CO2 tax of $25 per ton. “We’re sitting here trading 2019 gas at $2.90 per MMBtu,” he says; for new nuclear power to be competitive at that price, a CO2 tax “would be $300–$400.” Exelon currently is placing its bets instead on advances in energy storage and carbon sequestration technologies.

Your post in no way refutes my statement that "ERCOT cannot shutdown and reboot the grid".

Wow, I had never considered this! Although, as "UnFleshedOne" points out, that would imply a fixed geometry (not necessarily a grid) wouldn't it? We don't know that angles are limited within a "Planck volume," so they could be continuous (not that anything else seems to be!)

If this were true though, I'd think it would give us a fascinating tool!

The Texas state government made a systematic effort to avoid producers being subject to regulation that would have prevented this.

The regulations exist because it is possible to imagine an event like this. Large enterprises that many people depend on should be robust and reliable and not be subject to the kind of mistake a single individual might make.
> * Music scene is not good. I don't like to listen to country , rock ect.

You must not have tried very hard. Atlanta is a music hub. It's one of the best features of our city.

For one, we're the hip hop / rap epicenter. But we also cater to indie, alternative, electronic, and punk.

Pre-pandemic you could find shows every night at over three dozen different venues. Tabernacle, Buckhead Theatre, Center Stage, Masquerade, Terminal West, Variety Playhouse, The Loft, The Earl, Aisle 5, Chastain Park, Wonderroot, Smith's Old Bar, The Roxy...

I can't count how many times I was torn between seeing two or three different acts I wanted to see because they all happened on the same night. It's like a curse. That's how much music happens in Atlanta.

Music Midtown, Shaky Knees, Shaky Beats...

I think you forget that Atlanta is home to a burgeoning creative industry. And that's more than just music. In 2017, Georgia films collectively grossed more than films shot and produced anywhere else in the world. And we're still killing it.

Atlanta creatives and our art and culture scene are thriving.
It is a political issue. Texas refuses to regulate their grid to meet certain standards. They're so unwilling to do it that they purposely keep their grid separated from the rest of the country.

Now they have a grid that's collapsed and no way to import power from more reasonable areas.
Yes, consensus is the hard part. That was a massive research effort, with a lot of game theory and recently-invented cryptography.

Once you have that, you can get consensus on literally any data just by putting a hash of that data in each beacon chain block. In this case, a hash of the EVM state, while the EVM runs as before.

There's still some discussion on the design, but that's more about deciding the best of multiple options, rather than figuring out how to do it at all. As I mentioned in another comment, someone built a running proof-of-concept in about a day.

Exactly. I always thought of myself as responsible and healthy (and I basically was). I never overused alcohol, never binge-drank etc. I absolutely had no understanding how people could not regulate drug use because I had no problem with it.

A few years ago I had a lot of stress and started drinking to help me sleep. After only a few months I felt kind of agitated without a nightcap. I immediately stopped and now I just don't drink when I'm stressed.

So maybe in one sense I was right about being responsible, but on the other hand it could have very easily become a habit and now I understand how people slowly slide into addiction. It's arrogant to assume anyone knows how they'll respond to a drug as habit forming as heroin.
> The ones borrowing to get by are paying more money than what they borrowed to people who already had money to lend out.

If you are in the Western hemisphere, the interest rates are low (or negative) and the outlook of inflation is bleak. So it's more like the other way around.
In the US, we use more energy cooking food than we do growing it. Agriculture is only about 1% of total energy demand.

I enjoyed this piece as a controversial thought experiment, the "what do you believe that others don't" is strong with this one.

I was struck by the point where he talked about how heroin had made him a better person. The description he gives sounds like meditation and mindfulness would be a better prescription/solution than heroin.
They didn't get to pick and choose the winners. As volatility of the stock rose, clearinghouse collateral requirements increased. They didn't ask for collateral requirements to increase. Coming up with billions of dollars on short notice isn't easy for most companies (although they did, it just took a few days). There wasn't any choice but to stop trading if they wanted to remain in good standing.

This is the exact kind of shallow level of analysis that masquerades as meaningful insight and is especially susceptible to being turned into hyperbolic headlines and memes that ultimately become misinformation for the public. This is the exact same way the stock price became overinflated in the first place.
Nuclear's cost is almost entirely in the infrastructure, and it's paid over a very long time period. The business plan for nuclear is to spend a decade or two paying back your loans, after which you make big $$$ because the plant costs relatively little to run.

The ideal plan for nuclear is to pump out power at 100% 24/7. You save nothing by being idle, and you want to pay off your loan as soon as possible.

All that goes to hell once cheap renewables show up, because the moment wind or solar can sell power cheaper, a rational person would buy it from renewables. Which means that if the sun is shining, you're either not selling at all, or selling much less or cheaper than you'd like to. And so your loans now get repaid much later.

At some point a bank looks at that and figures that the proposition of maybe making a profit 30 years in the future isn't that great of a deal. That's a long time, for all the bank knows, solar might be dirt cheap by then and kill nuclear for good before it gets to making a profit. Probably better to put billions to some safer use.

Politically it's not a lot better -- nuclear costs $$$, and takes a long time to build, which means that if you're the one who got the country into nuclear on a large scale you can't really expect to see a benefit within your term. Worst case it goes wrong and is an expensive boondoggle, which doesn't bode well for reelection.

Nuclear may make sense if you think "emissions are paramount, screw money". But there's not a lot of people who'd be willing or even able to risk billions in such a manner.

The head line of the article does not seem to match its contents.

The article spends 90% of the time describing problems in the Texas grid.

The only mention of the nation problem is this throw away line at the end:

> The issue of extreme cold weather and electrical outages is a national issue that needs to be addressed. However, after repeated failings it hasn’t really been addressed.

Now that statement would make sense if 'extreme cold weather' had caused problems in other parts of the USA.

But to date I only know of two such events and both occurred in Texas.

To make matters worse the national energy regulator warned Texas this would most likely happen again:

https://www.bloomberg.com/news/articles/2021-02-17/texas-was...

That suggest to me the national regulator has these extreme weather events covered.

I've been there too, always used Steam to install the majority of the games I played. Then EA decided to only release Battlefield on Origin, then Ubisoft decided you also needed to install their launcher, now we also have the Epic Games launcher and the Blizzard Launcher (warranted they always had this).

Between each of these launchers they have their own chat platforms, I need to duplicate my friends list between them all and they each have their pros and cons.

It's not great and its frustrating. Clearly Steam had a fantastic solution and was ahead of its time in terms of digital distribution of content.

Why can't we move to a solution like brick and mortar stores where every game is made available at every online store? Then I can choose where I want to download the game from.
Which is fine. Given the massive community support for ETH2, the legacy chain is likely to have even less impact than ETC.
If you read the report from FERC of the 2011 issues in Texas, I'm amazed anyone can see this as anything but a political issue.

The setup of the energy market in Texas makes it pretty much impossible for providers to adequately weatherize their equipment. The only way for this to happen is for government to mandate adequate preparation for this kind of event.

And while this kind of event is obviously rare, it is only "once in a lifetime" for the very shortest of lives. The 2011 FERC report called it a "once in every 10 years" event, which is uncannily accurate.
> I've wondered about how much of outsiders' responses have been driven by their own prejudice against Texas and our current political representatives.

Californian with family in the Midwest - lots of folks are too dense to realize there are people on the other side of natural disasters when these horrible situations are happening. That prejudice happens to some degree, I've lived it =/

Regardless of politics, best of luck to you and your own.
The article's numbers are that 1m^2 of wheat needed 20m^2 of solar panels.

That implies a 5% efficiency in the "total solar captured area" of the solar panel + LED lights compared to just sticking the plats out in the sun, which is totally independent of the plants own efficiency in photosynthesis.

(I guess coming from a site about Low Tech, their slant on the numbers might be questioned, but they certainly hold up to initial scrutiny from here...)
I don't think you understand how government works, how they buy things, what data archiving/security requirements they have and, well, frankly, the value of paper as an archival medium.

About thirty years ago I worked on a sizeable archival project. Technology deemed "modern" at the time was very hard to justify. Why? Because nobody could truthfully answer a simple question: What happens when the hardware/readers go obsolete?

Well, the first thing that happens is that you have to migrate ALL of your data from the old medium to a new medium before the old one goes out of style.

That's all the bean counters had to hear to know they'd rather keep things on film. Film, as the argument went, is good for a long time if stored properly and all you have to do is shine a light through it.

The started a slow transition to digital some 20 to 25 years after that conversation. Guess what? They were right. The film was --and still is-- in pristine condition.
Reminds me of the Great Ice Storm of 98.

The North American Ice Storm of 1998 (also known as Great Ice Storm of 1998) was a massive combination of five smaller successive ice storms in January 1998 that struck a relatively narrow swath of land from eastern Ontario to southern Quebec, New Brunswick and Nova Scotia in Canada, and bordering areas from northern New York to central Maine in the United States. It caused massive damage to trees and electrical infrastructure all over the area, leading to widespread long-term power outages. Millions were left in the dark for periods varying from days to several weeks, and in some instances, months. It led to 34 fatalities, a shutdown of activities in large cities like Montreal and Ottawa, and an unprecedented effort in reconstruction of the power grid. The ice storm led to the largest deployment of Canadian military personnel since the Korean War, with over 16,000 Canadian Forces personnel deployed, 12,000 in Quebec and 4,000 in Ontario at the height of the crisis

Does all mining apply here? I saw some videos where people were setting up solar panels and minig using that power. If you have a system of solar panels + mining cards, is there more harm compared to no such system (not taking producing solar panels and cards into account).

No worries, though I actually have no idea what you're referring to. The only part of your comment that I can remember replying to was that single quote from you (which is still there). The subsequent edits in my comment were just adding links & expanding on them and trying to summarize their relevant points succinctly. It must've been a misunderstanding since that wasn't the intention of anything I wrote.

> With regards to the governor, Texas is a little different. The Governor serves year around, according to their term but mostly applies policy and sticks within the budget that the Legislature (only serves every other year) sets. In past terms, the Legislature have expanded renewables quite successfully (as noted above) and I hope that trend will continue.

Great, I hope so too. Again, this means some of the vocal ones have limited control. I don't know the power (ha) vs. size of each faction, but I'm not under the impression this is happening without a fight: https://www.houstonchronicle.com/business/energy/article/Tex...

Ok so aside from well known out of control things like another process telling the vm to brutal_kill you, cosmic arrays, or miscodes, OS interactions, oom errors or nif panics (the last three which bring down the whole VM anyways, so who cares), the crashing surface error for a BEAM process is extremely well defined.

The only no_returns otherwise are loops and hibernates. Hibernates are explicit. You might have a hard time analyzing the tail-calls to figure out an ultimate type that captures a no_return loop, but I think ignoring that condition would not be horrible for a BEAM type system (along the same lines as the random number crash scenario that I described).
Indeed, wholeheartedly agree. Short term gains is such an attractive proposition though...

>"So 1.5 GW of solar = 1.0 GW of nuclear."

That's not how it works. PV capacity factor is 11-12% to the 90-95% of nuclear meaning you need to install about an order of magnitude more PV effect not 1.5x.
