It would not exclude clear differentiation, however. :)

Just like a chatbot posting on social media can add a message footer “this content was posted by a robot” to a fluent and human-like message, a humanoid robot, while having human form, can clearly identify itself as a robot.

Personally, I think such a design requirement is higly reasonable on social media (as a barrier or action threshold against automated mass manipulation) but probably also in real life, if a day comes when human-like robots are abundant.

Very very impressive. :)

Now it’s also loading for me. Thanks for trying. :)

Strange, I can’t get the link to open. If I just click the link, (Firefox on Linux) it says “SSL_ERROR_INTERNAL_ERROR_ALERT”. However, when I revert to http:// instead of https://, it loads a page saying:

Can anyone else tell - does it open for you?

Why the water isn’t killing the fire?

Could be anything from sodium to calcium carbide to fluorine. :) Sodium makes hydrogen with water, carbide makes acetylene with water, and flouride just oxidizes water by grabbing hydrogen away from oxygen.

If the character’s plan is to try fascism next, I think they’re into fairly agressive substances. :P

That was a long story, and I was a fool.

I bought a car that had driven an incredibly short mileage, hoping to restore the battery to working order. Being unfamiliar with it, I was unable to find the fault at first, so I bought a second-hand battery separately to test the car. I found the problem, fixed the car, but now had a batttery with a few dead cells left over. After fruitless attempts to find another person in need of many cells, I decided to use them for my house. :)

Do y’all have any ideas/suggestions on how to do this or work on it (slowly)?

I have no idea. I can only say that the first time something happens, involves considerable risk of people being clueless about whatever they are getting into. :)

In aviation, the first will often enough crash and burn, and pilots are lucky if they get back home alive. :)

While the article takes no solid position about the benefits and harms of alleviating global warming with solar geoengineering, it does correctly point out that discussion and governance of the subject is lacking.

Some hypothetical examples:

Case A:

• a coastal country experiences increased storm surges, a large percentage of its population stands at risk, it perceives climate change as an existential risk
• this country decides to engage in solar geoengieering to cool the planet, however its neigbours on higher ground don’t perceive a risk from warming, instead they fear that wind patterns could change and deprive them of rainfall
• they accuse each other of violating each other’s rights, start a trade dispute and eventually make war

Case B:

• lots of people are convinced that efforts to control climate change by reducing carbon output have failed
• they decide to go for solar geoengineering, but the predicted impact on food production is -10%
• this affects the poorest of people most adversely, but there is no compensation mechanism
• cooling the planet succeeds, but results in outbreaks of famine

Case C:

• lots of people are convinced that efforts to reduce emissions have failed
• solar geoengineering allows to cool the planet to pre-industrial levels
• does incentive to reduce emissions disappear now?
• if the cooling effect is terminated, extremely fast warming may now happen

Myself, I perceive this as a last resort. If reasonable measures don’t save the day, this is one of the less reasonable measures that could buy time. I would like people to research this, so that capability would exist. But I would not be easily convinced of the necessity of taking action, as long as alternatives remain.

Summary:

• lies come out when mouth opens
• mentally unstable
• past of criminal behaviour
• incapable of seeking or adhering to expert advise
• needs adult help in diplomacy

I keep wondering why he seems to have any chance at all. Guesses:

• he seems to have access to considerable campaign money, due to oligarchs funding him (broken campaign finance laws)
• he has taken hostage the right-leaning electorate since they have no alternatives (majoritarian electoral system forcing a two-party landscape)
• some saw the exchange value of their labour disappear (and foolishly think the extreme right might help)
• some saw life change, can’t adapt (and foolishly think that reactionary politics would help them)
• some have graduated without any skill of political thought, because nobody taught them
• some live in social media bubbles

Obviously, society is not well. A healthy society should be able to recognize a confidence artist trying to con them.

Back to farming kale, then. :)

So it’s mainly asthma that people develop due to exposure to nitrogen oxide - and treating all the patients puts a considerable burden on society.

Unrelatedly, as a side note, I got curious about Portuguese cooking - for some reason the graphs show that cooking food in Portugal requires a three times higher percentage (30% as opposed to 10%) of overall energy consumption, implying either lower energy use for everything else, or higher energy use for cooking.

I wonder if there’s some secret sauce that is only made in Portugal and which is extremely energy-intensive? Or just a case of broken statistics…

I mean sure, if you’re at such extreme latitudes that you have months of total darkness, then solar will have a problem there. Maybe small modular reactors make sense for those niche applications.

Currently, solar still makes economic sense, but from April to October. Lots of it was built rather fast, now the adoption is slowing since the grid can’t accept it everywhere.

Consequently, summer is when oil shale miners rest and prepare for the next season.

Since the goal is to get rid of mining oil shale, big plans exist to install a lot of wind power. Sadly, this has gone embarrassingly slow, and it cannot cover winter consumption, and there is not enough storage.

As a result, some companies and building out storage, but only enough to last a few hours.

…and in the next country southwards, there is a huge gas reservoir that could accept methane, enough to last the whole winter, but nobody has a good enough handle on methanation to renewably produce a considerable quantity and store it there. :o

With regard to reactors, it seems likely that getting one would take 10 years and the local country here doesn’t even have legislation built out for nuclear power. They’re drafting it. Starting from zero is quite slow.

That’s a pretty big gap to cover with spamming more panels. I would venture to guess: this approach would work up to latitude 45 or so.

Where I live, in midwinter, the day is 6 hours long. Over here, wind turns more heads than solar. But yes, solar is riduculously quick to install.

Machinery comes is varying width. I would guess a farmer needs to decide at some point - is the priority using a 10-meter wide tool, or is it OK to settle with a 6-meter tool, or even a smaller one.

Basing on that, they’ll decide what the clearance between rows of panels should be. From an energy installation viewpoint, the shadow of one row should not cover another row during normal operating conditions. Assuming sun at 30 degrees elevation (“September on latitude 60”), the shadow of a fence that’s 1.2 meters tall will be about 1.75 * 1.2 = 2.1 m long. So from an energy generation viewpoint, one can pack things more densely than makes sense for farming.

Since 2021, nearly 4 full years, the world has closed less than 1% of active coal power plants.

Closing will come later, when alternatives are widely available. What renewable energy does currently - at least here - is forcing those plants temporarily out of the market, especially during summer months and windy weather. The plants will exist and stay ready in case of need for well over a decade, maybe even two - but they will start up ever more rarely.

Technically, the deal is: we don’t have seasonal energy storage. Short term storage is being built - enough to stabilize the grid for a cold windless hour, then a day, then a week… that’s about as far as one can go with batteries and pumped hydro.

To really get the goods one has to add seasonal storage or on-demand nuclear generation. The bad news is that technologies for seasonal storage aren’t fully mature yet, while nuclear is expensive and slow to build. There’s electrolysis and methanation, there’s iron reduction, there are flow batteries of various sorts, there’s seasonal thermal storage already (a quarter step in the right direction)…

…but getting the mixture right takes time. Instead of looking at the number of closed plants, one should look at the sum of emissions. To remain hopeful, the sum should stop growing very soon.

Also, costing €623,000 over three years sounds rather expensive for just 100m

It’s hugely expensive, but I expect most of the cost to be in the wagon that lays panels down and picks them up - and could hopefully service a big stretch of railway (if it works). That kind of systems will cost a pretty big penny.

I doubt if this project will “fly”, however. A totally horizontal solar panel at ground level is a far cry from producing energy efficiently.

3. How does it look under snow? :)

It is my personal opinion that a crossing is better emphasized with light from above. Snow cannot cover light.

As for bumps… there are bumps that work right (harm the suspension at speeds above the limit), and then there are bumps that harm the suspension at any speed. Road builders over here cannot seem to get them consistently right.

Also relevant: “Always shoot the messenger first.” :)

If news unsettles a person, and there’s a cognitive dissonance upon processing their world model (“everything OK with climate”) and sensory input (“another big freaking hurricane”) then if the person isn’t a model of rational thought and already has a fad for conspiracies…

…one might find it easier to add another conspiracy theory to one’s collection, as opposed to harder steps like refreshing one’s model of how the world functions. :o

Guy seems to be a walking disaster.

No matter whether he intends what he says or not, that’s definitely not how a presidential candidate should behave. If one wants to govern a country (as opposed to running it into ground), at the minimum one should not be ridiculous.

Last time, I recall, it took him a fairly long weaseling to use the border guard a bit, here and there. I don’t think the US military is eager to do his bidding, or cheerful about being drawn into his campaign.

Over here, in a different country on a whole different continent, the previous (now retired) commander of the defense forces had a habit of providing fact corrections when politicians lied, spinned or bluffed about defense. For a reason which didn’t need a detective to figure out, only conservative populists ended up on his shit list. :)

One of the conservative populists took being corrected so personally that he got into a social media confrontation with the general right before elections. Politologists later estimated that it was not beneficial at all to the politician involved. :)

That’s quite understandable.

On related notes, my first disassembly of an EV battery pack was very slow and careful, and the surface, boots, gloves and tools really carefully considered. Of course, EV batteries have those safety jumpers which split the pack in two, but even the halves are dangerous enough to worry.
