So we can have autonomous metros, buses and taxis that allow people anywhere when they need it so they don’t rely on having a car?

I live 2000km from Chernobyl

Chernobyl is not comparable to a nuclear bomb. Chernobyl is a reactor, made to release a steadily amount of radiations for years to make electricity.

Chernobyl irradiated a large area because the graphite that was located in the reactor core has burned, and the fumes have been carried by the wind, taking a lot of high-level activity nuclear waste hundred or thousands of kilometers away.

A bomb is way smaller than a reactor, and is designed to release most of its energy instantly to make the biggest explosion possible. That means a short burst of radioactivity very high level of radioactivity, with a very small half-life.

A few days after a bomb explodes, most of the radiations would have depleted.

Anyone who has a different opinion than mine is necessarily an idiot

Storing so many videos has a financial and ecological cost. When you reach thousands of hours of videos, it’s time to ask yourself if it’s really useful to keep them all.

I liked the thought that if I were to lose my phone while traveling, I could just borrow a computer and access all my accounts anyway and not getting very uncomfortably stuck. This is putting me at big risk there.

It might help you with deciding how much storage you want

They don’t

That’s not brain drain. Brain drain is when high qualified people leave their country, mostly because of the lack of infrastructures costing them opportunities for studying or working in their respective field.

What you’re talking about is capital flight. This is an issue that is systematically raised as a counter-argument by liberals in debates on taxation. The problem is that it is seriously overestimated:

• Leaving a country is a lot more complicated than it sounds: you lose your family, your friends, your culture, your habits. Many millionaires who leave their country end up coming back after a few years.
• You can’t relocate your real estate investments.
• Going abroad doesn’t exempt you from paying taxes (especially exit taxes).
• A country that wishes to do so can prohibit the relocation of a profitable company, or even nationalize it.
• Many rich people who threaten to leave if taxes are raised end up doing the math: if there’s a profitable business, they’ll stay. And in a country that finances its infrastructure soundly and has a good distribution of wealth, there’s profitable business to be had.

While true, how is that any different to the arguments that were used for TV?

Television is bad because it is a passive activity, but it is less harmful than the continuous ingestion of micro-videos. But I don’t see what it has to do here.

Additionally, Lemmy is a social network in the same way that Reddit is. Is this not also dangerous?

What’s the connection? I didn’t mention Reddit.

As has been the recommendation for practically everything for the four decades I’ve been on this earth, moderation is key. Instead of hating new media, either regulate it (if the evidence is truly that great) or treat it with healthy moderation.

This would be to ignore the particularly addictive nature of this kind of content. It would be like comparing apples to Snickers: both are sweet, yes, but one is much more problematic.

Let’s be blunt here. Most of the people in this thread aren’t worried about health

That could be a point, but I’m pretty sure that if you ask anybody, the main reason given would be that it makes you stupid. But I can agree that this opinion would not necessarily be based on anything other than the eternal contempt for novelty as video games or manga were, for example, before they became popular.

ITT: People in their mid-twenties or later, who feel superior to those that like one form of media over their preferred media.

You’re just waving away an important fact, which is that shorts and their equivalents are notoriously known for killing attention spans and disrupting the management of dopamine in the brain, causing depression in particular.

We are no longer simply in the traditional custom of the elderly who despise the activities of the younger generations, we are talking about health.

Hexgears and of course lemmygrad.ml are of the same kind

• Those are tires, not wheels.
• 35% which uses them means that 65% don’t use them.
• You said “no matter gear you have”, so you can’t use that point.
• With 20cm of fresh snow, even a normal car would be stuck. But if you tell me that you use a special car (a pick-up for example), I will argue that you can use a special bike (such as a fat bike) and roll with it without problem.

And we could save a lot of people if they put on helmets to walk down stairs, and yet I don’t see anyone saying that people are stupid not to wear them.

And your friend, if he drives at 30mph, of course he has to wear a helmet, but the subject is not a sporty practice of cycling, but bike commuting. And helmets does not protect you from a shitty infrastructure and tank-like cars that run you over, so maybe it would be good to stop insulting people and bring some nuance to this debate.

Guess dutch people are stupid, but at least they have way less death per kilometer while cycling ¯\_(ツ)_/¯

interesting idea, though Chernobyl and Fukushima were both gen2s 💀

The reactor that exploded at Chernobyl was an RBMK model, not a PWR. This implies major design differences from French PWRs, including:

• A positive temperature coefficient, which means that an increase in core temperature leads to an increase in reactivity, which in turn leads to an increase in core temperature, and so on, implying instability and the possibility of a runaway. French PWRs are designed with a negative temperature coefficient, so an increase in core temperature leads to a decrease in reactivity, and vice-versa, physically preventing the runaway that caused Chernobyl.
• A flaw in the shutdown system: graphite rods were used to reduce reactivity during reactor shutdown. On the one hand, these graphite rods descended too slowly into the reactor core, and on the other, they physically increased the reactor’s reactivity when they were first inserted, before reducing it. In fact, it was irradiated graphite that burned and radioactively contaminated the whole area around Chernobyl, not uranium or anything else. On french ones, there is simply no graphite, nothing inflammable nor any rods of any sort, it’s water that’s used to stop the reactors.
• There was also no containment vessel.

Two things to note: the USSR knew about these defects years before the Chernobyl disaster, but the scientists who raised the alarm were neutralized. The other is that the explosion and fire in the reactor were caused by the failure of inexperienced technicians to follow procedures, under pressure from senior management, because the plant was to be visited by a high-ranking official the following day, and therefore the tests they were running at the moment had to be completed at all costs.

Chernobyl exploded because of the USSR’s cult of secrecy and appearance, causing incompetence and corruption.

For Fukushima, it should be noted that Fukushima Daini, although closer to the epicenter of the earthquake, but with better safety standards, was only slightly damaged and even served as a refuge for tsunami survivors.

For Daichii, same thing as Chernobyl, we have a very long list of failures and even falsifications by TEPCO dating from 2002, and even more in 2007, with alarms sounded on all sides by seismologists and scientists of all sides, and the government did not react.

We must understand that these are not disasters that happened out of nowhere, that we could never have predicted, and even less that we could never have avoided. It was a very long succession of bad choices by the incompetent and corrupt.

But despite all this, the Fukushima nuclear disaster caused no deaths, and Chernobyl only killed a few thousand people at most. Nuclear power, in its entire history, has killed only a fraction of what coal kills each year.

I guess it could be made more safe cheaply with modern electronics and software (seeing IoT/“AI”/boeing software engineers in a nuclear facility would freak me the fuck out though)

It has already been done, and without AI/IOT or anything of that kind. For the French REPs, this resulted in the implementation of additional testing protocols (I know that they tested accelerated aging over 10-20-30 years of parts like cables, for example), addition of generators, renovation and improvement of industrial parts, etc.

Both Chernobyl and Fukushima could’ve been avoided/reduced in effect with good failsafe software imo.

No. Fukushima Daichi’s walls were just not meant to handle more than a 5 meters wave. It took a 14 meters high wave right in the face.

I kinda doubt we’d be able to make gen2s cheaper than gen3s (at least in small capacities) though, because their production lines and designs would’ve been long shut down/forgotten

The industrial fabric has been crumbling for a long time, that’s for sure, but at least the designs are much simpler, and we have thousands of engineers working on gen IIs and can contribute their expertise. We don’t have any of that on the gen IIIs.

Pretty much every nuclear reactor that’s recently been built has been crazily over budget and significantly late. It seems it is usually a decade later than planned.

If you look at the EPRs, well, we can thank the Germans who co-developed the project, and pushed for excessive requirements making the design complex, such as the double containment and the system to make maintenance possible without shutting down the reactor. Requirements that the French didn’t need or want, but which were accepted as a concession to keep the Germans in the project, before they slammed the door anyway.

Even Okiluoto and Hinkley Point can be regarded as serial entries, so different are they from Flamanville, and so much work had to be done to simplify them.

Let’s scrap the EPR design, go back to Gen IIs for now, since we know they’re reliable, safe, cheap and easy to build, and move straight on to Gen IV when it’s ready.

Anyway, the beginning of construction is a highly misleading timeframe. There’s a long process before construction even starts. Not unique to nuclear reactors.

You still have nuclear power plants, you don’t even have to start from scratch. But yes, NIMBYS are a significant problem, but renewables are already facing this problem too, and it’s going to intensify greatly with the amount of space it takes to build wind turbines, solar panels, and the colossal amount of storage it takes to make them viable without fossil, hydro or nuclear power.

I dislike nuclear reactor discussions because of similar arguments. E.g. “new technology” fixes some problem, while ignoring the drawbacks

I’m talking about Gen II reactors like the 56 that make up France’s nuclear power fleet, which are tried and tested, safe, inexpensive, efficient, and have enabled France to decarbonize almost all its electricity in two decades. I’m not into technosolutionism, I’m into empiricism.

If someone says that it’ll take 15 years then the person didn’t solely mean the actual construction. They mean from wanting it to having it working.

Okay, so the 4 Blayais reactors, totalling 3.64GWe (equivalent to almost 11GW of wind power, but without the need for storage or redundancy) were connected to the grid 6.5 to 8.5 years after the first public survey, made before the project was started.

I’m not claiming that every reactor project will be built so quickly, but we have to stop pretending that nuclear power is inherently slow to build. It’s the lack of political will that makes nuclear power slow to build, and it’s not an unsolvable problem.

Gen II reactors are the reactors design which has been built between the 70’s up to 2000, it has nothing to do with SMRs.

My point was that there’s no reason to insist on a ridiculously complex reactor design such as the EPR (which is a Gen III reactor), and that we can simply go back to the proven designs of the second generation for two or three decades, until we finish developing the fourth generation, which has real arguments.

Building nuclear takes on average something like 15 years

Building EPRs, yes. Not Gen II reactors, which could be built and running only 4-5 years after the beginning of the construction.

Germany’s coal will be shut off by 2035 anyways.

Only to be replaced by gas, which is still far from being carbon free.

Besides, Germany already has a huge problem because no one can figure out where to put the nuclear waste they already have

No one can agree on where to put nuclear waste. This is not some unsolvable problem, it’s just anti-nuclear that opposes every solution given by scientists.
