Kudos for a measured response to my sometimes snarky tone.
I only had the time to read the executive summary of this thing, but I learned a bit more about nuclear power plants.
It’s still not enough for me to evaluate how well that can integrate with a grid dominated by renewables (can the load following be fast enough, to match wind and solar fluctuations) but still good to know more.
That’s a super basic view on the science of nuclear power. As an engineer, I need a lot more than that, because it needs a lot more to put basic principles into working projects.
So, is there a nuclear powerplant, that exists outside of some powerpoint slides, that is actually used to match fluctuating generation from other energy sources and/or fluctuating demands?
All of the ones I know are/were used to provide a base supply by running more or less 24/7 at their designated output, not least because they need to do that to be even somehow economically feasible.
Where’s an example for an operating nuclear power-plant that can be dialed down to match demand?
Afaik they have lots of momentum (for days even), and even their propenents argue for them being critical for providing a base supply1. Never have I heard anyone claiming they’d be good for matching fluctuating demand. Can you back that up?
Or are you getting your anti-reneweblaes lobbying talking points mixed up? That argument is usually used for natural gas plants.
1 which doesn’t make sense in a renewables dominated grid.
Nuclear isn’t exactly ‘burning fuel’, at least not in a traditional sense. But I guess you just mean that as ‘consuming a finite, non-renewable ressource’ which it still does.
No disagreement, I’m just here to nitpick that bit of phrasing.
Yeah, though I’ve never visited, I’m aware that US traffic is in large parts a hellscape for anything that isn’t a car or motorcycle.
So very different circumstances. Arguably, the solution would be a shifting paradigm in urban planning, rather than fast E-bikes. But the latter is obviously much easier to achieve.
Die Analyse müsste aber dann doch lauten: Reallöhne steigen wieder, hinken aber langfristig immer noch der notwendigen Steigerung hinterher.
Es ist allgemein etwas begrenzend, nur einzelne Zahlen herauszupicken. Ein Diagramm über einen längeren Zeitraum ist viel aussagkräftiger.
Du gehst das falsch an. Meine Erwartungen werden hier regelmäßig erfüllt. Hab allerdings nichts gutes erwartet.
Ah, an important fact I forgot to mention this rule applies to bikes with pedalling assistance, so pedelecs, strictly speaking. Real E-bikes, that can use their motor by flicking a switch always require a license plate. That’s the silly part of the law her, imho. I just added this fact after having written the rest.
If you’re doing more than 15 mph as a long-term cruising speed and 30 mph burst, I have to assume, you’re a fairly fit and healthy person. And of course it wouldn’t feel unsafe for you to do the same speeds with an E-bike. But what you have to consider is, that these bikes are also very popular with people who are not fit enough to reach those speeds unassisted and maybe haven’t even ridden a bike for a long time. When I see some of our elderly citizens using them, I’m pretty happy they aren’t allowed to go that much faster, since they are also not restricted to use roads and often share the way with pedestrians.
What you also have to put into consideration is, that this limit doesn’t mean, that you cannot go faster, it’s just that the assistance shuts of at ~15 mph and everything on top, you have to pedal in yourself. Which is a bit more exhausting, due to the overall heavier bike, but something I regularly do, even though I ride a pretty shoddy 10 year-old bike with less than ideal mechanics.
The overall experience of riding a bike like that is pretty damn great still and not at all as terrible, as you make it sound. You can go your regular cruising speed on flat parts, no restriction for downhill, but you get an extra lift for uphill sections, and what’s the biggest plus for me is the extra acceleration - and ease thereof - when you have to stop at cross-sections and traffic-lights.
It’s all depended on the surrounding traffic and environment a bit, so I’m not saying a carbon copy of that rule would be ideal for the US for example. But even though I’d wish for 3 mph more, it works pretty well around here. And don’t forget that you can simply get a bike with a license plate for anythig beyond those rules.
Just as an inspiration: in Germany the cut-off is 25 km/h (I’ll leave doing the math to you). I think that’s almost reasonable. Personally I’d favor 30 km/h, because that’s a common speed limit for residential areas over here and that would allow them to better flow with traffic.
Drop an m and this still holds up.
Do you mean all that squishy cuddly soft power you guys employed, when you invaded Iraq? Or Afghanistan? Or Iraq again?
I have no idea about skateboard prices, like at all. But maybe a new board is cheaper than their fee was. You can repurpoe the wheels after all, which I imagine to be the expensive bits.
There have been a couple interactions in my life where I’ve had to remind people that cornfields, livestock pastures, and even former farmland left to go wild for a few years aren’t nature. They are distinctly and irreversibly human-centric areas, with human-dictated ecosystems and populations.
That’s true and all, and I have few good things to say about modern farmland. BUT the question arises, what is nature? Is it a sort of landscape that is devoid of human influence and is that necessarily better and the ideal to strife for? I don’t think so. In my opinion the human vs nature dichotomy, while a very common idea in many societies, is at the root of the problem. Humans are not distinct of nature, they are a part of it and we have to learn how to behave like that and use our landscape shaping abilities to let nature thrive and us humans in it.
For my part of the world at least, scientist say a hypothetical state of nature would be mostly beech forests, which is a pretty cool forest, if you’ve ever been to one, but it isn’t all that diverse. Cutting down large swaths of that forest and converting it into a type of farmland consisting of more diverse and smaller structures - different kinds of timberland, crop fields, meadows, pastures, orchards and vineyards, villages and hedges in between all of these - historically enabled an even more biodiverse environment, than that hypothetical state of nature.
Most of that diversity had only been lost, when agriculture transformed from a labour intensive small scale business into a mechanized and chemically fertilized industry, with much bigger structures and far fewer hedges in between. We can be thankful, that most of us don’t have to toil as farmers like in the agricultural societies of those days and a regional draught or a bad harvest isn’t as life threatening as it used to be. But at the same time, I hope that we will find ways to balance our agricultural production and use of the land in a more sustainable eco-friendly way. I kinda hope, that agricultural robotics may enable us to go back to smaller field sizes or even find completely new forms of agriculture, that a allow for a more structurally diverse landscape again, that is better suited for coexistence with other creatures.
Strictly speaking that’s not efficiency, but a coefficient of performance.
And funny enough the work energy doesn’t even have to be electricity. It’s actually mechanical energy, that is required and you could even power a heat pump with a steam or diesel engine.
Each buffalo in the second picture represents 75 bison. By that metric, the first picture almost comes close to representing the third number. But the third picture just doesn’t fit here, and the first number is so huge you’d need at least 2000 times picture one to represent it.
Wohnst du schon länger da? Wie alt bist du circa? Geschlecht ist evtl auch relevant.
Der Standardratschlag für Dorfleben ist halt in irgendwelche Vereine zu gehen (Kirche zähl ich mit dazu). Da knüpft man am ehesten Bekanntschaften. Kann aber als Metalhörender Atheist mit einigen Nerdinteressen und reflektiertem Trinkverhalten sehr sehr gut nachvollziehen, wieso man sich in der freiwilligen Feuerwehr oder dem örtlichen Fußballverein nicht wohl fühlt. Landleben ist in der Hinsicht wirklich Arsch.
Ich hab mal in Ulm gewohnt und es da aber geschafft eine Gruppe für Pen&Paper-Rollenspiele zu finden, die jedoch alle außer mir nicht in der Stadt gewohnt haben. Es gibt sie also, die Landnerds. Ich kann daher empfehlen in den einschlägigen Internetcommunities gezielt nach Leuten aus deiner Umgebung zu suchen. Außerdem braucht man ein wenig Kompromissbereitschaft. Viele Nerdhobbies neigen dazu extrem nischig zu werden und zur Lagerbildung, aber man sollte sich wirklich fragen ob es einem beispielsweise so wichtig ist Warhammer Fantasy zu spielen wenn man mit Warhammer 40K einfach eher Mitspieler findet. (Ich hab btw keinen großen Plan von Warhammer, ist nur so ein aus der Luft gegriffenes Beispiel)
Or a weird generalization.
There are people who love to complain everywhere and in every age group, I’d say. But you don’t hear the ones who don’t complain complaining.
Perception is biased.
Anywhere, where you can get insects as food. There are dedicated online shops and the only other place I’ve ever found them IRL was a camping/outdoors supplier, they are a very light source of protein. That’s in the EU though, don’t know how insect food is regulated wherever you live.
I never bought it though, I found it pretty expensive, don’t really need it, and I’m a vegetarian anyways. I have tried them at a museum once, though. Pretty unspectacular if you ask me, a bit nutty in taste but also quite dry. I prefer actual nuts as a snack.
It still does.
“If you don’t have evidence, that the thing you’re claiming happened, it didn’t happen”, is what that phrase is saying. It doesn’t follow, that if you have a pic it definitely did happen.
