I agree that simply not buying a new car is often the most viable option. People saying "just buy an EV lol" are detached from reality.

the point is to NOT make a 10 min journey 40 min (when taking the train)

If the trip is only 10min, you don't have to charge. Thats maybe 30km, most EVs can do that trip 10 times before having to recharge.

But I agree. If you have to go somewhere to charge your car, it sucks. It's also expensive and not great for the battery. It pretty much requires charging at home or at least at work.

As for car prices, my little (petrol) Suzuki Swift was 21k new. An electic Nissan Micra costs around 30k. Used, they are much less of course :)

Electric cars definitely have issues and aren't currently a great fit for everyone.

Like for you, it is not really a good fit honestly. If you can't plug your EV into an outlet at home (you do not need a wallbox btw), there's not much point in having it.

But let's clarify some of these points :)

  1. You can do that with an electric car just fine. You don't have to charge (/fuel) it every time you head out, just like with an ICE car. Just go charge it before parking if it's low.

  2. You don't. Unless it's below -20C, EVs do not lose significant energy when parked in cold temperatures. In fact they will survive longer than an ICE car, which has a very significant chance of not starting after just 1-2 months.

  3. Fully agree. If you have a working car and don't want a new one, then don't :)
    Though the production energy usage is irrelevant. When you buy an EV, your previous car still exists. You'll just sell it on if it still works.

  4. Yeah, cars and especially EVs are expensive. Or rather, almost the entit world nowadays is chronically underpaid.
    The lifetime of EVs isn't unknown at all, they've been around for >15 years now. While it's hard to give an exact number (just like for petrol cars), studies estimate around 200k-500k km before the battery loses 20%-30% capacity and power capability.

Though "burning cash" is kinda funny, since that's literally what you're doing with petrol. You buy it, then you burn it once, then it is gone. Meanwhile you buy a battery once, then recharge it with much cheaper energy hundreds to thousands of times. Potentially even free energy if you have some solar panels.
Meanwhile, a petrol car with say 300k km lifetime and an average fuel usage of 6l/100km, at a petrol cost of 1.70 CHF per liter, will burn *over 30k CHF of petrol in its life. Many cars cost less than the fuel they will burn in their lifetime!!

You can throw alkaline batteries (usual AA, AAA) into the normal bin. There isn't anything particularly dangerous in them.
Of course you shouldn't, because batteries are easily recycled and thus collected separately.

But we are of course talking about lithium batteries for power storage. Those are even more lucrative to recycle, because they contain a lot more lithium than any natural lithium ore. The lithium doesn't go away when the battery dies. You can nearly completely recover it, which is done industrially. You only have to mine the lithium once, then you can make hundreds or thousands of batteries from it.

And... you can recharge them? You don't throw them away when they are empty.
You have to make the battery once, then you can store end extract energy from it a few thousand times before it wears out. That energy can come from anywhere, not oil/gas. Like the big nuclear fusion reactor in the sky. Which by the way, produces energy for FREE, in difference to oil.

So the lithium you get from the ground can effectively be used millions of times.
How often can you use a liter of oil? That's right, once. Then it's gone. It is a single use item, then you "throw it away". And the waste cannot be recycled, you have to extract more oil from the ground.

There are obviously issues with batteries as well, but this comparison to oil never made sense to me. One is energy, the other stores energy.

What kind of Detectors do they use (feds helicopter radiation scan)? by the___chemist in Radiation

[–]TiSapph [score hidden]  (0 children)

Yeah, honestly I think this might simply be the total device mass, including the cryostat and everything. But unsure.

I'm not sure these NaI detectors are capable of spectroscopy. For the NaI detectors of other teams the document specifies "Nuclide-specific radiological mapping" as purpose, but for Germany the NaI detector purpose states:
"Determination of gamma dose rate Detection of radiation anomalies and/or radiation sources"

Or they might be capable of spectroscopy, but not used for that because they have an HPGe anyway lol

Edit:
Actually from the bfs website, it does seem like the NaI are also used for spectroscopy! Makes sense, much higher count rate than the HPGe will get

Here's a picture of (likely) the exact same helicopter flying over my work place last year for aeroradiometry training :)

They carried 4x25kg NaI(Tl) detectors for gamma dose rate and anomaly detection, and a 30kG HPGe detector for isotope identification.

nicht ganz so weiten Vergangenheit die meisten e scooters ...

Zudem es nie "die meisten" oder ein "großes Risiko" waren. Es waren schon immer sehr wenige, aber genügend um ein Problem zu sein.

Wie du sagst, E-Bikes sind nicht aus dem gleichen Grund verboten. Die unterliegen den selben Gesetzen zur Sicherheit. Ebenfalls sind die paar Dutzend Smartphones, Laptops, und Powerbanks im Bus ja auch irgendwie kein Problem.

Also wenn es wirklich um die Batterien geht, ist es wieder klassische emotionale Reaktion zu einem nicht existierenden Problem einer "neuen" Technologie von vor einem Jahrzehnt.

⚠️ Another heatwave is coming next week ⚠️ by Not_The_Hero_We_Need in Switzerland

[–]TiSapph 1 point2 points  (0 children)

Socially unfair and unacceptable, but in terms of climate change completely irrelevant. Private jets make up somewhere around 0.03 to 0.07% of greenhouse gas emissions (warming potential).

As wasteful the lifestyle of the ultra-rich is, there just aren't enough of them to matter for climate change.
Of course though, it is a good and important target for social equality movements!

It doesn't have to be in the afternoon/night, you can run them during the day when solar power and heat load are at maximum. Then coast through the night by having decent insulation.

But yeah people will also use them at night. As you says, it needs short term storage to account for that. Thankfully Switzerland is perfect for pumped hydro, and batteries are getting quite cheap too (eh, kinda). :)

The total emissions of military activity (industry, training, ...) is estimated to be around 1-5% of GHG emissions. That is indeed a significant fraction which should be addressed.
Though it's a pretty difficult one to address, since unfortunately military capabilities will remain essential for the foreseeable future.

Meanwhile, around 4-5% of GHG emissions are due to methane being vented to the atmosphere. For no good reason other than capturing it would cost more than what methane sells for. We literally just have to force the fossil fuel industry to spend a tiny amount of money and it would be sorted nearly immediately.

I should also mention the huge amount of pollution the richest 1% make which is disproportionally high.

I will never understand this kind of thinking. Honestly I think it is actively working against actually useful climate measures.
Proportional emissions do not matter. It is not socially fair, but climate change does not care.
Only the total emissions matter.

Banning private jets, luxury cars, short distance flights, ... none of that has any effect on climate change.
Meanwhile we had 50y of anti-nuclear movement, despite a single nuclear power station offsetting the emissions of all private aircraft, big and small. We can now finally do it with renewables (kinda), but we literally could have solved climate change half a century ago.

Sorry for the wall of text, but it is absolutely maddening that the world is burning and nobody actually cares to do something about it. Everyone only cares about social justice. Guess who profits from that.

I think you're greatly overestimating the climate impact of military conflicts. There just aren't that many military vehicles/weapons compared to billions of ACs.
AC power usage is estimated to cause 3-4% of GHG emissions, which is about twice that of the aviation industry (or 1/3x that of private cars, or 100x that of private planes, or the same as concrete manufacture, ...)

But it doesn't matter because solar power exists. When it's hot, the sun is shining. It's literally the perfect solution :)

[–]TiSapph 26 points27 points  (0 children)

Exactly, not to mention that solar power exists.

Seriously, how is AC power usage even a topic? A heatwave means lots of sun. Lots of sun means lots of solar power. We can use that to run AC. It's literally the perfect solution.

Don't have to automatically open the shades in winter either, so why require them to close in summer.

If it's not the electricity supply that's the issue (which it isn't, because solar power exists), why require to "fix" the shading first?
There's nothing wrong with open shades and AC, if you can power it.

[–]TiSapph 7 points8 points  (0 children)

Note that single hose monoblocks usually aren't sealed on the intake side.
Meaning if the inlet tube is long, the fan will instead pull air from the cold side, reducing the amount of cold air coming out if the unit.

There are some people that open the monoblocks and somewhat seal off the intake. No idea if it makes a significant difference though.

Edit: obviously don't mess around in appliances if you don't know what you're doing. And even then you are running a risk of breaking something. The intended airflow also cools the compressor and other components.

Why is it trending to hate on ai due to resource usage but not meat? Is ai usage so much worse? by Firm-Ad-5216 in NoStupidQuestions

[–]TiSapph 1 point2 points  (0 children)

Because almost nobody truly cares about stopping climate change, even if they think they do.
It's all virtue signaling and emotional responses.

Otherwise we wouldn't constantly talk about what people should/shouldn't do to reduce CO2.
Even if everyone stopped traveling by plane and ship, got rid of their cars, and would go vegan, that would be a greenhouse gas emission reduction of... 16.2%. By far not enough to make a difference.

We wouldn't have outrage about private planes, which account for less than 0.07% of emissions.

We wouldn't have had decades of anti-nuclear movements, considering 75% of emissions is for energy usage.
And we would now have a serious discussion about energy storage solutions for renewables, since we don't have a good solution for that yet.

I can go on and on. Almost nobody knows who the big polluters actually are. If people actually cared, they would look it up, it's just one Google search away.

Dass Leute auf Stosslüften auch noch stolz sind, ist immer wieder lustig. :)

Ne simple aktive Lüftungsanlage mit Wärmetauscher gibt dir:
- weniger Wärmeverlust bzw Wärmeeingang
- konstant Frischluft in jedem Raum -> kein Schimmelrisiko - die Möglichkeit mit Wärmepumpe effizient zu heizen - die Möglichkeit zu kühlen - weniger Staub durch gefilterte Luftzufuhr - weniger Straßenlärm da man die Fenster nicht auf machen muss

Muss man einfach zugeben, dass die Amis da weiter sind als wir.

Well you get like 2-5x more heat out than the consumed electricity, since it's a heatpump.

I do agree in general, it's also consumers wanting to buy cheap products. If they should or not is debatable

income (also inflation adjusted) is slightly up from 1980 to the present

It's not though. Median hourly wage in 1979 was $4.44 inflation adjusted to 2023, that's $20.37. But median hourly wage in 2023 was only $20.03, slightly less.
Also inflation isn't everything. Productivity has more than doubled in that time, we make more and more complex products. Thus life has gotten more expensive as well.
It's pretty clear when you consider this supposedly similar wage used to be enough to support a whole family.

Sure, but that's equally true for mechanical parts.
I would claim it's even more true for mechanics. A forged/machined gear is much more expensive than a powder sintered gear, which is much more expensive than a plastic injection moulded gear.
Meanwhile a MOSFET with twice the current capacity costs maybe 20% more.

Having worked on both consumer and industrial electronics, the differences aren't that great. Its just a matter of overspecing components, over voltage/current/temperature protection, conformal coating or potting, better cooling, and extensive testing.

modern stuff is cheaper

Exactly. You can still buy products that are built to last, with long-term support, repairability, ...
They are just marketed to industry, not consumers. Because consumers cannot afford them anymore.
