They were possibly confusing nitrogen with carbon dioxide. CO2 will definitely lead to distress in high concentrations, and has been used in some slaughterhouses.

What's the charging efficiency?

Most electric cars only have 1 gear and it's always engaged. If you put the car in reverse, it uses the same gear, but the motor spins the other way.

Even in neutral the motor still spins when the wheels are turned, it just doesn't output any power to the wheels.

She looks very polite.

There is a difference between climate concern, where you desperately want to do anything to fix the climate problems, and climate anxiety, where you are so overwhelmed by the climate issues that it interferes with your ability to take any action.

I suspect this study is focusing only on the latter.

Most Russian people have committed no crime, and many do not support what their leader has done. We should not condem people for the country they were born in.

I have used Kagi for several weeks and can't go back. I can finally find things on the internet again and I don't want to lose that again.

If you don't mind paying to use a search engine, Kagi is actually pretty good. Not as good as Google was 20 years ago, but significantly better than any other search engine I can find today.

Interesting extension. I think I'll give it a try.

It is entirely open source, and the website does a very good job explaining what it does and why.

It depends on a lot of factors including the battery chemistry.

NMC (Lithium ion) batteries are common in high performance cars and older EVs. They should be kept between 20% and 80% charge for normal use. 60% is ideal for storage, but anywhere in that range will do.

LFP (Lithium ion) batteries are common in cheaper and newer EVs. They don't have a problem with being stored at 100%, and do have issues with not being regularly charged to 100% (monitoring gets less accurate over time until fully charged again), so leaving it at 100% is fine.

Lead acid (particularly calcium) batteries get damaged when discharged too much, so it's fairly important to keep them topped up. If you are leaving the car for a long time, it could be worthwhile to connect a trickle charger to the 12V battery to prevent the car's computer from gradually draining the battery. Some cars will top up the 12V battery from the high voltage battery if left for a while, so this may not be needed.

While I have little experience with low temperatures, I suspect that the car will be fine if left as stated above. The battery shouldn't get damaged by low temperature storage, and shouldn't lose much charge over time. Just don't expect full performance immediately after returning to it.

Be aware that an underpowered or stuck stepper motor can "skip", causing the position data to be incorrect.

A servo motor has active feedback, so doesn't have this issue. Servos do have their own drawbacks too, so they are not always a suitable replacement.

It's likely been hacked by someone who guessed the default login details (when was the last time you changed the password on your washing machine), and is being used for malicious purposes such as DDoS attacks.

I find your lack of comma disturbing.

Prey gives you the choices up front, tells you they don't matter, then gives you a really good game to play.

::: spoiler plot twist The way you play is entirely up to you, but that's the point. Are you who you say you are? It's easy to say whether you'll flip a switch or push a person when you're answering questions at a desk, but it's suddenly much harder when you're actually faced with the problem. What will you choose? :::

Start today. Download VirtualBox (or equivalent software) and if you make a mistake, you can just nuke the OS and start over without risk.

You can always try Linux risk free in a virtual machine like VirtualBox.

If you like what you see, and you have any valuable data backed-up, you can try dual booting. That way you get to use Linux as your primary operating system, but can switch back and forth as much as needed.

I found I was dual booting Windows and Linux for over 3 years before I was comfortable enough to stop using Windows entirely. Switching to Linux doesn't have to be an all-or-nothing approach. You can take it as slow as you want.

The surgeons handle this regularly, it's routine for them. You get to relax and let them manage everything.

I went through lung surgery a few years ago and coped by deciding that I could trust the surgeons (and other medical professionals) completely. They know what they are doing, and they have procedures in place to make sure everything goes well.

Learning to consciously relax and trust everyone around you is a something that takes constant effort, but in my opinion, it's worth it.

My surgery went well, no complications, and my recovery was exactly on schedule.

An SUV is very different from a compact car. Small cars tend to have better visibility and maneuverability, and are just easier to drive. If it's with your budget, an electric car is also easier to drive (and cheaper overall) because you don't have to worry about gears.

The first few lessons will be overwhelming, particularly with stickshift. As you practice, you'll start doing more things without thinking, like when you put your foot down while stopping on a bike. I bet you haven't thought about that for a few years.

Just take it slow, and trust that the instructor will not push you beyond your limits. After a few months/years you'll wonder why you thought driving was even difficult.

If it were a reasonable option, I'd pick the train every time.

If you are worried, a qualified medical practitioner is always more reliable than a web forum.

Insufficient or poor quality sleep can cause problems with attention and memory, and can exacerbate existing conditions.

Poor sleep could be caused by a medical condition (sleep apnoea), or psychological (stress). Often stress can be hard to identify, particularly if it's long term stress.

Again, this might not be your problem, and finding the right doctor who actually listens to you is important. Don't be afraid to try more than 1 doctor if the first makes you uncomfortable.

South Australia has a huge amount of solar and wind, but relativity little storage, and basically no renewable base load (hydro, geothermal, nuclear). While the average renewable energy usage is fairly high, the instantaneous renewable usage can drop to almost 0 some days.

Solutions are being implemented, and the renewable mix is gradually improving.

It's so much worse than you could image.

Is this causal? The article seems to indicate that it is.

Is seems likely to me that people ill enough to be unable to brush their teeth would be more likely to catch pneumonia.

It hasn't happened to me, but passengers have been severely injured before.

An example of a minor incident.

Listen to the safety briefing. They wouldn't bother telling you if it wasn't important.

Keep your seatbelt on for the entire flight. The pilots can't always predict turbulence, and hitting the ceiling hurts.

Lithium batteries scale power and capacity at the same time. Flow batteries can scale power and capacity independently.

The advantage of flow batteries is that they can have enormous capacities without the added cost of upgrading the power, making it ideal for grid scale storage.

Even if this new flow battery reaches the energy density of a lithium battery, and can output sufficient power, it would still need to reach price parity to be competitive.

Adequate for cargo flights, not happening any time soon for passenger flights. Aviation safety is very strict and slow to change.

Flow batteries are great for long duration storage, but not good for high power delivery.

This means they will work far better as grid storage than as EV batteries.

Do you have a source for this? I'd love to look into it further.

I have a prototype self driving system in my car. It drives logically and consistently, but it doesn't behave like a human.

This would be a really helpful feature as self driving becomes more common.

Linux Mint Debian Edition (LMDE) and Lightweight X11 Desktop Environment (LXDE) are entirely separate products.

He doesn't burn very well.

I can be overstimulated and understimulated at the same time.

Don't tell anyone, but I actually only used 1 significant figure, so anything above 50% will do.

I'm also using the version of significant figures where I work backwards from the answer, otherwise I'd need 95% or higher and that's too difficult.

I have a spherical frictionless house in a vacuum.

Most engines are less than 30% efficient at producing movement. The majority of the energy is lost as heat.

Thermodynamics tells us that pretty much all energy ends up as heat. In a closed system, any device that uses energy is 100% efficient at making heat. A 1000W computer will make exactly as much heat as a 1000W heater.

A 100% efficient engine can only exist if the desired output is heat, thus making it a pretty useless engine. Also, in a closed system, the exhaust cannot leave.
