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