Jacking Up a Car Is Dangerous. Here's Why Mechanics Are Doing So Anyway
I suppose jacking off a car is also dangerous.
Depends. Are you a dragon?
Wasnt there subreddits for that?
Not that I know of.
There is dragonsfuckingcars.
You wouldn't download a car... And if you did, you wouldn't jack off a car...
Eh. That's not really comparable to lithium-ion batteries. Lithium-ion batteries are similar to bombs in that they're highly dense stores of energy. If something goes wrong and that energy storage medium gets exposed to air, or there's a failure in a charging safety mechanism, that's a chemical fire at best, explosion at worse, but no matter what, it's extremely toxic.
Acetylene and oxygen is also explosive, but you’re still allowed to have it and use it. Battery acid is extremely corrosive and poisonous. Gasoline is extremely flammable. A garage is filled with dangers. If you can’t service a lithium-ion battery in a safe way, you shouldn’t do it, just like you shouldn’t service your brakes if you don’t know what you’re doing.
Lol. A single gallon of gasoline contains approximately 34khw of energy. An EV with ~300 miles of range, will have a battery with between 80 and 100 khw. Or the same potential energy as about 3 gallons of gas.
People are familiar with gas, so it seems safe. But every gas tank is a literal bomb, and that's just for a car. I have no idea how big the storage tanks at gas stations are, but I'm assuming there's enough explosive in there to level a couple hundred square feet if one of those goes.
Lead-acid batteries also present a risk of explosion.

That's why you attach jumper cables to the dead battery first.
The whole repair thing should made super easy if we want EVs to succeed.
But that will never happen because the EV manufacturers couldn't charge ridiculous amounts of money for proprietary batteries.
That why we need regulators. The market doesn't magically deal with "Tragedy of the Commons".
God forbid that they concentrate on the quality of the basic vehicle instead.
Yup.. If you can't compete add tariffs.
Make all cars rechargeable with a single charging port. And that port should be USB-C
like 50 USB-C cables tied together to output enough of a charge lol
The highest available now is 240 W, so with 50 in parallel you get 12 kW. Fast chargers go up to like 300 kW but at home 12 is good enough actually.
Can't wait for all power cables to just be USB-C. I dream for the day where I can charge my phone with the same plug my induction stove uses.
I've said it before, and I'll say it again allow.. cars with CATL or Nio battery swap cassettes into the US.. It is so dumb that there are different battery setups for every manufacturer .. In a Nio I can swap batteries for less than a pack of beer.. Why not do that instead of this current BS system where you have only one pack and once that is done it is $10k
I heard NIO has this technology already and are looking to standardise it.
Every EV has this already. What they don't have is a standard. Not shockingly, every EV manufacturer will argue why theirs should be the standard.
Honestly if the department of defense adopts any EVs for troop transport it should come with a forced standardization. Just hand wave it as being for national security and the fact a lot of countries will probably adopt the standard, that should do the trick.
This was posted to one of the communities I sub to a day ago: https://spectrum.ieee.org/flow-battery-2666672335
This would probably be the best option if it takes off.
Is it money?
Is it money? I bet it's money

Interesting.
First of all apparently ublock, no script, or some combination of my add-ons kept me from seeing the message and I'm able to view the entire article.
Even more interesting is this text at the end of the article-
This story was originally published by Grist, a nonprofit media organization covering climate, justice, and solutions.
So this source basically spun an article from Grist and put it behind their paywall.
Following the link from Scientific American, the first line of the Grist article is-
This story was co-published with WIRED.
It's clowns the whole way down, yaaaaar.
Because that's literally a mechanic's job.
Danger, Danger, High Voltage!
Although it annoys me that mechanics consider even 400V "high" voltage. HV is supposed to be 1,000V, minimum.
