­xkcd thread

“I mean, half of these are undefined. And your multiplication dots are too low; they look like decimal points.”

“Now that I’ve finally gotten an electric vehicle, I’m never going back to an acoustic one.”

IRL the question is “what do you do when the battery, which is up to half the cost of the entire vehicle, is worn out and won’t keep a charge properly any more?”

My understanding is that long before that happens, the rest of the car will be shot. Pretty much everything I’ve read on EV battery life is that they’ll outlive the car.

Yeah, that’s an argument from 2010 when EVs were still really new. EV batteries now last a long time and don’t cost 1/2 the price of a new car, but the detractors still haven’t gotten a new schtick.

Okay, I stand corrected. In my defense, at my age anytime in the 21st century feels like “recently”.

I still think there’s a market for these:

The same thing you do when the drive train in an ICE is worn and it won’t move any more: Replace it or scrap the vehicle. The reason I got an ICE in 2023 was because I had the choice of replacing the transmission for $4,000 in a vehicle I’d paid $3,400 for or buying an EV with 5,000 miles on the odo for $20,000.

The car that got scrapped was a 2001. :slightly_smiling_face:

Batteries that are no longer good enough for an EV can be re-purposed for home or grid storage use

And once they’re no good for that, they can be recycled. There are companies that recover the metals from batteries. However, most car batteries are still in their original cars because the market for EVs is still pretty new. There weren’t that many EVs manufactured 15 or 20 years ago. Those companies recycle batteries from cars that have been in accidents or from other uses (cell phones, laptops, etc.).

There is a company here in Gilbert that recycles lithium batteries (7 min video) from any source but specializes in EV batteries. They’re dropped whole into a shredder-dissolver and three streams emerge.

  • Plastic shards – probably next to worthless since it would be mixed.
  • Base metals – steel, copper, trace amounts of silver and gold.
  • Exotic metals – lithium, nickel, and cobalt.

They claim a 95% recovery.

“This replaces the previous solar activity watch, which was issued last month when the sun took off its sunglasses.”

“I see, a bad sun, rising”.

When we see it snarling, we’re doomed. Doo-oomed I say!

As anyone who has answered misguided electrical questions can tell you, the real dilemma is “my phone charger says it is draws 50mA so where do I plug it in now that my outlets are 500A?”

“In contrast to the deep booming sound associated with the cannon in pop culture depictions, recent studies show it actually made more of a ‘toot toot!’ noise.”

“As always, you are permitted to call one person for guidance, but that person must be a grandparent.”

Not necessarily your grandparent.

All I gotta say is “Better call Beck:grin:

I bet she’d win that competition hands down.
