Water. Best way to put out an EV fire is to keep dousing it with water until it cools down enough to not be on fire.
In case you’re not being sarcastic, Whistlindiesel…
But they’ve also been the target of some vandalism.
EVs tend to look like this after a battery fire, and the Cybertruck is easily the most hated vehicle ever made. I wouldn’t assume that this one caught itself on fire.
Specifically this one which I find especially haunting:
Like not only are we intelligent life, we look like this, and we look like this on the inside, and we have technology that can see ourselves on the inside. And we just thought you’d find that neat.
If it used the notification display to show your most recent calculation reault, that might be useful. I know some apps mis-use the notification counter for other things.

But who was phone?
It’s a lot of work. At the end of the day, I spent about $1k to get about $100 worth of gold, so it’s really not lucrative. I just wanted a fun story behind an engagement ring.
I actually mined the gold from electronics and those gold plated Pokémon cards they sold at Burget King for Pokémon the Motion Picture, but that’s another process.
Here’s how it goes:
Clean up your electronics. You ideally want just circuit board contacts. Like the strip of contacts on a stick of ram. Cut/break those off and dispose of the rest.
Soak in copper chloride. Use Hydrochloric acid (sold as concrete cleaner) and hydrogen peroxide. It’ll start eating at the copper on the circuit boards. 2HCl + H2O2 + 2Cu -> 2CuCl + 2H2O
Keep dissolving. This part takes a while. It helps to use a stir bar and bubbler to keep the fluid moving. CuCl will eat more copper and produce CuCl2, but you can “recharge it” by adding more HCl and bubbling in oxygen (or use hydrogen peroxide, but that’s more expensive).
Now you should have a bunch of flakes of gold that was plated onto the copper as well as the bare circuit boards floating around in a dark green solution of copper chloride. Pour through a coffee filter and wash with water to remove all the copper chloride.
To recycle the copper chloride, mix with sulfuric acid (sold as battery acid). CuCl + H2SO4 -> HCl + CuSO4. Boil off and condense the HCl to re-use. You won’t be able to get “fuming” 30% stuff like you buy at the store because the azeotrope of HCl is 20%. Then you can plate out the copper from the copper sulfate and reuse the resulting sulfuric acid. Copper sulfate is a super pretty blue by the way.
You do copper sulfate because plating copper out of CuCl2 will release HCl gas which is nasty.
Filter through another coffee filter and distill resulting solution to recover HCl and H2SO4.
Dry the filter paper, ball it up, and toss it in a heated crucible (I used a blow torch) with some borax to act as a flux. Eventually the paper burns away and you’re left with a tiny bead of gold.
So yeah, you can reuse the copper, Hydrochloric acid, and sulfuric acid, and the other byproducts are harmless salts and gases.
As someone who has personally mined 2.5g of gold from old electronics, I can confirm that while messy, there are no toxic byproducts.
In my setup, the only waste was hydrogen gas, CO2, and NaCl.
Of course I preprocessed my electronics to remove any solder or components, and you’re still left with the bare fiberglass circuit boards, so it may be different on an industrial scale.
Really can’t decide on a color temperature for those porch lights.
Though I really like the contrast the blue provides with the orange in the background.
What’s wrong with other sweeteners?
Let’s flip the equation here.
If driving wasn’t an option, you wouldn’t live 30 miles away from your job. Driving was an option, so you did and so did your neighbors. More neighbors move in, more cars, more traffic, more lanes, more neighbors, more cars, etc.
Alternatively, you move closer to work in a town with half decent sidewalks and walk or bike in. Bikes and people take up much less space which allows things to be closer together.
And yes, cars are necessary for hauling large objects over long distances, but how many vehicles in this photo do you think are carrying more than just people?
You also tend to not find them in the middle of cities. Texas just happens to be a car-dependent wasteland.
The problem is not with public transportation, the problem is that the area surrounding this highway was designed so that more cars and more lanes were the only possible solution.
Cars create problems that only cars can solve.
Edit: and to add more context: those 50 different locations are all separated by massive mandatory parking lots which make them miles apart from each other when they could likely all be contained in the same building in front of a single bus stop.
My solution? Buy an emulator handheld and get into retro gameboy games. Just finished Yoshi’s Island, Link’s Awakening DX, and working on Oracle of Ages.
Having missed the gameboy in my childhood, I’ve been surprised by how fun and engaging the titles are.
