Acids don’t work as well on the substances that contribute to typical household drain clogs compared to bases, which is what Drano is.

When it enters your drain pipes, the sodium hydroxide reacts with fatty acids and proteins from your typical clogging culprits like oils, grease, soap scum, hair, and food particles.

This reaction generates heat, breaks large molecules into smaller ones, and liquefies solid gunk. The extremely high pH enables the sodium hydroxide to saponify fatsand dissolve organic matterthrough chemical decomposition.

Acids simply wouldn‘t have the same cleansing effects on drain clogs. Grease and oils are composed of tough-to-break-down fatty acid chains that resist acidic breakdown.

Asked what he thinks about a presidential candidate speaking about batteries this way, Sadoway laughed. “Are we talking about the scientific literacy of any candidate?” he said. “I question the scientific literacy of anybody who’s running for president.” He added: “There are so many battery posers out there who don’t know the cathode from the anode.”

Absolute battery chad

No law prevents a convicted felon from running or winning the office of the presidency. As for the question of self-pardons, that’s something that everyone on both sides would hotly debate as it’s never been tested before. You would think there’s an obvious answer (he can’t) but unfortunately laws get fuzzy at the very top and decisions are usually dictated by historic precedent (which there is none for this scenario in US politics.)

Or worse comes to worse you can take it to a mechanic of your choosing.

That’s also what I meant when I said “taking it in.” In either case you’re taking your car somewhere to get it repaired for X hours instead of applying an update at your home.

A Tesla battery is expensive…now look at install costs. And if you’re not using an authorized installer, you’re locked out of the supercharger network.

We aren’t talking about batteries.

I just think there’s more nuance to the situation and saying that cars should be as inconvenient as possible to fix isn’t a good solution to lazy auto software that requires future patching. Rigorous safety testing and regulation around car software sounds like a better plan to me- automakers will be held to really high standards and the consumers will still benefit from simple OTA patches to fix their vehicles when necessary.

Think of the inverse though- it used to be that in every case when your car had an issue you needed to either take it in yourself or have the technical knowhow to fix it yourself.

I do agree that it’s a slippery slope for automakers to get lazy and cut corners, but I think stricter regulation is the better solution than forcing an unnecessary inconvenience onto the customers.

Put your hate for Tesla aside for a moment. If a car company can fix an issue with a simple OTA software update, it’s way more convenient for both the customer and the manufacturer. Quality control of an update is a separate issue but I don’t imagine there’s a difference whether your car updates itself or gets taken in for the update- the same patch gets applied in either case.
