You would use materials that perform completely fine at those temps. This could be anything from high nickel alloy steel, to Inconel, to an HEA (high entropy alloy). You can even do high heat resistant metals with ceramic coatings on the inside for protection if creating a passivation layer is too difficult for the application or the exposure environment does not allow for one to form.

There is an entire subsection of engineering studies focused on purely coaxing specific properties out of a material or developing materials to custom suit extreme applications, known as material science. They generally work very closely with chemical engineers (my background) and metallurgists in order to manufacture the designed product in either batch form, or in continuous fashion.

I work in a steel mill and we have Inconel furnace rolls that hang out in 1600 F heat 24/7 and are rated (iirc) to ~2300F max operation temp. For reference medium carbon steel melts between 2600 and 2800F, and loses a lot of its mechanical strength well before 2300F (I am trying to find a stress strain curve for carbon steel over multiple temperatures for reference. I will update if I find one)

Edit: Okay so I found one that does show what I am trying to convey. As you can see, the higher the temperature of the sample material, the lower the yield strength. Example: the 100C sample was strained to >25% before failure, while the 700C sample began to plastically deform (fail) before 10% strain. Take note of the second link, all the test temperatures are MUCH higher than any of the carbon steel samples

Where are you getting the 45% number? I am seeing petrochemicals (plastics, resins, and petroleum based feedstocks) @12.12% of total oil demand in 2022. I see that road (all forms of shipping and transport on roads/care with petroleum products like tar/asphalt) is 49.24% of demand.

Diving deeper into the transportation sector, light trucks + other trucks make up 57% of the transportation sector's petroleum usage. Following with cars/motorcycles @21%.

I agree with the sentiment you raise, that industry accounts for a very large portion of crude oil consumption, and that isn't going anywhere anytime soon. I just am unsure where you saw your data or if its perhaps looking at a different region specifically?

Yes, I should be able to play music, AND charge the phone without a 9 wire adapter like those universal charger plugs from 10 years ago. Wild concept. I wonder when phone tech will be able to support such a thing

I watched this video last night with my girlfriend, and it answered SO many questions I had about how they worked. The last time I touched a sewing machine (besides my seamstress grandmothers ancient singer that popped out of a table) was in middle school for home-ed class. I am a chemical engineer now, and it still baffled me that the needle only partially penetrated the fabric, yet a full stitch was completed. I was completely unaware of the mechanism inside the base that was allowing for the back side of the stitch. I sent this video to 3 other engineers I work with and we all found it very insightful/interesting to see how such a machine was developed.

I'm still running one of the early versions completely fine. I wonder what might be different on your end. I would update but I'm honestly unsure the correct way to update revanced

The issue in my eyes, and my number one complaint with this massive E.V. push (for many years now) is the insane environmental impact of lithium mining and the very short termed planning of just going hard on batteries (without spending more time and money on better battery tech [Toyota actually has that new solid state battery I'm very hopeful for, and we've been working on polymer batteries for decades]) we will waste a very precious earth material we WILL NEED in the future, and you never ever hear any of the politicians or CEOs talk about how dirty lithium mining and processing is because almost all of it happens outside the countries leading this push (thus, not their problem).

Not saying we shouldn't be moving away from ICE, it's that I feel our current approach is incredibly short sighted, and will have far reaching impacts into future generations and I feel as though we may even cause more damage than help in our current approach

I watch totally fine on my phone and pickup at home. It should sync to your log in account in my experience

Having been involved in plant shutting talks in the steel industry. You'd be shocked what companies are willing to do

They very much can, will, and do for much less. Welcome to an "at-will" employer. The only thing that's illegal is discrimination

I would be jealous, if sitting at a desk didn't make me wanna hang myself with an ethernet cable. I'm a process engineer in a steel mill and holy sweet fuck did I wanna die when I was WFH as a desk engineer. Bored out of my mind and feeling like I'll never progress because I couldn't even network well with managers/engineers like you can in a mill/in person office.

That's when I learned at this point in my career, heavily WFH is not for me. I need challenged and I need hands on, 1 of those I very much cannot get at home

It is for most companies. You put the drive into a mileage calculator for your company and they reimburse you a certain amount per mile. You don't do napkin math, they need legitimate records for accountants, audits, etc.
