The cheapest way to do it would be to have a sample line connected to the Dutch oven (metal line) that's attached to a dog-eared beaker (with rubber tubing), with the other ear of the beaker being a line attached to something pulling a vacuum (like those vacuum nozzles in chem class connected to the sink outlet). You then place this beaker on a hotplate that keeps it warm (so you don't condense on the glass) and you have a stainless steel cylinder with a rubber outer stopper ring thingy (to seal the beaker). You heat some water to say 190 (I doubt your dew Point is above this temp lol) and then add it to the cylinder. Place a thermocouple in the cylinder and blow air lightly into the tube to lower the temperature. When the cylinder fogs, you have the dew Point temperature of the atmosphere from within the Dutch oven.

Source: This is the same process for getting a dew point of your furnace atmosphere in an industrial setting. The concept is known as a "chilled mirror" dew Point. There are continuous devices that can determine this, but the manual method is cheaper/can withstand higher dew points

If you went for a method using a digital hygrometer, you would still want a sampling line that goes from the Dutch oven, to outside the oven because I'm not aware of any hygrometers that would work in intense heat unless they had their own cooling jacket + cooling system for the mirror & sensor

note: I am trying my best to get a picture of this setup, we use them at work, but searching online is mostly returning inline, digital hygrometers

Edit: Okay, I drew it instead on a sticky note. When the cooling water in the tube makes it fog, that temp on the thermocouple is your dew Point

Well, if they just inherit their dead dad's debt, would that be a "good life?" Assuming a financial situation is why this occurred. If both parents die is the debt expunged or passed to next of kin? If the debt is passed, they would be forced to declare bankruptcy early in their life (destroying their credit), which destroys a lot of options like college, car ownership, etc.

By no means am I saying this is the better option, just seems like both were quite shitty outcomes to me

Googling a rough average returned 0.346 kwh/mile for electric cars between 2000 and 2022 (wide range, im aware). Traveling at 50MPH, you go 50 miles in 1 hour (assume you're already going 50, and stay at that speed). So you'd use [0.346KWh/mile] *[50 miles/hour] = [17.3 KW] per hour @ 50 MPH

I torrented and seeded many torrents (its still seeding right now) and it can do at least 2 (havent tried more) jellyfin streams at once as long as I disable server side transcoding to reserve resources. I had the full arr suite of apps running along with ombi (gonna move to jellyseer, but imo ombi used too much ram on my 4GB laptop to be something I kept running). Is it perfect? No, it has quirks that will come up now and again but can I really complain when getting now 16 years of use out of a laptop I never thought I'd touch again once I built my desktop?

Edit: oh be aware, if you're using old hardware, DO NOT use the newest versions of things like Linux mint, it possibly won't have drivers that works for really old hardware (like wifi card, Lan card, etc.) and it won't be easily apparent sometimes. I solved this with a friend who had the same laptop as me but couldn't get internet once installing mint. It turns out he used a newer version of mint that did not have a way to support his wifi card and installing and older version solved it

I run some of my services (until very recently including jellyfin) on my HP pavilion G6 from 2007. It still runs my wireguard, backup pihole, heimdall, etc. I run it on Linux mint (it was familiar) and cant do most things on screen (lags hard) but I can ssh or VNC in just fine

Yes, in a sense. It technically isn't vibrating them, but rapidly spinning them due to the constantly changing magnetic field (produced by the magnetron).

Since water has a dipole moment (one side of the molecule experiences a slight positive charge, while one side experiences a slight negative charge) it will react to changes in an electric field just like a magnet would

Edit: I'd also like to add this is not specific to water. Some fats and other food material also undergoes that rotation, and the same concept (with different frequencies and wavelengths) is used in industrial processes all the time to quickly, and efficiently heat materials

As a process engineer in a union steel mill, can confirm

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'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

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