I'm leaving the shelter for the day soon and I don't know what it is, but today there sure were. People that came in. Here's a list of things that happened today in no particular order.

Someone came in asking to look through the dark types. We told them that many dark types are harder to raise pokemon, and have higher danger class ratings. Asked to see their trainer id. They refused, and tried to steal an employee's Purrloin. They were not successful.

Spent 20 minutes explaining to someone that water types do not just make water out of literally nothing, instead having large stores of water they can use to attack on top of supporting themselves. I should note, they did not think they were just combining the hydrogen and oxygen around them to make the water. No. They thought the pokemon just summoned water from wherever and argued with me for the full 20 minutes. They were a water type specialist with high placement battle records proving at least 15 years of experience with the type.

Visitor was looking for a fairy type. Decided to spend some time with a Ralts. Ralts decides it's had enough interaction for the day, and teleports away. Visitor then gets upset at us and tells us that we should "punish [the Ralts] for being a coward." Ma'am it is a Ralts.

Someone let a Mandibuzz out and I had to get it back into the aviary.

Three seperate people dropped Applin off. We are in Unova. Applin are not native. Please do not impulsively get people a whole pokemon as a gift, especially if you are having it transported from another region.

Got hit by an amoongus' spore. Twice.

A whole grown woman threw what I can only call a tantrum because she was told that her child could not pet a zweilous for his own safety. The kid was not even close to being as upset.

An Absol we've had for a while now named Timothy finally got adopted to a good home. Being a very stigmatized against dark type and an amputee, it was assumed Timothy would likely never be adopted but today nice family came in and decided to bring the Absol home with them! I thought you'd need a good thing that happened today as a a little cleanser.

The inner workings of Boothill

Trying to dissect him so, hear me out. (not too much tho, i'm not a car expert I just like looking stuff up)

I'd like to think he's powered by something similar to hydrogen instead of liquid fuel because;

This game has really advanced technology, so for someone like Boothill to still use the the 'old' fueling method would make less sense

The hole on his back is expose and if he had liquid fuel in him instead of compressed gas it would just...get everywhere. Not electric either because the fuel port only have 1 big hole as opposed to multiple small ones

No emissions this way, sure there's still steam but no harmful gasses and I think he'd prefer it that way.

It just makes a lot more sense for him to have a fuel cell instead of a fuel tank. Before I get into the more general headcanons I have I want to briefly explain how a hydrogen car is powered -

who am i kidding, this is a headcanon post not a chemistry class

oxygen + hydrogen go IN ⇒ energy + water come OUT

moving on;

I like to think looking after his body is something he takes a lot of pride in doing. It keeps him rooted and if anything goes wrong he'd figured it out fast

Has a temperature regulator close to his collarbone to regulate this head's temperature (since he doesn't have a body anymore). Takes in heat from the fuel cell and also has a coolant line running through it to adjust the temp.

He prefers mixing his own coolant using antifreeze and water over buying the premade stuff. Gives him more control over what goes into him and he just likes to keep tabs on everything about his body.

Distilled water only. Demineralized water? fudge no, and don't even think about suggesting tap water

Not too picky about the color but prefers blue, just makes it easier to check for leaks (yellow makes it look like he peed himself and red is, well, blood)

Flushes the reservoir once a year even thought that's not necessary. He just had it go bad once (the sickly sweet smell covered him for days) so he's not willing to take any risks

Doesn't need oil on the inside since the fuel cell has no moving parts but he does need lube for his joints. Has a preference for synthetic oil so yes, he still smells like oil. rejoice.

He takes in oxygen from various parts of his body and also expels a lot of vapor during fights, it's partly why he wears such little clothes.

The main inlets are the small holes under his chest but sorta outwards? These ones

And the holes in his hands as well. If you happen to touch those parts you'd feel some suction but he will get mad so maybe don't do that

Other less notable inlets are his chest + ab plates. They move apart slightly and can take in air if needed, but due to how much he moves around they're not that reliable, it's just a safety net.

He can store a small oxygen tank if he ventures anywhere with none of it (like in water or just on a planet with no air) but it limits his movements so he prefers not to.

As for the exhaust, it comes out from between the silver plate on his back.

Usually it's just low pressure steam. People wouldn't even notice it

but when he get's in a fight, he consumes more fuel, so steam can come out full force and hot enough to cause third degree burns to the unfortunate soul standing behind him.

If you listen closely you'll here his air inlets making noise too, it's why he gets very noise during battles.

It's hard for him to go stealth mission like this so he has a feature to block the exhaust when needed, it cools the steam down into water and stores it until he has time to empty it out.

In colder places he just straight up starts dripping water down his back when fighting. Yes it's safe to drink, no you can't lick his back maybe if you ask nicely he'll let y-

ps: DON'T drink water from a hydrogen car. The water itself is initially drinkable (literally just pure H2O) but by the time it comes out it's already been in contact with the inside of the exhaust pipe and you don't know what kinda dust/gunk gets in there.

any car experts/enthusiasts feel free to correct me lol. Everything here is just from 3 hours of surface level research

A well written explanation involving Lithium Ion Batteries. 👇

Understanding Thermal Runaway in Lithium Ion Battery Fires. Thermal Runaway Explained:

Thermal runaway is a chain reaction within a lithium-ion battery that can lead to catastrophic failure, resulting in fires or explosions. Here’s a step-by-step breakdown of what happens during thermal runaway:

1. Initial Trigger: Thermal runaway can be initiated by several factors, such as physical damage (e.g., puncturing or crushing), overcharging, manufacturing defects, or exposure to extreme heat.

2. Internal Heating: Once triggered, a part of the battery starts to overheat. This can be due to an internal short circuit or a chemical reaction within the battery.

3. Chain Reaction: The heat generated from the initial trigger increases the temperature inside the battery. This heat can cause other parts of the battery to react, generating even more heat.

4. Rapid Temperature Rise: As the temperature rises, the electrolyte inside the battery—a flammable liquid—starts to vaporize and decompose, producing gases. This further increases the internal pressure and temperature.

5. Gas Release and Ignition: The increasing pressure can cause the battery casing to rupture, releasing flammable gases. These gases can then ignite, leading to a fire or explosion.

6. Propagation: If the battery is part of a larger battery pack, the heat and flames can spread to adjacent cells, causing them to undergo thermal runaway as well. This can result in a large, intense fire that is difficult to control.

Key Points: - Difficult to Extinguish: Thermal runaway fires require massive amounts of water to cool the batteries and stop the chain reaction. Traditional fire extinguishers are often ineffective.

- Toxic Gases: Burning lithium-ion batteries release toxic gases such as hydrogen fluoride, which can be harmful if inhaled.

- Reignition Risk: Even after the fire appears to be extinguished, there is a risk of reignition. The battery cells can remain hot and unstable for hours or even days.

Safety Measures:

- Distance: Establishing safety distances to keep people away from the danger zone.

- Continuous Monitoring: Using thermal imaging to monitor for any signs of reignition.

- Specialized Response: Firefighters need to use specialized techniques and equipment to handle lithium-ion battery fires safely.

Understanding thermal runaway helps in appreciating the complexity and danger of lithium-ion battery fires, highlighting the importance of safety precautions and effective response strategies. 🤔
