This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

Be warned:

If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

I cannot have my own nuclear reactor, but the state can build nuclear power plants, wheres the fairness, wheres the freedom

[–] [email protected] 19 points 4 months ago (1 children)

You just need to stop telling yourself you can't do things and do whatever you want. A child could build a nuclear reactor, so what's stopping you?

Meanwhile, TSA: no water bottle for you. Bring a cell phone, laptop battery, and a spare 20,000 mAh backup battery (of dodgy provenance no less)? Sure no problem.

Loved this when I was vaping and would travel for work.

Give me a ton of shit over my variety of juices, in 30mL bottles in my 3-1-1 bag...but the half dozen loose 18650s? Not a problem.

(They weren't totally loose, I had silicone sleeves on them and would rewrap them if they showed a little wear on the wrapper. I used mechs and RDAs, I wrote the newbie guide to rebuilding on reddit...I was pretty safe about it).

Assumably the bus company would be buying the bus from a company with better quality control then the Chinese ones. There were some knockoffs "hover boards" that catch on fire and that Chinese bus fire.

Battery Management Systems aren't some new, developing technology. We know how to safely manage Lithium battery, it's just the certain manufactures are cheaping out on the battery packs and BMS. People didn't all stop using their phones because of the Note7 fires. People didn't stop driving cars because of the Ford Pinto. They need to get over their EV fears and be more discerning

In Northern Ireland during the Troubles, people put (time)bombs on busses and when the bus driver heard about it, he just went and lifted it off the bus and put it in a ditch at the side of the road and informed the police. Couldn't be bothered with evacuating the bus in the middle of nowhere.

Cheap eBike batteries have and do set on fire though. Sounds pretty terrifying.

[–] [email protected] 11 points 4 months ago (2 children)

There is a clip circulating recently of a guy in China carrying his e-bike battery into the elevator. Than that thing explodes and the guy dies in a sea of flames. Yeah carrying a cheap high capacity li-ion pack into a enclosed space is not a good idea.

[–] [email protected] 5 points 4 months ago

Quality control exists to ensure li-ion batteries don't spontaneously combust, or at least not as often. Same reason why old timey film reels were kept under very carefully controlled environments, those things can also spontaneously combust. Any place that allows QC to be skirted will result in accidents and deaths like that elevator guy.

To be fair, there may not be another option if he needs to get that to his flat and there's no ground storage.
Horrifying.

There's a video circulating few days ago of electric scooters on a truck delivery catching fire. The funny thing the fire happened right under an Ioniq 6 billboard.

Me with an e-scooter charging at home:

[–] [email protected] 10 points 4 months ago (1 children)

If it's a cheap one, only charge it while home or somehow isolate it from flammables. Keep a fire extinguisher nearby always.

[–] [email protected] 6 points 4 months ago (1 children)

An extinguisher that can actually handle Lithium fires though. A regular CO2 extinguisher wont do anything against burning Lithium

I was looking up e-scooters and a bunch of 1-star reviews pointed out how their battery caught fire.

Could have been fake reviews by competitors but either way, it freaked me out.

[–] [email protected] 3 points 4 months ago

A home here burned down. Stay safe kids.

[–] [email protected] 7 points 4 months ago

It's certainly an issue with some of them. I wouldn't buy a random no name one from alibaba. It might be safe. Or not.

[–] [email protected] 16 points 4 months ago (2 children)

A lot of them will be fine but some of them are cheap knockoffs and they have unsafe wiring. It's not actually the batteries themselves as they'll probably be the same batteries it's the way the batteries are connected up that makes them more likely to explode.

Unless you are Samsung in which case it 100% was the batteries at fault not the wiring.

[–] [email protected] 5 points 4 months ago

Lithium batteries have a very high energy density. When that's released all at once with a short circuit or very high current draw resulting in thermal runaway, that's when these fires start. The great news is, they're self fuelling fires too!

But, most reputable manufacturers, create charging/protection circuits that protect the batteries against such situations. Making them far less likely (but still possible) to happen.

The problem you're going to get is when there's disreputable companies, operating in countries with less stringent safety laws that are operating the production, processing and shipping entirely outside of the sight of countries with safety rules. Well, then you get a product with a fake FCC/CE sticker on it, that is very dangerous indeed.

I will not buy electronics from those sites for this very reason. Batteries, chargers and power supplies are usually very shoddy from these companies.

It's not to say don't buy stuff made by country X. Because there's plenty of stuff I have bought made in, these countries but sold by companies that DO make sure there's some testing done, and they're not fake stickering everything. But, we all know the companies I'm talking about I think. Also, ebay (because private sellers buy in bulk from these places and then resell them) is something to be careful of too.

I keep my scooter at the farthest point from the apartment exit just to be on the safe side. I also haven't heard many bad things about this particular model (Ninebot G30 Max).

[–] [email protected] 50 points 4 months ago (1 children)

People used to say the same about cellphones.

I remember one episode where a girl in the bus was texting and some old lady got up to tell her that "it will go into the engine". The old lady was terrified.

[–] [email protected] 28 points 4 months ago* (last edited 4 months ago) (1 children)

That reminds me of something.

Also on a bus. There was a group of girls on the bus and they were having a big loud argument about whether or not one of the group would receive a text from her partner or friend or whatever because "how would the text know where they were, as the bus is moving".

[–] [email protected] 28 points 4 months ago (1 children)

A valid question. Luckily a lot of work has been done to address it.

[–] [email protected] 4 points 4 months ago

Pretty much the first thing that needed to be solved when moving from 1-way pagers to 2-way phones. Pagers could just get a broadcast analog signal and determine themselves if they were the intended recipient. 2-way needed more bandwidth and a dedicated communication channel to a specific device, so broadcast wasn't feasible. Thus, phones would send a registration signal that a tower would pick up, and that specific tower would handle all communication to that phone. If another tower got the registration signal, communication would switch to that tower.

Interestingly enough, there was a period (for a fairly long time) that if you were travelling too fast, you could either a) not be able to register on a network, or b) overwhelm the network with registrations - part of the reason why phones had to be turned off on airplanes

Slight difference in build quality, wouldn't you say?

It does happen. Not like the bus driver has time to check the battery has all its relevant safety certs.

[–] [email protected] 10 points 4 months ago (1 children)

Yes, but at least someone is actually checking the bus battery.
