Technology@lemmy.world•'It doesn’t catch fire': Why China’s "fireproof" sodium battery could be the breakthrough that makes EVs safer than ICE carsEnglish

I seem to remember that there is some dangerous dissease that people mainly catch from puppies.

Unpopular Opinion@lemmy.world•I think amp-hours are confusing and I wish they just gave us battery life figures in joulesEnglish
2·7 days agoThat’s not strictly true, the voltage of the battery changes as it discharges, so you technically need to integrate the area under IV curve.
Yes but a fully charged battery will also have a voltage higher than its nominal voltage which mitigates that quite a bit. Also as I said in my origional comment, the rated capacity is only ever a rough measurement anyways so while volts×amphours=watthours isn’t perfect, it’s close enough.
or anything that let’s us compare across voltage
I guess the part I’m missing is, when are you ever really comparing across voltage. Generally when you’re shopping for batteries it’s for a specific application and that application will have a specific voltage requirement. So you’re only ever really going to be comparing batteries of the same voltage anyways. It isn’t like you can just toss a 48V battery in something that requires a 6V battery.
Although I do agree that a voltage agnostic capacity measurement would be nice. My personal preference would be watt hours.

5·7 days agoYes but when are you comparing batteries at different voltages? If you’re comparing batteries for a specific application then you’re going to be looking at batteries of the same voltage.

6·8 days agoWhy joules instead of watt hours? Also amp hours is simple to convert into watt hours. If you know the voltage then volts × amps = watts. So a 12V 100AH battery is 1200WH.
Also bear in mind that battery capacity measurements are only ever really approximate anyways because the actual capacity will vary based on how quickly you draw power from the battery. The more amps you pull the lower the capacity.
That’s actually what they dope the silicon with, one really angry water molecule.
So is water. Hard to beat a miracle fluid that covers most of our planet.
Somebody linked above to a new closed loop turbine design which uses supercritical CO2. I know from CO2 refrigeration that CO2 has some insane volumetric expansion based on temp which makes it a good candidate for use in a closed loop turbine system. Plus, because they’re running it through the turbine as a supercritical fluid, the density is higher than that of steam so it requires smaller turbines. The biggest issue is that because it’s super critical CO2 youre talking about working pressures well over 1000PSI. That doesn’t make it impossible to work with as we already know from CO2 refrigeration, but it does make it a bit more difficult than just boiling water.
My mom insisted on taking me on a cruise for my birthday. I left that boat wanting to full blown Ted Kaczynski.
A cruise ship is just press where the wealthy wring as much money out of people as possible. You’re there to drink and gamble. If you don’t like doing either of those then you can go to any one of the dozens of events where people are, surprise surprise, drinking and/or gambling. I guess there were a few events that were just marketing for scummy tat or services too. There is nothing you can do that doesn’t cost money even with the “free” perks. We had a free drink package but god forbid you forget to tip for every fucking drink including if you just want some fucking water. Oh you one a free massage? Well guess what, it’s not actually free. It’s free after you buy the base package. Plus at the end of the cruise they automatically charge you a $160 “gratuity” just for existing because fuck you. The whole thing was unabashedly scummy; It felt like spending a week trapped in a car dealership.
Our time off the boat was at tourist trap islands which had all been pillaged so thoroughly that tourism is now all they have. Some of those islands still had some natural beauty but looking at it also just pissed me off because there was nowhere you could look and not see what little remained being actively destroyed. The snorkeling trips were even more infuriating, nothing quite makes you hate people like snorkeling in dead garbage filled reefs.
I want to see every cruise company executive sent through a woodchipper feet first. I want every cruise ship turned into an artificial reef.

United Kingdom@feddit.uk•Camera issues £600k in fines for illegal turning on one of the “most dangerous spots for cycling in UK”English
23·11 days agoNah, if that many people are doing something wrong at this roundabout then there is clearly something wrong with the roundabout. I’d say hopefully the government uses all that earned money to actually fix the problem but we all know they’d rather just plonk down a camera and fine people than fix the roads.

Ask Lemmy@lemmy.world•Showers, morning or night?English
2·11 days agoNot necissarily blue vs white collar. Probably more just customer facing vs not. I’m a service tech so I’m blue collar but I’m also directly interacting with customers so I need to look presentable at least at the start of the day. So I normally do a morning shower so I look presentable to customers but sometimes I wind up crawling around in unspeakable filth or working up a major sweat at work so if that’s the case then I will do an after work shower in addition to the morning shower. But I’m customer facing so the morning shower is a must.
