Showerthoughts

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts:

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct and the TOS

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

And I thought they were supposed to be shying away from fossil fuels.

Tesla owners going from "Look at me!" to "Stop looking at me!" in the blink of an eye.

[–] [email protected] 59 points 1 month ago (12 children)

if i were looking to fuck with a Tesla, i'd pay close attention to any indication that the car was purchased recently. there are a LOT of people out there with a murder fetish, and i GUARANTEE that a lot of the nice new ones out there are really bait cars for gun owners that have been dying for a reason to shoot someone.

[–] [email protected] 37 points 1 month ago (1 children)

Yeah, probably a lot of Rittenhouse wannabes out there who wanna test the limits of castle doctrine.

[–] [email protected] 38 points 1 month ago (15 children)

yes, but this is a whole new monster..

  1. someone shoots a person who's defacing their Cybertruck
  2. they're convicted of murder because it's proven they bought the vehicle specifically to bait a victim
  3. Trump pardons them

i defy you to tell me that this isn't INEVITABLE.

[–] [email protected] 23 points 1 month ago* (last edited 1 month ago) (5 children)

Man I don't even think step two would happen before trump pardons them. The US is so fucked.

EDIT: As an example of what you said, a sociopath who has recently bought a Tesla is the fucking president of the US

Murder ia basically always handled at the state level, so Trump would not have power to pardon that crime.

[–] [email protected] 23 points 1 month ago (1 children)

He doesnt have the power to do lots of things he is doing.

[–] [email protected] 7 points 1 month ago (1 children)

Tell you what's more likely? DeSantis or one of those babyfuckers will do it.

I know it's a joke, but many Tesla "solar" charging stations did actually use diesel generators a few years ago. Citation needed, but I can't be assed to look up the article.

[–] [email protected] 36 points 1 month ago (6 children)

Still more energy efficient than a regular ICE car.

[–] [email protected] 24 points 1 month ago* (last edited 1 month ago) (2 children)

Debatable, it depends on what fraction of the power was supplied by the generator. The chemical-kinetic-electric energy conversion incurs great losses because of waste heat, and portable diesel generators are not always built with efficiency in mind. A charging station operating on 100% diesel to power an EV is much less efficient than a modern ICE vehicle of a similar mass sans batteries.

Citation needed. Do ICE engines not get hot and therefore also have great losses because of waste heat?

Presumably a generator making electricity for a charging station would only run when electricity is needed, while an ICE engine would be losing energy to heat the entire time the vehicle is idling in traffic.

Why would a diesel generator not be made to efficient and why are ICE engines always made to be efficient? How do you know which kind of generator they were using? Why would they use the generator for 100% of the energy needed?

[–] [email protected] 9 points 1 month ago* (last edited 1 month ago) (3 children)

Keeping in mind that this is a hypothetical scenario and that I did point out that the overall efficiency is dependent on how much of the power is generated by renewables and how much by the on-site diesel generator:

  • An ICE skips the conversion to electricity and its storage. Losses and losses.
  • An ICE vehicle weighs less than an EV of a similar size because it doesn't have batteries (see this chart to compare the energy density (MJ/kg, horizontal axis) of lithium batteries to gasoline and diesel)
  • There is a point in the diesel/solar ratio at which the system's overall efficiency is higher with an EV than an ICE, but I don't know where that is because, once again, you're pissing yourself over a hypothetical scenario.

Last I ran the numbers, it seemed like on paper charging off an industrial scale generator was around 20-30% more fuel efficient per km than directly running an ICE car, but I based it on the advertised efficiency values of a random average seeming diesel car, compared to rather pessimistic charging loss and efficiency numbers for the EV. The inefficiency of even modern ICE cars is quite astonishing, even compared to the engine in a generator that can constantly run at the optimal RPM and load for efficiency.

Not to mention the electrical energy stored in their cells has a fairly strong possibility of having been generated by a power plant consuming coal or petroleum.

[–] [email protected] 27 points 1 month ago (4 children)

I live in Alberta where most of our power comes from natural gas. I'm also an emissions and sustainability engineer. I did the math on environmental payback for an EV where I live and the EV is WILDLY better for the environment despite the power potentially coming from fossil fuels.

If you tell me roughly where you live I can calculate emissions per kilometre/mile including the energy that goes into manufacturing the vehicle.

There's absolutely jurisdictions where EVs don't make much difference - but most places they do.

(large scale power generation is pretty effecient and most jurisdictions have some renewables in the mix. A car's gas engine is much lower efficiency most places)

Even when powered by fossil fuel power plants, electric vehicles are still usually better in terms of CO2 emissions. Power plants benefit from scale, so they're a lot more efficient than the tiny combustion engines in cars. Regenerative braking also saves a ton of energy when driving in the city.

Yes the fossil fuel industry loved to point this one out. "Hahaha! We're so dirty even your clean tech can't be clean!"

Teslas don't run on gasoline.

It runs on them.

I am so slow lately I saw this yesterday and only just now got the joke

Let's focus on the nazi leader also not only his old projects

[–] [email protected] 31 points 1 month ago

His stock in Tesla is leveraged for a lot of other things he does. Lowering the stock value could cripple him financially.

[–] [email protected] 14 points 1 month ago (3 children)

Run Tesla stock prices into the ground. It's legal and, short of criminal violence, it would damage Elon worse than anything else. Without his money, Elmo Muskrat would just be the guy at the end of a dive bar you avoid because all they talk about is government conspiracies to cover up the fact that Lizard People Aliens are making human lizard people hybrids.

Actually burning Teslas is bad for the environment.

Drop in the bucket compared to what enabling this billionaire shit bag is going to do.

You don't have to use fossil fuels. Just pointing out.

This is America. We use corn based moonshine here.

[–] [email protected] 11 points 1 month ago (1 children)

Tito’s Vodka is distilled from corn.

[–] [email protected] 7 points 1 month ago (8 children)

today i learned! the defining characteristic of vodka isn’t the raw ingredient but rather the distillation and filtration process that makes it a neutral spirit.

according to the U.S. TTB (Alcohol and Tobacco Tax and Trade Bureau) and the EU regulations, vodka is:

  • a neutral spirit distilled to at least 95% ABV (190 proof) and then diluted to no less than 37.5% ABV (EU) or 40% ABV (U.S.) before bottling
  • usually filtered, often through charcoal, to remove impurities and flavors
  • can be made from any fermentable sugar or starch—grains (wheat, rye, corn), potatoes, grapes, even milk whey
