Today I Learned
What did you learn today? Share it with us!
We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

Fun fact in case anyone didn't already know but the diesel engine was originally powered by whale oil but it's such a resilient engine that it was later fueled by what was once considered a waste byproduct of gasoline refinement.
My understanding is it can actually run on a pretty wide variety of fuels (in general; not every specific model can run on a wide variety).
Biodiesel was gonna be the next big thing before EVs started gaining traction. Arnold drove around a Hummer that was modified to run on vegetable oil while he was governor.
Travel between the east and west of Australia is made difficult by a lifeless expanse called the Nullarbor Plain. In America, long haul travel is supported by the truck stops, which I understand to be huge complexes involving McDonald's and sometimes even entire malls. In Australia, it's a little different. Truckers and travellers are supported by the noble establishments known as chip shops. They sell chips. Sometimes with gravy. And there is always a shaker of chicken salt on a little table next to the door. And if you want some protein in your diet, then you can instead order one of Mrs Mac's Famous Beef Pies. Make sure to get a little squirty pack of tomato sauce. Many people have claimed certain things as universal Australian experiences and been wrong. Chip shops are the UNIVERSAL Australian icon.
There are chip shops on the Nullarbor Plain, but they're not connected to an electrical grid. Which means that until recently, you couldn't drive an electric car from Adelaide to Perth. But you can now. They installed electric car changers. And what powers the chargers? Why, a biodiesel generator that runs on waste oil from the chips.
Everything old is new again.
I was always told kerosene and diesel, in that order, were the products of interest. Standard Oil didn’t know what to do with gasoline because it was considered too dangerous and explosive to transport, so they bankrolled the development of the Otto cycle to power their own equipment.
It was originally designed to run on peanut oil.
