No problem, hope you enjoy! Other science/engineering based channel recommendations (trying not give too many): Thought Emporium, SuperFastMatt, Michael Size, and Hyperspace pirate.
Again, no problem. I actually just recommended SuperFastMatt to a coworker the other day, because I figured he'd get a kick out of the off-road viper he's been showing the process of making.
I disagree with this man on his intro material. If you're looking from first principles, gasoline is actually, for its energy density, an incredibly safe material.
It seems like this crazy dangerous thing, but that's only because of how much energy is in it. Think about if all you knew about was hydrogen or LNG or propane, and what the gas pumps and storage containers and fuel tanks in the cars, and the process of putting the gas in or getting a can to put in your lawn mower or whatever, look like. Like, you know those videos of someone with a propane-modified car who gets in a fender bender and the whole car suddenly explodes into this massive fireball?
Now imagine someone telling you they have a fuel that's useful at room temperature, it's liquid and stays where you put it, and as long as you keep it away from fire and sparks, it won't ever really do anything. It's not under pressure. You can spill it on yourself and wash it off and you're fine. You can work with it every day and it's not great for you over the long term, but you won't get any immediate kind of poisoning. Even if you're near a fire that's burning it, it won't do anything toxic unless you're in an enclosed space with CO building up. You can literally stick it in a can and carry it around, or a bucket if you're a little bit brave. You can literally rupture the car's fuel tank and spill it all over the ground, and it's dangerous, but even then it's not an automatic explosion. And still, a few gallons has enough energy to throw this massive multi-ton metal monster around at unimaginable speed for hours.
Batteries are the only thing that's even close, and they have some other advantages, but the "buckets" are super expensive and complicated, and they also have these massive crazy failure modes that are way worse than a gasoline fire, and you have to take incredible precautions with designing your systems to make sure the humans never touch the energy part.
Gasoline is great. There's a reason that for about 100 years it was the only viable option and the rate of accidents is pretty low even with it in use every day by average everyday idiots on a global scale.
My school had a field trip to something like this but we actually learned things. I learned how to read an electric meter, a water meter, and how to write checks (the only way you were allowed to "spend" your "money") other kids learned how to run a register, and various other civil government and utility type things
I have extremely deep memories of scanning plastic groceries. But it couldn't have been at one of these locations (we'd never go to Mexico for this, and the one in Florida we'd have been juuuust young enough to get in so probably not)
We must have been at a museum, but where were you, memory of scanning wee little groceries?? Probably some museum in NYC or Philly???
If you try to watch them on the mutualofomaha site they’re sadly heavily edited and complete shit. The videos on that site edit the original episodes from the 60s and repackaged them with a new host.
Was able to find full length videos on internet archives. The episode from this clip is called Land of the Quaking Earth.
Is it because it's a stupid idea? I didn't watch the video because it's 44mins and it's just a stupid idea right off the top.
Do you know what isn't a stupid idea? A circle. Same plans, same god awful location, just make a big circle and double function the thing as a particle accelerator.
tl;dw - MBS murders anyone who opposes him, so no one will tell him it's a bad idea (Jamal Khashoggi voiced opposition to the plan).
Also, it's a bit of a stunt to attract tourists (compared to something like the Burj Khalifa) and has a bunch of promises that are just patently not viable, as opposed to an actually thought out project.
~24m into the video, the proposal for a circle is dropped in as a better alternative (albeit still crazy)
So they actually thought of doing a circle? OMG! My sides!
If there was a god, you know he purposely gave the dumbest people in the world the most amount of money for his own amusement. While I am sure there are some brilliant engineers working on this project, you know damn well what they are thinking.
The circle was proposed by experts who said "if you're going to build something this dumb, a circle will require much less space and cause less problems for animal migration patterns" and promptly ignored by MBS.
So, as they say, I did my research. In a completely unrelated note I found that toddlers, in their infinite wisdom, tend to gravitate to circles and circular scribbles because it is naturally more efficient. The only natural conclusion is that infinite money cannot actually replace proper childhood development. https://lemmy.ca/pictrs/image/60ef612a-b85b-4419-bd84-a60a6fffb208.jpeg
Damn, I was really hoping he’d have something I hadn’t tried. Most of these are just “how to use a dishwasher” stuff I learned as a kid. And my dishes still don’t get clean.
I use the lemishine shit in every wash, because I have very hard water, and frankly it’s still not enough with all the other tricks to actually clean my dishes if they aren’t already kinda clean..
The big downside of running acid through your dishwasher is that it will strip paint off stuff with continued use. Lost a bunch of kiln-fired printed glassware this way. Don’t recommend.
I do have a whole house polyphosphate water softener I need to install, which I’m hoping will help, but my city is doing work on the water mains, so I’m holding off until that’s done.
He may have been, but they have several products and what he was showing is the detergent booster, I believe (linked below), and not the machine cleaner which is used periodically (which is just a stronger form of it that you run without dishes in, and comes in little packets - great for cleaning hard water marks from toilets!)
He did point out dishes should be loaded with the dirty side towards the center. I'd always thrown everything in facing the same direction and my dishwasher handles it fine, but his way makes sense.
