    nobody thinking of a duckling as least scary? This did remind me of the time I was camping and woke up in the dark with an unknown animal with me in the tent. turned out to be a small kitten, so close to perfect!

    I used to work in a lab that used a bunch of thermoacoustic refrigerators, and we also used a bunch of other cool and bizarre physics-magic equipment (like "adiabatic demagnetization refrigerators", which use magnets to cool stuff down, and "transition edge sensor bolometers", incredibly precise thermometers using superconductors). The lab was full of physics PhD students and postdocs and a couple professors and they could effectively explain anything in the lab, which was full of incredibly complicated processes and equipment, EXCEPT the thermoacoustic refrigerators. Absolutely no one in the lab understood how the hell they actually worked, but they did a great job of cooling our fancy equipment down to 4 Kelvin. Sam's explanation was as good as anybody in that lab would have been able to do, maybe better.

    I feel like waking up with a puppy or kitten in my bed would scare me in that a) first touch: is this a rat? b) after seeing what they are: are there more of you and am I lying on any of them and killing them? and c) do I have to take care of you now?
    I think based off of where I live (Hawaii) a gecko would be the least scary/troubling thing to wake up to, though it would probably startle me initially, because I could just put it on the floor and go back to sleep. A cute friend that I don't have to take care of, that keeps pests away. A+ animal

    Lol hank just apparently hasn't ever registered the "family meals" freezer section. They sell those huge frozen lasagnas at kroger, walmart, ect.. they're just not always right next to thw single portions
    😂 he could order a huge fresh lasagna from Olive Garden if he wants it not frozen 😂

So, with that being said, this was another lovely episode 😊 Sending love from PA ❤

    Rv fridges can be run conventionally with electricity powering the compressor.
    They can also be run off grid using propane. The refrigerant is heated by a propane burner to evaporation, then allowed to condense, removing heat from inside the fridge box.
    Propane fired refrigerators have been used for decades and work really well.
    P.S.
    Thermo acoustic refigeration requires helium. There are limited sources of industrial helium, it is also difficult to perpetually trap helium, it is so light, it tends to escape over time.
    So production scale accoustic refrigeration would require material improvement, either in the refrigerant used or the infrastructure to hold the heluim.

    hank describing half of a heat absorption refrigeration system in the second question but having no idea was genuinely hilarious. lithium bromide and water is the refrigerant used in these systems, along with a waste heat input. its why they are potentially really efficient for server farms where there is a ton of waste heat already.

    i’d say that “what animal are you least scared of” and “what is the least scary animal to find in your bed” are extremely different questions if we factor in how they got there!! if there were like a bat in my bed that’d be really scary but i’d just be like “oh i left the window open” and move along. if there were a corgi puppy in my bed that would not be inherently scary but it would imply that a human person had come into my house and put it there 🙃

    A really good way to understand refrigeration better is to map out a comfort cooling system on an entropy graph for r410a. it makes it much easier to see the connection between pressures and temperatures. fun fact: many refrigerants decompose into phosgene or flurophosgene when exposed to high temperatures! how neat is that?

    • @shrededpudding5921
      @shrededpudding5921 10 месяцев назад

      It was really interesting seeing a perspective on the industry I work in from science communicators. Trying to explain what is going on in refrigeration without all the handy examples we have is no small task. the water bottle analogy is the perfect way to start to understand the concept because it really helps understand the sensible/latent heat difference.

    You really need to do a SciShow program on the JWST's sunshield and how it passively cools to cryogenic temperatures. There is a cool article on the NASA site explaining it in detail. Dustin from Smarter Every Day had a really cool show of his dad measuring the shape of the sunshield. The exact shape of each layer is critical.

    If you leave a glass of water on the bedside table for a few days, it tastes the same as melted ice. My guess is that it's due to dissolved gasses - if you pour either of these liquids from one vessel to another, they taste of normal water. I think the increased surface area of the flowing liquid allows better gas exchange.

    8:31 can confirm that it's possible to buy large lasagnas at Sam's Club. I'm allergic to beef, so I can even find premade family size sausage lasagna at various grocery stores sometimes. In fact we just had it last night and the leftovers are in my fridge right now 🤤

    Frigidaire. A lot midwestern folks in the first half of the 1900s (and a lot of old films) called it a Frigidaire and the midwestern accent definitely adds a d. Likely not well documented or the only true contributor but if you say frigid and refrigerator right now, which one sounds like you are adding that d in the word?

    It's funny how you're talking about not being afraid of dogs and how you totally can win against them in a fight. And yet, they are the number one killer of humans compared to all animals in the world. They kill more humans than sharks, rhinos, lions, tigers, and hippos combined. To be fair, part of the death toll is from rabies. I think it's a third of the dog kills.
