    Watt-Hours are quite possibly the stupidest measurement of energy. „Oh let’s take a unit of joules per second and multiply it by a bunch of seconds. What do you think we get?“ Apparently not fucking joules.

    And then applying SI prefixes to them? Absolutely perverse.

      Why use Joule, just use kg*m²/s².

      Square meter kilograms per second per second is even more intuitive.

      But more seriously, Wh and kWh is much more intuitive when determining energy consumption of your household. I don’t want to calculate how many joules my fridge consumes per day!

        Joules, as is the international Standard. 1 W•h = 3.6 kJ. One of the issues with watt-hours is that they’re so unconventional a unit that people think they’re a rate of change (Watts over time - W/h) which would be a measure of the fluctuation in wattage or colloquially an acceleration of energy. You so often see people doing crazy broken math with them as a result.

      It’s not that bad. If an electric kettle runs on 500 watts, and you run it for one hour, then it consumed 500 watt-hours. What’s the big deal?

    The way the artist wrote k made it look like the Greek letter mu, and I thought it was taking impossibly small amounts of energy to boil water.

    Last time I stayed at an Airbnb, all their pots were nonstick and scratched to shit. I made pasta a couple of times in the tea kettle. I try to avoid nonstick in general, but when being used communally, there is no fucking way I can trust that people have treated it right, and as much as my body craves Teflon as a fuel source, I will do everything in my power to avoid it, including cooking in a tea kettle.

    I don’t know why I’d buy another appliance specifically to heat water, when I have a general purpose microwave that can do it just as well.

    Here are the three things I use my microwave for in order of amount of use:

    Heating water for coffee
    Cooking vegetables
    Thawing meat

    I run my microwave about 17 minutes per day total for those three tasks.

      One could argue the same about why get another appliance (microwave) when they already have the general purpose stove that works just as well

      Microwave is usually 900W while a Non-US kettle can do 3000W on a standard 240V 16A connection so it boils water more than 3x faster.

      Very convenient for serving tea and instant coffee and also useful for cooking potatoes, veggies, rice, pasta by boiling water first before pouring it into a pot for a quick start.

        Microwaves are usually 1000 or 1100 watts, in the US at least. Only the cheapo Walmart microwave I had in college was 900W. A kettle in the US is still more powerful and faster at up to 1500W or, less commonly, nearly 1800W.

      You can get a small electric kettle for less than $20 that boils water extremely efficiently every time. Just add water, flick a switch, then it’ll click off when it’s done. Probably the easiest thing in the world and uses the least amount of energy. Plus depending on your glassware/vessel, you run a risk of the glass breaking when you microwave it. I’m not sure how likely it is, but I know it’s a possibility.

      Not trying to convince you to switch, just pointing out the reasons for using a kettle. Do whatever works for you.

      Interesting. I use mine almost exclusively for reheating leftovers and melting butter, using it perhaps up to four minutes a day.

      I know it’s usually not an issue without a really smooth container, but I’d be too afraid of superheated water to boil it in the microwave.

        Back when I made coffee using water boiled the microwave I’m pretty sure this happened to me a few times, mainly when I’d boil the water, let it sit because I got distracted, and boil it again. I never really noticed in the moment, until I opened the microwave and the entire thing was drenched inside. Fortunately it exploded inside, not outside.

    I’ve never seen a “K” written like this. A “V” with an extra line. It’s difficult to read. Even though I knew it was supposed to be “kettle”, I kept seeing “vettle” or “wettle” or “mettle.”

    “That’s most of all efficient in our kettle!”

    Sorry, is this grammatically correct? Shouldn’t this be “That’s the most efficient of all our kettle!”

    Also I want a thermally insulated pressure cooker that can run on both 240V grid and on a 48V solar panels and that lasts 50 years. Tired of living in this fucking stone age.

      It may be grammatically correct in whatever dialect of English the author speaks. As an American I would say it reads weird to me too though.

      I think the punchline would be better as, “That’s the most efficient way to cook it!”

        It’s grammatically correct in the dialect of German-guy-trying-to-translate-his-punchlines-English. I still refuse to use ai to translate my comics, so there may be an odd sentence here or there. Trying my best, as usual.

        Also, I thought it’d work in the sense of a pun. Like “that’s most of all a fish end in our kettle”, which doesn’t really work if you restructure the sentence too much.

    At work, I wondered why the coffee tasted funny first thing in the morning. Turns out somebody didn’t want to buy a teapot, so he was brewing green tea through the coffee maker in the evenings. Found little florettes in the filter basket. Bought my own Aeropress after that discovery.

    Is a kettle really more efficient than a microwave? I would have thought a microwave would be best since it directly heats the water

      A magnetron is usually only a bit above 50% efficiency when converting electricity to microwaves (according to Wikipedia, that is), so I had actually assumed the difference to be even bigger.

      Electric elements are actually pretty efficient. Usually the heat generated by an electric current is the inefficiency (as well as sound, radiation, and vibrations), but for a heating element you’re using that heat waste. It still can generate sound, radiation, and vibrations, so it’s not 100% efficient, but you can do well just sticking an element in the middle of the thing you want to heat, especially if it’s a fluid. If you don’t stick it in the middle, then you lose heat in all the directions away from the thing you’re trying to heat.

      Heat pipes are more efficient because the heat isn’t being generated but just moved. Natural gas (or fossil fuels) seems more efficient but is actually just cheaper, as it used energy that was stored a long time ago.

      Even induction burners still lose heat from the bottom of the pot into the induction burner itself, hence why they usually have cooling fans. And the reason why they are more efficient than radiative heat or those spiral elements is because they create the heat closer to the food using an electric current in the bottom of the pot/pan itself, though even the induction part has additional losses.

      Depends on whether you’re in a country that washes eggs before sale too get rid of the cloaca residue or one that keeps it on so eggs can be kept safely at room temperature. Unwashed eggs will have faeces on their shells, and you might not want to cook noodles in faeces.
