  • Totally, and I think that’s why they thought it was worth a press release. In the article they go right to how they’re setting a new power density record with this design.

    Electric motors are just really power dense. The article says they managed a short term peak of 1,000 hp with that little flat 12.7kg motor and the continuous output could still be half that.

    Just the cooling must be crazy.

    Out of curiosity I looked up something comparable. It looks like high-performance integrated drive units that have other stuff like the single-speed gearbox, differential, and inverter are still only in the dozens of kg.


  • The voltage/hp comparison there doesn’t really fit.

    Power is in watts or horsepower. You multiply the torque with the RPM and a scaling factor to get power.

    A higher voltage system could probably be expected to produce more torque and power from the same size motor, but a lot depends on the design of the motor.

    Then to answer “how much torque though,” I haven’t looked into it but electric motors have a very nice torque curve across the RPM range. If a motor made all that power with low torque, then it must spin at super high RPM and need to be geared down.





  • I’m a couple years older and didn’t even get to start trying medications until my 40s.

    And sure enough, gifted student and high scores on standardized tests and IQ and stuff, right here. Looking back it can be pretty frustrating to see how much of my childhood was shaped by it, but it’s harder to blame the adults in my life the further back I go.

    What really frustrates me is that I went to a psych practice as an adult looking for some kind of help with my extremely stressful issues that I noticed exactly matched every description of ADHD I could find. There were questionnaires and a small battery of neuropsych type questions to evaluate things like short term memory and processing speed. I did well. It did not lead to a diagnosis.

    So yeah, when I am sitting in a room 1:1 with somebody and I am in performance anxiety hyperfocus mode, I can do good on some fucking word problems. And that meant I DON’T have ADHD? Thanks, fuckers.


  • Thanks for posting this, because I started getting bummed thinking about how much of a great resource the full reddit history would be to just have online, were that whole thing not ruined gut bad reasons by bad people.

    But then you reminded me about the good people.

    I found the helpers, Mr Rogers!


  • Ok bear with me here but we’re on Lemmy so I think I get in trouble if I don’t ask this…

    Have ya tried Linux on the old machines? If not, you can make a bootable USB of Linux Mint and play around with it without changing anything on your system. The UI is laid out like Windows.

    Nothing makes an old machine sing like installing Linux!


  • When I switched over my home desktop to Mint, it was a very short time before I looked at Windows and said “I’m too old for this shit.” I mean, the reason I am a Mint fan in the first place is that I am a FOSS loving nerd but with a family and pets and hobbies and a career and a middle aged energy level. The decades I’ve spent fixing Windows based PCs is enough for a lifetime, thx.

    I say consolidate old files you want to keep. Shuffle them between drives as necessary to be able to format everything. Go all ext4 on the drives you already have. (once you’re ready)

    This is the way.


  • I think these days the PC value argument is a lot more about longevity and versatility than price.

    Like in my case, I want to have an old fashioned LAN gaming setup in my house. I’ve already managed to find four PCs stored away, and they are all going to work great. Three are already set up and have linux installed and everything. So they cost a decent amount in their day, but now they’re kind of just free extras.



  • I agree with everything you’re saying.

    And unfortunately as a life-long resident of white suburban america, I know how comfortable life still is for so many people, and how the culture of “ignore that problem and we’ll be fine” continues to pay off for people with a little privilege in their life.


  • YES!

    It is not always easy to judge how much an activity will benefit you going by how much you want to do it beforehand. It is not always as simple as exercising and eating your vegetables either. Shit’s complex.

    I describe it like each of our brains has a long, detailed, and customized user manual – but we don’t get a copy. We can choose to attempt to reverse engineer that manual if we have the right motivation.


  • This reminds me of something I was commenting about yesterday.

    Focus on your immediate environment first, and make your little corner of the world better before you worry about saving the universe.

    And like you said, it is a habit and mindset thing. If you plant a tree in your yard or in your community, no it will not save the rain forest, but your mental health and physical health and living conditions will all be slightly better off than they were before it.

    If you start intentionally working in these positive actions that provide tiny incremental improvements, before you know it you may be feeling more than incrementally better.
