  • I’ve been trying to figure out what kind of personal computing device would fit in these power envelope.

    I dunno if this is what I want, but I like the idea anyway. ESP32 is like 500mW class or so (very rough estimate because I don’t care to look it up right now lol). So you can get more than 24-hours of processing with 4x AA cells or 18650 Li-ion.

    I feel like there’s something ‘under’ the classic smartphone that might still be useful as a personal gadget. But alas, smartphones are an always in your pocket device today. Bluetooth keyboard + Phone would be a more practical note taking application.


    Maybe this same thing, but instead as a minimalistic SSH shell for computer IT tasks? I like the design of this things keyboard at least.



  • Alas, the most problematic part of the energy curve is the “Duck Curve”, of which only natural gas has been identified as a solution so far.

    The setting of the sun does not coincide with higher winds. The elevated winds are deep at night when everyone’s asleep but the grid is actually 1/2 power usage IIRC compared to daytime usage. Not really the 7pm period where solar grossly diminishes (sun is low enough that solar barely contributes anymore), but the day is hot enough that Air Conditioners run, and everyone is home doing laundry or other energy-costly tasks since they’re still awake.


  • But my net negative power usage from the grid means that I’m using less energy than I feed in when it isn’t shinning out.

    Grid scale batteries do not exist yet, outside of pumped hydro. And honestly, they might never exist (Sodium Batteries in 2 or 3 years are our best bet at grid-scale energy, but maybe that’s not good enough. We dont know because they don’t exist yet).

    So, it. Balances out

    No. If there’s no grid energy storage mechanism, then the power is wasted during the day, and the natural gas spins up at night.

    Apologies if you’re not aware that the grid isn’t a magical energy storage device. But… it isn’t. The tech for energy storage does not feasibly exist yet on any large scale.


    Wind is an option but only in windy areas and windy times

    So, it. Balances out. (And in the near future I’ll get a residential battery for night. Those are freaking expensive, though.)

    I wouldn’t bother. When battery storage tech becomes feasible, the utility companies will buy it for the whole grid. Residential batteries are just for those who are tricking themselves into thinking these things are feasible.

    The #1 “battery” is pumped Hydro right now. No joke. Running water up a hill with excess electricity absolutely works as an energy storage mechanism. The best battery techs will be exceptionally large systems (Pumped Hydro. Compressed Air, etc. etc.) that take advantage of these effects.

    Even “Wind” energy is actually an energy storage solution due to the massive momentum the wind turbine arms have. So unlike Solar, a lot of Wind plants self-regulate and self-store their energy.



  • Because I have solar pannels on my rooftop and my annual energy usage is net negative.

    That’s not how that works. Natural Gas plants turn on at night to supply your electricity usage at night.

    No solar panel is working at night.

    Shill harder.

    No you? You’re trying to pretend that solar power somehow is supplying energy to your nighttime car charges. Do you even know what the sun is or how solar panels work?

    Unless you live near a pumped-hydro station, you aren’t getting green energy at night. Your best bet is nuclear, but for some reason a bunch of asshole environmentalists have hampered our nuclear rollout leading to this unpleasant situation where we have to rely upon natural gas more.



  • Where I draw the line is environmentalist jackasses who are out there hating on the Prius (ACEEE’s greenest car of 2024), which would extend the climate crisis.

    You guys are fucking up the #1 car in today’s market for fixing climate issues. Because environmentalism isn’t actually about what’s best for the environment, its its own insane cult that doesn’t actually calculate out the full issues associated with EVs.

    Hint: EVs that charge overnight do not use solar power for charging. Think about that for a sec. Its all Nat. Gas in practice. Rerun the calculations and you’ll find that Prius burns fewer fossil fuels than most EVs for the typical American.


    So stop fucking around with useful cars (like the Prius) and turn your attention to dumbass vehicles like the Hummer EV (which is so big and heavy that it burns more fossil fuels than a damn Corolla or Civic). EVs aren’t the answer, they’ve already been corrupted by the corporations to have insane designs. You need to calculate every car on a car-by-car basis before making large scale environmental policies.

    And if you have dumbass policies (like “Advanced Clean Cars II”) purposefully leave out highly environentally-friendly vehicles like the Prius, well… guess what? You’re part of the problem, not part of the solution.









  • Newspapers were always partially advertisement driven.

    But I think everyone would agree with me that Newspapers were better when a substantial base of their $$$ came from their subscriber base.

    Nothing is absolute in the world of money. There’s always additional sources of money elsewhere. From this perspective, I think we can argue that purely advertisement-driven media is what is most dangerous. Search is an important part of modern digital media, so thinking of the economic realities of funding, and how those economic incentives shape the website and future business is important.

    Maybe it fails, but Kagi is trying something new. And that’s good enough as an experiment for me. I dunno, maybe I’ll revisit the idea in 5 years or so, that’s really not much money in the great scheme of things.

    At very least, Kagi now has a “Fediverse search”, and now that “search-lemmy” seems to have died, I need something like Kagi to more easily search Lemmy.world and other Fediverse locations. (Google ain’t so good at this yet).




  • The layoffs were known last week though.

    Sure, the news is finally talking about the layoffs, but people were locked out of their badges and complaining last week about this. So now its official today, but it was public knowledge last week when that price declined dramatically.

    So the employees were nominally on the books until today. Big woop. They stopped working a week ago and complained about it online. You can’t hide a mass of 10,000+ sad and angry employees talking shit about Tesla. The stock moved on that before the official layoff announcement today.


  • Zoom out about a week.

    Its fair to say that last week, TSLA was oversold and is now bouncing back from that. But the -55% profits and -$2.3ish Billion FCF are bad numbers.

    TSLA is down from $180, where it was just a few weeks ago. $140 prices this past week apparently was too low, but there’s no chance in hell that TSLA goes back up to pre-Q1 announcement numbers. Q1 2024 was awful. Declining sales around the world in all major areas: China, Europe, AND USA. They’re weak everywhere.
