  • it really is so true.

    you install linux on one machine, and then suddenly every other machine you own has linux on it, ssh, and you use shit like rsync to manage shit over the network. Before you know it you’re running a snapcast server to manage multiroom audio automatically configured into your smart home network. (i haven’t gotten this far yet, but it’s eventually going to happen lol)

    The pipeline is real.




  • not very much, especially during the winter, the best way to optimize panel production is by pointing it towards the sun most effectively, the farther north, or south, of the equator the less effective it is, the less directly it points towards the sun in general, the less power you make.

    It might still produce a decent amount of power overall, through a reasonable period of time, but it’s probably WELL below what you could be making with an optimized install, especially one with solar tracking, granted some solar power is still better than no solar power, so you do get tradeoffs at the end of the day.

    as another commenter said, there are solar power calculators out there, if you’re looking for rough figures, use them.




  • microgeneration purely in DC only really makes sense in stuff like campers and RV’s where you’re going to be using primarily nearby, low power consumption devices.

    AC is still better, plus modern switching technology while still fairly expensive, is considerably more efficient now. If you’re doing AC you also get a number of other benefits, notably, literally every existing appliance and device uses and works with AC voltages, the entire standard around electricity and home wiring is based on AC mains, all of the accessible hardware is also produced for AC mains, not that you can’t use it for something else, it’s just not intended for that.

    Certain appliances will use induction motors, and similar other tech (clocks for example, often use the frequency of the power grid to keep time) based directly on the AC sinewave. You could still run them on DC, it’s just significantly sillier. Plus transmission efficiency is a BIG loss in DC (even now with modern solid state switching components, it’s still just, not ideal), granted thats less of a problem on a micro grid scale, it’s still a concern and potential restriction, nothing beats the simplicity and reliability of a simple wire wound iron core transformer. There are a handful of other technical benefits, and drawbacks as well, but fairly minor.

    Having a dedicated DC supply side might be nice for a home environment, but the question is what do you standardize on? DC/DC voltage conversion is fairly efficient as it is already. Converting from AC/DC is incredibly easy and not particularly inefficient at lower power consumption, it’s more of a problem with higher draw devices. But you can easily get around that by using a higher voltage to convert down from.


  • a mix of both is good, there’s arguments for doing local co-generation. Where you essentially turn a community into it’s own power plant, and when you’re talking about things like micro inverters, the cost doesnt really change.

    Is it more efficient to do it at a utility grid scale? Yes, does that make it overall better? Not really, you still have to deal with grid inefficiencies, and maintenance, and well, you still have to deal with installations, so the cost isn’t that significant at the end of the day.

    Solar is one of very few renewable energy sources that you can actually locally build and maintain on a small scale, no sense in removing that utility from it, that’s part of the reason it’s so popular.







  • Its wild to watch society at large do this more and more often, from the outside, as a non corpo, algorithm driven social media user.

    ironically, i’ve sort of done this at a smaller scale among some of the communities im in, and you would not believe how stupid people are, even when you literally inform them to their face that you’re saying stupid shit for the purposes of saying stupid shit.

    rage bait is incredibly effective and there’s a reason everything using it goes so far. It’s innate to the human psyche.

    oh and by the way, for anybody who thinks this is like unethical or whatever, trust me, they LOVE eating it up. You would not believe how much shitpost you can do, before people realize that you might be shitposting.
