Nuclear energy is more expensive than renewables, CSIRO report finds
  • Reducing dependence on their aging expensive nuclear power infrastructure has been a campaign promise of every French president for the last decade. Switzerland just voted via referendum to shutter their nuclear fleet, Germany has phased out nukes almost entirely.

    The reality of it is: They're expensive. They generate waste which could theoretically be reused or even locked away in underground vaults, but it's frequently just stored on site in reality. And whether the danger is real or perceived, no one wants to live next to a nuke, because if things go wrong, they go very wrong.

    Don't get me wrong, I would love to see nukes make a comeback, I think they're a valuable part of the energy mix. I actually know a guy in crypto who is trying to set up financially strained nuclear plants with on-site crypto miners to help them gain back some of that lost revenue from paying people to take power during light load periods. Which I think is a fantastic use case and a great way to make Bitcoin less environmentally destructive. There are other dispatchable loads that could fill the same niche (water desalinization, green hydrogen production).

    But the unfortunate reality is that nuclear plants are dying right now, and unless something big changes they're going to be driven out of existence by wind and solar.

    Nuclear energy is more expensive than renewables, CSIRO report finds
  • There are literally countries that went all in on nuclear power (france and switzerland come to mind), that now regret that play and are trying to transition away from them. Not for safety reasons, just because they are extremely expensive to operate and they become a money pit when renewables eat away at the base load that they were built to supply. You have nuclear plants paying people to take their power during the afternoons because they cant shut down quickly when the sun comes out.

    What's the most absurd thing you've seen someone refuse to do because of toxic masculinity?
  • Folks, we are witnessing toxic masculinity live in this thread, look at the way this toxic male masterfully injects his internalized misogyny into a comment that sounds reasonable at first but quickly devolves into more gender stereotypes, portrayals of woman as unreasonable, impractical, and irrational. Look at how he tacitly emasculates any man who likes to cook for the joy of cooking or clean things beyond a bare minimum. What a rare opportunity to witness the toxic male engaging in such iconic behavior, while unaware of it's surroundings.

    A Train Took His Legs and Career. His Employers at the Railroad Put the Blame on Him.
  • This is wild to me, not because the company acted like this, that was to be expected, but what they were arguing over: whether the guy who got his legs chopped off deserved workmans comp.

    How is that even a question, even if he made some mistake or ignored some rule, the man got his legs chopped off on the job, he should get workmans comp regardless. Accidents happen no matter how safe you make an industrial environment, rules are often made to be impossible to fully follow, you shouldn't have to prove the company was at fault to be made whole for getting injured on the job.

    I like big phones and I cannot lie (22000mah Tank)
  • Electrical engineer here. I love extra large batteries in my phones, kept my LG v20 way longer than I would have otherwise just because I didn't want to give up my extended battery. If you're seeing premature battery failure it's likely either poor quality battery cells, which wouldn't be unexpected in cheap offbrand batteries, or you're shortening the batteries lifespan with fast chargers and discharging to 0% frequently.

    what are some of the best purchases you've made ?
  • I've gotta chime in here with an opposing viewpoint. I got all laser lasik and while it mostly corrected my myopia (went from -5 to -0.5 sph), it gave me really bad astigmatism, to the point where night driving is much more dangerous for me. Glasses were a pain in the ass but at least they made things crystal clear. Post surgery everything except bright sunlight now has an annoying halo. I'm 3 years post surgery btw, and went back under the laser twice to try to get it corrected.

    Price of solar dropped 89% in ten years
  • There's a lot more nuance to this than most people will admit.

    Net metering is 100% unsustainable, when renewables become a big enough chunk of the grid generation mix, they often generate when no one needs the power. Forcing the grid to accept that power and even pay the homeowner a premium for it is a perverse incentive. Effectively what it does is allow solar array owners to avoid paying to maintain a grid they still use, and since the rich trend to go solar first, the poor are left holding the bag to maintain the grid for everyone.

  • Just pointing out that the grid is paid for by your electric bill, roughly half of what you pay is for delivery (paying to maintain the equipment needed to deliver you that energy), the other half is for supply (paying the power plant that generated the energy). So even if you and all your neighbors are energy independent you'll still be on the hook for at least half your bill, or they'll have to recoup it in taxes or something.

    Not saying that's a bad thing, just clarifying a common misconception that going solar should not mean you eliminate your electric bill. In fact many places where solar does offset 100% of your electric bill are ending up with the rich owning solar and the poor paying to maintain the grid for them.

  • Yes and no, the progress of solar array technology continues unabated, with multiple areas of research that are beginning to reach commercial applications. Module conversion efficiencies now are in the 20% range, but heterojunction cells, or Gallium Arsenide, or Perovskites, or any number of other possible advancements could easily put efficiencies up into the 30% range.

    That being said, the price of the solar modules themselves has already shunk to a small piece of the cost to build a solar array, with the bulk of the costs now being the support structures, wiring, electrical equipment, labor, development, etc. And those costs aren't going to decline, they'd still be there even if the solar panels themselves were free, so they effectively set a floor to the cost reductions we're seeing.

    *Permanently Deleted*
  • As others have commented, the open source home assistant project can take voice commands and perform smart home functions like turning lights on and off, reading off the forecast, taking down notes, etc etc. But it does have limits, you will have to script any kind of complex commands, like pulling headlines from an RSS feed, or playing spotify playlists, or really anything that requires fetching info from an API, it won't do those kinds of things out of the box.

    The other factor which others have called out is that it doesn't currently handle wake word functionality, though that's been on their road map this year and the Oct update might fix that. That being said, running a dedicated wake word app to fill in that gap is very much possible. See my thread here for more info: https://community.home-assistant.io/t/setting-up-a-100-local-smart-speaker-on-an-android-tablet-using-tasker-and-snowboy-to-handle-wake-word-detection/611435

    Phones should have FM radio again
  • Same, including an IR led is such a simple thing, why did this ever go away. Though I'm pretty sure most Chinese phones still have them, Xiaomi phones do for sure

  • I actually meant to reply to your comment but replied to the main thread by mistake, I had the same frustrations with modern phones losing features, and even fairphone dropping the 3.5mm jack was a wtf decision to me. See my comment on the ulephone 18t, it had virutally everything I wanted in a phone.

    Phones should have FM radio again
  • I'm going to chime in here to plug the ulefone power armor 18t I just got. I was pretty nervous to get a chinese phone as I've only had samsung and lg phones before, but this thing legit blows me away. Not only does it fully support every band that my carrier uses (rare even for phones made for the US market), but it has:

    • Replaceable battery that lasts 3+ days between recharges

    • Extremely rugged, IP69 waterproof and designed for underwater photography (physical shutter button and diving camera app)

    • 3.5mm jack, sd card slot, FM radio (with built in antenna - no headphones need to be plugged in), and an RGB notification led

    • Dimensity 900 chipset that beats a lot of the snapdragon chips on the market.

    • 12 fucking GB of RAM... yes, 12...

    • Wifi 6(ax)

    • Wireless charging and reverse charging

    • A fucking 60x magnification microscope? (Why???)

    • A FLIR thermal camera (Just because, why the fuck not)

    • Runs mostly bloat free stock android

    All that for under $600 (on aliexpress)

    The only thing it's missing is an IR blaster, otherwise this is the best phone I've ever had, bar none. It is a chonky beast though, be warned.

    This has really changed my view on Chinese electronics, especially at a time when phones for the western world are losing features and functionality all the time (including stuff from South Korean). Turns out capitalism isn't that great for innovation!

  • Because color is photons in a narrow range of wavelengths/energies visible to the human eye. Atoms have electrons that can emit and absorb photons under certain circumstances, but don't have any intrinsic color themselves.

    Color charge is a property of quarks thats trinary in nature, and is usually described in terms of red, green, and blue, since color is a useful analogy to how it functions. Despite the name, colored light and color charge are not actually related outside of the analogy.

    Creating your own locally processed hotword / wake word for home assistant assist commands
  • Interesting, can I ask a couple questions about that setup? How did you go about connecting all the pieces? Is it all handled locally? What hardware are you running it on? Do you have any good resources/tutorials you followed?

    0
  • While I eagerly await a built in wake word function, I decided to see what other options are out there and started looking into open source hotword detection projects, and found snowboy. Combining a snowboy plugin with tasker and an android tablet connected all the dots to run local wake word detection that drops seamlessly into the assist service.

    The only downside is that recognition for custom phrases is fairly limited (custom wake words are based on only 3 audio samples from the intended speaker), though it seems possible to use them, maybe even to setup different access per speaker, but I haven't gone down that path yet.

    Thankfully there is a small selection of "universal" built in wake words including:

    Hey/Ok Google

    Alexa

    Jarvis

    Computer

    Snowboy

    Smart Mirror

    and a few other oddball ones that can be found here: https://github.com/Kitt-AI/snowboy/tree/master/resources/models

    In short, using any android device (an old phone or tablet), install "Tasker" and "HotwordPlugin" which uses snowboy for the local wake word detection. Assuming you have the assist pipeline setup already and the home assistant app installed, have Tasker call the HA apps assist service whenever HotworkPlugin detects the wake word and triggers the routine. Set it to launch a new assist service with every trigger so it will take consecutive commands.

    Depending on how the wake word functionality is implemented in HA eventually this may be just a temporary solution, but it's working well enough for the moment.

    Tasker: https://play.google.com/store/apps/details?id=net.dinglisch.android.taskerm (It's a paid app, but well worth it considering what you get for $3.50)

    HotwordPlugin: https://play.google.com/store/apps/details?id=nl.jolanrensen.hotwordPlugin (there is an ad supported free version as well)

    Camera suggestions
  • I have foscam cameras and have been pretty happy with them. Regardless of the brand, make sure you firewall them from the internet or they will phone home.

    Reason I went with foscam was because at the time they were the only brand with an outdoor PoE camera that had a spotlight, 2-way audio, PIR, and ONVIF support. Which was what I wanted for an entryway camera. They've since discontinued that "SPC" model, so if I had to do it over again I would be just as likely to pick reolink (had shitty luck with amcrest).
