  • 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.


  • 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.



  • 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.


  • 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.

    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).



  • I’m an electrical engineer who designs commercial and Utility Scale PV systems (i.e. Multi acre solar power plants), though I’ve done a couple dozen residential systems as well.

    @evranch@lemmy.ca chimed in with some really good advice, but I wanted to add a few things.

    If I were to do my own system I’d go with micro inverters, enphase IQ8 most likely, as they can be setup to operate during a grid outage, either with a battery backup, or with a load balancing panel.

    Careful of the downfalls of going the DIY route, not sure how it is in your state, but in some states I’ve worked in you will forfeit incentives if you don’t use a qualified installer.

    Get familiar with your utilities net metering policies, if they don’t net meter power at or near retail rates then you’ll end up giving them your power for free/cheap whenever you overgenerate. Some utilities will also make it difficult if you’re not going through a qualified installer.

    Lastly, and this is coming from someone who understands the industry intimately, really take a look at the numbers and decide if this makes sense for you. Most residential solar will take 5-10 years to pay for itself (after incentives) and start to generate a profit. Compare that with the same sum invested in a general s&p500 index fund which would likely have doubled in value during that time.

    Ultimately I decided not to install solar on my home, despite the ability to 100% DIY the whole thing and get parts at steep discounts, and instead installed a backup generator and signed up with a local community solar array (which is not something that all states/utilities allow).

    Happy to answer any questions you may have!
