  • Solar panels are warrantied to 25 years to a certain performance level. They still work after that, but tend to have reduced performance.

    Geothermal systems have about the same 25 year expected lifetime. A lot will depend on if the owner keeps on top of maintenance or not. Given that most homeowners replace their water heaters in <10 years when it could have lasted 30 with good maintenance practices, it’s fair to say it’ll be closer to 25 years for a geothermal system when it could last 50.





  • Not OP, but I have my NAS and my office PC on 10Gbps SFP+ fiber, but that’s so I can have fast speeds to my NAS. Spinning platters are now the limiting factor on throughput, and it’ll be a while before SSDs come down in price enough for the kind of data hoarding volume I have. Roughly needs to be cut in half two more times, which is maybe closer than we all think.

    2.5Gbps switches are generally good enough for home use while using plain copper wires, but I use a lot of old enterprise hardware on my network. Enterprise hardware never heard of 2.5Gbps ethernet.

    Also, I found out my Unifi Edgerouter X maxed out at 500Mbps unless I shut off a lot of features. Upgraded to an OPNsense box. There’s probably a lot of home user routers that are similarly limited.




  • But that’s completely bullshit. Solar and wind are so fantastically cheap that finding a way to deal with the capacity factor isn’t a big deal.

    The new geothermal solutions are impressive and should open up a lot more possibilities, but don’t assume they’re being honest about any of it. They’ve advocated for nuclear for decades without actually building new nuclear plants.
