  • There arn’t really a lot of fossile fuel plants that are decomissioned before the end of their lifespan, so this is more of an hypothetical solution for maybe sometimes in the future, all the while we continue burning fossile fuels. So basically it is an distraction from doing what is needed now.

    And once a fossile fuel plant reaches the end of its lifespan the only usable things that are still there and can be reused is the electricity network connection. So those sites are good locations for cheap grid level battery storage (and maybe novel geothermal), but not small nuclear reactors that still need turbines and cooling towers etc.


















  • Nice to hear that they started operations now.

    I found this bit interesting:

    The Geretsried project will ultimately provide, in annual terms, 8.2 megawatts of electricity to the grid or about 64 megawatts of heating to the nearby town.

    Emphasis mine… so I would guess they focus on electricity production during the summer months?

    Such a close loop system has a bit of a low-grade waste heat problem during summer months though, even when using it to produce electricity. I guess we will see more heated public outdoor swimming pools again if this technology takes off.



  • If someone is offering a public wifi, there is a reasonable expectation that other people sitting in the same cafe for example can’t listen in on what you are doing on your device. As older wifi encyption standards are easily compromised, this requires enforcing a semi-recent wifi-standard. You can of course make your own judgement in your own home, but in a public space it is different.

    As for SSL certificates… this isn’t only a captive portal issue. If your device has such outdated root certificates that you run into issues already at the captive portal, you will have also issues with each and every website that uses https. Root certificates are only cycled out of use for good reasons, such as them becoming compromised, so by using an super old root certificate on your device you are wide open to MITM attacks on supposedly secure connections.
