    The problem is that it can only be speculated how they work, because they have not published it. That is quite suspicious in my book.

    I personally would avoid reolink and use rtsp + frigate + ha, to have full control with known open source selfhosting solution.

    I understand that people like the easy setup, but if you already do selfhosting, it isn’t that big jump.

    Be careful with reolink, their P2P solution is pretty suspicious. No body really knows how it works and who it shares the data with.

    You can disable those features, but it will stop reolink app from working.

    They have never explained how the peer-2-peer network works, and it security and privacy is quite unknown.

    Reolink is Chinese, which doesn’t really help these concerns.

    Better to selfhost frigate and just rtsp cameras there.

    I am sorry guys, old man here, but 1997 was the best year for gaming:

    • Diablo
    • Fallout
    • Quake II
    • Ultima Online
    • Ages of Empires
    • Final Fantasy 7
    • Grand Turismo
    • Golden Eye 007
    • Starfox 64
    • Crash Bandicoot II
    • Tomb Raider II
    • PaRappa the Rapper

    How the hell do you beat that? Most of the games released yearly are sequels to these games.





  • Three things that should always be ran by government: healthcare, education and prisons.

    They must exist, and privately owned ones will always have wrong base incentive.

    With prisons especially, it is not the interest of private to rehabilitate, but to get people in prison loop. It just cannot work. It is just easy to sell to people because people want prison to be punishment facility.







  • Large scale three phase energy generation is always something rotating in sync with the grid. Easiest way to do that is to spin turbine+generator.

    All nuclear, coal, biomass power plants just heat water to 300-800°C and push it through turbine.

    The thing is that it is really quite robust, and there isn’t any other good solutions to it. They do have quite a lot of loss, but the cooled water after process (still over 100°C) can be used in other industries or district heating improving the efficiency.

    Hydropower just spin the turbine with water flow. Wind directly spins the turbine, which is good for efficiency. Solar panels are still quite inefficient, but because they just use space, they make lot of sense even with poorer efficiency.




  • Yes, and the basic principle of thermal batteries has been quite common here in Finland for some time.

    All Finnish cities have district heating networks, so there is some heating plant that generates heat, which is distributed to homes using water as medium. It is closed system where hot water goes in, colder water comes out, which is heated back up. This energy is used to heat the home and heat the cold usage water (faucet/shower etc)

    Because the network is lots of water, there is already quite a lot of energy storage in the heat grid itself, so itself works as a battery. In last five years almost all big networks have created water based thermal batteries. Those are 7-8 stories high insulated water containers. These make sense because you just start taking the already heated water from the container to the grid when ever you need.

    So the tech itself is quite standard here, just the medium of using sand is new. Sand brings you bit longer storage time, but adds bit of complexity to the process.
