  • Lava lamps function by heating the wax/goop in the glass bottle to the point where it becomes liquid. So you can either use an old style light source that generates that heat (thats how they still work afaik) or you use an LED + a separate heat source.

    So total energy usage could only be reduced in the LED version by more efficiently transferring heat directly to the glass. The light bulb doesnt have direct contact so there is a layer of insulating air in between which means lots of heat goes to the room instead of the glass.

    A third idea would be a different wax/goop that is just always liquid, but that doesnt work well because the movement of the bubbles comes from the wax getting heated at the bottom, which makes it rise to the top where it cools down and then drops down again.








  • That’s like China setting up police stations in other countries to enforce Chinese censorship outside their borders.

    No it is exactly the opposite. Its like banning people that are known criminals from entering your country. Countries have laws(rules) and if someone breaks those rules, no matter where they were at the time, you can just say “No we dont want to see you here, you can go do that elsewhere but not here”.

    That happens all the time in the real world and is perfectly reasonable.

    What also happens in the real world tho is arrest/execution for crimes abroad. I would compare that to a complete lemmy wide ban where someone doesnt just get banned from one instance but every single one of them.

    But thats not whats happening here so i dont see a problem.
