  • There’s one more outlier though which is Electrochemical cell, like galvanic element or voltaic pile

    It was used around 1800 as a major electricity source, but I guess it quickly became uneconomical in 1866 or sth when the dynamo was invented.

    Edit: wait yes, it actually says this in the second paragraph of the linked article:

    The entire 19th-century electrical industry was powered by batteries related to Volta’s (e.g. the Daniell cell and Grove cell) until the advent of the dynamo (the electrical generator) in the 1870s.


  • So, I don’t know why you’re taking a stand for Uranium today. It used to be a good technology 30 years ago, but today it just doesn’t make any sense anymore.

    First factor is cost. Renewables (Solar + Wind especially) have really really gone down in cost (see this link and this link), and the population will favor the energy source that is cheaper in the long run.

    Secondly, the environmental impact of solar is really not that big. When we talk about how much CO2 solar produces, it’s mostly because that solar needs silicon and that needs energy to be purified. And that energy mostly comes from coal, gas or other non-renewables today. But guess what, as the solar revolution progresses, that emission goes down as well, so solar actually becomes more environmentally friendly over time.








  • I wonder whether it was the right decision to not federate with Threads.

    On the one hand, yes, they would have caused a lot of problematic content, but on the other hand, it would have meant a lot of new users, and that would have livened up the place a bit. I guess.

    Maybe we could do a switch in the user profile for Lemmy where it says “show Thread posts in All posts”. Or something.







  • In humans, there’s good things and there’s bad things. But most of it is actually in-between.

    If you take out everything bad, that satisfies you for the moment. And then you go on, looking for further progress. You take out the almost-bad, the somewhat-bad. In the end, it leaves only the good. But that is not enough for a human to live on.

    Constant surveillance leads to burnout and extremely high stress-levels.
