    1. You can delete and edit comments on lemmy. But that doesn’t mean all severs or users will honour that request. Same is true for reddit, hence why it is possible to see deleted reddit comments on 3rd party websites. (And deleted tweets, etc. on other sites.)
    2. People post on lemmy for the purpose of sharing thoughts and ideas with the world. If your stuff is private: don’t post it! This is true for all social media. Also note, lemmy doesn’t ask for your phone number or other unrelated personal information.


  • It will outlast bs. Mastodon has been around for many years now. It already outlasted Google+, which was bigger and had more funding. And since it has a broad base of support it’s unlikely that it will all just fall apart. Unlike the commercial social networks, no single person can pull the plug the fediverse. (Lemmy is younger, but it also seems very strong right now. I just hope lemmy still gets some exposure on the outside now that the major drama at reddit has died down.)






  • The cost of constructing and decommissioning power plants is important for sure; but it has nothing to do with energy density - which is what we were talking about before. It’s true that building solar panels takes energy and resources, and the panels don’t last indefinitely. So there is a lifecycle cost to using them. But the same is true for all forms of power generation.

    A common way to compare these costs is to look at the ‘payback time’ of each form of power generation. The payback time is the amount of time it would take for the power plant to produce enough energy to pay back the lifecycle costs required to build, operate, and decommission that type of plant. It’s basically how long it takes for the construction to have been ‘worth it’.

    In terms of payback time, wind power is by far the best; typically taking less than 1 year to pay itself off. Solar is pretty good too, but is highly dependent on where it is used. And nuclear… is not good on this measure. It takes decades for a nuclear power plant to pay itself off, because the plants are very expensive to build and decommission.

    Obviously there are other things to consider in terms of the strengths and weaknesses of different forms of power generation. But you’ve been talking about the cost of materials and construction as though it is a weakness of renewables, and it really really isn’t. That’s in fact one of their strengths, and a major weakness of nuclear. Its strange that you say nuclear is ‘insanity powerful for its cost’, because its cost is the greatest weakness of nuclear power. Its much cleaner than coal, but much more expensive, even though it uses so little fuel. And it is not cleaner than solar or wind, but it is still more expensive.

    Your point about land usage is a stronger point in favour of nuclear power… except that depending on what country you are talking about, that could easily swing the other way. Solar and wind do take up more space than nuclear, that’s for sure. But nuclear requires certain geological conditions for the safe operation of the plant, and the storage of waste. So depending on where you live, finding unused land suitable for renewables can be much easier than finding a suitable location for a nuclear power plant and waste containment facility.




  • The receipts for food aren’t so that you can return it. They are for expenses record keeping. For example, some jobs have a food allowance; or special tax concessions for food bought while working. But to get those benefits you need to have evidence that you bought the food.


  • What are you trying to say here? Are we still talking about fuel types here?

    Again, let me point out that solar power does not consume any fuel. The materials used to construct the solar panels are not having any power extracted from them. And secondly, nuclear power plants require construction materials too. … So I really don’t know what kind of comparison you are asking for here.
