  • My claim is that fuel can be done right (read “clean”, more on that later), just how nuclear power can be done right. Will it be done right? Probably not.

    Also, clean does not mean no pollution, at least not in our world. Solar cells pollute, windmills pollute. Green energy in general pollutes quite a lot when compared to “no pollution at all”.

    No pollution seems unrealistic with current technologies and politics, so best we can do is attempt and limit our pollution to technologies which pollute less, or at least have the possibility of polluting less.

    Also, how did natural gas become a clean, green source of energy? (that’s a rethoric question, I know why, i just think it’s stupid.)


  • As far as I understand, the idea behind synthesized fuel is to bind CO2 to create the fuel, which theoretically should make it net neutral, if one ignores power consumption and chemical usage, as well as the CO2 probably not being sourced from the atmosphere.

    In other words, the technology should be sound enough, but it will most likely not be used for good, as per my first post.

    Then we come to the other issues I mentioned. The fuel should theoretically be CO2 neutral, but the plane does not fly where the factory is located. It flies some ~10km above surface, which means that we are pumping CO2 into the middle layers of the troposphere, which probably is bad idea.

    Edit: i realize that I formulated myself in a rather unlucky way in the first comment, whelp.


  • If done wrong? Then yes.

    Kinda like nuclear is one of the most clean power sources we have, until you put the raw waste into nothing but iron barrels and store them in a salt mine, and then wonder why the underground is becoming radioactive.

    Planes can be clean, it’s just a question of using synthesized fuel (edit: as in artificially created fuels, hydrogen-mixes, kerosene replacements, the stuff they use for rocket propellant, that kind of fuels), and not refined fuel (edit: from oil). Of course there are some other problems associated with jet planes, but fuel shouldn’t necessarily be one.





  • Your cleaning procedure should be fine, I do the same but by hand.

    I meant shaking the resin while it’s still in the bottle, before you pour it out into the reservoir of the resin printer. The resin can separate into it’s base components, giving bad prints, and might sometimes need a LOT of shaking to properly mix.

    One should also clean the bed/reservoir and “reshake” the resin at least every 24 hours if possible.


  • First off, remove supports while washing, and before curing.

    Regarding the cloudiness, you did properly shake the resin before usage, right? And yes, letting it dry entirely is rather important, so don’t skip on that part! ;)

    Regarding the layer shifts: your print settings are most likely sub optimal for your setup, you’ll need to readjust them, this can be very tedious, but if you are using a popular brand of resin in a popular brand of printer, then you should be able to find settings which worked for others.

    Regarding the layers: correct, it’s support failure! That, and perhaps a mix of bad settings for the chosen resin. Make sure that you have at least 1 heavy support for each large freehanging extremity, and finish it off with a LOT of smaller supports in the area. Especially if it’s a larger flat area!


  • That, and the reddit repost bots who sometimes mass post content from Reddit with no interaction on Lemmy.

    Now, having the same post being replicated on multiple subs was no rarity on Reddit, but they tended to use crossposting.

    I’ve found the current moderation tools to be enough to deal with the latter problem, but crossposting or linking posts would be a nice feature on Lemmy, even if I’m not sure how one would properly implement that on the fediverse. So yea…


  • We had this question before, so let’s get right back at it!

    There was a rather controversial happening at Reddit a few months ago, which caused a lot (in Lemmy terms) of users to check out Lemmy.

    Some of those users left rather soon, and some more keep dropping off regularly, as they can’t seem to adapt to Lemmy, or rather live without one or another feature or content from Reddit.

    Now to your question, what can we do better?

    Advertisement is of course one, but a large part of the users who left Lemmy we’re likely because of Lemmies unfinished state, so maturing Lemmy should be a top priority. “But properly maturing a social site requires an already existing user base” - and that’s exactly what we have right now, even if it’s dwindling.

    Other solutions might also spring from creating the better user experience, such as features to moderate properly, both on a moderator and user basis, and of course to provide sufficient high-quality content.

    We can of course try and forcefully promote Lemmy while promising rich lands and green fields, but I think that this is not the optimum path for Lemmy at this time, as we just might acquire the same bad reputation that vegetarians or Linux or a lot of other good initiatives suffered from.
