  • If your interest is in useful prints, I would highly recommend learning FreeCAD and just making your own to solve your own problems.

    Nothing beats the feeling of trying to do something, wishing some tool exists to simplify the process, visualizing what that tool would look like in your own head, designing it yourself, and then watching it (a thing that, as far as you know, has never existed before) get printed into existence for the first time ever.

    And then realizing that your design has some flaws and iterating over multiple versions as you make improvements. 😉

    There are lots of excellent FreeCAD tutorial videos online targeting 3D printing.






  • Well, then any mediocre journalist would be asking the obvious next question, “What in the hell were the authorities doing about it for those months?” That would probably have been a good story.

    “If it’s been going on nightly for months, did you report it to anyone?” is an obvious question that people would want to know and the reporter should be asking, along with follow up questions depending on the answer.

    That’s the problem with most modern journalists. They’re not doing anything remotely akin to investigative journalism. They’re just doing ask softball questions and regurgitate the answer journalism.






  • My first thought was, why is Canada allowing these trees to get cut down in the first place. Answer is at the very end of the article.

    Drax said the “low-grade” wood used to make biomass pellets had typically been rejected by commercial sawmills and either sold to the biomass industry as waste wood or burned to prevent wildfires. A spokesperson said it was “far better to use [waste wood] to generate renewable electricity rather than leaving it to burn”.

    The rules that allow companies in the forestry industry to disregard old growth as commercial waste are part of the problem, Hansen said.

    “Even exceptionally old trees can rot in the middle, which is one of their features that makes them so important for wildlife, but could mean the tree is called defective by the logging industry. This could mean that the tree is dismissed as waste wood. But a tree standing up in a forest is not waste,” she said.

    So, the law has a gaping loophole that allows the logging industry to cut pretty much everything down.






  • No. My memory is that the English language article was a bit unclear on the details and had several indications that the author didn’t actually understand the technology, but someone said a Japanese language article did a better job of explaining it.

    Brine and fresh water doesn’t make any sense, because you’re spending energy to create fresh water with the brine as the waste. Just turning around and recombining it to make evergy again is stupid. You can’t even get back as much energy as you used to make the fresh water.

    But, spending the energy to create the fresh water, letting people use that water as normal, collecting their waste water as normal, treating the waste water as normal, and then, instead of just dumping the treated waste water into the sea, recombining it with the brine to make energy makes a ton of sense.
