  • It’s not just the internet. For example, students are handing in essays straight from ChatGPT. Uni scanners flag it and the students may fail. But there is no good evidence either side, the uni side detection is unreliable (and unlikely to improve on false positives, or negatives for that matter) and it’s hard for the student to prove they did not use an LLM. Job seekers send in LLM generated letters. Consultants probably give LLM based reports to clients. We’re doomed.

    The reason I questioned the literal battery theory / electrolysis is based on this quote from the BBC article The scientists worked out that the metal nodules are able to make oxygen precisely because they act like batteries. I have since found the original research paper (i linked it elsewhere in this post) which suggests the authors did not actually say that and aren’t sure of the exact mechanism. Your ‘voltage potential grabbing polar ends’ is not one on the known methods of splitting water into oxygen and hydrogen (see wikipedia, which all require electricity, light, radiation or extreme heat. None of which seem to apply here, and the paper also does not mention hydrogen being produced. So maybe there isn’t water being split here by these nodules



  • Taking a test lol no, way too old for that. But while these lumps of metal in sea water may generate some electricity, I can’t see them magically lining up in series like in a 9V battery, and below a certain voltage (1.5) there is no electrolysis - not even a little bit. But I have since found the original article and raw data, and it seems the people that wrote it don’t know either exactly how this oxygen is created.
