For the last day.
For the last day.
You sure about that?
You missed out bully, misogynist
WTF is a wifi company? Next up: how a cat5 company can protect your privacy??
Checked the mod log. Seems a bit harsh to delete your comment
Agreed, it is totally subjective. For me, 5 posts in quick succession, all linking to the same website, is spammy, and i will downvote it. Interesting technology, but one post with a link is enough for me. But i respect anyone’s right to disagree and upvote the posts.
It is technology, yes. It’s new, a bit niche, but i would be fine with a (cross) post explaining what it is. But there have been several posts from OP on this.
Stop spamming the technology community wit this stuff, keep it in amateur radio please
Still dead, and not on iOS App Store anymore
That rule is as rubbish as most headlines though
Time to send more Bradleys then.
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
I like that theory
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.
What seems to be the original study:
https://www.nature.com/articles/s41561-024-01480-8#Sec14
TLDR, they aren’t sure where the (small amounts) of oxygen comes from. And while the article is full of numbers, the section on measuring voltage from these lumps does not contain any. The raw data suggests (to me as a non expert) that the voltages measured are way too low for electrolysis of water (which requires >1.5V)
Electrolysis requires an electric current, so energy. What I don’t understand from this article is where that energy is coming from. Magnets have nothing to do with it, they don’t produce energy. Batteries do, and different metals in salt water may act as a battery, but then they get used up in the process.
Electrolysis I get. These never ending ‘batteries’ though ???
I’m not sure what you are getting at. Apple offer storage and offer to encrypt that storage. You think that should be illegal? What about Apple offering storage and I encrypt stuff myself before storing it? What about a self storage company where I hire a container and put my own padlock on it? Or the self storage company has a duplicate key, but then I store a locked safe in it? And even if you could get Apple to change their ways: what about Amazon cloud storage - a lot of companies and agencies would be very unhappy if Amazon could scan their data. CSAM is a problem. But abandoning all privacy and security is not the solution.
The article is a bit shitty. I’m sure exxon-mobile are lying about something and i do not want to defend them. But the article does not spell out what they said on this topic that was actually a lie, and goes on to state how much was actually recycled - plastic recycling is a complex topic, but the fact that not everything that can be recycled is actually recycled is hardly exxon’s fault
