What will they do when they unearth a large monolith 😬
But seriously, it is hard to really grasp that something like cabin building was happening half a million years ago. I guess that river might have been following a different path then?
Sure, but do you remember what lithium batteries were like 20 years ago? I don't, not really at least, because they were all NiMH or some other tech. Why take a dump on a new tech that may prove useful? The article talks about this being a potential replacement for lithium, not yet ready, but it was briefly, and at the end.
they are constrained by physics to always be heavier and have less energy density than a lithium battery. Forever. No matter what they do.
So? There are many applications for batteries where size and weight are not primary considerations.
You know that lead acid battery in your car? Yeah, that’s a “water based battery”.
Cool, I am glad you know what water is. These batteries are not those. Irrelevant to the conversation.
I will never be a replacement for lithium. Ever. The article is almost as nonsense as the “research”.
What's your point? I choose to be optimistic about the potential this offers, rather than castigate it as worthless. This is how science works. It is not nonsense.
Maybe you don't like the mouthpiece, but it is just regurgitating information from a journal. You can find similar research reported in other journals. You clearly don't like it, but that doesn't make it bullshit.
Optimism and naivety are not too far apart. Often it is just from one's point of view.
I'm aware there are issues with science journals, but even ones ostensibly more trustworthy cover this type of battery more recently than 10 years ago. And being critical can be hard for anyone (such as me) who is objectively not a scientist and is not an expert in this field. I, and probably nearly all people here, can benefit from discourse in this setting. There is essentially nobody doing that tho.
The letter argues that the bill “would make our kids less safe, not more safe,” since the bill would grant state attorneys general the power to determine what content is “unsafe” for children....
I wrote my Democratic senators about this nearly a month ago, and they really doubled down on why they support it!
For the curious (fingers crossed for formatting):
Dear ********,
Thank you for reaching out to my office. Keeping in touch with my constituents is my greatest priority, and I appreciate the opportunity to engage with you on such an important topic.
As the world becomes increasingly interconnected through the Internet, it is important that Congress considers the effects of computer networks on individual freedoms and acts to protect individuals’ personal information. Children and teenagers today use the Internet to learn, express themselves, and stay connected, and we must do the utmost possible to protect minors’ personal information from being manipulated and exploited by companies looking to turn a profit, while ignoring the consequences. That’s why it’s critical that Congress acts urgently to create legislative guardrails that give users control over their personal information while holding Big Tech accountable for harm to our young people’s health.
That’s why I am proud to support two vital pieces of legislation to protect children online that were reintroduced in the Senate in May of 2023. The Kids Online Safety Act (KOSA), which I was proud to cosponsor, empowers kids and parents to take control over kids’ online experiences to better protect their health and well-being. The Children and Teens’ Online Privacy Protection Act updates online data privacy rules for the 21st century and ensures both children and teenagers are protected online. I also successfully fought to include amendments to both pieces of legislation to ensure that these increased protections extend to all children, regardless of the language they speak at home.
It is past time to pass comprehensive privacy legislation, and I am continuing to work with my colleagues to bring these vital bills to keep our kids safe to the Senate floor this Congress.
Once again, thank you for expressing your concerns on this important matter. I am humbled to serve ****** in the Senate, and I look forward to continuing to hear from you. I hope you will consider keeping in contact with me by subscribing to my newsletter here. If you are looking for assistance navigating a federal agency, or would like to speak to a member of my staff in ******, please visit my website here for more information.
I don't know who started the "facts don't care about your feelings" saying, but at this point it appears to be more like "feelings don't care about your facts."
Wilderness designation and spatial modification requires an act of Congress, perhaps a name change as well *this is addressed in the article. Congress must change the name.
Very fair! I had friends working in Australia for some time but never visited, my loss. It really sounded interesting and different.
Ya, possibly. I would think that earlier people, as observant as they were, were building swales long ago in Persia or North Africa. Or SW USA. Or Australia.
My work phone is one of these I think. The article doesn't really say what, if any implications exist from this radiation. How much electromagnetic radiation could a mobile phone possibly emit?
I don't understand all the people in this thread who seem to think it's not worth it. Here is a proposition, with some numbers.
"Can't be done"
Where is your idea then?

I agree, great photo! And I mean really, a photo of such an abstract place could perhaps be abstract photography after all.
In the last couple of years, I replaced all my lawn care equipment with battery powered and it has worked fantastically. I’m sure there will soon be other large batteries that need to be charged....
