Its not really teleportation you're murdering someone vaporizing their body and reassembling a copy somewhere else

Reply to comment by kushal1509 in Network states (countries that are cloud-first, land last) could see genuine traction in the next 5-10 years. A combination of remote work, crowdfunding, offgrid tech and more make it so that communities could find each other online and then purchase enough land to form a new country. Do you buy it? by istegerjf
I appreciate your long-view optimism.

Batteries cost a lot, require re-charging as they don't produce any energy and overall do not hold much capacity. Even Hydro has significantly higher energy output, but natural gas is used for most of the grid besides peak solar times.

FTL travel. No matter how you get there, warp or wormhole, you can then break causality which is not allowed. That leads to time travel or at least it's communication equivalent. It breaks my heart but it's true.

Agree. Old, half abandoned neighborhoods in places like Detroit, LA, and NY would be a great place to start. Most of those folks need more financial incentive than rural people.

In 20 years by this rate.
The event was ling and detailed.
Mineral extraction is the limiting factor at this point.
The new modular architecture of Tesla car assembly is a technological step for the car industry. The electric cars will beat any gasoline car with such a modular body.
The issue again are minerals for the batteries. Their processing needs investments into new mining operations and refineries.

Battery storage solves these problems as far as I know. You're welcome to explain why that's wrong.

That's contact water, dude. It's not supposed to be clean. they have those ponds to manage their water so it doesn't get released to the environment. They then take the water from the ponds (and TSFs) and run it through the treatment plant or some other form of treatment and then discharge it once it meets water quality guidelines.

tailings storage facilities (TSFs) are what you're thinking of. Settling ponds are those that are specifically designed to settle out suspended solids. TSFs will often contain a pond on them, but much of the impoundment area is beach (with varying degrees of water content). what I'm getting at, is that TSFs are more solid than water, while settling ponds are more water than solid (AFAIK). Mining terminology is weird.
And yes, in some cases tailings are reprocessed when technology catches up. It's kind of hard to do though.

I think us opining on this at this point in time would be like medieval scholars conjecturing about technology a millennia into their future.
My "headcanon" if it's an appropriate term here is that humans will eventually become post-humans and be a cat 5 civilization and we cannot even conceptualize what they might do. Who knows, maybe they'll tame time itself. Or maybe they already did and this is an ancestor simulation. Maybe if they're benevolent enough they'll even let us have an afterlife. Sky is the limit.
I mean, just think on the fact that a couple centuries ago the scientists of the day were concurring that mechanical flight was impossible or that women couldn't ride in a train without damaging their uteruses.

Solar doesn't create enough KVARs to power a grid sustainably. And forget about when, you know, night time.
Wind farms produce enough KVARs, but highly variable amounts of wind makes for an unreliable power plant.
I would love for us to be able to do all this, but it is not realistic.

Topics include therapeutic devices utilizing electricity, magnetism, color and sound frequencies. Rare documents concerning the Royal R.

Re Autism, there has been some suggestion that stimulating adult neurogenesis can improve autism.
Longjumping-Tie-7573 t1_jao0lg0 wrote
Define 'treatment' in a way that removes the possibility of doing *anything* to improve autism symptoms, please. We already know that dietary changes can lessen the symptoms for some, so you're already wrong on that point.

Frankly, medical technology is pretty much the LAST area I'd say something is going to be impossible; mate.

The only thing that we are completely sure is that we will never know everything. Technology wise, humans don’t really know the limit of what is possible or what not, but we only know of what we are capable of right now in our advancing but limited comprehension of things

One truly impossible thing is to answer this question. there is always a horizon behind a horizon we are simply moving borders of what we define as impossible. Defining anything as such is stupid for a simple reason - we don't know everything, if you don't even know what you don't know how can you say that sth is not possible, in 50 years today's impossible may be trivial, noone is able to tell

That’s good, like I said I have no clue about any metrics, but I do still feel like we could cut carbon emissions from manufacturing are not as looked upon as end product metrics

Even if you look at manufacturing emissions, EVs still have a lower overal carbon footprint than gas cars.

One thing that always gets me is carbon emissions in manufacturing. I’m not by any means against electric, but I feel like too many people look at the end product of an electric future but don’t look at the damage that can be done manufacturing it. I’m not against anything, and petrol cars have disadvantages in manufacturing too, but we should be trying to shift more focus on environmental factors and methods of production in literally anything

But when it comes to stabilising the grid, those disadvantages are irrelevant.
