Climate in the 21st Century

[cannabineer]

We are likely to have the answers to many of these questions before the century is out, how complex multicellular life arose and when. We are also most likely to have a census of biospheres in a sizable portion of the galaxy, if they exist. Snowballs in habitual zones should not be overlooked either, as earth was one for much of its history. Oxygen is what we are looking for, that carbon oxygen combo with water, oxygen means animal life, the way we understand animal life and things with enough energy to move and think. Nature has often had multiple starts on a problem; the eye evolved independently a half dozen different times and it might be the same for photosynthesis.

I'm more interested in biospheres and their frequency than about receiving radio signals from little green men, but speculation on them could lead to some useful insights. Once we have the capability to reliably detect biospheres several dozen lightyears out, we will know a lot more about the prospects of little green men by 2100.

Alas, knowledge of good and evil goes back to the garden of Eden myth, we will know whether some of us want to or not, the bite of the apple is mandatory in order to move on. Let's hope it's a sweet one!

Our example of one thus far indicates that when we reach a certain stage of technological development, we control our fertility to the point of self-destruction by self-indulgence! That and the large number of "virgin worlds" seems to preclude galactic empires, at least by future humans, maybe our robots will be more prolific if we make them horny enough, in their own particular way of course! Sex for yer average robot might include a 3D printer of some kind...

Take the fraction of the say 500 million years complex life that counts have been around, now modern man has only been around for 100,000 years or so, agrarian civilization 10,000 years for some and less for others. Modern technology starting with steam since around 1800 in a serious way, about 200 years. If biospheres are plentiful then there should be a lot of uninhabited ones and less of ones with even primitive civilizations. If biospheres are rare or we don't find any after a good look locally, then we don't need to worry about alien monsters arriving unannounced.

Extreme weather events will help to drive change to a green future, maybe it's too late, but we will still try. The technology and prices seem to be getting there at a rapid pace and a lot of money is being invested. That fucker slamming into southeast Asia will get them thinking green, so will a big one that cut's Florida in half like a sandbar. We only need to look at the geological record for evidence of such super storms in the past.

from me watching this area...this is the 6th or 7th Cat 5 in this area......these storms are getting bigger in less time from my estimations.....heck look at the Atlantic side and look how quick that storm turned into a Cat 5, what was it 3 or 4 days, semi organized in day 1 day 2 was a hurricane and then it grew from there....and this is just this year

My point is slightly different.

The night is silent because in the tall grass there are lions, and they listen.

I guess we should know if FTL travel is possible, even by warping space time by 2100 and if it's not possible, then any arrival would be unlikely, but the paucity of technological life in the galaxy should arouse some interest in any listeners. Getting here by fractional C ships would be very time and fuel intensive, then there is the radiation and cosmic dust along the way, lots of radiation by slamming into interstellar dust at relativistic speeds. If we ever get to the stars under such a scenario it will be with humanoid robots producing superhumans from DNA data once they arrive and set the conditions, conditions there will be known before departure.

Any aliens that can listen to us and get to us, can image us from a far, just as we will be able to image them as they appeared hundreds or thousands of years ago. Our radio bubble has barely gone 100 years and I love lucy would be playing on a kilometers wide space antenna 70 lightyears out. Maybe the Klingons are saying WTF!

One hypothesis with which I’ve been playing is that the interval during which a society is recognizable as what we think of as technological civilization is (on astronomical or biological timescales) extremely brief.

One possibility (explored by greats like Asimov and Clarke) is that young civilizations like ours tend to destroy themselves, often taking their planet or star with them and leaving little trace.

Another is embodied in the concept of the singularity, a change so profound that we cannot effectively model what’s after the transformative event. We might not recognize it while looking directly at it. Lotta cool fiction written around a variety of possible outcomes.

Using an analogy of the galaxy as a fishtank, it might have one of those sucker-mouthed fish who keep the glass from getting green. In that scenario we’re the algae.

A hunch I’ve entertained is that by some objective outside standard, we are presapient animals. The “adult” world may be as far beyond us as ours is to our pets.

Thoughts like these are idle fun.

Maybe idle fun, but I think they can inspire more serious inquires. All we need to do is project ahead a bit and assume our global civilization will be around for another century to come up with some scary prospects. We don't need aliens, the predators are already here, and it could end up as a race between genetically enhanced humans and AI to see who owns the future. Humans as they are now might be considered "wild" varieties, future magats!

Local and national policy will make a difference and when battery storage and solar become popular enough prosumers will have an increasing voice too. All your energy needs for house and transport, with the ability to offset energy costs significantly or completely should be attractive in the long run for many people. In this case grid scale battery storage makes the grid much more efficient and stable while allowing more use of wind and solar for generation. The idea is the gas turbine generators never have to come online or if they do, just in winter for periods of time to recharge the grid batteries when load exceeds renewable capacity.

Amendments Will Bring More Renewable Energy, Storage to the Grid

Appealing to a particular subset of drivers but will it be enough to drive sales and what does this say about Toyota drivers?

I've noticed that complimentary truck nuts has done wonders to keep F-150s on top of the sales charts here in Alberta but that's understandable considering their attitude on the road. I'd be road raging too if I could only grow a pair off my trailer hitch.

Are you catching the halo eclipse today? Peak here at 10:30 MT and already started.

Just took pics and it's barely showing this far north.

This Lithium Tech Can Drop Battery Prices by 50%!

8,367 views Oct 14, 2023

We have a huge Lithium problem, with skyrocketing demand, can we possibly secure enough supply? This is a question I've been thinking about, starting with where Lithium even comes from. If we want to see batteries in homes and cars, well, we'll need to figure this out. So I flew out to Austin Texas to meet with a company called EnergyX who says they have the answer.

It turns out most lithium is collected in brine pools, and only around 30% of the available Lithium is actually extracted. This process is wasteful, and takes months to years to complete. Its these sorts of reasons why Lithium prices have become so unstable and skyrockted to as high as $80,000 per ton! The reality is, we'll never have a $20,000 EV that's got great range, if we can't sort out these sorts of foundational challenges.

So how does it work, and what might it mean for the future of Lithium? Let's figure this out together!

Smaller, lighter lithium-sulfur battery lowers costs and improves recycling options

Researchers at Monash University have developed a new lithium-sulfur battery design with a nanoporous polymer-coated lithium foil anode that reduces the amount of lithium required in a single battery.

Professor Hill said the technology could make an immediate impact.

"The market for electric vehicles, drones and electronic devices is on a steep growth pattern and this research is commercially ready for manufacturing to support that growth. Producing more economical and environmentally sensitive battery options in Australia would be a great use of this technology, and we look forward to working with commercial partners to develop and manufacture this technology," he said.

Most people think of geothermal as providing continuous baseload power and shallow geothermal wells could well exhaust their potential quickly. But what if such plants were only used for intermittent loads, when the sun doesn't shine or the wind doesn't blow, or for brief periods in winter only? The dormant periods might be enough for them to regenerate their potential and then they could be used for a very long time. No need to go really deep, if it is just used like a gas turbine generator with renewables and batteries.

Perovskite solar panels are expected to hit the market soon with a big splash and are cheaper to produce than silicon and collect light of a different spectrum than silicon and can be used in tandem with them. They can be made into flexible panels and perhaps integrated into roofing shingles and tiles with a more traditional look than panels on the roof. We will have the cheap renewable power and await the cheaper better batteries which are well on the way and that will make it all work. I figure in 10 years we will have the batteries and the solar generation for many of our needs, including compact solar powered cars.
