Climate in the 21st Century

Yes but concrete.

I await developments too, but the closer they are to patents and commercialization the less they say. They have patents and two papers, one in nature the other in science behind them and investors too. It does look very promising though and scalable enough, a bit more efficiency would be nice, but that can be iteratively improved.

What I mean is that unless/until demonstrated otherwise, (even if the heating step is made green) concrete 1.0 is hard to beat for a cheap durable engineering material.

A rock in hand beats pie in the sky any time.

Ya tend to go with what ya got, like Tesla did using thousands of 18650 laptop batteries in EVs. There are several alternatives for concrete, and more are being developed, if push comes to shove, we can use carbon capture, but I don't think it will be required. Some traditional chemical processes might be done differently and be more useful with renewables. If renewable energy gets cheap, even for part of the year, then energy could be a key factor in the production of lots of things.

A Runaway Greenhouse Effect is Very Unlikely On Earth

Iirc the projected competing processes are not commercial.

The bigger question is where to put the CO2.
Deep-ocean injection is a no-go as marine ecologies are already taking an acidification hit.
Maybe pumping it into old petroleum domes. They should hold together for a century or two.

Possible????

Possible.

We are talking gigatons of carbon dioxide! It might work as a cold jet thruster like spaceX uses, simpler, safer and cheaper and does the job well enough.

It liquefies and solidifies at reasonable temps and thus increases its density and lowers its volume, in space it should be no problem to keep it solid at those temps, heat it up to use as a cold jet thruster or as reaction mass in an ion engine. I can see the advantages.

from reading that paper it is possible.....and it is wildly abundant both here and on Mars.......

Good point about mars, reaction mass for the trip home and for thrusters. Shit, harvest CO2 snow on the ground there!

More on future of food and climate change. Whey protein like body builders use is very expensive these days, it is one example of how these guys could make a buck. If this shit about fermented meat and other protein products comes to pass and follows the cost curves, then it might have some serious implications and the buffalo could roam the west once more! The people living and making a living there might have other ideas however and most of them are as red as fresh beef, and boy will they have a beef! It's not the migrants they need to worry about, it's technology and then they will have genuine grievances to add to their real and imagined ones.

Who knows what the future will bring, disaster for some and prosperity for others. Remember though, it is not just us rich folks that could be fed by this technology, a lot of poor hungry folks could benefit too. The high price of food and groceries makes lots of things feasible. If you have the market, LED lights and hydroponics could make you money growing fresh greens for restaurants and grocery stores, selling lettuce might be more profitable than selling pot. Solar panels can power the whole operation too and the energy would be free, same for growing protein in brewing vats. There might be other very high value crops an experienced pot grower might try in their controlled indoor environments and leverage their hydroponics experience.


Can Lab-Grown Dairy Give Us A Cow-Free Future? | Lab-Grown | Science Insider

Plant-based dairy alternatives have been around for decades. Now, one California company has figured out how to make a that's completely animal-free. But can this lab-grown alternative make a dent in the massive dairy industry?

Thinking about precision fermentation of protein and meat along with cost curves, how long before major food corporations adopt the technology and cut the farmer out altogether? Dairy farmers in places like Wisconsin would be freaking out as would much of rural America in a decade and there is a lot of grievance in rural America already. Meat, poultry and dairy production are big industries and entire regions might be wiped out. Crop prices could fall as they switch to plowing fields and growing crops. Change can happen fast when propelled by market and economic forces the transition takes about 15 years and these people have been at it for a while now and laid most of the groundwork. You wanna believe this could have major implications for politics in America and more states could have few inhabitants but 2 seats in the senate, with a big chip on their shoulders too. Even the few in Wyoming would have to move out if fermented beef became a thing and was cheap, right down to the migrants in the meat packing plants.

The more I look into this fermentation stuff the more I think about the political implications for America, if it should take off, scale and follow cost curves the environmental and political implication could be enormous and change could happen faster than we think. There will always be a market for "natural" and organic products, but if major food corporations with resources and products get into this look out. I remember when people were concerned about GMOs, but this takes it to a whole new level. I figure plants should be ok for now, except for genetic modification for disease resistance and yield, flavor too. I don't make the rules or the future, just call em as I see em and I see potential political trouble if the American Midwest and much of rural America is wiped out by technological change. It happened before and most people moved off the land and into cities when the big agricultural changes came at the beginning of the 20th century, now only a small fraction of the population actually grows our food, and it might be a lot less in 10 or 20 years.


Yali Bio Reveals Precision Fermentation Dairy Fat

Private company Yali Bio is making precision fermentation fat that is specifically geared towards use in alternative dairy products such as butter, cheese, and ice cream.

In this video we look at that announcement as well as an intro pitch to the company by CEO Yulin Lu.

Hope all the fine folks in Texas have their gensets ready as the polar vortex is headed their way. -36C here tonight and Saturday is supposed to be colder so we might break our old record of -38.1 set here Jan. 15 2020.

I've had a rotten cold or something all week and have to go to town tomorrow no matter what so I'll be wearing a mask to protect the townsfolk from my nasty germs.

This time of year really stretches out the differences in climate. Our '70's era house in Oregon is barely able to handle days in the low 20's F (-7 C) We are going through a stretch of that. I've set up some portable heaters in the weakest areas of my water supply for my peace of mind. But I don't have the clothes or living space to handle what you guys deal with each year. -20 F (-30) we are simply not prepared for long periods. of that. Maybe a spike down to that but not even a day of those temps and we'd be busting pipes all over the place.

Texas, on the other hand. They get both the long stretches' of heat and cold. . No wonder they are so cranky.

Hey now...lol...

Currently I am sitting at 31f with a 15mph wind out of the north, low tonight 21f.....tomorrow is gonna be pretty much the same, with the low in the teens

So far do good with ercot....

Speaking as one who grew up just south of San Francisco, the weather you describe sucks. Never mind that I'm putting up with similar here in Oregon. I think it sucks here too. My wife who was born and raised in Alaska is loving it though. But she's cranky too.

Oh it does suck...I've lived in texas all my life, and we've had artic fronts, these last few years they've been increasingly strong, 21 snow and ice, power company failed....this one temps 30's to teens for bout 3 days winds out of the north 15 to 20, keep our fingers crossed for the power company holds and then a roller coaster of temps throughout the week....I feel sorry for the people in Okey and north Texas right now...there temps are even lower.

My wife gets cranky to...js....has ur name changed yet....mine has twice today...lol

And I still gotta work tomorrow

Sitting at -35C all day here. The dog finally decided to sleep in the mud room where it's a cosy 5C but slept outside all night last night. Zero wind so that's real temps without any wind chill. House water froze up yesterday but all good today.

Nice not to have to go anywhere when it's like this.
