Scientists have found a rapid way of producing magnesite, a mineral which stores carbon dioxide. If this can be developed to an industrial scale, it opens the door to removing CO2 from the atmosphere for long-term storage, thus countering the global warming effect of atmospheric CO2.

So scientists have found a way to do what billions of pieces of vegetation do worldwide every day. Also, this assumes that CO2 causes global warming. Much better if the scientists had developed ways to remove real pollutants that currently affect air and water. Problems like so many tributaries where a sign advises people to eat no more than two fish per month caught there, and eat none at all if pregnant.

These and other ideas in geo-engineering can make sense, unlike transferring $$$ to backwards kleptocracies in the southern hemisphere.

And beamed solar power via microwave from geo.

Of course, we'll need Lunar ISRU (something we should already do to for both exploration and national defense, will give us the ability to refuel and maintain Geosynchronous Sats, and build huge Comm Sats). Ridiculous that people talk a Martian trip before we've even tested ISRU concepts on a celestial body and practiced long term habitation on a celestial object mere days away, where a "life boat" can be maintained and evacuation/rescue can happen in hours rather than years.

And then a mass driver, since once we scale power in space it will make economic sense.

The government will have to finance these projects in the beginning, get a basic infrastructure going, then private companies can take over and their taxes will more than make up the initial investment, not to mention the ability to completely switch to a permanent and uninterruptable power supply.

And beamed solar power via microwave from geo.

That actually will heat the Earth, as you are bringing in energy that would not be on Earth otherwise. Nothing significant, though.

Dude. Dude.

Evan, you cannot know this. The atmospherics, chemistry, and related dynamics are too complex. All you can do is be a disciple of whatever sect of AGW you chose. Answer this, water vapor is said by these same climate scientists to be a more potent greenhouse gas than CO2. But burning any hydrocarbon produces not just the CO2, but creates water vapor as well. So why no talk about a "Hydro footprint." Why just panic about carbon?

Huuuu??
I thought capturing carbon is to allow burning oil and transferring $$$ to countries like Saudi Arabia (which may be a backward kleptocracy but is up there in the northern hemisphere).

HeadSet says

So why no talk about a "Hydro footprint." Why just panic about carbon?

Because when there is too much "water vapor", it just rains. This happens frequently.

I thought capturing carbon is to allow burning oil

If those magnesite bricks can capture carbon, why not just burn those bricks? I presume the bricks do not store gaseous CO2, but take the carbon from the molecule somehow.

Dude. Dude.

Also assumes we want a colder planet instead of a warmer one.

If I had to choose, I would take a warmer planet any day of the week.

We may need to end up burning those magnesite bricks if the sun activity declines.

Water vapor is the MOST potent greenhouse gas. Not really in debate. There is obviously always water vapor in the air. The focus of water vapor is it's amplifying effects from non-condensable gases raising temperatures.

From the American chemical society:

The greenhouse effect that has maintained the Earth’s temperature at a level warm enough for human civilization to develop over the past several millennia is controlled by non-condensable gases, mainly carbon dioxide, CO2, with smaller contributions from methane, CH4, nitrous oxide, N2O, and ozone, O3. Since the middle of the 20th century, small amounts of man-made gases, mostly chlorine- and fluorine-containing solvents and refrigerants, have been added to the mix. Because these gases are not condensable at atmospheric temperatures and pressures, the atmosphere can pack in much more of these gases . Thus, CO2 (as well as CH4, N2O, and O3) has been building up in the atmosphere since the Industrial Revolution when we began burning large amounts of fossil fuel.

If there had been no increase in the amounts of non-condensable greenhouse gases, the amount of water vapor in the atmosphere would not have changed with all other variables remaining the same. The addition of the non-condensable gases causes the temperature to increase and this leads to an increase in water vapor that further increases the temperature. This is an example of a positive feedback effect. The warming due to increasing non-condensable gases causes more water vapor to enter the atmosphere, which adds to the effect of the non-condensables.

Actually I'd prefer if the planet stayed roughly the same temperature, instead of getting steadily hotter..

Is that a word?

No. Capturing carbon would be, for example, capturing the Persian Gulf and taking the oil. I seem to recall a recent candidate for POTUS who said of certain countries in that region, "We take the oil." If KSA had the guns and we had something they wanted, they would simply take it and kill us, as per Islam. Do unto others as they would do unto you.

Geo-engineering is about managing the climate. CO2 capture is one proposal to manage the climate.

Whether you choose to burn coal, gas, oil, or nothing at all is an energy choice. These are different choices on different menus.

I wish the country knew that Light Water Reactors are not the end all of nuclear power.

Are you advocating taking Saudis oil? Or burning coal?

This thread is about climate change and geo-engineering.

The fact is co2 is plant food that has caused a spurt of vegetation growth worldwide.

Major Breakthrough Could “Turn Back The Emissions Clock”

Meeting the Paris Agreement target of limiting global climate change to a maximum of just 2°C of warming will be no easy task. As the global population and middle class continue to expand rapidly, so too does our demand for energy and therefore our emissions as well. In order to nip climate change in the bud, a multi-faceted approach is vital. As a global community we must not only plant more trees, reduce emissions, and turn toward renewable resources instead of traditional fossil fuels, we must also research ways to undo some of the damage that has already been done and clean up our ozone layer however we can.

Now, scientists from the RMIT University in Melbourne, Australia have published findings that show a scientific breakthrough that has the potential to be able to pull carbon dioxide, the most notorious of all greenhouse gases, directly out of the air by converting into a solid carbon at room temperature. What’s more, this revolutionary process is all done with a minimal amount of energy consumption. While this new technology has massive potential and gives new hope to the endeavor of tackling climate change, making it work on a large scale will be challenging, to say the least.

Researchers have discovered several solid metal catalysts over the last few years that have the ability to convert carbon dioxide into solid carbon, but the distinction between these earlier discoveries and this newest breakthrough is that those catalysts required high temperatures--above 600°C--to function. Producing these kinds of temperatures comes with a lot of drawbacks, not the least of which are energy and money. These earlier catalysts had other negative attributes as well, becoming less powerful the more carbon dioxide that they converted into solid carbon, making them unsustainable and hard to work with.

It was precisely these challenges that caused Dorna Esrafilzadeh and Torben Daeneke, chemists at Melbourne’s RMIT University to shift their focus to a new class of catalysts that are made from metal alloys that maintain a liquid state at room temperature. Scientific journal Nature Chemistry published the findings of one such catalyst back in 2017, a compound that consists of catalytically active palladium mixed with liquid gallium. This catalyst, to be clear, does not function with carbon dioxide, but allowed palladium to continue conversion of low-value hydrocarbons into higher value ones, from alkanes to alkenes, without slowing. The relevance of this breakthrough when it comes to greenhouse gases is that it inspired Esrafilzadeh, Daneneke and their team to look into whether a similar catalyst could possibly work for carbon dioxide--a breakthrough that would have amazing potential for battling climate change.

Now, the researchers have made the first steps of that breakthrough. The research is still in its early stages, and will require a lot more refining, but the team of scientists has already successfully converted CO2 into solid carbon. The process includes an energy-conducting alloy of gallium, indium, and tin that is liquid at room temperature, as well as a small amount of catalytically active cesium and water. A wire is then inserted into the liquid metal and pure carbon dioxide is piped in before a jolt of electricity is sent through the wire and into the mixture. At this point the carbon dioxide diffuses into the liquid metal mixture and is converted into solid carbon, making the venture a success up to this point.

While there is still much more research and refining to be done and the RMIT University team says that the exact mechanism of the reaction is not yet clear, the results show incredible promise. If the reaction could be tweaked and scaled up to convert carbon dioxide straight out of our air, it could have truly world-altering implications. One of the research leaders Torben Daeneke says, “While we can’t literally turn back time, turning carbon dioxide back into coal and burying it back in the ground is a bit like rewinding the emissions clock.”

"A Cheap Trick Enables Energy-Efficient Carbon Capture
Using lime to scrub carbon dioxide from power plant smokestacks could cut emissions efficiently and cheaply."

At the power plant I was involved with we injected powdered limestone, the consistency of talcum powder, into the combustion chamber to help reduce emissions.

The problem with this however it is extremely abrasive to any elbows in the piping which means constant maintenance/repair/replacement of certain sections.

Then again water, after passing through a control valve, can cause a similar problem, if enough oxygen bubbles are formed and an elbow in the piping is in extremely close proximity to the control valve.

Finally, yesterday the UK Guardian confirmed another conspiracy theory when it ran its incendiary headline, “Climate engineering off US coast could increase heatwaves in Europe, study finds.” Uh oh.

https://www.theguardian.com/environment/article/2024/jun/21/climate-engineering-off-us-coast-could-increase-heatwaves-in-europe-study-finds

The story tracked a study published just yesterday in the Journal Nature (Climate Change), titled “Diminished efficacy of regional marine cloud brightening in a warmer world - Nature Climate Change. The study’s researchers were thec same unlucky crew blasting some kind of salt into the air right off San Fransisco, before alarmed local officials got wind of the ‘experiment’ and pulled the plug. ...

The Guardian article also mentioned, offhand, that oh yeah, Australian scientists have also been using “marine cloud brightening strategies” for at least four years now, cooling the Great Barrier Reef to reduce coral bleaching.

But they would never ever do it near you.

The gist — try to follow the logic here — was the researchers said their “models” showed that weather modification in one part of the world might cool that part, but it could also heat up a different part of the world, like Europe, which let’s be honest, who cares.

But — now they were caught red-handed, or white-handed, whichever — the lead scientist is now suddenly calling for government regulation of weather modification, which until ten seconds ago was just a fake news conspiracy theory on TikTok...

It’s not chemtrails, dummy, it’s solar geoengineering. Which is totally different.

So, basically, the study admitted that scientists have learned how, in theory, to create a heat wave in Europe by spraying chemicals into the air in San Fransisco. Heat waves can cause wildfires, which can cause destabilization. What else did the scientists learn? What didn’t make it into the published study?

In the Guardian’s article, as in every other article following the unexpected disclosure of the San Fransisco project, salt-blinded journalists failed to ask the most important question that every single reader wants to know: Where else in the world are they testing weather modification technologies by spraying chemicals into the air?

Besides chemtrails and salt sprayers, what other kinds of ‘solar geoengineering’ are going on?

Finally, are they doing it right now, over Gainesville?

The Guardian informed us that the entire weather modification field is completely unregulated, so you can’t say it is illegal. Bill Gates, or Bill Johnson for that matter, or anybody, can rent a boat or plane and spray whatever they want into the skies, pursuing whatever reckless experiment they can dream up trying to score a massive government climate change contract.

How many teams are doing it right now?

Some states, like Tennessee, have started banning geoengineering experiments, causing corporate media reporters and social media bots to laugh like adderall-fueled hyenas about all the stupid hicks and their ridiculous chemtrail conspiracy theories.

Like this uproarious headline from the very same UK Guardian that is now calling for regulations, but way back two months ago:




Coincidentally — I’m just pointing this out for context, don’t cancel me — chemtrail-denying corporate media is owned by the very same oligarchs and billionaires who are probably funding most of the weather modification projects in hopes of earning multi-billion-dollar government contracts. A weird coincidence!

Public-private partnerships, and so forth.

On that note, the salty experiment where the weather-modifying scientists were unexpectedly nabbed was being run on the flight deck of a decommissioned aircraft carrier, the U.S.S. Hornet, docked in Alameda in San Francisco Bay.

In other words, to whatever extent, the geoengineering researchers were working with the U.S. military.

No corporate media reporter has yet made the military connection. But you can be 100% sure our geopolitical enemies noticed. And unlike reporters, our enemies have probably looked into who the researchers are, who funded them, and what other stuff they are working on.

In other words, the new study may be a limited hangout aimed at pacifying enemies about what we were getting up to on that aircraft carrier in San Fransisco. It’s too risky, so we’re shutting it down. Trust us.

And for the social media censors: I’m definitely not theorizing about any conspiracies. I’m not suggesting that the San Fransisco experiment was actually a military trial of a weather weapon that can be deployed from the decks of aircraft carriers or anything like that. What a ridiculous idea.
