US to build giant space vacuum cleaner

[CitizenVectron]

Or something else, don't know.

 

 

 

I hope something useful can be discovered, because so far all the carbon capture tech has been very wasteful, and, frankly, pointless.

Have we tried calling all the pollution and greenhouse gasses super gay so they leave?

MegaMaid is what I came to see, and I was not disappointed! This thread has gone from suck to blow!

The dumbest idea I've heard is to just pull it out of the air, compress it until it becomes liquid CO2, and then injecting it into retired oil fields.  This seems like a recipe for disaster, as sabotage or failure of the containment would just lead to this CO2 quickly escaping back into the atmosphere.  Not only would this cancel out all of the gains you made by pumping millions of tons out of out the atmosphere, it would be extremely hazardous to anyone nearby the leak. Just look at what happened in Africa in the 1980s from a natural release of CO2.

 

Carbon capture all has to include transformation of the carbon into some sort of stable solid, otherwise it's just a waste.

So that giant decarbonation plant was a bust. Nature already has the answers,it's etched on her rings, ebbs, and flows. Stop trying to shoehorn profit into this.

What could we do to build large systems that collect CO2 and are good for life?

 

I'll have to to go to my thinking spot to ponder how it can be done.

yep. Injecting liquid co2 into oil wells is also what carbon capture and storage on coal and gas plants looks like lmao

The counter-argument to the dumb idea of putting CO2 underground (where it can escape in the future) essentially boils down to:

 

"Well what if it gets loose?"

 

"It won't!"

On the topic of carbon capture, the pilot plant in my province has been a failure.

They would need to be insanely fast growing and fireproof.

The problem with algae, or pretty much anything that is NOT a tree, is that is after it dies, it decomposes, and turns back into CO2. Trees can lock the carbon into solid form for centuries whether the tree is alive or dead. 

 

Algae is important though, as it might become an alternative source of fuel that can replace gasoline or diesel.  And it would be carbon neutral, too.

Where are the GMO trees at?!

[Patatat]

No idea, but I imagine folks are working on long life algae. Theoretically if you keep ideal conditions why would algae die?

Chinese scientists create starch from scratch

WWW.CHINADAILY.COM.CN

Chinese scientists have created starch, a type of complex carbohydrate found in plants, using carbon dioxide, hydrogen and electricity, according to a study published in the journal Science on Friday.

 

Something along these lines is the future of carbon emission capture and processing.

This solution is not an easy one to deploy, however, because algal blooms bring many problems to the local ecosystems. Often referred to as harmful algal blooms (HABs), these rapidly growing algae clusters are devastating to the oceanic communities they touch. They increase acidity, lower temperature, and severely deplete oxygen levels in waters they grow in [9]. Most lifeforms aren’t prepared to handle environmental changes that push them out of their niches, so it’s easy to see why HABs kill significant portions of marine life.

Wildfires have unleashed 4.7 gigatons of CO2 so far in 2021, compared to 2.7 gigatons released by the EU, according to the International Energy Agency. Massive blazes in Siberia are a major factor.

I would imagine self contained algae farms so as not to harm the ocean/freshwater sources would eventually be possible

[Patatat]

And yeah as stated if the trees have the potential to burn anyway it doesn't necessarily do you all that much good. I suppose picking the right biomes for tree farms would help but trees are pretty high maintenance (trimming, brush removal, etc). Even somewhere with historically high rainfall can turn into a tinderbox if not managed properly

 

Like people are trying their hardest to repopulate rainforests (ideal biome) but are failing in terms of overall carbon burn. Like the energy put into tree farms is pretty carbon intensive iirc.

the catch, unsaid, is that it requires more energy in to create starch or any other complex carbohydrate than is generated by burning hydrocarbons to begin with. the enthalpy of combustion is highly favorable towards the production of heat and CO2 so unless they've discovered a very good catalyst it's a major energy sink. The whole situation would be easier to manage by simply not burning hydrocarbons in the first place but as i understand it that is generally off the table politically

If only we had energy sources that aren’t generated by hydrocarbons
