If all factory and coal fired power station emissions were compacted into solids this would greatly improve local air quality.

yes… only question being where you are getting the energy from to do this??

I think the solution to coal emissions and dust is to rebadge as the new latest craze and people can keep it in a jar at home

I guess for coal fires power stations the energy could come from that. The processing planet could be right next to it.

For factories solar power, wind power and the grid. Energy can be passed around.

Otherwise if its not yet feasible then just keep it for the power stations.

I think it likely that any coal fired power station that was turning its gas emission into a solids would be running at a net energy deficit

Compacting coal emissions into diamonds

they would be crude diamonds

you could store them in a jar

Carbon dioxide will not remain a solid at earthly conditions. The energy to compress it to a solid exceeds the energy created from burning the coal that made the carbon dioxide, and even once you’ve done it, you will need to continue to expend energy to store it under pressure.

The compacting plant could be solar powered.

I wonder how much energy It would take to convert emissions into solids?

It might only take a fraction of energy that is generated, for the compacting of gas?

It would not have to compacted so hard to be diamonds, but if that could be done at a reasonable cost then a product could be made out of a waste, they would probably be crude diamonds but still useful for cutting etc.

That’s if it can be done that is, and also be economically feasible.

The diamond rain made the labs stays at that pressure doesn’t it?

Once diamonds are diamonds they stay that way don’t they?

The idea is to compact the co2 into diamond.

but maybe it could be compacted into another material?

I suppose one could take the idea further.

I wonder if each element could be compacted into its next denser element on the period table?

I realize it takes a lot of energy to make these diamonds.

But what if a really efficient way could be found?

Just wondering?

but are diamonds made from CO2 in the first place, answer, no? then what do you hope to achieve?

CO2 solidifies into dry ice at about -78.5°C at 1ATA. Cooling it to that temperature — especially from the hot gas produced in a coal burner — will take a lot of energy.

Bubbling CO2 through a saturated solution of Ca(OH)2 in water will produce a residue of CaCO3 and H2, which is a solid and occurs naturally in the shells of molluscs.

You do realise that diamonds are made of pure carbon, not CO2, don’t you? And that the oxygen atoms are covalently bonded to the carbon atom? And that breaking those bonds will cost more energy than was extracted in forming the bonds?

I don’t believe that had actually occurred to him until now.

Sorry, should have checked that before I posted it. The result of bubbling CO2 through Ca(OH)2 is the solid CaCO3 and H2O (water). It’s CaCO3 that’s found in mollusc shells.

Also, for TN, no, diamonds don’t always stay that way. For example, if you heat a diamond to about 1000°C for about an hour, it’ll revert to its graphite form (somewhat spectacularly.)

Then there’s no point.

Why bother having a 1 GW coal powered plant that needs a 20 GW solar power plant to compress the carbon dioxide, when you can just have a 1 GW solar power plant instead?

Compression alone won’t covert carbon dioxide to diamond: it’s a chemical reaction, a reduction.

But roflmfaotff the energy needed to make diamonds is phenomenal… your plan is to turn billions of tonnes of carbon dioxide to diamond?

Which would flood the market causing a massive price drop.

It would be interesting, though, to see if it is possible to burn carbon in compressed air so dense that the resulting carbon dioxide solidifies when cooled to ambient temperature. Not practical, but interesting.
