“Scientists say…”
All of them, are you sure?
Geoengineering schemes are not agreed upon by many scientists. There are several types of geoengineering “solutions” and no agreement on any, just suggestions.I can’t help what the article is titled. 🤷♂️
What the diamond version of silicosis?
I don’t know, but I hear De Beers is already planning to corner the lung transplant market.
Yes, let’s just have everyone on Earth breathe in diamond dust all day every day. There’s no way that could be bad for our health.
There’s never been a case of something having different behavior or health effects just because of a tiny chemical difference (trans fat) or size difference (micro plastics), what’s the worst that could happen?
There have never been lung issues caused by inhaling very small dust particles, right?
So what would it cost to replace all fossil fuel energy with renewable?
You are missing the point, because we need to do that anyway.
The idea is to prevent things from getting worse in the meantime.
Replacing fossil fuels take time no matter how much we invest.ok but you just know corporations are going to use this as an excuse to keep using fossil fuels. like to them this is basically carte blanche to keep the status quo and block green energy from happening even harder. “oh hurdur har har we found a solution to climate change and it’s dumping diamonds in the atmosphere, no need to pay for green energy anymore haha” type shit
corporations are going to use this as an excuse to keep using fossil fuels.
Corporations follow the law, the only way to solove this is to have the laws required.
Corporations follow the law
Good one
Oh please, of course they don’t always, but the ones that don’t are generally forced to by oversight.
Yes I kn ow they generally get off easy, but then oversight is increased and if it continues, the penalties increase, until ultimately it will be forced to shut down if illegal activities continue.
So yes generally cooperations do follow the law.
That amount sounds like total bullshit. Diamonds can be manufactured and once that is done at scale, it won’t be all that expensive. Even at $10000 a ton, five million tonnes would cost just 50 billion.
That number is for doing it anually for 65 years. It lists roughly 18 billion per year for the cost.
But besides that, I think you are greatly underestimating the cost of the diamonds. Synthetic ones are way cheaper than natural ones, yes, but there’s a lot of room between “natural diamond expensive” and “actually cheap”. Going by these prices https://www.diamondtech.com/products/categories/diamond_powder_price_list.html
It’s $2.5 million per tonne. I assume you could get a cheaper price per weight if you’re buying five million tonnes of anything, but it’s still two orders of magnitude more expensive than you are guessing
Firstly, it’s 5 million tonnes per year. For 65 years. Secondly, the cost is for a 65 year SAI program, including developing the tech and running the missions. Thirdly, this is all explained in TFA or the links therein.
I don’t get it, why wouldn’t sapphire dust work? Isn’t that dirt cheap to make? And it’s carbon free!
Seems illogical to add carbon in the form of diamond, to a problem that is mostly caused by carbon?The carbon isn’t the problem, it’s the CO2 molecule. I would be really curious if solid carbon in diamond form is able to react with ozone in the atmosphere to make CO2, or if it would be inert, or if it would do something else.
It’s also Methane and CO, gasses that also contain carbon. I know diamond is pretty stable, but it does burn, and then it creates the gasses we try to avoid.
CO is not a significant greenhouse gas. (And N20 is…)
Are diamond particulates likely to burn if they’re dispersed in the atmosphere?
Are diamond particulates likely to burn if they’re dispersed in the atmosphere?
Actually yes, if they enter the engine of a plane they will burn.
True. That would be a minescule fraction of what’s there though…
Not quite minuscule, for every ton of jet fuel burned, 2 tons of oxygen is needed, to take that in, about 3-4 ton of atmospheric air goes through the combustion, the volume of that air is quite a lot, and is only sustained because oxygen is constantly renewed. The diamonds will not have self sustained renewal and will be burned up pretty quickly.
Also being an aerosol increases surface and potential chemical reactions by a magnitude of maybe a billion per unit, so although we consider diamonds to be very stable in their normal form, a diamond aerosol is obviously much less so, and UV light refracted could accelerate break down of the diamond aerosol, into free carbon, which will create carbon gasses. I bet researchers have considered this, but I see no numbers for it?I just wonder why not use sapphire dust instead. Doesn’t it reflect sunlight almost identically?
The artificially-inflated price of the diamonds should be irrelevant in this calculation.
