We'll ultimately need a bunch of techniques working together. I suspect this would even be effective with less than 1. But really, what's the cost? That's the main factor. It may be a reasonable way to shove money at poorer countries to do manual work to solve the rich countries' problems.

Everyone's problem, no?

Not really. Poor countries don't have expensive infrastructure investments in the current climate, so can adapt to climate change by moving a few miles. Moving New York City and Los Angeles is much harder, and the loss much more expensive.

Yes, olivine is highly abundant, but due to lack of demand, most of it is currently staying underground. We seek to change that. We are looking for synergies like that, such as covering eroding beaches, breakwaters, etc with olivine. If you are interested in sand in construction and otherwise, I highly suggest you check out the book The World in a Grain. The importance of sand in our everyday life blew my mind. I mea…

a processor made out of silicon sand, the screen is made of quartz sand The processor is made from silicon, plus trace amounts of aluminum, glass, and other materials. Silicon is smelted from silica, which is silicon dioxide; same difference as hydrogen gas and water, iron and rust, or aluminum and ruby. The common crystalline form of silica is quartz, which is the most common sand (precisely because olivine sand wea…

Yes, I was just quickly paraphrasing the major takeaways on the impact of sand and its importance in our lives from the excellent book I referenced, The World in a Grain. Here is an excerpt for you and any others interested:

"He rummages through his knapsack, then pulls out a plastic sandwich bag full of white powder. “I hope we don’t get arrested,” he says. “Someone might get the wrong idea.” ... But it’s the mineral in Glover’s bag—snowy white grains, soft as powdered sugar—that is by far the most important these days. It’s quartz, but not just any quartz. Spruce Pine, it turns out, is the source of the purest natural quartz—a species of pristine sand—ever found on Earth. This ultra‑elite deposit of silicon dioxide particles plays a key role in manufacturing the silicon used to make computer chips. In fact, there’s an excellent chance the chip that makes your laptop or cell phone work was made using sand from this obscure Appalachian backwater. “It’s a billion‑dollar industry here,” Glover says with a hooting laugh. “Can’t tell by driving through here. You’d never know it.” ... Most of the world’s sand grains are composed of quartz, which is a form of silicon dioxide, also known as silica. High‑purity silicon dioxide particles are the essential raw materials from which we make computer chips, fiber‑optic cables, and other high‑tech hardware—the physical components on which the virtual world runs. The quantity of quartz used for these products is minuscule compared to the mountains of it used for concrete or land reclamation. But its impact is immeasurable."

Because it's biodegradable, the carbon it removes is only temporary. Also you are lying when you say it removes carbon from the atmosphere day and night; some Trees remove it during the day, while others remove it at night, but none do both.

Forrests hold carbon permanently.

Well jeez. I know it's not a popular thought on HN, but climate change is a problem of such scale that it's going to need government-level funding and oversight to find and validate geoengineering solutions, and global-level funding and coordination to implement them. This third-way aspiration to a non-government solution just seems like a pipe dream.

The important part is pretending something will be done (ideally by someone else), not actually tackling it.

Yikes... I know coral and other invertebrates are very sensitive to heavy metals like nickel.

We will be testing the sources of olivine for nickel, and as posted upstream, we have potential solutions for phytomining the olivine reserves for nickel with nickel hyper-accumulating plants, and then burning plants, retrieving the nickel ore and using the proceeds it to further fund operations...

What's preventing the whole operation from going sideways and spewing pollution? With no economic incentive to do it right, and the impact almost impossible to measure, it could quicky devolve into environmentalism theater.

Could it be the case that contemporary governments and economies are just simply not structured to be forward thinking in this way?

What if, in analogy to the transition out of feudalism, the next evolution of government and economies is one that allows for spending on future outcomes in a way that is impossible now? I have no idea what those institutions would look like -- I only know that hoping to solve global problems with the caveat that it needs to be profitable for someone has a whiff of obvious nonsense to me. And I also know, that at least in the US, the prospect that the government will implement large-scale change is patent nonsense.

Hi, if you'd like to donate at this point please check out https://projectvesta.org/donate where we currently have our "Grain of Hope" necklace available. It is a single grain of olivine, suspended in a sand timer vial, to symbolize that although time is ticking, it is not too late to stop (and reverse) the damage. Since we do not have a beach yet where we can place olivine, we were originally not planning to offer t…

Just bought one for my wife! It would be cool if I could kick in a few extra dollars so you could send one to every female American congressman and senator.

No need to make it a weird gender thing.

Lol. Im sure $150 co2 sensor will be able to detect co2 concentration in the atmosphere of our planet. Climat is a very delicate system. Once we remove too much there might not be enough time to reverse this.

Yes, “lol”, it will. In fact you don't even need to spend US$150. Your ignorance is not a good reason to sneer at people who are doing you the favor of sharing their knowledge with you.

Well, the problem with most of these off the shelf , indoor sensors, is that they are calibrated to current reading of about 400ppm, that's their base. To correctly measure CO2 you will need something that does not depend on that value to self-calibrate. What's more, some of them can have +/- 20ppm or worse accuracy. If the average annual ppm increase is 2ppm you can't reliably see the increase on your home device. To do that you need to have something that's NIST calibrated, with correct accuracy, set in a right place, and gather the data for longer period of time. You will need to smooth the data, and know how to interpret it.

No, trees grow, thrive, die, and then decay releasing the CO2 they'd absorbed in life as well as nutrients used by other life. You have to bury the lumber from a forest far from oxygen to get it to remove CO2 permanently. Also, forests only counter ~1 watt of gasoline combustion per square meter or so. That's only enough to sustain a pre-industrial standard of living as it did, in fact, do Back In The Day.

What if we accidentally trigger an ice age.

This is a legit worry. The same material we use to stabilize the climate could be the same material that throws it into a negative feedback loop. This happened during the ice age, which is exactly stated in the article.

Okay, no, it's not. You're being silly. We could always fire the Clathrate Gun... (^_^)

But you bring up an interesting point: there's no going back. This really is the Anthropocene Age and we're going to have to manage the planet from now on, now that we can, now that we know.
