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 mean the device you are using right now to access this website, has a processor made out of silicon sand, the screen is made of quartz sand. The building you are in is likely made of aggregate sand, and the road to get to your house etc. But also, don't forget that sand was used to make the lenses for reading that made possible for our older academics, extra decades of research and enabled us to carry out astronomy and to create microscopes...

Sand has shaped the world in such a massive way, and we are hoping it can save us from our CO2 problems as well.

Our goal is not to cover up existing tourist beaches. You would be surprised how much coastline around the world is undeveloped and not even accessible by roads etc, those beaches are likely to be the places where we go first.

That said, we believe that green sand beaches will become their own tourist attractions as the naturally occurring ones, such as Papakolea in Hawaii, are (which is the beach pictured on our site). They are beautiful and we are considering ways we could create ecotourism hubs for climate change education etc.

Because most rivers are now damned and sediment flows impeded, many beaches in developed areas are eroding away with no sources of replenishment. Beach replenishment/nourishment is a huge industry and there are not only sand shortages, but even sand mafias who steal sand. So as resorts have to replace their sand, in the future, they might consider creating olivine sand beaches.

We have had early interest from a few parties who own resorts with rocky beaches and would consider replacing their beach with green sand, but at this time, that is not our focus.

We are focused right now on getting a pilot project deployed that can definitively and irrefutably prove the minimum accelerated olivine weathering rate on a real-world, high-energy tropical beach.

The questions of ecotourism and specific beaches is what we will be dealing with as we move to Phase II-III. See an outline of our deployment plan here -> https://projectvesta.org/plan/
