RE: [geo] PUTTING COSTS OF DIRECT AIR CAPTURE IN CONTEXT

The plant is already ready, it is the Earth itself, that has already for 4.5 billion years captured the excess of CO2 emitted by volcanoes, otherwise life on Earth would have been impossible. So, instead of building a new plant, the solution is simple "Let the Earth help us to save the Earth", O

RE: [geo] It’s time to start talking about “negative” carbon dioxide emissions

Well, the message is clear, but when I propose the most scalable and proven process, and probably the cheapest way, not many people seem to listen. So again: 1:The weathering of olivine (and some similar rocks as well) has made life possible on Earth 2: Life itself (mainly marine life), by pract

RE: [geo] Slicing the pie: how big could carbon dioxide removal be? - Psarras - 2017 - Wiley Interdisciplinary Reviews: Energy and Environment - Wiley Online Library

What an utter nonsense to think that CO2 capture and removal by mining, milling and spreading olivine would cost in the order of 100 US$ per ton. If you don’t know anything of mining and mining cost, don’t come up with confusing and ridiculous guesswork. There are many olivine massifs on every
