Thank you for posting this very interesting document, Andrew. On line 365 we find the statement characterizing CDR technology as being new, untested, and thus a large question mark in the equation.
The cheapest, fastest, and easiest way to pull CO2 out of the environment is my pulling it out of the ocean water. The technology to do this is known as the Perpetual Salt Fountain and that technology has been well known, at the scientific literature level, beginning in the 1930s. I do applaud the investigators for such an ambitious effort. Such a system of systems evaluation tool can be of tremendous importance. However, I would like to, on the other hand, encourage them to drill down into each and every technology that they know of but also to seek out those that are not being widely discussed. In brief, don't become an echo chamber. Consideration of the issue of coupling multiple CDR technologies is not apparent in my reading of this document. It is my view that, coupled technologies represent a whole new approach to the CDR equation which can actually include SRM qualities. If we take a look at Marine Cloud Brightening for example, it has both CDR, as it can assess primary production by cooling the water through it shade, as well as its primary qualities of SRM and can be easily coupled with Confined Marine Biomass production and Accelerated Weathering of Limestone. Those three technologies can exist on the same Oceanic platforms and would generate effects locally, regionally, and on land and sea if marine biochar (Blue Biochar) is factored in. It is my view that the investigators have properly crouched down in their starting position with their feet firmly against the starting blocks and with their eyes locked forward. And it is an impressive posture. Being completely and utterly comprehensive in their scope of the technological options and or the combination of those options, will be the first hurdle they must clear. I will watch closely their performance in this very important effort. Lack of absolute inclusion of each and every possible option and or combination of options will be a failed first hurdle.
