Hi Sev, interesting paper. Where are you proposing to get your hydrated
silicon from? I did not see that in your discussion. Have you thought of
simply including ground olivine in your flakes?
Regards, Oliver.

Geoengineering is a near continuum. Jostling for pre-eminence between
CDR and SRM approaches is both unnecessary and weakens our collective
voice. Some geoengineering concepts span both categories. My concept
of /Organic Mariculture and Biosequestration/ is one such newcomer. It
uses rice husks coated with iron-silicon-phosphate rich material to
produce buoyant fertiliser flakes which deliver natural, ultra-slow
release nutrients to oceanic phytoplankton. Disseminated to suitable
and nutrient-deficient oceanic sites, these flakes are expected to
cause increased: marine biomass; carbon flux to the sediments of deep,
cold oceans; and albedo from the additional chlorophyll, DMSP-derived
cloud cover, and DMS-derived sulphate aerosols. By my rough
construction, they may be made to do this profitably, at scale, and
with acceptable speed and safety, once the science has been validated
and approvals obtained. The concept also benefits from offering a
sustainable, reversible and likely-politically-acceptable solution in
which all nations may participate and receive net benefits.
I ask this community to consider the attached summary. Supporting
documents are available from me at [email protected] for those
interested, or these could be posted online here should the demand be
there. I am emboldened to make this request for constructively
critical discourse because the work has been encouraged by Martin,
Lord Rees, the immediate past president of The Royal Society in a
personal communication and because of our desperate need for viable
solutions.
