SPLITTING ( CARBON from OXYGEN ) I searched out the internet to see if another had the answer to,
" can carbon be split away from oxygen " ?
Turns out it can be done
But... only from a dioxde to - monoxide.
The final answer in this dialogue i found amusing.
lol
PLANTS PERFORM THIS SPLITTING NATURALLY.
Synthesizing the co2.
Which brings the magnesium carbonate subect back to,
MgCO3 by itself, is used as a fertilizer.
No conversion needed.
Lots of literature on this subject.
Our Driftwood if modelled as a - fertilizer
would double in size....16.7 ( million tonnes )
Crops or plants ( fed ) MgCO3 would seq by digestion
Carbon would become - fixed - apart of plant.
Used as nutrition.
16.7 million tonnes and even if, $150 per tonne profit
could be achieved = still impressive numbers.
= $
2,505,000,000 billion Here's the discussion dialogue -
Emphasis on, last sentnce - plants....!
Q. Is separating carbon and oxygen from carbon dioxide possible?
A. Splitting carbon dioxide (CO2) into carbon and oxygen can in fact be accomplished, but there is a catch: doing so requires energy. If hydrocarbon fuels, which produce the greenhouse gas in the first place, supply that energy, thermodynamics tells us that the net result will be more CO2 than you started with.
The best existing technique is to electrochemically break carbon dioxide into pieces that will chemically react using a catalyst made of platinum. But platinum is a rare, expensive metal. And using electricity usually requires the use of fossil fuels adding to more CO2 in the atmosphere.
A better method is to use an electrochemical cell with a porous, foamy catalyst made of nickel and iron. Both metals are cheap and abundant. When carbon dioxide gas enters the electrochemical cell, and a voltage is applied, the catalyst helps the carbon dioxide to split off oxygen to form carbon monoxide. The carbon monoxide is very reactive and a useful precursor for making many kinds of chemicals, including plastics and fuels such as gasoline.
Not only does the new nickel-iron catalyst work well; it's actually more efficient than the expensive platinum process it could replace. The electrochemical cell using the nickel-iron catalyst gets almost 100% efficiency.
Are you trying to reverse entropy?
That takes lots of energy which, in an open system, is supplied by solar energy.
Surprise! Plants do this daily.

Driftwood could be easily crushed milled, separate silica
and turn the rest into - fertilizer grade.
