Limestone / chalk / calcium carbonate is the basic
material for building coral reefs and all manner of shell
structures in the animal world.
Now, courtesy of the Butter Mountain, The Shell
and Big Energy, we bring you the greenest building
material available... limestone made by
in the carbon sequestration ponds of a power station
Bubbling CO2, released by the burning of fossil fuels,
through water in a strong saline environment heavily
populated by and especially prepared for, small shellfish,
means we can sequester the CO2 and lock it into calcium
carbonate while we use the excess calcium stored in all
that unconsumed dairy product the world seems to
It may not save the planet but at least you'll get a warm,
fuzzy, sanctimonious feeling, knowing you "did

Shells, shells and more shells [AusCan531, May 15 2012]
||My I suggest increasing the salinity of the ponds so cockles grow in abundance without predators as on Shell Beach [link]. 7 to 10 metres deep - not even any sand evident. In fact, many of the buildings in the area are built from the coquina (shell formed limestone) which makes them literally Carbon Sequestration Houses.
||I've long wanted to build a home with limestone
blocks quarried from a deposit on the cattle station
where my mother grew up. It's old limestone, full of
crinoid fossils and Devonian oddities.
||You have to supply calcium as well as carbon dioxide. Guess where most calcium comes from? By heating calcium carbonate to break it apart....
||That's why I'm using surplus dairy products to supply
the calcium, [Vern].
