New Freitas paper: Diamond Trees

Rob Freitas has a new paper up:

Robert A. Freitas Jr., “Diamond Trees (Tropostats):  A Molecular Manufacturing Based System for Compositional Atmospheric Homeostasis,” IMM Report 43, 10 February 2010

Abstract. The future technology of molecular manufacturing will enable long-term sequestration
of atmospheric carbon in solid diamond products, along with sequestration of lesser masses of
numerous air pollutants, yielding pristine air worldwide ~30 years after implementation. A
global population of 143 x 10^9 20-kg “diamond trees” or tropostats, generating 28.6 TW of
thermally non-polluting solar power and covering ~0.1% of the planetary surface, can create and
actively maintain compositional atmospheric homeostasis as a key step toward achieving
comprehensive human control of Earth’s climate.
