Diamond Trees (Tropostats): A Molecular Manufacturing Based System for Compositional Atmospheric Homeostasis
Robert Freitas has a new idea for a product that could be built using molecular manufacturing -- diamond trees designed to sequester carbon dioxide. The concept is fleshed out in technical detail at a paper now available at the Institute for Molecular Manufacturing website. Let's bring up that 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 109 20-kg â€œdiamond treesâ€ 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 Earthâ€™s climate.
On the topic of MNT, I also wonder what it will take for the skeptics to become convinced that the technology is plausible. Positional atomic placement has already been demonstrated, including at room temperature. Will complex rotating 3D nanosystems convince them? I doubt those are far off.
