The U.S. President’s Council on Advisors on Science and Technology requested public input on a number of manufacturing topics including “molecular-level, atomically precise production.” Foresight joined with our sister organization IMM to produce a statement on Atomically Precise Manufacturing, now posted on the OpenPCAST site, with public voting and commenting still continuing, so join in the [...]

New Freitas paper: Diamond Trees

Posted by J. Storrs Hall on February 18th, 2010

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 [...]

A Night in the Sun

Posted by J. Storrs Hall on December 7th, 2009

When I woke up this morning, it was nine degrees below zero, Celsius.  It’s solidly overcast here, and what’s more, this time of year the sun doesn’t get much more than 20 degrees above the horizon — in the middle of an all-too-short day. My house has a footprint of about 200 square meters.  At [...]

It’s 0067 AA

Posted by J. Storrs Hall on December 2nd, 2009

(Atomic Age, that is.) From the University of Chicago Library site: On December 2, 1942, scientists at the University of Chicago produced the world’s first self-sustaining nuclear chain reaction in a nuclear pile constructed in a squash court beneath the West Stands of Stagg Field, the University’s athletic stadium. This experiment, crucial to the control [...]

Nano PVs: cheaper or better?

Posted by J. Storrs Hall on November 17th, 2009

Over at Nanoclast, Dexter Johnson writes: It seems when nanotech is applied to photovoltaics it can either boost their efficiency to new heights or it can cheapen their manufacturing process. But it never seems to provide a solution to both of these. It’s always a tradeoff: increased efficiency but difficult manufacturing processes or a cheaper [...]
