With the use of nanoconstructed filterspurifiers, drop to pennies per kg. Note that the superior material properties of diamond should allow products to be orders of magnitude lighter than metal, plastic, or even carbonfiber versions large humanscale products will be inflatable and will require tiny fractions of gram per cubic centimeter to maintain their shape.. Per feature Since fabrication is automated and bottomup, details dont any extra. However, the Phoenix design is deliberately crude lower bound, not bestguess estimate. Preliminary answer primitive design 10100 per kg, based on costs for energy as estimated in the Phoenix nanofactory paper and highly pure chemicals.
