Wow! The article also includes a chart on the feasibility of various uses for
nanotubes. Apparently, imbedding nantubes into a matrix gets the lowest
feasibility rating, listed as "science fiction" :-( And the cost is ...let's
see....$1500 per gram...so 30 oz. of the stuff would cost $1,275,000.
Perfect! Very high cost and a long wait! Put me down for 2 nanomoldies. :-)
