We propose a statistical and macroscopic analysis to estimate the catalyst activity of water-assisted growth (super-growth) single-walled nanotubes (SWNT) characterize SWNT forests. The was estimated be 84% (+/-6%), highest ever reported. forest found very sparse material where SWNTs represent only 3.6% total volume. This structural sparseness is believed play critical role in achieving highly efficient growth.
