He sent me a link to a BBC video clip, showing the new 20 GPa nanotube fibers being created, an audio clip giving a short explanation of how it’s done and another audio clip explaining why these are suitable for body armor.
All three clips can be found here.
Thank you Akira!

04FEB2008 – Correction. The best fiber strength was measured at 9 GPa, not 20 GPa as I (and others) initially reported.
