"Rarely is a processing advance so elegantly simple that rapid commercialization seems possible...Things move quickly if you can prove that the supply of the material is good" says Ray on his teams work.
Not only does this open up the standard ideas of flexible, and cheap electronics (as nanotubes are just carbon- one of the most plentiful of things we have these days), but developing materials on the nanolevel enables us to take advantage of 'molecular organization'. This may be a bit extending things, but as I have said before the ability to control materials at the molecular level is key to our future development of technology.
My first thoughts on electrically conductive nanotubes incorporate dye solar cell technology -enabling high efficiency solar cells at a fraction of their current cost. My mind then quickly drifts to the Space Elevator and how we may just be able to get rid of inefficient fuel burning airplane flight (not to mention space flight) - just take a solar powered crawler up the space elevator, and glide down to your destination. But that is just the beginning. ::Nature News ::Science
