Carbon nanotubes will be the future of heatsinks. They offer a great deal of thermal conductivity over todays heatsinks.

He found that the light restructured the tubes into horn-shaped configurations, surprising since carbon bonds need temperatures between 1,500°C and 2,000°C to break and reform. Also, multiple-walled carbon nanotubes, carbon soot and samples of Buckminsterfullerene (C60) were not affected by the light, which came from an ordinary photographic flash lamp. Ignition in the presence of oxygen required a local temperature of 600°C to 700°C, which could be achieved at a threshold illumination of 100 milliwatts/cm2.
