Please describe the Wild Card (approx. 150 words)
Future breakthrough in high-temperature superconductors or carbon nanotubes (CNT) enable loss-less transmission of electrical power. Carbon nanotubes exhibit so-called "ballistic conductivity", which is effectively similar to superconducting. Technological breakthroughs in CNT production could lead to commercial super-strong long power lines with near-zero electrical resistance. The late Nobel laureate R. Smally was an ardent advocate of nanotubes as a solution to the energy crisis, by replacing old copper and aluminum power lines with CNT cables.
