Nanotube power

Researchers at MIT have recently developed an energy technology that produces DC voltage by slingshotting electrons through a carbon nanotube. The discovery is so monumental that an entire branch of science and engineering may need to be created just to deal with the new form of energy production. In more practical terms, a thermpower device made of carbon nanotubes could provide the same energy output as a lithium-ion battery but at 1/100th the size. Imagine your laptop being powered by something the size of your fingernail!
