Carbon nanotubes offer new way to produce electricity

Scientists have discovered that a moving pulse of heat traveling along the miniscule wires known as carbon nanotubes can cause powerful waves of energy.
These “thermopower waves” can drive electrons along like a collection of flotsam propelled along the surface of ocean waves, creating an electrical current. The previously unknown phenomenon [...]

Rubber sheets harness body movement to power electrical devices

Engineers from Princeton University have developed power-generating rubber films that could be used to harness natural body movements such as breathing or walking in order to power electronic devices such as pacemakers or mobile phones. The material, which is composed of ceramic nanoribbons embedded onto silicone rubber sheets, generates electricity [...]

Producing carbon nanotubes on an industrial scale

Carbon nanotubes promise to revolutionize everything from medicine to electronics and power generation. Unfortunately nanotubes are notoriously hard to work with and chemists worldwide have struggled for years to even make them. Now researchers have unveiled a method for the industrial-scale processing of pure carbon nanotube fibers that builds upon the tried-and-true processes [...]
