MIT Researchers Discover New Electricity Production Method

The storage and generation of electricity is a hotbed of scientific study around the world. New and improved methods of storing electricity have a myriad of potential uses from phones and laptops that run longer to new electric vehicles with much greater driving range.
At the center of much of the research in the storage and generation of power in batteries and other devices are carbon nanotubes. The carbon nanotube has been studied for decades and new advances over the last few years have made the nanotubes easier to produce and have offered breakthroughs in the use of carbon nanotubes. Scientists at Rice University made a breakthrough in carbon nanotube processing in November of 2009 that uses processes similar to those that have been employed in the plastics industry to make the production of carbon nanotubes in bulk much easier.
Researchers in late 2009 also found that defective carbon nanotubes are more efficient at storing energy than carbon nanotubes that are uniform in size. In February 2010, Bayer announced that it was opening the world's largest carbon nanotube production facility to develop carbon nanotubes dubbed "Baytubes" using multi-wall carbon nanotube technology. The facility is expected to produce about 200 metric tons of nanotubes each year.
Now, a team of researchers at MIT have announced that they have made a new breakthrough for producing electricity with carbon nanotubes. The discovery may one day lead to a myriad of new devices such as sensors the size of dust that can be dispersed in air to monitor the environment or the tech might lead to implantable devices that produce their own power. The researchers discovered a phenomenon that was previously unknown that produces powerful waved of energy that shoots though carbon nanotubes, producing electricity.
