One of the biggest challenges for the solar power industry is to boost the power-conversion efficiency of solar cells. In response to that, a duo of MIT (Massachusetts Institute of Research) researchers have found a little helper in a virus called M13.

Researchers at the Massachusetts Institute of Technology (MIT) report that they have used carbon nanotubes to concentrate solar energy 100 times more efficiently than regular photovoltaic cells. The researchers, reporting in the journal Nature Materials, said that the nanotubes — hollow tubes of carbon atoms — could form antennas that effectively capture and focus light energy, (more…)
Researchers at the Massachusetts Institute of Technology say they have developed a positive electrode made of carbon nanotubes that enables lithium-ion batteries to deliver ten times more power than a conventional battery.
If produced on an industrial scale, these carbon nanotube electrodes could significantly extend the range of electric vehicles, the MIT scientists say.
Reporting in the journal, Nature Nanotechnology, the MIT researchers write that the secret to their technology is that their carbon nanotubes contain a very high surface area for storing and reacting with lithium.
