American Superconductor Achieves Full Power Of 5MW Ship Motor - SpaceDaily  Left:  The 5 MW rotor shown here developed under this contract will operate at 230 revolutions per minute (rpm) and represents a ten-fold increase in torque over the 5,000-hp, 1,800 rpm HTS motor AMSC built and tested during 2001. The low-speed, high-torque 5 MW HTS motor is a critical development milestone on the path to 25 MW and 36 MW motors, which are the power ratings expected to be utilized on electric warships and on large cruise and cargo ships. HTS motors of these power ratings are expected to be as little as one-fifth the volume of conventional motors.  
Researchers Use Semiconductors To Set Speed Limit On Light - SpaceDaily  Left: Simulation of slow light as optical signal enters and exits semiconductor quantum wells. Credit: University of California, Berkeley  In a nod to scientific paradox, researchers at the University of California, Berkeley, have slowed light down in an effort to speed up network communication. They have shown for the first time that the group velocity of light - the speed at which a laser pulse travels along a light wave - can be slowed to about 6 miles per second in semiconductors. The researchers envision a future of 3-D graphics transmission, high-resolution video conferencing as good as face-to-face encounters  

Towards Molecular Electronics - SpaceDaily  A team of engineers at Northwestern University has become the first to precisely align multiple types of molecules on a silicon surface at room temperature - an important step toward the goal of molecular electronics.  "Our process works at room temperature and on silicon, which suggests that it can be made compatible with conventional silicon microelectronics. Ultimately, we want to integrate with current technology, thus creating a bridge between microelectronics and nanoelectronics. "Previously we were working with single molecules on silicon," said Hersam. "This new process enables us to build more complex structures."
