Incredible Shrinking Microgrids
Microgrids are distributed islands of power generation and/or consumption connected to a much larger electrical distribution system. A key is the ability to separate and isolate from utility distribution systems during a grid disturbance. Power magazine says enabling technologies for microgrids are intelligent power electronic interfaces and high-speed switches.

Hot Tub-Sized Nuke
Have space for a spa or a power plant? A modular nuclear power plant will be about the size of a backyard hot tub. Power Engineering reports on a solid state reactor that generates 27 MW of power over five years. After five years, the manufacturer replaces the spent unit, and refuels the original module for re-use.

Top Three USB 3.0 Rumors
USB 3.0 will be a new connector standard operating at faster speeds than previous USB generations. This Intel Blog debunks three popular rumors. The first rumor is that Intel is creating the USB 3.0 spec. Not true, Intel is instead creating the host controller spec, a guide to building USB 3.0 compatible silicon.

Datapaths Improve Connector Performance
Switched-fabric architecture printed circuit board standards like Ethernet, PCIe, Rapid I/O, and InfiniBand reduce pin counts and board area needed for board-to-board communications. These architectures use direct point-to-point datapath connections to improve electrical characteristics and increase bandwidth over parallel-bus schemes.

Touch Me
Driven by consumer demand, touch screen shipments are expected to grow to $4.4 billion by 2012, up from $2.4 billion in 2006. Engineer Live says that projected-capacitive screens are displacing resistive screens in many cases. Projected capacitive screens are more durable, have better transmittance, and are often worth the extra cost. [A short registration may be required.]

Virtual Prototyping Trims Development Time
Ink jet printheads were one of the first MEMS applications to be commercialized in a big way. Eastman Kodak continues the MEMS trend with the development of their new inkjet printer. Small Times shows how Kodak used virtual prototyping to cut development time from a typical eight to ten years to just three years.

Mini MEMS Mike Mobilizes
Making conventional devices smaller and less power hungry is a key MEMS advantage. This low power mike is one quarter the size of competing products. EE Times says that expected applications include mobile and Bluetooth headsets. The mike's small size will allow arrayed microphones for noise cancellation and beam-steering.

Are Manufacturing Jobs Moving?
Automation, not some foreign government, is the chief cause of manufacturing job losses worldwide. Or so claims this Control Design column. The author uses compelling facts and figures to show how automation destroys manufacturing jobs by increasing productivity. But according to this article, there's no need to worry because that process is a good thing. Increased productivity, it notes, boosts living standards across the globe. It also generates the capital needed to create other jobs.

Make Your Own Solar Cell
You can buy cheap solar cells from Radio Shack, but where's the fun in that? This oldie but goodie article from scitoys.com shows you how to make your own solar cells from cheap materials without using any special tools. They might not be quite as efficient as the ready-made units, but the completed product can generate up to 50 microamps in bright sunlight.
