Regulators Readily Reject Renewables
Power project regulators are rejecting new projects at record rates. Implying environmental issues, the premise is that emissions-free power is preferred. Despite widespread support from environmental groups, boston.com reports that MA regulators say no to clean power as well by rejecting underground power cables from a proposed wind farm offshore of Cape Cod.

Bridge Collapsed, Transmission Towers Won't
The Tacoma Narrows in Washington State became infamous by the collapse of the "Galloping Girdy" suspension bridge in 1940. Tacoma Power proceeded cautiously when replacing an 80 year old transmission line located near the old bridge site. The project included specially designed cables to avoid the galloping effect that downed the bridge.

Ceramic Connector Seals Superior
There are four main ways of sealing electrical connectors: simple epoxy, a mechanical seal with an elastomer o-ring, glass seals, and ceramics. This azom.com article says that ceramics are best, but are the most expensive option. Ceramics have high thermal and mechanical shock resistance, exceptional corrosion resistance, and superior dielectric properties.

Solid State Relays Stand Short Circuits
The new NEC article 409 and the latest version of UL508A require designs and products to adhere to short circuit current regulations. As reported in electronicstalk.com, manufacturers are starting to release a range of products that comply. Notably among the first are solid state relays with UL-approved short-circuit current ratings.

Nano-Encryption Names Products
RFID is already being used to track and trace Pharma products, but it has limitations. A Pharmaceutical Manufacturing article explains that RFID tracks the package, not the contents. Nano-encryption takes security to higher levels by identifying each pill or capsule, providing full, global traceability of products. Can Nano-encryption aid other areas as well?

Superior Spectrometry Sensor
Measurement of hydrocarbon gases in the process environment have typically been performed with Non-Dispersive Infrared spectrometry or Fourier Transform Infrared spectrometry sensors. Both of these technologies have serious limitations in such applications. An International Oil & Gas Engineer article says that Encoded Photometric Infrared spectrometry can be a better solution.

Be the Best Boss
This EDN article is directed to new CEOs, but it applies to anyone in a new supervisory role. The important points to practice are: to be yourself, get to know other key executives/leaders, contract with these leaders, involve your organization in implementation, avoid abrupt change to culture and traditions, and communicate early and often. These corporate coaching considerations can codify a career change challenge.

Open Source Comes to Cars
Open-source is a term that most associate with software products like Linux, Wikipedia, and sources of intellectual property, but might open-source also work for less ethereal products such as cars? Can cars even communicate with each other to avoid accidents? Engineering design professionals in Europe and North America think so. European Design Engineer discusses the progress that engineers are achieving in creating an open-source, environmentally friendly car. [A short registration may be required]
