Brazil Builds Big
Countries across the world are concerned about the price and availability of conventional power generation fuels such as coal and natural gas. POWERnews says that Brazil is addressing this issue with plans to build 50 to 60 nuclear power plants over the next 50 years. Each plant will have about 1,000 MW of capacity.

DOE Funds Solar Dozen
Rises in energy prices spur alternative energy development efforts. T&D World reports on U.S. Department of Energy (DOE) plans to invest $24 million in solar energy products to accelerate penetration of solar photovoltaic systems. DOE selected 12 industry teams to participate in cost-shared cooperative agreements focusing on hardware components.

Keep Your Fiber Clean
Fiber optic communication systems are more prevalent due to advantages in bandwidth and noise immunity. They can work well for years, but only if the connectors are properly installed and maintained. A Utility Products article presents proper maintenance for connectors, fibers, bulkhead connectors, and detector ports.

Find Ground Faults Before they Happen
Ground fault relays (GFRs) have grown in sophistication and now provide features beyond ground fault detection. Plant Engineering says some GFRs can continuously monitor leakage current. An analog signal output proportional to current can then be fed to a PLC or plant operations computer and analyzed to predict faults.

Choose the Right Capacitor
If you design printed circuit boards, you probably use capacitors for power-supply bypassing and signal coupling. This EDN article provides a useful primer on ceramic capacitors. Class 1 capacitors are a good fit for many applications because their temperature compensation provides the most stable performance of all the classes.

Some Sensors Like it Hot
Most magnetic sensors don't work at temperatures over a few hundreds of degrees Fahrenheit. This may limit their use in future high temperature applications like ceramic engines in cars and aircraft. This ISA article details how a new magnetic sensor will be able to operate at high temperatures without degradation.

Nanostructures Regulate Reactors
Chemical reactors are complicated and require complex control systems to ensure efficiency and prevent explosions. But a consortium of UK universities is developing Nanostructures to facilitate safer, greener, and more efficient chemical reactors. Nanostructures can regulate reactions, momentum, heat, and mass transfer inside reactors.

Who Will Run the Power Plants?
Along with many industrial sectors, the power and energy industries face a rapidly aging workforce. This Power Engineering article details independent but complimentary ways to deal with the problem. The first is through education of a new generation of workers through university and industry cooperation. The Swanson School of Engineering at the University of Pittsburgh launched its Power & Energy Initiative. The second is via knowledge transfer facilitated by sophisticated software systems.

Solar-powered Bikini
Here's one for female engineers. You finally arrived at the beach, but with no source of power for your iPOD or your cell phone. No problem, just plug into the nearest available solar bikini. Everything USB says the bikini provides 1.5 amps at 5 volts through a USB port. Solar swim suits for male engineers would be larger, and so provide more power for their electronic devices.
