Leveling the Load

Leveling the Load The on-demand power to which Western civilization is accustomed can be delivered only via excess generation capacity or storage capability. Renewable sources are rarely synchronized to actual demand, and even nuclear sources are not completely flexible in meeting demand peaks. According to this Power-Gen Worldwide opinion, the missing link is a load-leveling buffer. Some available options are compressed air storage, pumped heat, pumped hydro and batteries. Electric vehicles have garnered recent attention as distributed forms of energy storage that can be made available to the smart grid. The author sees a bright future in developing load-leveling components and technologies.

Plugging into Alternative Energy

Plugging into Alternative Energy Renewable and alternative energy systems call for high availability in supporting elements at all levels, even connectors. Wind and solar systems often reside in challenging field environments, and of course nuclear applications have demanding requirements as well. In this article, looks at some considerations such as obtaining maximum energy transfer, providing touchsafe fittings for safety and selecting proper materials.

Common Coupler

Common Coupler The Society of Automobile Engineers has released the "SAE Electric Vehicle Conductive Charge Coupler" Standard J1772 for connections between plug-in hybrid and battery-electric vehicles and electrical charging systems. The goal is to develop a standard corded connector and vehicle inlet, which together make the coupler. The development team included major automotive suppliers as well as electric utilities.

Poisonous Personnel

Poisonous Personnel We've all worked around them — poisonous employees who negatively impact you, your coworkers and the company as a whole. Managing Power identifies nine nefarious types with memorable names like the "politician", the "rooster", and the "funeral director". More important than the catchy names are the strategies offered to deal with each type.

Steal Your Best Work

Steal Your Best Work Check out this video for a different perspective on how we innovate. The speaker makes a case for not just "copying" superficially, but for "stealing" underlying principles to make a completely innovative "new" work. The concept has applications in technology fields as well as artistic endeavors. This author would never endorse theft, but often the nature of innovation involves standing on the shoulders of giants.
