Various departments at a car manufacturing plant are suffering from regular process outages due to voltage dips. These dips are causing production losses in the Metal Operation, Spray Coating, and Assembly departments that directly affect the productivity of the plant. The cost of those losses is directly related to the profile of the voltage dip (duration and depth). Various options to reduce these costs are investigated, with particular emphasis upon the Spray Coating and Assembly departments. The following conclusions can be drawn: 1. The number and type of dips occurring at the point of connection of the plant is regular. It is similar to what is monitored at other medium voltage stations that have the same grid structure. 2. A detailed analysis of the spray coating process reveals that installing a 'restart on the fly' system on the large conditioning fans substantially reduces the related voltage dip losses. 3. A detailed analysis of the Assembly department shows that there are two main bottlenecks that determine the restart time after a dip (the 'Drive' sub-process and the 'Cockpit', 'Marking', and 'Transport chain' users). These bottlenecks can be removed by installing a Dynamic Voltage Restorer (DVR), which results in a payback time of 1.4 years. * 1 Introduction

"start up company Vu1 is adding another light bulb option (not to mention acronym) to the mix, the Electron Stimulated Luminescence (ESL) bulb. The Vu1 ESL innovation re-purposes technology from our tried and true friend, the cathode ray tube (CRT) television. ESL uses accelerated electrons to stimulate phosphor and create light, thus making the bulb surface glow."

As the grave and unpredictable nuclear crisis in Japan continues, energy experts both internationally and domestically are questioning the viability of nuclear to deliver safe and reliable energy

Interesting article from New Science describing how a "coronal mass ejection" from the Sun could melt down the electrical power gird. ".... Over the last few decades, western civilisations have busily sown the seeds of their own destruction. Our modern way of life, with its reliance on technology, has unwittingly exposed us to an extraordinary danger: plasma balls spewed from the surface of the sun could wipe out our power grids, with catastrophic consequences..." The article does offer a solution: upgrade the ACE solar satellite, to detect an electro magnetic surge and provide power grid operators with about 15 minutes to shut down their systems. The article does not discuss another possible option: stop building centralized power sources that demand increasingly massive power grids. Instead, concentrate on meeting energy needs using localized sources of power; like the highly portable Hyperion Power Module.

My Clean Break column today is actually more of a feature looking at compressed-air energy storage (CAES) and how Ontario, geologically, would be an excellent location to give it a try. About 50,000 natural gas and oil wells have been drilled in southwestern Ontario over the past 150 years and most of them are depleted. Turns out that depleted gas fields are one of several types of underground reservoir that can be used to store compressed air. Salt caverns are another option, and we have plenty of those as well. In fact, 60 per cent of Canada's natural gas storage is in the region. Compressing and storing air wouldn't be that different technically. Another benefit is that southwestern Ontario has strong wind resources, so building a 1,000 MW-plus CAES facility on its own or as part of a partnership with area wind developers could prove quite economical. The idea, of course, is that cheap wind power generated overnight when demand is down could be used to compress and store the air. The air could then be released to generate electricity during daytime peaks, making wind a dispatchable resource in Ontario and more of a realistic replacement for coal power as it gets phased out of the province. Surplus overnight nuclear power, when we have it (mostly during the summer), could also be stored this way.

Storing solar energy in batteries remains costly and inefficient. But that may not be true for much longer. MIT researchers have discovered a way to store solar energy that could make solar power in homes a mainstream energy option and might even make power companies obsolete, at least for residential needs.
