ScienceDirect - Renewable and Sustainable Energy Reviews : Life cycle inventory analysi... - 0 views

  • Material flows and emissions in all the stages of production of zinc, copper, aluminum, cadmium, indium, germanium, gallium, selenium, tellurium, and molybdenum were investigated. These metals are used selectively in the manufacture of solar cells, and emission and energy factors in their production are used in the life cycle analysis (LCA) of photovoltaics. Significant changes have occurred in the production and associated emissions for these metals over the last 10 years, which are not described in the LCA databases. Furthermore, emission and energy factors for several of the by-products of the base metal production were lacking. This review article aims in updating the life cycle inventories associated with the production of the base metals (Zn, Cu), and defining the production paths and emission and energy allocations for the minor metals (Cd, Ge, In, Mo, Se, and Te) used in photovoltaics.

This Machine Might* Save the World | Popular Science - 0 views

    The source of endless energy for all humankind resides just off Government Street in Burnaby, British Columbia, up the little spit of blacktop on Bonneville Place and across the parking lot from Shade-O-Matic blind manufacturers and wholesalers. The future is there, in that mostly empty office with the vomit-green walls -- and inside the brain of Michel Laberge, 47, bearded and French-Canadian. According to a diagram, printed on a single sheet of white paper and affixed with tape to a dusty slab of office drywall, his vision looks like a medieval torture device: a metal ball surrounded on all sides by metal rods and bisected by two long cylinders. It's big but not immense -- maybe 10 times as tall as the little robot man in the lower right corner of the page who's there to indicate scale.

Voltage dips at an automobile manufacturer | Leonardo ENERGY - 0 views

  •  
    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

Global sustainability and key needs in future automotive design - 0 views

    Environ Sci Technol. 2003 Dec 1;37(23):5414-6. Global sustainability and key needs in future automotive design. McAuley JW. Basell USA Inc., 912 Appleton Road, Elkton, Maryland 21921, USA. john.mcauley@basell.com Abstract The number of light vehicle registrations is forecast to increase worldwide by a factor of 3-5 over the next 50 years. This will dramatically increase environmental impacts worldwide of automobiles and light trucks. If light vehicles are to be environmentally sustainable globally, the automotive industry must implement fundamental changes in future automotive design. Important factors in assessing automobile design needs include fuel economy and reduced emissions. Many design parameters can impact vehicle air emissions and energy consumption including alternative fuel or engine technologies, rolling resistance, aerodynamics, drive train design, friction, and vehicle weight. Of these, vehicle weight is key and will translate into reduced energy demand across all energy distribution elements. A new class of vehicles is needed that combines ultra-light design with a likely hybrid or fuel cell engine technology. This could increase efficiency by a factor of 3-5 and reduce air emissions as well. Advanced lightweight materials, such as plastics or composites, will need to overtake the present metal-based infrastructure. Incorporating design features to facilitate end-of-life recycling and recovery is also important. The trend will be towards fewer materials and parts in vehicle design, combined with ease of disassembly. Mono-material construction can create vehicle design with improved recyclability as well as reduced numbers of parts and weight.

R-Squared Energy Blog: How to Run a Car on Water - 0 views

  • So, the moral is: Sometimes it appears that the lunch is free, but the bill eventually comes anyway - when you have to replenish the catalyst.
  •  
    Oh, it can be done. There are no scientific laws that say you can't run a car on water. In fact, a Japanese company is the latest to claim they have pulled it off. See the video here: Water-fuel car unveiled in Japan However, what you can't do is run a car on water without energy inputs greater than you get from splitting the water.

    The incandescent lightbulb that wastes 90% of the electricity as heat is dying, we all know that. But a new breakthrough in solid state lighting might also kill compact fluorescent lightbulbs (CFLs) faster than some expected. Scientists at Purdue University have figured out how to manufacture LED solid-state lights on regular metal-coated silicon wafers (more details below). What this means is: much lower costs.

IET Forums - electricity so unbelievably powerful - 0 views

  • Take an artificial pacemaker. This device transmits an electrical voltage to the biological pacemaker cells of the heart. In a healthy human, these pacemaker cells generate their own action potential, an electrical waveform of about 100 millivolts. This may not sound like much energy until we remember that this electrical potential is sustained across an insulating membrane only five nanometers thick. That is 5 billionths of a meter. So the energy of an action potential is almost 20,000,000 volts per meter. Compare this to the 12,000 volts per meter at a standard wall plug. Healthy pacemaker cells spark the electrical wave that drives heart muscle contraction. When these cells malfunction, an artificial pacemaker may be implanted to take over. Waves of electrical voltage generated at the metal lead of the artificial device cross over to living tissue and initiate normal muscle contraction.

Technology Review: A Cheaper Battery for Hybrid Cars - 0 views

  •  
    The future market for hybrid-electric vehicles, at least those that are affordable, isn't necessarily paved with lithium. Researchers in Australia have created what could be called a lead-acid battery on steroids, capable of performing as well as the nickel-metal hydride systems found in most hybrid cars but at a fraction of the cost. The so-called UltraBattery combines 150-year-old lead-acid technology with supercapacitors, electronic devices that can quickly absorb and release large bursts of energy over millions of cycles without significant degradation. As a result, the new battery lasts at least four times longer than conventional lead-acid batteries, and its creators say that it can be manufactured at one-quarter the cost of existing hybrid-electric battery packs.

    Sunset technologies tend to be resilient against reports on their demise. But eventually, they have to go - cf carburators, word processors, ... But some of us have a chance to retire before the lead-acid battery does.
