All industrial activities have considerable impact on the environment. Emision, wastes and use of energy result in pollution and depletion of natural resources. Thus, sustainable development  stands for progress.Maintenance is an important part for improving life cycle, energy, safety and envionmental management. Maintenance to-day goes together with Quality Management, Environmental Management, Occupational Health and Safety Management and Social Responsibility. We have to develop Maintenance for energ-saving issues!

Without an electric drive with advanced lithium batteries, this is no different than what was originally developed. It could compete on the basis of price with the Aptera, which also is very sleek and thus requires fewer mega Joules to go the same distance. Perhaps, VW dealers can hope that shoppers won’t look for a plug. Now the question is, can it get a Five Star safety rating, like its competition?

Designers looking to save power and size are turning to advanced technologies, and motors are no exception. With piezoelectric technology at the heart, a new type of motor is improving small-scale motion systems in a big way. Electronic access control enhances security, convenience, safety, and flexibility in a wide range of applications from building automation to automobiles. Today, system designers are adding "smallest size" to the requirements list for the electronic actuators at the core of access control systems.

THE dream of climate-friendly, petroleum-free motoring is creeping closer - thanks to a clutch of breakthroughs in nanotechnology. Several recently reported lab findings promise to vastly improve the safety and performance of the high-capacity batteries that electric cars will need, at last making them a viable alternative to today's petroleum-powered vehicles.

Whirlpool is next in line to show off a concept that could purportedly hack down your energy bill

It seems that everyone is getting into the battery business, one of them will succeed in making a smaller, lighter and less expensive battery.  This development by ExxonMobil sound very promising. ExxonMobil Chemical and ExxonMobil's Japanese affiliate, Tonen Chemical have developed a thin film separator for use in lithium-ion batteries, that would enable production of batteries like those found in cell phones and laptops, to power cars and trucks. These new film technologies are expected to significantly enhance the power, safety and reliability of lithium-ion batteries, thereby helping speed the adoption of these smaller and lighter batteries into the next wave of lower-emission vehicles.

After safety, the longevity of the batteries in a plug-in hybrid is the greatest unknown. Can a plug-in hybrid’s battery pack retain the bulk of its energy capacity over 10 years of daily use and more than 4000 full-discharge cycles? (For a deeper look at the challenges facing plug-in hybrid batteries, see “Lithium Batteries Take to the Road”.)[ LINK: http://www.spectrum.ieee.org/sep07/5490 ] As Don Hillebrand of Argonne National Laboratory, in Illinois, said tartly, “Batteries are the showstopper.” Periodic demands from the grid, even for only a small fraction of the battery’s stored energy, would clearly affect the cells’ life span—but no one has data on how much. Another open issue is the development of creative financing models for replacement battery packs costing several thousand U.S. dollars even after mass production is achieved. Third-party battery leasing could be one answer, if combined with a secondary market for batteries whose performance has fallen below automotive levels. Carmakers, electric utilities, and large consumer-financing groups are quietly batting around these notions to see if they can build a financial model that makes sense for all three parties.

Ohio State University engineers are working to make the traffic control boxes that stand beside major freeways smarter. They've developed new software that helps the computerized boxes locate road incidents -- such as traffic back-ups or accidents -- and notify transportation authorities at lower cost, especially in rural areas.

But there are also those who try to steal electricity and PECO is trying to get the word out about how dangerous that can be. 

This 44-page guide includes discussions of safety, power quality and codes, legal and procedural issues, net metering, and electrical inspectors.
