The device is a piece of paper infused with carbon nanotubes and a salt, which serves as an electrolyte. Because it stores energy and conducts it, the device can act like a battery. A number of corporate labs and universities have come up with flexible batteries in the past. Power Paper from Israel makes a flexible battery printed on polymers that relies on zinc as an electrolyte. It sells it to the cosmetics industry. Japan Inc. also has trotted out a lot of prototypes. Still, these things haven't gone commercial so any advance is welcome.

Labels That Talk, from Kailua Hawaii, has come up with software that lets consumers print high-density bar codes on strips of paper that store recorded voice messages. Scan it with a handheld scanner and it plays back a message. The strip of paper you see in the picture can hold about eight kilobits, enough for a ten-second voice message, said Ken Berkun, president and founder.

Application of multi-criteria decision making to sustainable energy planning-A review S. D. Pohekar , and M. Ramachandran Birla Institute of Technology and Science (BITS), Pilani 333 031, India Received 1 December 2003;  accepted 19 December 2003.  Available online 31 January 2004. Abstract Multi-Criteria Decision Making (MCDM) techniques are gaining popularity in sustainable energy management. The techniques provide solutions to the problems involving conflicting and multiple objectives. Several methods based on weighted averages, priority setting, outranking, fuzzy principles and their combinations are employed for energy planning decisions. A review of more than 90 published papers is presented here to analyze the applicability of various methods discussed. A classification on application areas and the year of application is presented to highlight the trends. It is observed that Analytical Hierarchy Process is the most popular technique followed by outranking techniques PROMETHEE and ELECTRE. Validation of results with multiple methods, development of interactive decision support systems and application of fuzzy methods to tackle uncertainties in the data is observed in the published literature.

Meanwhile, it provides the latest market information for scrap metal, plastic scrap and waste paper every day; and updates on supply and demand including daily waste rubber, waste electronic/electric equipment, waste glass and waste leather.

this may make international news for south africa - the "europe of africa" - but it's commonplace in uganda. load-shedding? we don't have it for just a few hours in the afternoon, that would be luxury. no, load-shedding in uganda tends to be on a 24-hour-on-24-off cycle. yes, that means for 24 hours you have electricity, then for the next 24 you don't. there's some elaborate schedule for knowing when load-shedding's going to hit your part of town; sometimes the schedule gets printed in the paper and (almost) always it isn't followed.

With 5 million wind turbines needed (Stanford paper), asset management of renewable plant can only be a rising trend.

The Paper I submitted to the ECEEE Summer Study 2007.

In the past six months, flat-screen plasma televisions have accounted for nearly half of all TVs sold around the world. During the manufacturing process, plasma televisions release a gas called nitrogen trifluoride, or NF3, which does approximately 17,000 times more environmental damage than carbon dioxide. But because NF3 was not widely used when the Kyoto protocol was created, it is not classified and controlled as a harmful gas--so even though we've tightened the belt and reduced some emissions, we've missed new ones that are making things far worse.
