The content is provided for information purposes only. In an exclusive interview with John Bryson, Chairman and CEO of Edison International by CNBC reporter, Dylan Ratigan explained a new direct method of delivering solar energy. The process is called Photovoltaic technology,which means it converts sun energy directly into power within the solar cell. The unique aspect of this project, as explained by John Bryon involves leasing about 2 ½ miles of rooftops in the hotter regions of Southern California. The roof tops will be fitted with thin-film solar cells and have the ability to literally dump electricity into the surrounding community. The communities have been preselected to include areas where Southern California Edison has a growing customer base. The advantage of the photovoltaic technology is that it does not require a separate transmission station or added fuel costs. The thin-cell solar manufacturers has not been determined at this time.According to Mr. Bryson, the Photovoltaic Roof Top Project is planning to be up and running in its initial phase by this Summer. The process when it begins can almost immediately begin to produce electricity to relieve the additional burden of air conditioning and the like during the hot season. The cost of the project is estimated to be 875 million dollars. The advantage to Edison and its customers is the ability to eventually according to large scale production reduce the cost of energy. Mr. Bryson estimates the new technology on a large scale is cost effective because other methods like natural gas, coal and hydro sources require additional expenditures for transmission and fuel. The State of California is at the forefront of legislation concerning alternative energy sources and has set a mandate that 20 percent of all electricity must be generated by alternative energy sources by 2010. According to Mr. Bryson, Edison International and its subsidiaries are in complete accord with energy conservation. Edison International , local economies, customers and manufacturers may see big dividends in the future for their investment in energy conservation. The project is the single largest solar energy project of its kind on a world-wide basis.

The process requires no fuel or a transmission station to operate. The plans include an initial phase to be up and running by Summer, 2008. center_img Citation: Edison International In Process of Launching Photovoltaic Project on Roof Tops (2008, March 28) retrieved 18 August 2019 from https://phys.org/news/2008-03-edison-international-photovoltaic-roof-tops.html Explore furtherlast_img read more

New invisibility cloak allows object to see out through the cloak

first_img(PhysOrg.com) — “Many groups have been working devices that make objects invisible,” Che Ting Chan tells PhysOrg.com. “Most of these devices, however, encompass the object to be cloaked.” Chan, a scientist at The Hong Kong University of Science and Technology, believes that it is possible to create a cloaking device that would be able to render an object invisible without encompassing it. “With the devices that encompass the object,” Chan continues, “the cloaked subject is ‘blind’. It can’t ‘see’ out through the cloak. We can’t see the object, but the object can’t see us, either. We wanted to create a conceptual design that would let the object ‘see’ out through the cloak while hiding it from sight.” Along with Yun Lai, Huanyang Chen and Zhao-Qing Zhang, Chan believes that this could be accomplished. Their ideas are published in Physical Review Letters: “Complementary Media Invisibility Cloak that Cloaks Objects at a Distance Outside the Cloaking Shell.”Right now, such a device exists only theory. “We haven’t built the device,” Chan says, “but we have shown mathematically how it could work. It is a very specific description of the materials needed. If you have the time and resources, we think it could be done.” He points out that it might have interesting possibilities in a number of fields where invisibility might be desirable. Theoretically, a device such as Chan suggests, would work through complementary media. “Our strategy is to put the cloaking device and the object to be cloak next to each other. The cloaking device is a kind of anti-object. The way the light is gathered and scattered by the two objects – the cloaking device and the object it is making invisible – would cancel each other out.” Chan continues by explaining that the cloaking device would become invisible as well. “Both must be invisible in order for this to be effective, and I think we have shown in theory how this could work.”Chan admits that 100 percent invisibility is only available for one wavelength, however. “Right now, the usefulness, especially for military applications, is limited,” he says. “You can only make the object invisible in one wavelength, so if I made it invisible for the visible spectrum, all someone would have to do is use radar to detect the object. A lot of work would need to be done to make a cloaking device that worked for more wavelengths.” He pauses, before adding, “It might be possible to make the object almost invisible for broader wavelengths, but that would also take a lot of work. And you still wouldn’t have 100 percent visibility.”The Hong Kong team, although interested in rendering objects invisible, is working on another ambitious project. “We have shown that we can cause invisibility in objects, and allow them to ‘see’ out of the cloak,” he says. “We are now working on how to transform how an object looks. Invisibility was just the first step in this. By understanding how complementary media invisibility might work, we can also look at how it might be possible to transform the look of an object into something else. Perhaps make an apple look like a banana.”Science is beginning to sound more like magic by the day.More information: Yun Lai, Huanyang Chen, Zhao-Qing Zhang, and C. T.

The researchers found that the microbots can remove 95% of the lead in polluted water in one hour, and can be reused multiple times, potentially offering a more effective and economical way to remove heavy metals than previous methods. Microbots individually controlled using ‘mini force fields’ More information: Diana Vilela, et al. “Graphene-Based Microbots for Toxic Heavy Metal Removal and Recovery from Water.” Nano Letters.

Credit: Vilela, et al. ©2016 American Chemical Society Journal information: Nano Letters The researchers, Diana Vilela, et al., have published a paper on the lead-adsorbing microbots in a recent issue of Nano Letters.”This work is a step toward the development of smart remediation system where we can target and remove traces of pollutant without producing an additional contamination,” coauthor Samuel Sánchez, at the Max-Planck Institute for Intelligent Systems in Stuttgart, Germany; the Institute for Bioengineering of Catalonia in Barcelona; and the Catalan Institution for Research and Advanced Studies in Barcelona, told Phys.org.Heavy metal pollution in water is a common problem stemming from industrial activities, including the manufacturing of batteries and electronics, as well as mining and electroplating. These activities produce metals such as lead, arsenic, mercury, cadmium, and chromium, all of which pose a safety hazard to living organisms and the environment.In the new study, the researchers focused specifically on removing lead from wastewater by designing tube-shaped microbots with three functional layers. The outer layer of graphene oxide adsorbs the lead from the water. The middle layer, nickel, makes the microbots ferromagnetic so that their direction of motion can be controlled by an external magnetic field. The inner layer, platinum, gives the microbots the ability to self-propel themselves through water. When hydrogen peroxide is added to the wastewater, the platinum decomposes the hydrogen peroxide into water and oxygen microbubbles, and ejecting the microbubbles from the back of the microbot propels it forward. Play Magnetic guidance of a microbot. Credit: Vilela, et al. ©2016 American Chemical Society When the microbots are finished adsorbing the lead, a magnetic field can be used to collect them all from the water. Then the microbots are treated in an acidic solution to remove the lead ions, which can later be recovered and reused. The microbots can also be reused for further lead clean-up. “This is a new application of smart nanodevices for environmental applications,” Sánchez said. “The use of self-powered nanomachines that can capture heavy metals from contaminated solutions, transport them to desired places and even release them for ‘closing the loop’—that is a proof-of-concept towards industrial applications.”In the future, the microbots could even be controlled by an automated system that magnetically guides the swarm to accomplish various tasks. “We plan to extend the microbots to other contaminants, and also importantly reduce the fabrication costs and mass-produce them,” Sánchez said.The combination of self-propelled robots with functional layers also opens the doors for similar designs that could have applications in areas including drug delivery and sensing. © 2016 Phys.orglast_img read more

Costco Opens In Shanghai Shuts Early Owing To

first_img by NPR News Merrit Kennedy 8.28.19 4:03pm It looks like Costco is a hit in Shanghai. On Tuesday, the U.S. wholesale chain opened its first location in mainland China and was so inundated with eager shoppers that the store closed early owing to “security concerns.”The next day, Costco began limiting the number of shoppers in its warehouse to 2,000 at a time. “Local police will assist in improving traffic in the area, in order to lessen the disturbance to our neighbors, and we have improved our internal guest flow system,” the company said in a statement on the social media platform WeChat.Costco said that in the coming week, people who have memberships to the store will be notified “if we are nearing maximum capacity or if there are long wait times.”Photos from the store opening show long lines of customers queued up to apply for membership and crowds of people surrounding a roast chicken counter and freezers full of meat.The company, which first opened in the U.S. in 1976 under a different name, offers its members bulk items at wholesale prices. The cavernous stores are known for vast shelves with items stacked nearly to the ceiling.According to the Chinese news agency Xinhua, membership to the Shanghai store costs about $42 annually. “Prices of general merchandise in Costco are 30 to 60 percent lower than market prices and the food sold there is 10 to 20 percent cheaper,” Xinhua noted.The low prices certainly created a commotion, with checkout lines two hours long and three-hour waits simply to find a spot in the parking lot.It’s worth noting that some major international brands have had a hard time in China. As Bloomberg reported, “Carrefour SA sold an 80% stake in its China unit at a discount in June while German wholesaler Metro AG is looking to sell its operations.”Sam’s Club, the Walmart-owned rival wholesaler, has had a presence in the Chinese market for more than 20 years. It currently has at least 23 locations there.Costco’s senior vice president for Asia, Richard Zhang, told AFP that the Chinese consumer’s familiarity with Sam’s Club could help his company. “Chinese consumers are ready to pay for a membership card that grants them an exclusive privilege to buy at a warehouse store, it’s not a new concept in the country,” he said.Still, the ongoing U.S.-China trade war could complicate the company’s supply. Zhang told the wire service that about 50 percent of the products are from overseas and that some fresh produce items from the U.S. have been replaced with items from Australia.Copyright 2019 NPR.

Traditional tastes

first_imgThere are many restaurants to please the Punjabi palette in the Capital, but then there are also classics. Nestled in the post Chanakyapuri locale, we took time to check out Garam Masala, a part of the Forte Grand complex. The complex has the restrobar Garam Masala, a kebab and grill lounge Pepper and a banquet hall as well. The enclosed space is also perfect for out-door parties if the weather is right. But in the terrible Delhi humidity and heat, the AC interiors worked best. Also Read – ‘Playing Jojo was emotionally exhausting’Garam Masala can be described as the perfect family restaurant, it has very comfortable seating arrangements that provide the right amount of comfort and privacy. If you want to take your family out for a nice meal, this is it!Serving a great variety of Indian dishes, the restaurant also holds its own with some Chinese options. The kebabs are a must try, we suggest the chicken tikkas which were quite perfect. If you want something else as well – the dry chilli chicken is what you can pick. They also have a great fish tandoori. Also Read – Leslie doing new comedy special with NetflixOf the Indian breads the Lal Mirch Parantha was very well made and it went perfectly with the dal makhni. The parantha is a must try, it is light, flaky and not as spicy as it looks. We have always been a little partial about restaurants that make their dals well and Garam Masala is definitely one of the places that do.What you definitely must not miss are the desserts. Garam Masala dishes out some great Indian deserts like the ever-favourite gulab jamun, rasmalai and the moong ka halwa. After a scrumptious Indian meal, nothing goes better than a nice cold piece of rasmalai. The place also has a very well stocked bar so pick your poison with the meal. A meal for two comes to about Rs 1200 (without taxes and alcohol). Great location, great food and some very comfortable time out – head over.last_img read more

ADDA launches mobile application to smoothen tax payment process

first_imgDurgapur: Asansol Durgapur Development Authority (ADDA) has set December 2018 as the target to integrate its entire leased out land into its online payment gateway service.”We have prepared a legacy data of these leaseholders after a lot of hard work. There are around 3,000 such leaseholders, whose tax payments are irregular. Once we integrate them in this online payment gateway, we will be able to keep them updated about their dues and the pending rent can be mopped up easily,” ADDA CEO Arun Prasad said on the sidelines of the launch of a mobile application for both Android and iOS users, for online payment gateway service.The ADDA Online app service was formally launched by its chairman Tapas Banerjee at its office in Durgapur on Monday.It may be mentioned that out of the leased out land belonging to ADDA, 80 percent is residential, 15 percent is commercial and 5 percent is industrial.”We have already prepared a database of shops and have started the process of registering them under ADDA Online. They will be soon getting alerts of the pending amount and the time period they need to clear their dues. They can pay online or can deposit the amount with a private bank with which we have tied up. Soon, we will tie up with some nationalised banks too,” Banerjee said.A workshop will be held on Wednesday with around 150 shop owners, who will be registered on the online plat-form.ADDA, which launched the online platform in June last year, has mopped up Rs 12.5 crore till date and now, with the launch of mobile payment gateway and integratingshops and hawkers and then the land leaseholders, is hopeful of earning a revenue of around Rs 25 crore by June 2019.Most of these shop owners would visit the ADDA office once in three months, collect details of payments and then clear the dues. Delayed payments had become a cause of worry.The online payment gateway for collection of various fees like developmentcharges, water charges, mortgage fees, transfer fees and ground rent, among others, have relieved the residents from the hassle of travelling to the ADDA office.ADDA covers an extensive area of 1,603 square km, comprising two municipal corporations and eight development blocks.last_img read more

Message of harmony the spirit of Martyrs Day rally

first_imgKolkata: “Ekotai Sampriti” became an integral part of the Martyrs’ Day rally on Saturday with people from across the state coming in with placards and posters spreading the message of communal peace and harmony.This comes when TMC supremo Mamata Banerjee had been repeatedly saying that Bengal has the rich heritage of communal harmony. With her repeated pleas, she has urged the masses not to indulge in any sort of instigation and not to pay any attention to rumours. Also Read – Rain batters Kolkata, cripples normal lifeThe move of the Trinamool Congress workers and supporters in spreading the message of peace and harmony during the Martyrs’ Day rally earned significance when there had been repeated attempts by communal forces to disturb the same in the state.People had started turning up to the city from Tuesday onwards to attend the mass rally and to listen to the party supremo, who played a key role in keeping up the tradition of the communal harmony in Bengal. Besides making people aware, the Chief Minister also requested them to inform the police as soon as they realise that there is some issue and there are deliberate attempts to cause trouble. She also directed the police to maintain a strict vigil. The police also carried out awareness campaigns through social networking sites as well in this connection. The theme of the tableau of the Mamata Banerjee government at the Republic Day parade also highlighted the same sentiment of Ekotai Sampriti.

India suffer 03 loss against Iran

first_imgIndia on Tuesday slumped to their third successive loss in the 2018 FIFA World Cup qualfiers as they suffered a 0-3 thrashing at the hands of mighty Iran in a group match here.Lacking in international exposure and vastly inferior in technique as compared to their more fancied rivals, the Indians put up a gritty fight in the first half but broke down later by conceding two quick goals in the early part of the second session in the Group D match at Kanteerava Stadium.

The Indians could string together very few threatening moves and they had to deseperately defend their citadel for most part of the match.To be fair to the Indians, who are ranked 155th in the FIFA charts as against the visting side’s 40th, maintained the shape in defence to deny the Iranians’ incessant attack for a large part of the match. With the loss , India are yet to open their account in the qualifying round. They have lost to Oman and Guam in their earlier matches. Iran, on the other hand, jumped to the top of the group with seven points from three matches.last_img read more
