Designed by Carla Diana and Jeff Hoefs of Smart Design, the inlet outlet concept includes adapter kits that convert common household products into energy-generating devices compatible with the inlet outlets.Besides exercise equipment, sources of reusable energy could include things like a refrigerator or gas oven/range, which generate heat that could be captured by a panel and converted into electricity. In addition, motion is everywhere: a welcome mat that is constantly stepped on, an outdoor trampoline, and a flag in the wind all generate kinetic energy that could be converted into electricity and fed back into the grid through the inlet outlet. No matter how small, inlet energy could counteract some of the energy consumed.The designers hope that, if the inlet outlet plugs and adapters are easy to use, the system could encourage further development of household devices that can be used to generate electricity.The inlet outlet was just one of many innovative eco concepts at the competition, and didn’t make the top 10. Based on audience feedback and live judging, a concept called the Tweet-a-Watt – a power meter that wirelessly publishes your power usage on your Twitter page – won first place. The Power-Hog, a piggy bank that monitors power consumption, won second place.More information: Inlet Outlet concept pageTop 50 EntriesGreen Gadgets press release• Join PhysOrg.com on Facebook!• Follow PhysOrg.com on Twitter!© 2009 PhysOrg.com This document is subject to copyright.

Designing a crystallization chamber (PhysOrg.com) — Ever wish you could you power your home’s electrical appliances with the energy you generate on your exercise bike? A new concept called an “inlet outlet” could allow homeowners to put power from kinetic household activities – such as exercise equipment – back into the grid through a wall socket, helping to lower electricity bills. Basically, the inlet outlet would be the opposite of a typical wall outlet. The “inlet outlet” allows users to give power back to the grid to counteract energy consumption.

(PhysOrg.com) — The “Windy City” is about to make use of that natural source of power, thanks to the addition of an electric vehicle (EV) charging station. Last year, Chicago offered the first solar powered charging station, in an effort to create a situation in which the electricity being provided to plug in cars was clean. Now, Chicago offers the first wind powered EV charging station in the continental United States. (Hawaii has a wind powered EV charging station.) Image source: Coulomb Technologies The equipment is being provided by Coulomb Technologies, via its distributor Carbon Day Automotive. The wind power is actually coming from a local law firm. The law firm has a partnership with MC Squared Energy Services, and is sending some of the power to the charging station. The agreement uses energy from wind farms in Illinois. MC Squared provides clean energy to a number of commercial businesses.Going forward, Coulomb hopes to create an entire network of rapid-charging stations that could serve as places for electric vehicle drivers to get power for their plug-ins. This would work with all-electric vehicles or with plug-in hybrids. The idea is to assuage fears that electric vehicles don’t do much for the environment, since the electricity that powers them comes from fossil fuel sources. If, however, more EV charging stations offer power from clean sources, then it would enhance the overall “green-ness” of the power grid.

The team uses a “spectrally selective approach” with achievements that were first outlined in a paper published in Applied Physics Letters in 2011. They noted how previous efforts to construct semitransparent devices focused on the use of thin active layers (or spatially segmented films) with light absorption focused in the visible spectrum, and have been limited to either low efficiencies or low average visible-light transmissivity.They said that they demonstrated “heterojunction organic PV (OPV) cells utilizing a molecular organic donor, chloroaluminum phthalocyanine (ClAlPc), and a molecular acceptor, C60, that show peak-absorption in the ultraviolet and near-infrared (NIR) (wavelength span of λ = 650–850 nm).”They wrote that, in combining the OPVs with selective high-reflectivity near-infrared mirror coatings, “we optimize device performance while also permitting high transmission of visible photopic light through the entire device.”The paper, “Transparent, Near-Infrared Organic Photovoltaic Solar Cells for Window and Energy-Scavenging Applications,” is by Richard Lunt and Vladimir Bulovic. Both are cofounders; Lunt is an expert in organic and inorganic excitonic materials for solar energy and energy utilization efficiency. Spun out of the MIT lab of Prof. Bulović, the company’s work is still at the development stages. The focus is to improve the efficiency of the solar cells, according to Miles Barr, the president and CTO of Ubiquitous Energy. As reported in Technology Review, Barr is looking at ways to collect more light. Barr said the company is developing materials that gather energy deeper into the infrared.Last year, Barr made news as a recipient of the Lemelson-MIT Collegiate Student Prize for innovative solar technologies. His approach in fabricating solar cells on everyday surfaces was singled out, and its implications for the adoption of solar power. According to the MIT award announcement, “Barr’s approach, which enables solar cells to be printed directly on common materials like paper and textiles, could reduce the cost of solar energy by eliminating the need for specialized installation.” © 2013 Phys.org (Phys.org)—Can windows, tablets and e readers turn light into power? Can a surface coated with solar cells take sunlight and the glow of bulbs and change them into energy? As reported in Technology Review, expert scientists at a new startup called Ubiquitous Energy have those feats in mind. They want to develop transparent coatings and films that could harvest light energy when applied to buildings’ windows or mobile-device screens.

Earthworms can survive and recover after 3-week drought stress (Phys.org) —A combined team of researchers from the U.S. and China has found evidence to suggest that earthworms actually sequester more CO2 than they cause to be released into the atmosphere. In their paper published in the journal Nature Communications, the researchers describe experiments they conducted in a lab using two kinds of earthworms and various soil types in an attempt to discern how much CO2 they sequester. Explore further Earthworms. Credit: Photo courtesy of Cliff Johnston, Purdue University Department of Agronomy © 2013 Phys.org Scientists know that soil contains a lot of carbon, prior research has found that up to a fifth of all carbon emissions into the atmosphere come from common dirt. But it doesn’t happen spontaneously—earthworms and microbes break down leaves and other liter releasing the carbon in them. One recent study concluded after reviewing over 200 published studies, that earthworms alone are responsible for increasing the amount of carbon released from the soil by up to 33 percent. In this new effort, the research team suggests that earlier studies have not taken proper consideration of the amount of carbon that earthworms sequester.When earthworms eat liter that makes its way into the soil, some carbon is released right away—but not all of it, some is retained in the material that is eventually digested. Once digested that material is deposited back into the soil and cannot escape, which means it’s been sequestered by the worm. But because it’s a slow process, it’s not been studied very carefully. The researchers in this latest study set up soil in various states in a lab and then released two kinds of earthworms into most of them (some were left without worms to serve as a control) along with liter. They then let the samples sit for a month as they quietly monitored CO2 emissions.In analyzing the results, the researchers found that the worms caused the release of a lot of CO2 initially, but then things tapered off. They also found that the soil without the worms in it emitted just as much CO2 as that with it. And, there was no difference in emissions between the two types of earthworms. In analyzing the results, the team worked up a formula to separate out how much CO2 was being emitted and how much was being sequestered—their calculations showed that more of it was apparently being sequestered in the soil than was being released into the air.The team acknowledges that their findings are preliminary, and suggest that more research be conducted, especially over much longer periods of time. Their research has convinced them it might just turn out that earthworms are sequestering a lot more CO2 than they are causing to be released. This document is subject to copyright.

More information: Earthworms facilitate carbon sequestration through unequal amplification of carbon stabilization compared with mineralization, Nature Communications 4, Article number: 2576 DOI: 10.1038/ncomms3576AbstractA recent review concluded that earthworm presence increases CO2 emissions by 33% but does not affect soil organic carbon stocks. However, the findings are controversial and raise new questions. Here we hypothesize that neither an increase in CO2 emission nor in stabilized carbon would entirely reflect the earthworms’ contribution to net carbon sequestration. We show how two widespread earthworm invaders affect net carbon sequestration through impacts on the balance of carbon mineralization and carbon stabilization. Earthworms accelerate carbon activation and induce unequal amplification of carbon stabilization compared with carbon mineralization, which generates an earthworm-mediated ‘carbon trap’. We introduce the new concept of sequestration quotient to quantify the unequal processes. The patterns of CO2 emission and net carbon sequestration are predictable by comparing sequestration quotient values between treatments with and without earthworms. This study clarifies an ecological mechanism by which earthworms may regulate the terrestrial carbon sink.

The four-month Oz Fest, a showcase of Australian culture in India, kicked off with visiting Prime Minister Julia Gillard announcing the Ravi Shankar World Music Scholarship, named after the Indian sitar maestro, at Victoria University.Announcing the endowment Tuesday evening, Gillard said the scholarship will allow musicians to study at the Victoria University from 2013.‘This scholarship represents everything that India and Australia share. Ravi Shankar took Indian culture to the world,’ Gillard said at the opening of the Oz Fest from 16 October to 5 February. The festival opened with a fusion concert of Australian aboriginal music and a sitar recital by Anoushka Shankar, Ravi Shankar’s daughter, at the historic venue of the 16th century Purana Qila [Old Fort]. Also Read – ‘Playing Jojo was emotionally exhausting’Besides the Australian prime minister, the opening concert was attended by Indian Human Resource Development Minister Kapil Sibal, Australian envoy in India Peter Varghese and a host of dignitaries from Australia and India.Set against the backdrop of a small arched relic, the Sher Mandal Observatory, inside the Old Fort complex, the opening act left the audience gasping in delight. A spectacular light show highlighted the Islamic architecture and the intricate floral design — which was magnified on the red sandstone surface of the structure by a complex kaleidoscope of moving laser images and coloured 3D electronic lights. Also Read – Leslie doing new comedy special with NetflixThe light show, produced by the creators of Sydney’s Vivid Light Festival known for its light displays at the Sydney Opera House, was accompanied by a solo didgeridoo concert by virtuoso Mark Atkins. The didgeridoo is an ancient indigenous Australian drone instrument resembling a long wooden horn that produces a deep primal sounds like that of the gongs.It was followed by a solo concert of iconic Australian vocalist, Gurumul Yunupingu, a blind musician who sang about the ethnic myths, legends, spirits and cross-cultural connections. In 2011, he was named the most important voice from Australia by the Rolling Stones magazine. Gurumul’s plaintive voice spun a magical web on the sprawling heritage ambience.Twice Grammy Award-nominated Anoushka Shankar played two cheerful and rhythmic evening compositions, raga Tilang and raga Vachaspati created by her father Ravi Shankar and a Carnatic raga Adi.The festival is spread in four venues-Pune, Mumbai, New Delhi and Bangalore — with a panorama of music, performances, indigenous cricket, movies and art.
A home in Tibet is a beautiful tale of longing and love of a daughter for her mother. Tsering Wangmo Dhomoa, Tibet’s first poetess to be published in English wrote the book as a tribute to her deceased mother.After loosing her mother in a car accident on a highway in India, far from her country and her family, Tsering decided to take handful of ashes back to her mothers homeland to a nomadic village in East Tibet. The book is about her journey weaved with her mothers memories and their dreams; as they had only each other as family and refuge. Also Read – ‘Playing Jojo was emotionally exhausting’The launch and the first reading of the book took place in the Capital where book lovers from all age groups gathered to hear selected sections from the book by the author herself. Later, an interactive session took place between the author and the audience where she answered many queries related to the book and also shared her experiences about writing the book. ‘Though my mother is not alive but her absence is always lingering around me. It was her dream that someday I should publish a book,’ said Tsering.
2014 is here. Another year to fight, to forgive, to fall in love.1. LIVE AND LET LIVEMany a times we fail to do this. We try and squeeze in every little space. In the initial stage of any relation, constant togetherness feels like a bliss. But, as time passes we all feel suffocated with constant monitoring. Try your best to live and let live for a healthier and better tomorrow.2. RESPECTYourself and others. The more you do that, you will realise its importance. Relationships grow brighter only when two people respect each other. You get respect only when you generously give. Also Read – ‘Playing Jojo was emotionally exhausting’3. DON’T JUDGEWe land up judging others by the way we think. But, judging can lead to wrong decisions and prejudices that harm relationships and hurt us.4. TRANSPARENCYBe transparent to your world and yourself. This is one rule that will never let you down. Be honest to your loved ones and if you have to lie, don’t get caught. Lying is an art and you should learn to do it right.5. SMILEIt actually doesn’t cost a penny but yet we see faces that never smile! Smile is actually sets things right. Don’t forget to share smiles every day. Life is too short to be taken too seriously. Also Read – Leslie doing new comedy special with Netflix6. SPEND TIMENot only with your spouse or family but with yourself. Listen to your favourite music, watch some old movies or just catch up with your buddies. Sometimes, just forget that mobile phone, tab or and spend time learning yourself. You will feel brighter!7. SAVE AND SPENDSaving for future is very important. But, living life fully is equally vital. Do spend on little treats. Sometimes, just go for a spa session or plan a weekend getaway just to feel like a king. Life is unpredictable, enjoy it. Each day should be a celebration.8. SURPRISEYour partner in small little ways and gestures – may be the first cup of coffee to wake him/her or a perfect foot massage at the end of a busy, hectic day. Sometimes do plan small things to floor your partner. This will add a lot of spice to your togetherness. 9. PARENTSDo try and involve your parents along with your partner for some trips, outings or dinner at a restaurant. Parents never say it but feel really happy when you pay them attention. If all can be woven into one big family, the year will become more beautiful.10. SAY SORRY and THANK YOUDon’t hesitate or have any ego to say these. Small words or phrases, some things make a huge difference and can bridge the gaps miraculously. Not only to our own people but to anyone who deserves it, do say ‘sorry’ or ‘thank you’.11. DON’T TOLERATE…Everything and anything. Do express, do protest, do fight when you can’t take it anymore. Any situation that troubles you and makes you unhappy, face it and sort it. Be nice but don’t let your niceness be taken for granted.12. FALL IN LOVEAffairs might have shattered you. People might have betrayed you. Yet, don’t lose confidence on love. Love will surely paint your life when the time is right. Keep your eyes and heart open to receive love when it arrives.13. DELETESit back and delete all the phone numbers of those people who don’t exist in your life or bring back bad memories to you. Deleting numbers or deleting from the ‘friends list’ will give you a smile of victory. Just delete the trash, the unwanted.14. LEARN TO LOVE…Others for sure, but love yourself first. You are the VIP. Treat yourself the best and then the rest. In our lives, we always put us in the last list of priority and spend most of our lifespan living for others. Time to change that. Alphabetically, ‘I’ comes before ‘U’. So, let it be, ‘I Love I’ this new year!
Kolkata: In a desperate bid to arrest the kingpin of the racket that used to sell dead chicken, police conducted a raid in the house of Kaushar Dhali’s in-laws at Basirhat in North 24-Parganas on Sunday morning.Though the police didn’t find Kaushar there, the investigating officers have intensified the vigil to get hold of him as early as possible.A police officer said that Kaushar has fled along with all members of his family. The house was found locked and it is suspected that he has taken shelter in the house of one of his friends or relatives. Also Read – Heavy rain hits traffic, flightsSources said that the police conducted raid in the house of Kaushar’s in-laws as he had been hiding there for the past one or two days. However, he had somehow managed to flee from the house before police raided the place.Police came to know that Kaushar had gone to Basirhat to stay for a few days and he had made the plan to flee, realising that the police would conduct raid there. The police have also found his house at Lake Town locked from the outside. They have intensified vigil in and around Rajarhat and New Town area, so that he cannot flee from the place without getting arrested. Kaushar is originally a resident of Basirhat. He owned a chicken farm at New Town, where the police had raided and found two freezers packed with carcass meat. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedThe police had come to know about the chicken farm when it raided a restaurant near the airport. They found frozen meat in the restaurant and enquired from whom they used to procure the same. Subsequently, the authorities of the restaurant took the police to the chicken farm.Police had found several dead chickens in the farm. The farm was sealed and some were also arrested in this connection. Kaushar had, however, managed to flee from the place. The police had then initiated a search for Kaushar. Investigating officers are not ruling out the possibility of Kaushar fleeing to some other state. They have questioned some of the people who were known to him, to ascertain the location where Kaushar is hiding. Meanwhile, the administration is taking steps to install CCTV cameras for surveillance in dumping grounds. Already, Rajpur-Sonarpur Municipality authorities have installed two CCTV cameras in a dumping ground. One more CCTV camera will be installed soon. The footages of the cameras will be monitored from the office of the municipality.
