Don’t phase out kerosene

Filed under: solar lighting — Tags: , — solaroutdoorlight @ 8:50 am

Indian scientists who have developed an improved lantern that uses kerosene have advised the government not to phase out the poor man’s fuel on environmental grounds.

Kerosene was traditionally burned in rural homes in hurricane lamps to provide lighting or in pressure stoves to cook food.

Now the Nimbkar Agricultural Research Institute (NARI) at Phaltan in Maharashtra has developed a device that simultaneously provides light (equivalent to that from a 300 watt electric bulb) and cooks a complete meal (including chapattis) for a family of five.

The lanstove (combined lantern and cooking stove) thus makes kerosene an ideal fuel for rural households, says Anil Rajvanshi, an IIT graduate and NARI director.

He says it is unfortunate that the Indian government has decided to phase out kerosene as a result of tremendous tirade by the Western countries against the use of kerosene from a climate change point of view. This move, he says, will deprive the poor people in India of a convenient household fuel.

According to Rajvanshi, it is the way in which a fuel is burnt that makes it clean or dirty. Liquid petroleum gas (LPG) and compressed natural gas become clean fuels only because of excellent combustion technologies available.

No doubt hurricane lantern is an inefficient and unclean combustion device,How does a solar charger work and where would you use a solar charger? says Rajvanshi.

Lanstove was developed by his institute precisely to overcome these drawbacks, he says in a report published in the latest issue of “current science.”

The research led to the device that burns kerosene efficiently and without causing any pollution.We have a great selection of blown glass backyard solar landscape lights and solar garden light.

Lanstove has been tested for the last eight months in 25 rural huts in western Maharashtra which do not have electricity. The users found that it is smokeless unlike the existing biomass-powered chulha, and gives excellent light compared to the presently used hurricane lanterns.

The levels of harmful carbon monoxide from these lanstoves are less than three parts per million whereas those from regular chulhas are 80 to 130 times more, according to the study.

“Thus the lanstove is an extremely clean device and equivalent to the LPG stove,” Rajvanshi told IANS.

The lanstove has been designed so that kerosene is pressurized and stored in a small separate cylinder from where it flows into the combustor and burns cleanly just like in the LPG cookstove.

This detachable cylinder can be filled up in kerosene dispensing shops,We installed flexible LED Strip lighting in our kitchen for under cabinet and within cabinet lighting. the same way an LPG cylinder is now charged.

However, despite its advantages to the people in India’s rural areas, the lanstove cannot be introduced at present on a large scale because of unavailability of kerosene, Rajvanshi says.

Today, below poverty line (BPL) families get only five litres of kerosene per household every month whereas lanstove users need at least 15-20 litres of kerosene per month. What is therefore needed is an enlightened policy that makes at least this much kerosene available to rural poor at subsidised price, the NARI report says.

Rajvanshi points out that around 300 million Indians are without electricity. Solar- powered light emitting diode (LED) lanterns promoted by various agencies and also government departments are not only costly and difficult to maintain but the LED light has recently been shown to be harmful to the eyes producing irreparable damage to the retina. “Besides, unlike lanstoves, these solar lanterns cannot cook,” he says.

Although kerosene is a fossil fuel, there are extensive efforts currently the world over to produce kerosene-like fuel from agricultural residues so as to make it renewable, says Rajvanshi. “I hope these efforts are also undertaken in India which has a huge amount of agricultural residues.”

All his life Mahatma Gandhi studied and wrote under the light of kerosene hurricane lanterns and he also used to apply kerosene to his body as a mosquito repellent, says Rajvanshi. “I am sure that if he were alive today, he would have wholeheartedly embraced the lanstove and promoted its use among the rural poor.”

Trina Solar was selected to supply multicrystalline silicon modules for Sempra Energy’s 345-megawatt Copper Mountain 3 project — and that could be a signal that PV module prices are flattening.

“The lowest prices for modules have been in the large-scale utility projects,” Trina Americas President Mark Mendenhall explained. “We didn’t participate a lot. We felt we could give up share in that segment until the market stabilized.”

Trina has been focused on the residential and commercial segments. “There was a gap in the relative costs,” Mendenhall said, “that made thin film and other technologies more competitive in utility-scale solar.”

But today’s low silicon module prices make balance-of-system costs more significant than module costs. “The value of our multicrystalline PV efficiency became more important,” Mendenhall said. “And the number of gigawatts we have installed has reduced the perceived risk and increased the financeability of a project with our technology.”

Also, he added, consolidation has left fewer manufacturers capable of providing the 1.1 million high-quality modules needed by AMEC, the Copper Mountain EPC provider. The module order must be met for the Q1 2015 construction completion target to fulfill Sempra’s contracts with the Los Angeles Department of Water and Power and the City of Burbank.

Billboards on road

Filed under: LED Work Lights — Tags: , — solaroutdoorlight @ 8:49 am

“Five years ago when it rained constantly for 10 hours, a motorcyclist took shelter from rain under a billboard.We carry a extensive line of Parking Lot Lighting inventory. It fell down on him and a few other people who had gathered under it,” recalls Amber Alibhai, a representative of Shehri a not-for-profit organisation which looks into civic problems facing the city. The misery caused by the recent rains in Karachi would have multiplied if these billboards had fallen down.

“In no civilised city are billboards placed on main roads. Not only are they a traffic distraction but also a threat to life if they fall down during a storm or heavy downpour,” she adds.An emergency light is a battery-backed lighting device that comes on automatically when a building experiences a power outage.

At the Ayesha Bawany School on Sharea Faisal putting up a 90-foot tall bill board on the rooftop caused quite a stir among the parents who considered it to be a threat to the life of their children. “What if it fell down on the head of a student?” claimed an anxious parent. The school already has two tall billboards perched at its rooftop. They belong to a brand of paint, which the school spokesperson claims, is owned by the owners.

“The school does not get paid for the two billboards, the paint brand belongs to the school owners,” he said, adding that work for the third billboard came to a halt after the cantonment board ordered against it.

At many places in Gulshan and NIPA, trees have been chopped to make way for billboards.

“From Hasan Square to the bus stand near my house, I used to walk under the shady trees which took up the entire service lane. Recently they have been chopped off and billboards have been placed there instead,” complained Fauzia Ali, a student at Karachi University.

Until recently huge billboards had been erected at the Kothari Parade, which had hid the fa?ade of the beautiful heritage site. Billboards with moving objects such as flash lights are a distraction, drivers claim. Opposite the Regent Plaza on Sharea Faisal, a washing powder company had placed a billboard with the flashing outlines of a water tub. “Sometimes I got so engrossed in looking at it that I missed vehicles,” said Aftab Ahmed, who drives from Saddar to PECHS everyday.

The Karachi Metropolitan Corporation (KMC) has a strict size for billboards. In a pre-monsoon meeting held by former KMC administrator Hashim Raza Zaidi, directives to fix the billboards were given.

“Advertising devices, including billboards, should be installed in such a manner that their size and height doesn’t affect the traffic on roads and corridors and also do not cause accidents,” he had said.

But nothing happened after it. There is no controlling authority to keep a check on billboards in Karachi. It is distributed among the KMC, cantonment boards and the Karachi Development Authority. And that explains the different sizes of billboards spread all over the city. “Each body all has its own rules,” claims Alibhai.

WYNDHAM Vacation Resorts Coffs Harbour is the only Australian finalist in the prestigious “Go Green Awards” which recognise resorts that demonstrate extensive environmental initiatives.

Since placing third in the awards in 2010 Wyndham Coffs Harbour- Treetops has implemented a host of green initiatives, making it a strong contender for this year’s top prize.

The property is now at stage three of its LED lighting upgrades, taking the resort to 50% LED lighting. A second 10Kw solar system was installed this year to reduce energy consumption. Eight new speed controlled pool pumps have also been implemented, leading to an impressive 85% reduction in power costs in the resort’s pump room.

Together these initiatives have seen on average, a consistent 15% reduction in overall power usage.

The resort generates its own fertilizer for its extensive gardens, using a small tractor, a chipper-shredder and two bays for green waste and mulch.

An onsite worm farm assists the process, and is also used to dispose of food scraps. A new program is currently being developed which will also allow guests to contribute to the worm farm.

Apartments feature recycling bins,A solar bulb that charges up during the day and lights the night when the sun sets. water efficient washing machines and dishwashers and environmentally friendly taps and shower heads, while rainwater tanks are used for irrigation on the property.

Children at the resort are encouraged to learn about the environment, with each young guest receiving a “Wynnie and Friends” Adventure pack which includes games and educational material.

The childrens’ characters were developed as part of the highly-successful, companywide Wyndham Green program, which aims to conserve resources, preserve natural habitats and prevent pollution.

Until recently, both Herman Wallace and Albert Woodfox had been held in solitary confinement for 4 decades in Louisiana – longer than almost any other known prisoner in recent U.S. history. It’s long enough for one’s body to forget it ever knew anything else but four white walls and for the mind to be reshaped by extreme isolation. Juan Mendez, the United Nations Special Rapporteur on Torture, says that after 15 days, further isolation can cause permanent psychological damage and constitute torture.

Herman has just been diagnosed with stage 5 liver cancer. Unless Governor Bobby Jindal of Louisiana grants him clemency, he may likely die in prison.

After decades in isolation, people experience hyper-anxiety, paranoia, insomnia, hallucinations,A solar bulb that charges up during the day and lights the night when the sun sets. emotional detachment, panic attacks and uncontrollable rage. Many start fights with guards just for human contact. Others cut themselves just to be taken out of their cells for a few days in the prison hospital.

I spent over a year in solitary confinement when I was held as a political hostage by the Iranian government from 2009 to 10. I experienced all of these reactions at various times throughout my isolation. In some cases, these symptoms have increased since my release. Almost three years later, I am still trying to shake the mental damage and loss that was inflicted upon me during those 410 days.

After spending nearly 41 years in a cramped cell, the cancer diagnosis led prison officials in July to transfer 71-year-old Herman to a ten-bunk prison dorm.An emergency light is a battery-backed lighting device that comes on automatically when a building experiences a power outage.

He can now open a door,” says Marina Drummer, who has been advocating on his behalf for the past 15 years. “He can walk from the dorm room into the dayroom without being shackled.”

After spending 23 hours a day isolated in a small cell akin to a coffin, this change is monumental.

In 1972, Albert and Herman, two young black men, were charged and convicted of the murder of prison guard Brent Miller, despite the fact that no DNA evidence linked them to the crime. They were locked in solitary: 23 hours a day alone in a small cell, and were denied any meaningful review of their continued isolation.

In the decades after the trial, significant flaws in the legal process have come to light. Evidence suggests that the key eye-witness was bribed by prison officials into giving statements against the men and that the state withheld evidence that pointed to Herman and Albert’s innocence. Potentially exculpatory evidence mysteriously went “missing” before the trial and more witnesses later recanted their testimony.

After Herman’s diagnosis became known, human rights groups around the country – most notably Amnesty International – have called for his release on compassionate and medical grounds. More than 46,000 people in the U.S. have called on Governor Jindal to release Herman Wallace in the months since his diagnosis; tens of thousands of appeals have also poured in from around the world.

Herman is not a dangerous criminal – he is a 71-year-old cancer patient who has already survived an unthinkable nightmare. His continued imprisonment serves no purpose: prison records demonstrate that he is no threat to himself or others. As his conviction continues to be challenged before the courts, his cancerous tumor continues to grow. Despite treatment, he does not have much time left.

I recently turned 35. Herman Wallace has survived more years being psychologically tortured in our prisons than I’ve even been alive. I think about him still waking up every morning, tired and sick,We turn your dark into light courtesy of our brilliant sun, solar street light, solar power generation. but still fighting for his life and his long-deserved freedom. As Herman’s health fails, we have to fight for him – and there’s not much time left.
