Govt bans import of CNG cylinders, conversion kits

Posted on December 16, 2011. Filed under: Natural Gas, Pakistan |

ISLAMABAD: The Economic Coordination Committee (ECC) of the cabinet has approved a ban on the import of CNG cylinders and conversion kits in the wake of the current gas shortage in the country.
The ECC which met here on Thursday with Minister for Finance and Economic Affairs Dr Abdul Hafeez Shaikh in the chair also banned installation of new CNG kits in vehicles.
The existing stock and its owners shall be allowed to use their kits and cylinders, and no new licence shall be issued in this regard, the ECC decided. In the same way, CNG-fitted public transport vehicles i.e. buses/vans are exempted from this moratorium.
The ECC reviewed its previous proposal of monthly natural gas load management programme (winter 2011) on the SNGPL system, and decided to withdraw the previous approval of supply of 76 MMCFD gas to IPPs because of severe shortage of gas in the coming months and to enhance the gas supply to fertiliser plants.
The ECC also approved the summary “energy efficiency audit of fertiliser plants” and “ban of POL products export to Afghanistan and Central Asian Republics” (CARs), proposed by the Ministry of Petroleum and Natural Resources.
The committee was informed that the actual condition is quite different as this import is being practiced only on paper and all these POL products are being sold here in Pakistan after going through the export process.
The ECC also decided that purchase of 200,000 tones of sugar will be re-tendered with certain modifications in the tender terms and conditions. Prior to this decision, the committee reviewed the sugar situation in the country and discussed in detail the proposal to purchase 200,000 tons of sugar from domestic sugar mills.
The finance minister appreciated the sub-committee’s effort in lowering the sugar pricefrom Rs63 to Rs53.73 on December 12. The committee directed the TCP to issue a gallop tender and finalise the process within the coming 10 to 12 days.
The ECC was of the opinion that previously blacklisted sugar mills will also be allowed to bid in this tender provided they deposit the penalty to the TCP. The committee discussed proposal of the Ministry of Industries for import of urea for the Rabi season 2011-12.
The ministry informed the ECC that import requirements of urea are 700,000 tones to meet overall demand of 3,400,000 tones, in which 200,000 tons have already been allowed. The petroleum minister added that import requirements of urea would increase further due to short supply of natural gas in the coming two months. The ECC discussed the proposal at length and decided to meet the remaining shortage of urea for Rabi 2011-12.
The finance minister being the chairman of the ECC enquired from the committee members about formula on the basis of which gas is provided to fertiliser plants, and took exception that despite provision of gas to certain plants they do not lower the prices of their products.
The minister also expressed concern on the pricing regime and subsidy provision and decided that a proper distribution mechanism be identified, and in this regard formed a committee headed by the petroleum minister and comprising secretaries of Water of Power, Production, Finance, Food, Industries and Planning Commission deputy chairman, to deal with fertiliser companies for fixing the urea price. The committee will report to the ECC in three to four days.
The committee also deliberated upon the distribution of available and imported urea, and directed the concerned ministry to ensure the pricing regime for the commodity.

Solar Water Filter – Innovation In Evolution

As they say, without possibilities, there is no creativity. So one thing is for sure, there are endless possibilities but only if we can dig them out. Reducing complexity is simplicity, and simplicity is creativity. Creativity has no boundaries and relies mostly on common sense which is rarely common. But those who are blessed use it to the best. Here is an example of a designer making a Solar Water Filter.

Solar Water Filter

Gabriele Diamanti has worked on a prototype for a solar powered water filter that comes under appropriate technologies category. The invention is called Eliodomestico which intends to bring safe drinking model to the families in the developing countries at no operating cost. The concept filter is made from cheap and widely available material with simple technological innovation. It’s made from terracotta, recycled plastic and anodized zinc and can deliver 5 liters of fresh drinking water every day and is expected to be an open project, thanks to the concept of open source.

The distiller is easy to use: in the morning fill the water tank with water from a local source and in the evening collect clean, evaporated and re-condensed water in a portable basin placed underneath the tank. The project is still a prototype with aims for being replicated widely globally through its open adaptation policy.

Hazards of energy savers

Posted on December 15, 2011. Filed under: Pakistan, Uncategorized |

THE energy crisis in our country has taken us towards the energy conservation these days at the national level. The use of energysaver bulbs instead of traditional bulbs and tubelights has increased throughout the country.

As everyone knows that energy-saver bulbs are economical in use but nobody knows that these energy savers can be a serious health hazard. A few months ago, in one of the newspapers I have noticed an awareness message published by Enercon (The NationalEnergy Conservation Centre) with the title `Energy saver bulbs have one hitch: toxic mercury`. I was greatly surprised because I was not aware that these saver bulbs can be dangerous to health if broken. The Enercon said if the energy saver bulb is broken, the room should be evacuatedfor atleastfifteen minutes. The low energy bulbs contains mercury (poisonous) which can cause migraine disorientation, imbalances and other health problems. When inhaled, it can cause allergies, severe skinconditions and other diseases.

Some precautions were also mentioned in case an energy-saver bulb is shattered, e.g., to leave the room, and not to use vacuum cleaner because it will spread toxic mercury around.

They should be cleaned after wearing rubber gloves and placed in sealed plastic bag. The trash of the remains should not to be thrown in a dustbin.

This is another issue that even in Islamabad no separate bins have been provided near residentialareas to dump toxic materials like batteries, remains of broken thermometers, blood-pressure instruments, etc.

The awareness message also mentioned warnings for the manufacturers to label their bulbs for safe disposal which should be observed on energy-saver packs.

I appreciate the efforts of the Enercon for providing information to the public. However, more should be done for their safe disposal.

Demos against fuel surcharge

Posted on December 15, 2011. Filed under: NEPRA, Tariff, Wapda / KESC |

LAHORE, Dec 13: Protests against imposition and recovery of fuel adjustment surcharge through electricity bills were reported from Multan Road and Defence areas on Tuesday with no loss of property or life.

Consumers in both the areas gathered at the local offices of the Lahore Electric Supply Company (Lesco) and wanted getting the surcharge deducted from their bills.

However, the Lesco employees refused to oblige them this time, triggering protests by those who had gathered there.

`Problem with the people is that they think that court`s stay order in their favour has been extended which was basically for industrial consumers and not for domesticones who are trying to avoid payment,` says a Lesco official.

He said they (Lesco officials) also had this confusion and they temporarily deducted the surcharges last month.

This month, the government had told the company to recover the surcharge, and the company had included the surcharge in the bills, he added.`What is hurting the people more and makes the fuel adjustment surcharge look exceptionally inflated is the fact that the actual bill is very low in the winter,` says another Lesco employee.

`Now, the bills make a horrendous reading: a bill of say Rs1,000 carries Rs2,000 fuel adjustment surcharge. These charges belong to the months of June and July when consumption of electricity units touches its peak. The bill-fuel charges equation is lopsided and hurting people more than anything else,` he said.

`This is sheer dishonesty on the part of the government; it has divided electricity tariff in many parts regular tariff, government duties and fuel adjustment surcharge,` said a man who participated in the protest in Defence.

`When the government talks about tariff, it only talks about regular head of tariff, which is a partial part of total charges. Taxes and fuel adjustment surcharge are exorbitant but not part of the tariff. It is what hurts consumers and hurts beyond tolerance, he said.

جرمنی: دنیا کا سب سے چھوٹا سٹیم انجن

Posted on December 15, 2011. Filed under: Global |

آخری وقت اشاعت:  منگل 13 دسمبر 2011 ,‭ 13:52 GMT 18:52 PST

جرمنی میں سائنسدانوں نے دنیا کا سب سے چھوٹا سٹیم (بھاپ) سے چلنے والا انجن بنانے کا دعویٰ کیا ہے۔

خوردبینی جسامت کا یہ ماڈل رابرٹ سٹرلنگ کے ایک سو پچانوے سال پرانے ڈیزائن کے طرز پر بنایا گیا ہے۔

اس ماڈل میں پسٹنز کی جگہ لیزر کا استعمال کیا گیا ہے۔

سائنسدانوں نے یہ تحقیق یونیورسٹی آف سٹٹگارڈ کے میکس پلینک انسٹیٹیوٹ فار انٹلیجنٹ سسٹمز میں کی اور نیچر فزکس نامی جریدے میں شائع ہوئی ہے۔

سائنسدانوں کا کہنا تھا کہ وہ اس بات پر حیران ہیں کہ یہ انجن کس قدر مؤثر طریقے سے حرارت کو قابلِ استعمال طاقت میں تبدیل کرتا ہے۔ لیکن ان کا یہ بھی کہنا تھا کہ اس انجن کا چلنا ہموار نہیں ہے اور اس وقت اس انجن کا کوئی کارآمد استعمال نہیں ہے۔

روایتی سٹرلینگ انجن میں ایک گیس کا سلنڈر استعمال ہوتا ہے جس کے ایک حصے کو گرم اور دوسرے حصے کو ٹھنڈا کیا جاتا ہے۔گیس کے گرم ہو کر پھیلنے اور ٹھنڈی ہو کر سکڑنے کی مدد سے سلنڈر سے منسلک دو پسٹنز کو چلایا جاتا ہے۔

پروفیسر کلیمنز نے بی بی سی کو بتایا ’ہم یہ سمجھنا چاہتے تھے کہ یہ بنیادی طور پر کیسے کام کرتا ہے اور کیا یہ خوردبینی حد تک چھوٹے آلات میں کام کرتا بھی ہے یا نہیں ۔آج کل ہر کوئی الیکڑانک اور مکینیکل آلات کو چھوٹے سے چھوٹا کر رہا ہے تو ہم نے سوچا کیوں نہ اس اصول کی خوردبینی سطح پر تحقیقات کی جائیں۔‘
