Battery advance could boost renewable energy take-up

By Paul Rincon, Science editor, BBC News website

US researchers have made an important step forward in the quest to store electricity from intermittent energy sources such as wind and solar.

A Harvard University team came up with a way to drive down the cost of flow battery technology, which is capable of storing energy on large scales – within an electrical power grid, for example. Grid-scale storage for renewables could be a game-changer – making wind and solar more economical and reliable.

The missing link to renewable energy

What’s the key to using alternative energy, like solar and wind? Storage — so we can have power on tap even when the sun’s not out and the wind’s not blowing. In this accessible, inspiring talk, Donald Sadoway takes to the blackboard to show us the future of large-scale batteries that store renewable energy. As he says: “We need to think about the problem differently. We need to think big.

The uniqueness of Sindh

– By Ayaz Amir

Just when the sector commanders had been put on the back-foot, and the MQM was vociferating in a manner not seen since 1995 (Gen Babar’s operation), who should come to their rescue but President Zardari’s personal emissary, Montecello University’s most celebrated doctoral figure, Dr Babar Awan.

He has brilliantly appeased the MQM by restoring Gen Musharraf’s  loaded [undemocratic, black, repressive & discriminatory] local government system – first just to Karachi and Hyderabad and then, when … Sindh rose up with one cry against this hasty move, to the whole of Sindh. The MQM can hardly believe its luck – perhaps it hadn’t counted on so swift a Zardari capitulation – but anger in … Sindh is on the rise.

Dr Zulfiqar Mirza’s outbursts had angered the MQM but secured the PPP’s vote bank in rural Sindh. Dr Awan’s gymnastics have pleased the MQM but poured fuel over the burning embers of Sindhi anger. From one extreme the PPP has swung to the other.

The choice of Dr Awan as PPP plenipotentiary was bizarre. How was he qualified to negotiate on behalf of Sindhi interests? The PPP is now on the back-foot. All the certificates of cleverness earned by Zardari for his supposed political sharpness have gone with the wind.

Dr Awan has proved adept at stalling and frustrating the Supreme Court. From the PPP’s point of view, he should have confined himself to that doctrine of necessity instead of floundering in the waters of Sindh.

In an ideal world, the PML-N should have been quick to exploit this opening. Alas, if wishes could be horses. It showed itself eager, a bit too eager, to embrace the MQM when the latter fell out with Zardari. But this proved embarrassing when the MQM’s falling-out proved to be less than definitive. Small wonder, it has yet to get its thoughts in order on the anger on the rise in backwater Sindh.

All of us could do with some clarity on a crucial issue: while the logic of smaller provinces applies to Punjab, because it is too huge and unwieldy, it does not, and cannot, apply to Sindh. Babar Awan and the PPP came perilously close to the idea of Sindh division when they proposed one dispensation for Karachi and Hyderabad – the restoration of Musharraf’s  [undemocratic, black, repressive & discriminatory] local body system – and another for the rural, revival of the commissionerate system. Sindh rural instantly saw red and the PPP had to back down immediately, in the space of a mere 24 hours. But the alarm had been sounded and Sindhi concerns have yet to be addressed or placated.

Carving a southern or Seraiki province out of Punjab will not endanger Punjab identity. Indeed, it will facilitate the task of governance and give a sense of belonging to the people of southern Punjab who feel left out of the orbit of Punjab affairs. But anything even remotely connected to the notion of Sindh division is almost an invitation to dangerous conflict in this most sensitive of provinces.

We should not forget the history of 1947 migration. If we leave Bengal out of the equation, there were two great waves of migration in northern India at the time of Partition: one from East Punjab to West Punjab, and vice versa; the other from Delhi, Lucknow and Bhopal in the north, and Hyderabad Deccan in the south, to Karachi. These migrations were dissimilar in character.

While Punjab suffered the most in terms of looting, plunder, killings and mass rape, when the dust settled and passions had time to cool, the process of assimilation was relatively quick because East and West Punjabis, minor differences of course apart, came from the same cultural stock. With minor variations of dialect, they spoke the same language and shared the same history.

This was not so with the southern migration to Karachi and Hyderabad. Karachi was a cosmopolitan city even then – a mini-Bombay, so to speak – but it was the capital of Sindh, the culture and language of whose native inhabitants was radically different from that of the people who were coming to it from India.

Karachi soon became the centre not of Sindhi culture but of the culture of displaced Dehi, of Delhi as it had been before the tumult of Partition. Delhi today is a Punjabi city. Its old composite, Muslim-dominated culture, the culture from which arose the poetry of Mir and Ghalib, is a thing of the past, lost to the upheavals of time and history. No conqueror, not Taimur and not Nadir Shah, could destroy Delhi, or transform its character, as decisively as Partition did. Those who seek the old Delhi, authors like William Dalrymple, have to come to Karachi to catch a whiff of the past.

Pakistan would be the poorer without this infusion of Delhi, Lucknow and Hyderabad Deccan culture. True, there was a downside to it as well, …. brought with their culture also their own prejudices. Insecurity and fear were part of their migrational baggage and these were infused into the thinking of the new state. But in cultural terms the arid wastes of Pakistan were enriched by that influx of talent and learning.

Punjabis being Punjabis, no new centre of culture arose in Punjab. But in Karachi we saw the birth of a transplanted culture, its soul carrying the imprint of loss and nostalgia, the usual hallmarks of any migration.

The downside comes from this very circumstance. Sixty four years after Partition we continue to live in the past, beset by old insecurities even though the times have changed and the old certitudes which gave birth to those insecurities no longer survive.

Sindhis are entitled to be a bit upset by all these changes. After all, they too are the inheritors of a great civilisation. Moenjodaro is the oldest pre-historic site discovered anywhere in India. There are other mighty life-giving rivers in the sub-continent: the sacred Ganges, the winding Brahmaputra. But only the Indus, sacred river of Sindh, gives its name to India. Hindus migrating to India from Sindh in 1947 take great pride in their Sindh ancestry.

Sindhi anger, nay Sindhi anguish, is centred on a primal concern. Why must the transposing of cultures be at their expense? And there is a fear lurking in their hearts, the fear of the Red Indian and the aborigine, of becoming strangers in their own homeland. This is a concern which must not be scoffed at. The rest of us, and this includes the successors to the civilisation of Delhi, should avoid words or gestures that smack even remotely of designs against the unity and integrity of Sindh.

From the immortal land of the five rivers, now only three left with us, thanks to the vagaries of history, more provinces can be carved out and no harm will come to it [Punjab]. But let no Punjabi leader or politician say that if Punjab is to be divided the same logic should apply to other provinces. This is wrong thinking. The same logic does not apply to Sindh, it does not apply to Balochistan. It is relevant only to Punjab and Punjab will be doing itself and the nation a service if it takes the lead in this respect, illuminating the path that others can follow.

A word may also be in order about another fixation of the Punjabi mind: Kalabagh dam. If Kalabagh dam is right then there is nothing wrong with the dams India is building on the rivers Chenab and Jhelum. If we are objecting to run-of-the-mill dams in Kashmir, dams whose water is not stored but is allowed to run, how can we support a storage dam on the Indus at Kalabagh? The logic just does not hold.

History cannot be undone. We have to live by its consequences. But Sindh of all regions of Pakistan requires a balance and moderation in the conduct of its affairs. Any hint of an unnatural hegemony of one part over the other is an invitation to anger and despair.

Kayani & Pasha with Haroon Rashid & Imran Khan can draw whatever they want in drawing room but …?

Enter the Midwife: Haroon Rasheed

by By Col. (r) Ikramullah Khan

Anyone who has tuned into a talk show or read an opinion piece in the last few weeks knows that the ghosts of the old IJI are dyeing their hair, whistling into the mirror and preparing to come out of retirement. The parade of news stories involving ISI plans to cobble together an alliance of different political parties to rout both PMLN and PPP in the coming elections is unending. The usual suspects that have frequently been mentioned are PTI, MQM, JI, PMLQ, PML-F and JUI-F.

Great political leaders of the Pakistani people such as Altaf Hussain and Imran Khan have decided to bury the hatchet (along with the Scotland Yard investigations) and have vowed to work together from now on. Weather vanes like Maulana Fazlur Rehman and Peer Pagara have been active, and pointing towards the direction of the wind.

Pakistanis are used to the quick leaps, somersaults and pole vaults which are a characteristic feature of the lucky Irani circus which is our politics. But even hardcore supporters were left babbling by the strange noises that come screeching out whenever Imran Khan has tried to speak recently. There had been rumors of Imran Khan meeting with the American ambassador, General Pasha and General Kiyani for weeks. PTI has been denying these rumors suspiciously noisily with understandably counterproductive results.

As new details are coming to light, few will believe the depths being plumbed by some in our media and politics. Asia Times Online writes:

“In the second week of March, Khan held a long meeting with the US ambassador in Islamabad, Cameron Munter. A few days later a major shift in his politics surprised many. Khan produced a statement supportive of MQM policies despite formerly filing a money laundering case against MQM leader Altaf Hussain in a British court.

A prominent Urdu media commentator of right-wing leanings, who is close to both Khan and army chief Kiani, arranged a series of meetings between the two which eventually led to a consensus around Khan becoming the next leader of the country.”

According to the information in the article, the conspiracy has Imran Khan in the starring role and involves:

  • ISI is working towards mid-term elections before the scheduled date of February 2013
  • A new political alliance of MQM, PTI, JI and JUI etc. is being planned resulting in a simple majority under prime minister Imran Khan.
  • Haroon Rasheed arranged a series of meetings between Imran Khan and Gen Kiyani
  • If plans for a political alliance fail, Imran Khan will become the interim prime minister.

This brings us to the role of Haroon Rasheed, the one-man propaganda machine of the army and a suitable alternative to ISPR in case of downsizing. Balancing his gushing and embarrassing adulation of the military boot, Haroon Rasheed has made promoting Imran Khan a personal cottage industry, often in the same breath.

Just to illustrate the point, here is a recent display of pro-army douchebaggery (Jang, April 16th, 2011). Haroon Rasheed takes the politicians to task for everything wrong under the sun and salutes the army for smacking the Kerry Lugar Bill away, shooting down drones, interrupting the NATO supply lines, kicking out CIA agents and completely distancing the army from politics.
Well. Not exactly, but you have to read it to believe it.: ….

Pakistan Today Is Better Than It Was 20 Years Ago

by Farid Ahmad
Sitting in the middle of load-shedding, watching the political theater roll-on ad infinitum, and reading the news of another security incident somewhere, it is easy to be depressed about Pakistan these days.

Depression, however, is parasitic.

It jumps from person to person and grows in strength unless treated. It makes you weak and vulnerable  and sometimes it is necessary to break the circle. Yes, Pakistan is going through very tough times, but there is no reason to throw all hope to the wind and to start denying the things that are going right  and a lot has gone right in the past twenty or so years.

First, the necessary disclaimer: The intention here is not to sweep Pakistan’s problems under the rug or to try and rationalize away the immense suffering of the victims of recent violence and economic turmoil. There is no doubt that things have taken a very serious turn in recent months and millions of people are paying a heavy price every day.

With that disclaimer in place, here’s a collection of things that I have seen change for the better in my life in Pakistan – from high-school in the eighties to today.

It is necessarily a very personal list, though others might be able to relate to some of it. Traveling apart, I’ve spent my life living in Islamabad and Lahore and my memories are naturally specific to these places. So again, I’m fully conscious of the fact that not everyone can relate to or agree with my attempt at optimism.

But even if I come across as being overly optimistic, it is only to counter those who are becoming unnecessarily pessimistic.

Maybe you have your own stories, your own inspirations, your own rays of hope that keep you going… these are mine. And I share them with the hope that they will help someone else break out of the circle of pessimism.

Roads: 1989: Driving from Lahore to Islamabad was an ordeal on the mostly single-lane, badly maintained GT road.
2010: Driving from Lahore to Islamabad is a pleasure on the motorway. And it is not just this one road, a lot of roads have been added to the network or improved. I know people in my office in Islamabad who routinely drive to Karachi with their families. We need many more roads – but we have certainly not been sitting idle.

Communications: 1989: Calling from Islamabad to Lahore meant going to the market to a PCO, telling the guy to book a 3-minute call and waiting around till it got connected. Even if you had an STD line at home, your fingers were likely to get sore from dialing before you got connected. And once the call was connected you watched the clock like a hawk as it was so expensive.
2010: Instant, cheap calls worldwide for everyone from cellular phones.

Internet: 1995: I was first introduced to the wonders of Email in 1995. It was an offline ‘store and forward’ system (remember those @sdnpk email addresses?) . If you sent a mail in the morning, it reached in the evening when your Email provider called USA on a direct line to forward it.
2010: Broadband, DSL, WiMax, Dialup, Cable – instant connectivity for everyone. More generally, I’ve gone thru a series of denials about the adoption of new technologies in Pakistan. I went through thinking that cellular phones would never gain widespread adoption – I was wrong; that internet would remain a niche – I was wrong; that broadband would never take off here – I was wrong; that Blackberry would never be adopted – I was wrong. Here I speak from some experience as I work for a cellular company and I’ve seen all these numbers grow exponentially. The fact is that Pakistan and Pakistanis love technology and are eager to adopt and adapt the latest technologies as soon as they become available. With its huge population, this creates a large market for every new technology in Pakistan and businesses rush in to fill it. This bodes well for the future. ….
