Spring has crept up to the foothills of the Himalayas and, in Islamabad, Pakistan's purpose-built capital, the air is full of the scent of roses and the yelling of birds.
Yet, even in this most stately of South Asian cities, it is impossible to escape the realities of an unstable nation that has yet to figure out how to meet some of the basic needs of its 200 million or so citizens.
Islamabad long ago adjusted to attacks by Islamist militants by setting up roadblocks and turning its government buildings, five-star hotels, villas and diplomatic enclaves into modern-day fortresses, wrapped in razor wire and blast barriers and monitored by a multitude of security cameras and armed guards.
But the more recent blot on the life of the city is much more mundane: It comprises long lines of angry and frustrated motorists, parked along the edge of Islamabad's tree-lined avenues, waiting for hours to refuel their vehicles.
For "long" read huge. Some of these lines stretch well over a mile. Drivers say it sometimes takes four hours to reach the gas station.
A Cheaper, Cleaner Alternative
The problem is caused by a major shortage of CNG, or compressed natural gas. Pakistan has millions of cars equipped to run on CNG, more say officials than anywhere else in the world.
These vehicles include the small and battered yellow Suzuki taxi driven by Abdul Majid. Majid's taxi is about midway in a line for a distant gas station; he says he's already been waiting for an hour and a half.
He is so bored and fed up with spending half his life in a queue that he's talking about giving up the taxi trade altogether and finding something else. He might be forced to. He says his meager daily take-home pay of about $10 has dropped by half. Like many cars here, his taxi actually can also run on gasoline but that's three times more expensive and would eliminate his tiny profit margin. Thus, the huge lines.
With a family of six to feed, Majid says he's struggling: "For [the past] three days, I have no bread at home."
Pakistan's government started encouraging people to use CNG about 10 years ago. It wanted to cut the country's hefty bill for imported oil and use Pakistan's domestic gas reserves instead. CNG has the added benefit of being cleaner and cheaper than regular gasoline. At first, the plan was a huge success.
Then, the problems began.
A Solar Solution For The People
As industry and the public competed for energy amid massive and unrelenting power outages, demand for natural gas soared. A court ruled CNG retailers were making excessive profits and ordered a cap on prices, causing hundreds of CNG suppliers to close down. Separatist insurgents in Pakistan's Baluchistan province where a lot of the gas comes from regularly bombed the pipelines. CNG began to look like a bad idea.
When adversity strikes in Pakistan as it does, regularly someone usually fights back.
Enter Aslam Azad.
Five years back, Azad began what became a kind of personal mission to find an answer to Pakistan's CNG crisis.
He spent some $500,000 of his own money on creating a car powered by the sun. The prototype looks like a golf cart with solar panels on the roof, hood and sides.
But looks aren't important right now, says Azad; the snazzy design will come later.
Azad is managing director of a company that specializes in heating and cooling systems and has won some lucrative contracts over the years. But he says building the solar car is not about profit: "This is because my people needs me," he explained, as he drove this correspondent slowly through Islamabad in his solar-powered buggy.
"I'm pretty sure this is what we are looking for," he continued. "This will solve the problems of people, and the lines, and the financial crisis."
The car is powered by solar and kinetic energy (the engine becomes a generator when it's coasting). At present, it can run for about 50 miles a day before recharging, but Azad is planning to replace the current battery-run system with technology that will increase its range by up to five times.
Many other pioneers around the world are also working on solar-powered vehicles, often hybrids, but Azad says his car has the advantage of being unusually inexpensive just a couple of thousand dollars.
He's confident Pakistan's government will grant him a manufacturing license in the coming months, and that Pakistan's angry and frustrated motorists will leap at the chance to get out of line, and buy his car: "I am pretty sure this will succeed. I have no doubt. I just have no doubt."
Cabbie Ahktar Farooq says he can't afford a solar car; all the same, he eagerly hopes for its introduction, in the hope that other people can.
After spending four hours in one of those giant lines, Farooq has given up hope. The gas station's about to close; he is heading home. It's always like this, he says. "Sometimes we get it [the CNG] and sometimes we don't get it and we just go home, with empty hands."
