Are watermills in Kashmir a solution to Pakistan's energy crisis?

Arshad Rashid thinks he has an answer to his country's energy shortages.

For a few hours a day, a few days a month, the villager in Katahi, about 50 kilometres outside of Muzaffarabad, the capital of Pakistan-administrated Kashmir, grinds maize and wheat with a watermill.

But he sees untapped potential in his century-old mud-and-stone mill, which sits idle most of the time. He wants to use it to generate free, clean electricity.
