India's diesel-powered train network has a new kid on the block. The gas-guzzling Indian Railway system has just debuted its first solar-powered train, called the Diesel Electric Multiple Unit (DEMU). It will operate in the city of New Delhi.

Placement of the solar panels on the train car was challenging. Sandeep Gupta, Vice Chairman and Managing Director of Jakson Engineers Limited (the company that produced and installed the solar panels) told Business Standard, "It is not an easy task to fit solar panels on the roof of train coaches that run at a speed of 80 km per hour." The panels feed into an onboard battery that can store surplus power.

The train will still be pulled by a diesel locomotive; the solar panels will only power passenger comfort systems, such as lights, information displays and fans. Even so, Indian Railways estimates that just one train with six solar-panel equipped cars will save 21,000 liters (5,547 gallons) of diesel fuel per year, at a cost savings around Rs12 lakh (almost $20,000).

[Editors note: per the articles, the train is diesel powered, not solar powered, only the electrics in the cars are solar powered. However, they still hope to save $6B in fuel costs in the coming years]

    the visions I had early on were quite beautiful.

    When the visions didn't turn up in the prints, I bought some books on professional photography and learned to develop and print my own film in the Caltech student darkroom.

    That was 33 years ago, yet the visions still haven't turned up in the prints.

    Heh, Your post about photographing visions reminded me of something.

    I had a (painless) ocular migraine a few weeks ago. Scared the crap out of me at the time as I had no idea what it was. My eye doc diagnosed it, and afterward while trying to explain it to others I looked it up online; where people have created images and videos to try to describe it. But it doesn't quite... there is a visceral quality that can't be captured... in the pictures and the videos you can look at the effect, but when living it... you can't; it sits in your peripheral vision, in sight but perpetually just out of focus, and it slides away if you look at it.
