Comments Off on Indian Railways launches first train with solar-powered coaches

Train travel in India just got a little greener. Last week Indian Railways rolled out their first train outfitted with rooftop solar panels – in the Delhi area notorious for its pollution . The solar panels will completely power fans, lighting, and display systems in the coaches. The government expects the move will save them around 5,547 gallons of diesel every single year. The train, a 1600 HP DEMU, is just the first of several more trains with solar-powered coaches to come. Indian Railways will install solar panels on 24 other trains in the upcoming six months. In the past, a diesel-fueled generator provided electricity for a train’s lighting and fans, but the new solar system includes a smart MPPT inverter so these features can be cleanly powered even during the night. According to Indian Railways, the solar panels will slash carbon dioxide generation by nine metric tons per coach per year.

The system can generate around 20 kilowatt-hours of clean power per day. A 120 AH battery system will store excess power generated during peak hours. Minister of Railways Shri Suresh Prabhakar Prabhu said the railways are committed to conserving the environment and using more clean energy . The government’s press release on the trains pointed to other measures the railways have taken to become more environmentally friendly, such as the use of bio-toilets , biofuels, and wind energy. Jakson Engineers, under the guidance of the Indian Railways Organization for Alternative Fuels (IROAF), developed the new train solar system. Managing director Sundeep Gupta told Business Standard is was no easy feat to attach solar panels to trains that will move at speeds of 80 kilometers per hour, which is around 50 miles per hour. The train has a lifetime of around 25 years. Via Quartz India and Government of India Images via screenshot and Ministry of Railways on Twitter

Human construction projects could wipe out the world’s last wild tigers

Comments Off on Human construction projects could wipe out the world’s last wild tigers

A new report from WWF reveals that tiger habitats in Asia could be devastated by planned infrastructure that would fragment their range and increase confrontations between wild tigers and humans. There are fewer than 4,000 tigers left in the wild, and if these new roads and railways aren’t planned carefully, it could completely wipe out the slow, painful progress conservationists have made to preserve the species in recent years. The report comes during what could be a turning point for the animals – halfway through an effort on the part of 13 nations to double wild tiger population . In 2010, there were only an estimated 3,200 left on the planet. As of this April, there are thought to be 3,890 . If these Southeast Asian nations are going to reach the goal of 6,400 by 2022, the $8 trillion they’ve allocated to infrastructure projects in coming years needs to be sustainable and avoid critical areas where tigers live. Related: Tigers declared extinct in Cambodia Part of the problem is that it’s very hard to track tiger populations , so no one’s completely sure exactly where they live, or how to best avoid their territory. The WWF is advocating a few approaches for mitigating the potential harm to tigers: first, construction should be banned in areas that have been identified as critical tiger habitat; second, the countries involved should take a zero-tolerance approach to poaching ; and third, underpasses and green bridges should be built into any new infrastructure to allow wildlife to cross roads and train tracks safely. This approach would also have benefits for humans living in these areas: for instance, the initiative could help protect local water supplies. While conservation may be the primary question on the mind of the WWF’s researchers, government officials should keep in mind that human beings have to be able to live sustainably on this planet, too.
