Comments Off on Affordable home geothermal energy systems come to upstate New York

When you think of home renewable power systems, geothermal energy probably isn’t the first source that springs to mind. But new company Dandelion , which starts after time at Google’s moonshot factory X , aims to power houses with the clean , free source “right under our feet.” They’re offering their systems beginning in northeastern America. The Dandelion team launched their company independent of Alphabet this month, offering geothermal heating and cooling for homes. They come in and replace cooling, heating, and hot water equipment with their geothermal systems, including underground pipes and a heat pump, which gather energy from the earth. The company describes geothermal cooling and heating as the most efficient method of such climate control for the home.

They say many homes haven’t yet adopted geothermal systems due to the hefty cost associated with setup. In contrast, Dandelion’s system costs $20,000. On their website they say they’ve partnered with a leading financing company to install the systems with zero costs upfront followed by low monthly payments. The company also designed a better drill to install the systems. In the past, geothermal systems were installed with a wide drill that was intended for water wells more than 1,000 feet into the ground. The Dandelion team designed a slender drill that can create one or two deep holes a few inches wide – with less waste. Their new drill lets them put in ground loops in under one day. Overall, putting in their geothermal systems takes two to three days. Dandelion’s heat pumps will last around 25 years, while the closed-loop piping can last for a minimum of 50. The system comes with a smart thermostat enabling homeowners to regulate the temperature inside. The team is starting with 11 counties in New York – they say regions with cold winters and hot summers are ideal for home geothermal systems. + Dandelion Via Kathy Hannun on Medium Images via Dandelion Facebook and Dandelion

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
