Geothermal Power Sources

Geothermal Energy CycleMainly because Calpine is committed to offering shoppers with clean, fuel-efficient, trusted electricity, the organization focuses on two key technologies: combined-cycle natural gas-fired and geothermal power generation.

Low-temperature and co-produced geothermal sources are typically located at temperatures of 300°F (150°C) or much less. Some low-temperature resources can be harnessed to generate electricity working with binary cycle technologies. Co-created hot water is a byproduct of oil and gas wells in the United States. This hot water is getting examined for its prospective to produce electricity, assisting to lower greenhouse gas emissions and extend the life of oil and gas fields. Get additional data about low-temperature and co-developed resources from the U.S. Department of Energy’s GTP Internet site.

Balneotherapy is the remedy of illness by spa watersusually bathing and drinking. Some renowned spas in the United States that offer balneotherapy incorporate Hot Springs, Arkansas, and Warm Springs, Georgia. The most popular balneotheraputic spa in the world, Iceland’s Blue Lagoon, is not a organic hot spring. It is a manmade feature exactly where water from a regional geothermal power plant is pumped over a lava bed rich in silica and sulfur. These elements react with the warm water to develop a bright blue lake with alleged healing properties.

A binary cycle power plant works with geothermal liquids at a reduced temperature than dry stream and flash stream plants. The temperature of the water is significantly less than 350 degrees Fahrenheit. Water is pumped from a geothermal effectively via a heat exchanger and cooled water is returned to the underground reservoir. A second fluid with a low boiling point is then pumped at a high pressure through the heat exchanger and then vaporizes directing the turbine. It is then condensed by a cold air radiator or cool water and cycles back through the heat exchanger.

Currently I teach Environmental Sustainability and Justice to students from around the globe at Mercy College in New York and I go all around the world teaching communities how to make their own meals waste to fuel and fertilizer and fresh food renewable energy systems with National Geographic. We are teaching that we can turn all that waste not just into clean fuel but that we can use it to grow food in the desert, that we don’t want soil at all. At my college and in Cairo we use it to make food from hydroponics and aeroponics in rooftop gardens.
