The First Magma-Enhanced Geothermal System|
January 28, 2014 | University of California, Riverside
“Despite some difficulties, the project was able to drill down into the molten magma and control it; it was possible to set steel casing in the bottom of the hole; allowing the hole to blow superheated, high-pressure steam for months at temperatures exceeding 450 C, created a world record for geothermal heat.” Quoted from the University of California, Riverside press release.
US Energy Mapping System|
January 5, 2014 | Energy Information Administration
The Energy Information Administration has an interactive map of energy locations in the United States. You can use it to plot data layers showing the location of wind (see map sample below), coal mines, biomass plants, geothermal, hydroelectric, and many other types of energy projects.
Courthouse to Stream in an Open Loop Geothermal System|
November 21, 2013 | The Martinsburg Journal News
The court house at Berkeley Springs, Morgan County, West Virginia has an unusual geothermal system. It removes water from a local stream, pumps that water through a heat-exchange system and returns the water to the stream. Open-loop systems connected to a stream are rare.
Fracking for Geothermal|
October 25, 2013 | MIT TechnologyReview.com
“The use of hydraulic fracturing has unlocked vast new reserves of natural gas. Now Alta Rock, a startup based in Seattle, is developing technology that might do the same for geothermal resources, turning a marginal power source into a major source of carbon-free electricity and heat.” Quoted from the MIT TechnologyReview.com article.
Icelandic Expertise for Ethiopian Geothermal|
September 30, 2013 | Bloomberg.com
Iceland is a country with demonstrated expertise in developing geothermal energy of all types. Now an Icelandic company has agreed to a geothermal project that might bring up to 1,000 megawatts of capacity to Ethiopia.
Ikea Store to Have 180 Geothermal Wells|
September 19, 2013 | KansasCIty.com
A new 359,000 square-foot Ikea store near Kansas City is being built with a geothermal heating/cooling system. They are drilling 180 wells to a depth of 600 feet to create a closed-loop ground-source heat pump system.
Micronutrient Plumes from Hydrothermal Vents|
September 16, 2013 | Woods Hole Oceanographic Institution
“Scientists have discovered a vast plume of iron and other micronutrients more than 1,000 km long billowing from hydrothermal vents in the South Atlantic Ocean. The finding [...] calls past estimates of iron abundances into question, and may challenge researchers’ assumptions about iron sources in the world’s seas.” Quoted from the Woods Hole Oceanographic Institution press release.
Ground-Source Geothermal Heating and Cooling|
September 15, 2013 | Arizona Geology Magazine
The recent issue of Arizona Geology Magazine has an introductory article titled: Ground-Source Geothermal Heating and Cooling: Sustainable and Affordable Energy for Arizona and the U.S.. The article features Lookout Mountain Elementary School where a new ground-source geothermal system that exchanges heat with the cooler earth hundreds of feet below the ground surface.
Exploring for Geothermal with Self-Flying Planes|
September 9, 2013 | USGS
USGS has an article that explains how they have been using self-flying planes to evaluate the geothermal potential of the Basin and Range area.
Switching Hawaii from Oil to Natural Gas?|
September 4, 2013 | National Public Radio
Hawaii has been addicted to expensive oil for decades when many people thought that they would be running all of the islands off of hot rocks, sunlight, ocean breezes or wave power. Now they are looking to bring natural gas to the islands. One problem is that natural gas from USA wells can not delivered to Hawaii because an old law requires the transporting vessel to be built, registered, manned, owned and licensed by people in the USA – and not one vessel like that exists.
September 4, 2013 | Imperial Valley Press
The production and reinjection of water at geothermal energy plants in California may have caused differential subsidence of agricultural fields that has disrupted their irrigation and produced low spots where crop loss occurs.

Plumbing Under the Greenland Ice Sheet|
August 27, 2013 | National Science Foundation
“Scientists’ understanding of how Greenland Ice Sheet melt water travels in passages along the bedrock below fails to account for some key processes. This, in turn may be affecting their assessment of how ice sheets respond to climate change.” Quoted from the National Science Foundation press release.
