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.

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.

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.
