Hot dry rock technology was invented to draw energy from deep underground areas where geothermal heat is abundant, but no water exists to carry the heat to the surface.
Australian company Geodynamics Ltd. has completed drilling on the first commercial attempt to create a commercial geothermal power plant using hot dry rock technology. Total depth of the production well is 13,850 feet.
A new method that facilitates the initial rock exploration in tunnel construction has received a technology award for its innovation. The sonar-based system permits exploration without explosives and while drilling is taking place.
Ground Water and Geothermal Associations Join Forces The National Ground Water Association and the Geothermal Heat Pump Consortium Inc. have signed a memorandum of understanding to foster cooperation in addressing shared interests involving ground water and geothermal heating and cooling.
ITT Provides Safe Drinking Water in Quake-Affected Areas of China
ITT Corp. has donated eight of the company's portable water purification units and replacement parts to areas of southwest China affected by the devastating earthquakes. The portable treatment equipment will provide clean water for 200,000 people living in shelters.
Ice Cores Map SuddenClimate Changes Drilling nearly 2 miles into the Greenland ice cap provides clues to more than 100,000 years of climate change in the Northern Hemisphere.
Illegal Wells Damaging Water Supply Illegal water well drilling is depleting the ground water resources in Ha Noi, Vietnam. According to a recent report, there are approximately 20,000 illegal wells in the city. Drilled to an average depth between 65 and 82 feet, the wells have become conduits for contamination to the water supply. Many of these wells for domestic use have been drilled near toilets and pigsties. Some restaurants and breweries are producing bottled water and beer using the untreated water, and other businesses, like laundry facilities and car washes, are using them to cut costs. Those caught drilling illegally face fines, however, the wells can be difficult to find because they're hidden within homes and
businesses.

Accidental injuries cost Americans more than $650 billion annually, and 16 workers die every day on the job in the workplace. June 2008 is National Safety Month. With a theme this year of "Make a Difference," the public awareness event is intended to be a call to action for employers and organizations to help reverse a national increase in accidental injuries and deaths.
