  • A Crystal Clear Solution

    Iron oxide residues in groundwater are becoming an increasing problem, estimated to affect about 40% of the world’s water bores, and anecdotal evidence indicates that this number is steadily increasing. Whether caused by naturally occurring bacteria or straight chemical means, these residues will eventually affect nearly everyone who sources water from groundwater aquifers. This case study ...

  • Determining the circulation depth of thermal springs in the southern Rocky Mountain Trench, south-eastern British Columbia, Canada using geothermometry and borehole temperature logs

    Geochemical data for thermal spring waters along the southern Rocky Mountain Trench in British Columbia, Canada were examined. The range of equilibration temperatures for the thermal springs is between 24 and 59°C, assuming that there is minimal mixing with colder shallow waters that might lead to a lowering of the calculated equilibration temperature. The chalcedony geothermometer is found to be ...

  • Asia-Pacific Analysis: Go green not nuclear

    Crispin Maslog says the region should follow the Philippines' lead and focus on renewable, not nuclear power. A year after the Fukushima nuclear disaster, questions remain over the role of nuclear power in the developing world, including ...

  • Reaching underground resources

    Accessing critical resources such as geothermal energy and natural gas requires drilling — an expensive, energy-intensive, messy process with today's technology. An MIT team has been looking into a more elegant approach. Instead of grinding rock to bits, they would use a continuous beam of energy to vaporize it and then blow out the tiny particles that form with a high-pressure stream of ...

  • G7 Climate Vision requires Gargantuan Economic Shift

    When leaders of the Group of Seven wealthy countries pledge to "decarbonize" the global economy, they're talking about a shift so dramatic that one analyst described it as a new Apollo mission. Like putting a man on the moon, it would require overcoming major hurdles related to technology and money and the political will - so far in short supply - to make it happen. Despite gains by renewable ...

  • Heat Pumps – FAQs

    1. What is a Heat Pump? To put it simply; ground source heat pumps and geothermal heat pumps produce high grade heat from low grade heat which is found in the earth and our atmosphere.2. How does a Heat Pump Work?Heat pumps work in exactly the same way as air conditioners or refrigerators, but in reverse! Heat pumps capture latent energy which is stored in sources such as air, water and earth. ...

  • Insurance for Crossing the Valley of Death

    To achieve a modest reduction in atmospheric carbon dioxide emissions, global investment in renewable energy assets would need to increase from current levels of about $100 billion per year to $500 billion per year. Some of this increase can be accomplished by investment in existing, commercially proven technologies; but to meet the challenge of rapidly scaling renewable energy, we also need to ...

  • Renewable, local power options expand

    It makes no economic sense to run more than one set of wires from electric power generators to homes and businesses. That’s why consumers haven’t had a choice about the source of their electric power – whether it be an investor-owned utility (IOU), municipal utility or electric cooperative. Enabling consumers to choose between competing energy providers is a paradigm shift, and ...

  • Oceans of Energy

    Technologies that harness the energy of moving water or temperature differentials in the oceans promise to deliver abundant carbon-free electricity. Long before humans got hooked on fossil fuels, we learned how to harness the power of water to do work. Rivers ran mills that ground flour, sawed logs or spun looms that transformed fibers into textiles. Later generations realized that moving water ...
