“I’m Chris Lewicki, and I’m an asteroid miner!” These were the opening words spoken by the President and Chief Engineer of Planetary Resources Inc., as the asteroid mining company emerged from three years of silent running to outline its plans to mine Near-Earth Asteroids (NEAs) within the decade.  Read More

Snap of Google Earth U.S. geothermal resource map based on SMU research

As a green energy source, geothermal heat is tough to beat, but until recently, it was believed to be economically feasible only in areas with shallow tectonic (volcanic) activity. Now, with a generous grant from Google.org, the search engine giant's philanthropic arm, two scientists from Southern Methodist University (SMU) have pooled together the results from more than 35,000 data sites to paint a very different, almost rosy, energy picture for the United States and, indeed, the world.  Read More

A year ago, the twin impacts of NASA’s LCROSS (Lunar Crater Observation and Sensing Satellite) spacecraft and a companion rocket stage into the lunar surface revealed the presence of water on the moon. Now new data uncovered by LCROSS and the Lunar Reconnaissance Orbiter (LRO) has revealed that the lunar soil within shadowy craters is rich in useful materials, and that the moon is chemically active and has a water cycle.  Read More

Can the Earth sustain 9 billion people? We'll find out in the next 50 years.

We're living in lucky times. Living standards - in the Western world, at least - are the highest in history. It's an era of relative peace and plenty that would amaze our ancestors. But it's not going to continue forever; we're already stretching many of our natural resources to their limits, and the world's population will jump from 6.5 billion to around 9 billion over the next 50 years. Get ready for a painful correction - here are four interconnected resources that are headed for a catastrophic squeeze within our lifetime.  Read More

A Metal-Organic Heat Carrier (MOHC) molecule that may help improve thermodynamic efficienc...

Geothermal power is cost effective, reliable, and environmentally friendly, but it has previously been limited to geographic areas near tectonic plate boundaries. New technologies, such as that employed in the Raser low-temperature binary geothermal plant, promise to expand the opportunities for geothermal plants. Now scientists at the Department of Energy's Pacific Northwest National Laboratory (PNNL) have devised a method for capturing significantly more heat from low-temperature geothermal resources to further boost the possibility of virtually pollution-free electricity.  Read More
