Hot Dry Rock - Coming of Age?

September 8, 2010

Analysis of:Hot Rocks and High Hopes | www.economist.com

The concept of utilizing the natural heat of the Earth to generate useful energy has been around for a very long time. Until now, the geothermal energy industry has relied exclusively on rare and hard-to-find underground steam or hot water - i.e. "hydrothermal" resources.Hot Dry Rock energy, is a game-changer because it is ubiquitous. Enabling technologies are now evolving to unleash the vast potential of this ultra-low environmental impact energy source. Is now the time for Hot Dry Rock?

Hot Dry Rock Geothermal Energy - Too Clean, Too green, Too Abundant to Ignore!

July 8, 2009

Analysis of:Deep in Bedrock, Clean Energy and Quake Fears | www.nytimes.com

The recent New York Times article highlights the massive potential of Hot Dry Rock Geothermal energy (or Engineered Geothermal Systems -EGS), and raises public awareness of this unique and virtually untapped source of energy. Unfortunately, the article also may trigger undue fear and anxiety by focusing on one particularly flawed example and failing to explore the broader range of technical options for accessing this abundant and renewable energy resource. The public deserves a fair and balanced discussion of the technology and all of its implications.

Plug-in hybrids - a misguided quest

March 28, 2007

Analysis of:In Quest for Cleaner Energy, Texas City Touts Plug-In Car | online.wsj.com

As a near term solution to global climate change concerns or dependence on fossil fuels, the plug-in hybrid ranks dead last among the many alternative engine technologie that are being developed by Automakers.

The rush to promote plug-ins as a feel-good "green" technology is a well intentioned, but horribly misguided because the use of Plug-in electric hybrids will add to rather than reduce greenhouse gas.  

   

Handicapping the winners in a crowded field of innovation

March 26, 2007

Analysis of:Which Green Car Is Best? | www.businessweek.com

With a surprising number of innovative powertrain technologies on display at this years' auto shows, there are some winners and some losers worth mentioning. Clean diesel is clearly the dark horse and the one to watch while hybrids are likely to fade from popularity due to their high cost, high complexity, and lower (more accurate) EPA fuel efficiency ratings beginning in 2008. The loser could well be Fuel Cell commercialization which may be further delayed as a result of these simpler and more readily available alternatives. 

Can Detroit's Automakers be saved from themselves?

March 23, 2007

Analysis of:U.S. auto chiefs cool to tougher Cafe standards | www.marketwatch.com

Detroit's automakers have long been masters at avoiding the imposition of mandated technology. In Detroit, the greater public interest has always taken a backseat to the local politics of union jobs and automaker profitability. By contrast, automotive leaders in Japan have typically taken a longer view - as Fujio Cho, Chairman of Toyota once stated "Without environmental initiatives, the automotive industry has no future." 

Meanwhile, the U.S automakers continue to resist at their peril - risking relentless erosion of market share and ultimate marginalization. The perception that mandated fuel efficiency standards impose undue burdens on an already stressed industry is, at the core, a false premise. It may take congressional action to save what used to be "The Big Three" from themselves.
