On the heels of the violent storm system that felled enough overhead wires to disrupt electricity for 4.3 million utility customers on the U.S. East Coast,  new research suggests that the technology for transmitting power without connection to the vulnerable electric grid may be closer at hand than most people think. “Wireless power” will be…

Something crucial was missing from the first-ever global inventory of tax breaks for oil companies and other fossil-fuel subsidies when the Organization for Economic Cooperation and Development released it last fall. The report detailed all the subtle and not-so-subtle supports for production and consumption of oil, coal, and natural gas in 24 nations, including the world’s most advanced economies—all…

Comments Off on Stirling Engine: External Combustion Efficiency

One of the most unusual looking cars at this year’s Shell Eco-marathon Europe was testing out one of the oldest concepts for harnessing energy for motion: the Stirling heat engine. Team Schluckspecht from the University of Applied Sciences, of Offenburg, Germany, designed a vehicle that relied on external heating and cooling to drive pistons. The…

Comments Off on Valencia: Supercar Material for Super-Efficiency

Students from Spain’s La Universitat Politecnica de Valencia (UPV) do some final testing on “Urban Spirit,” the car they hope will help test new possibilities for fuel efficiency in Shell Eco-marathon Europe 2012. The Valencia team is one of 154 teams from some 20 countries gathered in Rotterdam this week for the student design, build,…

Comments Off on As Half the U.S. Contemplates Hydraulic Fracturing, First Liquefied Natural Gas Export Plant Approved

The Federal Energy Regulatory Commission on Monday approved the first large-scale liquefied natural gas export terminal in the lower 48 states despite record falling gas prices. Shipping from the $10 billion Louisiana plant is projected to begin as early as 2015. The Cheniere plant is the third liquefied natural gas plant in the works in Louisiana. Others are planned elsewhere in the country. The plants…

Comments Off on Purdue: Nearly Street-Legal, Powered By Sun

For the past 20 years, Purdue Solar Racing (PSR) has been designing and building a variety of solar powered vehicles. While these cars have all varied greatly in their designs and manufacturing processes,  Shell Eco-marathon’s urban concept category motivated PSR to enter into a completely unexplored realm with its eighth car, Celeritas. Urban concept vehicles…

Bringing together students majoring in mechanical, material, and aerospace engineering, as well as computer science, the Cal Poly Supermileage Vehicle Team combines all these disciplines to produce the most efficient vehicles possible. Last year, we took home the Technical Innovation Award at Shell Eco-marathon Americas for the onboard electronics and custom data acquisition and monitoring…
