• Metals with Memories: The Changing Shapes of Modern Alloys | Scienceray
  – "ubsequent experiments demonstrated that most alloys can be trained to form two different shapes, one in each phase, by repeated heating, cooling, deforming, and reheating. Once trained, a shape-memory alloy “remembers” both shapes and can change from one to the other indefinitely."
  – "A nitinol engine of the future could be powered by making use of the distinct layers of water of different temperatures that exist in deep lakes and reservoirs: the nitinol rods would perform like pistons as they react to temperature changes. With the approaching depletion of the fossil fuels on which modern technology depends, shape-memory alloys may hold a key to future energy requirements."

• Curing the Post-Copenhagen Hangover : Climate and Capitalism
  – "In Copenhagen, the world’s richest leaders continued their fiery fossil fuel party last Friday night, ignoring requests of global village neighbors to please chill out.

  Instead of halting the hedonism, Barack Obama and the Euro elites cracked open the mansion door to add a few nouveau riche guests: South Africa’s Jacob Zuma, China’s Jiabao Wen (reportedly the most obnoxious of the lot), Brazil’s Lula Inacio da Silva and India’s Manmohan Singh. By Saturday morning, still punch-drunk with power over the planet, these wild and crazy party animals had stumbled back onto their jets and headed home."

  – "So if only two things were accomplished in Copenhagen, they were the unveiling of Pretoria, Delhi, Beijing and Brasilia as willing criminal accomplices to the Washington/Brussel/Tokyo/Melbourne/Ottawa axis, and the rise of Climate Justice Action, Climate Justice Now!, 350.org and parallel movements whose hundreds of thousands of protesters swarmed streets of the world’s cities."
