Not that long ago, the world was supposed to be flat. Hardly a day passed without references to globalization and “borderless markets.” Many policymakers and business leaders jumped on the bandwagon, treating all interconnection among countries as equally beneficial. But this perception that “the world is flat” was so exaggerated that it is fair to call it “globaloney.” The last few years—of financial crises, weak growth, and mounting protectionist pressures—have demonstrated that the world is far less connected than it appeared to be. The real world is roughly only 10 to 25 percent globalized.
Second Wind: Air-Breathing Lithium Batteries Promise Recharge-Free Long-Range Driving--If the Bugs Can Be Worked OutTechnology :: News :: April 20, 2012 :: :: Email :: Print IBM-led research to create lithium-air electric vehicle batteries gets a boost from Japanese chemical companies toward the goal of 800 kilometers out of a full charge By Larry Greenemeier IN THE AIR: In this screen capture from an IBM computational simulation, scientists study the simulations of the interaction of an organic solvent electrolyte (propylene carbonate) with lithium ions (white) and oxygen near a surface of Lithium-peroxide (the planar structure near the bottom of the screen). Image: Courtesy of IBM Research-Zurich Researchers predict a new type of lithium battery under development could give an electric car enough juice to travel a whopping 800 kilometers before it needs to be plugged in again—about 10 times the energy that today's lithium ion batteries supply.
