BOW WOW! ... As the name might imply, Aris z Kaplickeho hamru is no ordinary dog. In fact, Aris is a crime fighter with an extensive record of capturing thieves, burglars and assailants and bringing them to justice. Once, Aris tracked down a murder suspect who was captured after a manhunt by numerous agencies. For the Palo Alto Police Department, Aris is also a public-relations asset, a past guest at Rotary Club and Boy Scout meetings and a participant in the department's Citizen's Police Academy classes. But after six-and-a-half human years in the department, the popular police-service dog retired in July. On Tuesday night, Aris will receive a bureaucratic scratch on the back when City Council passes a resolution citing the above accomplishments and recognizing the retiring canine for "his commitment to the community and his consistent efforts."
WINDS OF CHANGE ... What's the cleanest way to meet the world's energy needs? The answer to this question is blowin' in the wind. That's according to new research from Stanford University Professor Mark Jacobson and the University of Delaware Associate Professor Cristina Archer, who recently considered the question and determined that 4 million turbines, each 100 meters high, could provide more than half of the world's power demand without significant negative effect on climate. Jacobson, a professor of civil and environmental engineering, and Archer, an associate professor of geography, physical ocean science and engineering, would place about half of these turbines over water. The rest would be installed on land and scattered around high-wind sites across the globe, places like the Gobi Desert, the American plains and the Sahara. "We're not saying 'put turbines everywhere,' but we have shown that there is no fundamental barrier to obtaining half or even several times the world's all-purpose power from wind by 2030," Jacobson said. "The potential is there if we can build enough turbines." But, he added, the world still has a long way to go. "Today we have installed a little over 1 percent of the wind power needed," Jacobson said. To be sure, the professors' vision of millions of turbines powering the world isn't without its complications. The computer model they used calculated wind power potential but did not factor in real-world barriers such as economics or societal views toward wind power.
