...runner's stride is not perfectly efficient. Ankles waste energy???much more, it turns out, than Pistorius' J-shaped blades. He can run just as fast using less oxygen than his competitors (one describes the sound Pistorius makes as like being chased by a giant pair of scissors). On Jan. 14, following the findings of the researcher who evaluated him, the IAAF disqualified Pistorius from Olympic competition. He is expected to appeal, arguing that the science of advantage is not that simple. Tom Hanks is interested in his life story. No matter what happens next, Pistorius is changing the nature...
...Spain, and in rapidly growing China nearly 20% of all venture capital was channeled into clean companies in 2006 - double the percentage in the U.S. Green start-ups searching for cash "have gone from a desert to drinking from a fire hose," says Nancy Floyd, head of the alternative energy???focused venture-capital firm Nth Power, which also has invested in Imperium Renewables. Like Tobias, Silicon Valley stalwarts who helped power the IT revolution see clean tech as an investment opportunity that could have no ceiling - and that comes with the side benefit of potentially saving the world.

That capital is already paying off. Revenues for companies in solar energy, wind, biofuels and fuel cells surged from $40 billion in 2005 to $55 billion in 2006, according to the research group Clean Edge. Clean energy???related companies raised over $10.3 billion in ipos in 2006, up from $4.3 billion in 2005, and hot new companies such as First Solar, whose stock jumped from $25 to $215 in the past year, are angling to become green Googles. In turn, green venture capital in the U.S. is projected to rise to $18 billion by 2010, according to Nicholas Parker...
...they? That raises an interesting Darwinian problem: Which group is stronger; which is fitter? The young who demonstrated their moral energy???as well as their social clout, often enough?by avoiding the draft, by staying in college or heading across to Canada? Or the so-called suckers who got caught in the draft? (Were they stupid? Patriotic? Defenseless?) Those suckers passed through a physical and moral test that the others (however principled their refusal) will never know...
...Mann Intermediate School, there was an impressive array of energy projects. One seventh-grade student, Chris Bonagura, 13, built a working model of a solar-heated home. He was Inspired when he became cold one night on an environmental field trip. Says he: "I thought about heating and solar energy???no wasted coal or oil or garbage like that, you know. It's just the sun." At Dwight Morrow High School in Englewood, N.J., Mike McGlue, head of the science department, helped set up an energy program. Says he: "We talk about students' homes?insulation, where the house should...
