...share their excitement about the cool things that await them in the future - maybe even as a holiday gift. Some, however, were troubled by the ethical implications of the cloned dog Snuppy I truly enjoyed your selection of the best new inventions [Nov. 28]. I liked the ENV hydrogen-powered motorcycle and the Shift tricycle, whose rear wheels move closer together at higher speeds and separate for balance at slower ones. But I was most impressed by the LifeStraw [a drinking tube with powerful filters that can prevent waterborne infections, which kill millions of people in the developing world...

I've traveled to areas where clean water is not a given, so I can appreciate the LifeStraw's value. Thank you for opening eyes around the world to this wonderful device. Rathika Ramadoss...
...painstaking account of the making and breaking of an intricate man. Oppenheimer directed the successful U.S. effort to develop an atomic weapon during World War II. But after the war his opposition to the push for an even bigger weapon, the hydrogen bomb, helped set in motion the events that led to his being stripped of his government security clearance. The authors show the ways in which Oppenheimer was complicit in his own destruction, but never lose sight of the ugliness of the process...

...Machine Inventor: Intelligent Energy Availability: In early 2007, for less than $10,000 To Learn More: envbike.com The ENV bike looks like a muscular motorcycle but runs more like a moped. Weighing in at 200 lbs., the aluminum bike travels at speeds of up to 50 m.p.h. on its hydrogen-powered fuel-cell engine. Project director Andy Eggleston says that proprietary technology allows the fuel cell to produce more energy than is typical. The ENV runs silently on a 5-oz. canister of hydrogen that costs about $4 and can power the bike for 100 miles. The drawback? California...
