...Jarvik 2000, by contrast, has a tiny rotary pump--sort of a coronary Wankel engine that spins rather than squeezes. That might eliminate the pulse, which some physicians think could wreak unpredictable havoc on the body, except that the Jarvik is designed to replace only the left ventricle; the right still provides a beat...
...economy has rolled merrily along, doing what supposedly could not be done. True, a sudden March flare-up in consumer prices--far larger than could be blamed on gas-pump inflation--indicated that labor costs may at last be starting a troublesome rise. Yet employment figures for the same month make it clear that the U.S. is a long way from running out of workers.

Even after subtracting temporary Census hiring and adjusting for seasonal quirks, job gains continued...
That's extraordinarily good news for China, whose gigantic size, rapid industrialization and huge domestic coal reserves threaten to pump cataclysmic amounts of CO2 into the air over the next century. While scaling fuel cells down to fit inside cars and trucks has been a challenge, scaling them up or linking them together to run factories and power plants should be no problem...
...danger in pulling hydrogen from fossil fuels is that it leaves carbon dioxide behind. If the CO2 is simply vented into the atmosphere, global warming will be as big a problem as ever. There is an alternative though: pump it into the ground. In Norway, for example, the energy company Norsk Hydro is building a power plant that will be fueled with hydrogen drawn from natural gas. The CO2 that's left over will be reinjected into an oil field on the continental shelf. Not only will this take the carbon dioxide out of circulation but it will also pressurize...
...know such government pump-priming works; it's why so many of us have computers today. America's computer companies began learning to produce today's affordable systems during the 1960s while benefiting from subsidies and guaranteed markets under contracts with the Pentagon and the space program. And the cyberboom has fueled the biggest economic expansion in history...
