NASA Puts the "Green" in Its Other Mission: Developing Revolutionary, Energy-Efficient Airplanes

Source: Scientific American.com: Earth & Environment - Posted: July 26, 2010 11:00:00 AM

It took 24 years for humankind to advance from the first powered flight in 1903 to Charles Lindbergh's famous crossing of the Atlantic (and even less time for the U.S. space program to go from launching the first American astronaut into suborbital space to landing men on the moon). NASA officials are now hoping 25 years into the future is enough time for the nation's aerospace engineers to come up with more ecofriendly airplanes. [More]

If there's one thing more potentially contentious than the international politics of global warming (which the world has spent at least the past 20-plus years dithering about), it's the politics of the most radical suggestion to solve it: geoengineering . After all, he who controls Earth's thermostat may well control Earth. And what's good for one nation (i.e. Bangladesh and its shoreline prefer today's climate, fearing sea level rise under a warmer one) may not be good for another (i.e. Russia might enjoy a balmier Arctic Circle).
