In the drive to devise more efficient and durable batteries, one promising option uses carbon nanotubes, which not only can store far more electricity by weight than lithium ion batteries but also retain their charge for a much longer time...
Advanced transmissions, efficient engines and some smaller cars represent one strategy that would help an automaker meet the nation's first-ever greenhouse gas standard
Sometimes the pursuit of a great discovery is its own reward
Ford Motor Co. was in New York City on Tuesday (in anticipation of the upcoming International Auto Show that starts later this week) to show off its first attempt to go gas-free—the Transit Connect Electric. Scientific American went for a spin in the all-electric compact van (about the size of a minivan but with much more headroom) on the rain-slicked streets of New York to get some idea of what the vehicle looks, sounds and feels like...
In 1983, a Columbia University undergraduate named Barack Obama wrote an article, “Breaking the War Mentality,” for the school publication Sundial.
Although Americans are now recycling much of their discarded plastic, they may have to search for venues that accept durable items, such as ski boots, because many municipalities still do not accept articles made of hard plastic...
What the Frack? Natural Gas from Subterranean Shale Promises U.S. Energy Independence--With Environmental Costs [Slide Show]
Natural gas cracked out of shale deposits may mean the U.S. has a stable supply for a century--but at what cost to the environment and human health?
