Are carbon nanotubes safe or harmful?

Carbon nanotubes, or CNT, are being used to make products stronger, lighter, faster, and more efficient. But are they safe? A growing body of research is raising concerns over the hazards presented by some forms of the material. As ever though, the risk to health depends on who is exposed to what

Carbon-Fiber Car of the Future

In this video segment adapted from NOVA, hear physicist and energy expert Amory Lovins explain how to make more efficient cars by making them lighter and more aerodynamic. Explore how the use of carbon fiber can reduce weight without reducing size or durability, and learn about some manufacturing ch

Environmental impact of cruise ships

NABU has calculated that one cruise ship produces more sulfur dioxide per day than 300 million cars. The particulate matter pollution is equivalent to about one million cars. In addition, one cruise ship produces more carbon dioxide per day than 80,000 cars. On top of that, in many ports there is no
