    When it comes to climate change, Bangladesh--with 140 million mostly poor residents and low-lying coastal geography--is among the most vulnerable nations on Earth. As part of the country's effort to prepare and adapt, Bangladesh government agencies are attempting to take global projections of climate change and turn them into highly local predictions.

  • Ramping up the use of renewable energy would lead to the "rape of nature", meaning nuclear power should be developed instead.

    To get a sense of what seven years of drought in the Colorado River basin looks like, all you have to do is gaze out at Lake Mead from the top of the dam here and view the 108 feet of brightly colored earth below the familiar red walls rising from the water.

  • A space elevator would essentially be a long rope made of nanomaterials, stretching from Earth to a counterweight at geosynchronous altitude, about 22,000 miles (35,406 kilometers) above Earth's surface. Special craft, like elevator cars, would travel along the ribbon, carrying people and goods into space in a matter of days.

  • An innovative program to build prototypes of multiple designs of small modular reactors (SMRs) at the Savannah River Site (SRS) is getting off to a rocky start. The anti-nuclear group Friends of the Earth (FOE) is charging that the Department of Energy (DOE) is trying to avoid having to submit the projects to the Nuclear Regulatory Commission (NRC) for licenses to build them.

  • Here is the Brad Edwards interview. Dr. Edwards received his PhD in physics in 1990, and worked at Los Alamos National Lab for 11 years. After leaving Los Alamos, Dr. Edwards has dedicated his career to researching and developing the space elevator concept. All of his research indicates that the space elevator concept is valid and feasible. He currently heads a company called Black Line Ascension, which is actively promoting the space elevator concept. He has published several books on the space elevator, including The Space Elevator: A Revolutionary Earth-to-Space Transport System, and Leaving the Planet by Space Elevator.

  • Where's the coldest spot in the universe? Not on the moon, where the temperature plunges to a mere minus 378 Fahrenheit. Not even in deepest outer space, which has an estimated background temperature of about minus 455°F. As far as scientists can tell, the lowest temperatures ever attained were recently observed right here on earth.

    Even on the moon, superconductors would need to be cooled.

  • MAGINE having to call an IT help desk to fix your central heating when it breaks down. That's not such a bizarre notion if a plan by engineers at IBM in Switzerland goes ahead. A cooling system they have developed allows the waste heat from computer chips to be put to use for domestic heating.

electricity nuclear technology heating

shared by Hans De Keulenaer on 11 Apr 08 - Cached
  • Electricity is usually made using nuclear power by heating steam to rotate turbines that generate electricity. But beginning in the 1960s, the US and Soviet Union used thermoelectric materials that convert heat into electricity to power spacecraft using nuclear fission or decaying radioactive material. The Pioneer missions were among those using the latter, "nuclear battery" approach.

    You may not realize how often you use batteries until you have to operate for a few hours without electricity. Batteries are great at keeping a charge in our mobile devices, but the components that help generate these charges wreak havoc in landfills. You can use Earth911 to find out where to recycle batteries for a number of devices, including your car and cell phone. Here's eight ways to optimize your battery use so you'll create less waste in the first place.
