Texas Wind Farm Uses NASA Radar to Prevent Bird Deaths : TreeHugger - 0 views
-
What do you do if you build a wind farm smack dab in the middle of a major bird migration route, and want to avert the anger of conservationists? Put up a radar system that's designed to shut down the entire thing when it detects a mass of birds on the way. That's what's been done at the 202 MW Peñascal Wind Farm in Texas: System Detects Birds Approaching Four Miles Away The system uses radar originally developed for NASA and the US Air Force to detect birds as far as four miles away, The Guardian reports. When it picks up the approaching birds, it analyzes the existing weather conditions and determines in real time whether those birds are in danger of flying into the blades. The system then automatically restarts the turbines when the birds have passed.

An environmentalist-sponsored report claims that by 2050, the United States could sever ties with coal and nuclear power, draw nearly all its electricity from renewable sources and cut its greenhouse gas emissions by more than 80% -- all with existing technology and with a net gain of 14 million jobs to the domestic economy. The report, commissioned by Greenpeace and the European Renewable Energy Council and conducted by Germany's equivalent of NASA, was released this morning at a press briefing in Washington. It is heavy on charts and supporting data and transparent on some key assumptions. And its sponsors call its findings "conservative." At its core, the report envisions a steep drop in the United States' energy use, both in absolute terms and compared with International Energy Agency predictions -- driven by strict efficiency standards. It also projects dramatic changes in the nation's electricity mix, with wind and solar power mushrooming to replace coal, oil and nuclear sources that would gradually go offline.

In an interview released today by Newsmax, Gov. Sarah Palin (R-AK) - Sen. John McCain's (R-AZ) newly minted running mate - was asked for her "take on global warming and how is it affecting our country." "A changing environment will affect Alaska more than any other state, because of our location," Palin said, adding, "I'm not one though who would attribute it to being man-made." DeSmogBlog notes that NASA and the National Academy of Sciences disagree:
Experiment Boosts Hopes for Space Solar Power | LiveScience - 0 views

A former NASA scientist has used radio waves to transmit solar power a distance of 92 miles (148 km) between two Hawaiian islands, an achievement that he says proves the technology exists to beam solar power from satellites back to Earth. John C. Mankins demonstrated the solar power transmission for the Discovery Channel, which paid for the four month experiment and will broadcast the results Friday at 9 p.m. EDT. His vision is to transmit solar power collected by orbiting satellites as large as 1,102 pounds (500 kg) to lake-sized receiver stations on Earth.

Twenty years ago NASA scientist, James Hansen told Congress that the use of fossil fuels was causing global warming. Earlier this year, Hansen and several co-authors published a paper titled Target Atmospheric CO2 that declared the amount of carbon reduction that needs to happen "if humanity wishes to preserve a planet similar to put to that on which civilization developed and to which life on Earth is adapted."
