Former NASA astronaut, Dan Barry has seven hours of spacewalking time to his credit. He tried whistling during his spacewalk on STS-96 in May 1999. "It wasn't something I hadn't planned — I thought of it on the fly. It turned out that it didn't work." he said. "You can't whistle because the air pressure in the suit is only 4.3 [pounds per square inch], and normal atmospheric pressure is 14.7 psi, so there are not enough air molecules blowing by your lips to make a sound," he said.
Seen on Blue's News."

From the article: Within five years, solar power will be cheap enough to compete with carbon-generated electricity, even in Britain, Scandinavia or upper Siberia. In a decade, the cost may have fallen so dramatically that solar cells could undercut oil, gas, coal and nuclear power by up to half. Technology is leaping ahead of a stale political debate about fossil fuels. (http://www.telegraph.co.uk/money/main.jhtml?xml=/ money/2007/02/19/ccview19.xml)

Milwaukee's_Best writes "Skype has just asked the FCC to force wireless phone companies to open their networks to all comers. Skype essentially wants to turn the wireless phone companies into just another network of the kind currently operated on the ground. This would require carriers to allow any phone to be used on their networks, and for any application. Users would simply purchase a voice or data plan (though these could easily converge into a data plan if VoIP calling is used) and then use the device of their choice to access the network of their choice. Think of it as network neutrality for cell networks. Given the competition that exists within the industry, is this needed?"
