Remembering the Real Space Cowboys - Space.com  We have been very lucky of late to have a great many books being written about the early days of the space program, often with direct input from those who took part. One of the latest offerings is "The Real Space Cowboys" (Apogee, $29.95), by Ed Buckbee and astronaut Wally Schirra. Ed Buckbee was a close colleague of Wernher von Braun for many years, serving as a NASA Public Affairs Officer at the Marshall Spaceflight Center in Huntsville, Alabama.     
Intelligent Workplace: The Office of the Future - Live Science  Workers in a heavily windowed living laboratory have a "right to daylight"—each desk is within 25 yards of natural light. Ceiling panels reflect warm daylight to work areas. Studies show that access to daylight improves worker productivity by 5 percent to 25 percent. Consoles at each station allow workers to control the flow of hot and cool air at their desk area. At the Intelligent Workplace, Hartkopf is collaborating with Bosch Siemens, Somfy and Cisco Systems on a fully automated building façade that will allow for control of daylight and glare so the building sheds heat in the summer when unoccupied to eliminate the need for spending electricity on cooling. In the winter, the system will allow the building to become its own heat collector and source. Hartkopf told LiveScience that his next large-scale office project at Carnegie Mellon is the Building as Power Plant. A project that will produce energy, not consume it, thanks to the combination of a biodiesel fuel cell along with recapture of shed heat from the generation of electricity, and collecting and redirecting heat from the soil and sun.

Q&A: Europe's Galileo project  - BBC  Europe is building its own satellite-navigation system called Galileo. BBC News looks at why such a network is deemed necessary when we already have the US Global Positioning System (GPS). The new Galileo system will offer five service levels (see below) and bring a step-change in performance. Since the first GPS satellite was launched in the late 1970s, sat-nav technology has evolved enormously. Galileo should offer greater accuracy - down to a metre and less; greater penetration - in urban centres, inside buildings, and under trees; and a faster fix. The Galileo system will also come with an "integrity" component - it will be able to tell users if there are major errors that could compromise performance. And when the US introduces the next generation of GPS, users will see a further jump in performance.
