Ion engine could one day power 39-day trips to Mars - space - 22 July 2009 - New Scientist - 0 views

  •  
    As I mentioned it into my thesis, this engine bridges the gap between chemical and low-thrust propulsion systems. To be more specific: Isp should vary between 1000 and 30000s, and the thrust amplitude should reach up to 1200 N. It is interesting to see that the concept is actually moving forward ...

Better world: Take Friday off… forever - 15 September 2009 - New Scientist - 0 views

  • According to Facer, it was the crash of 1929 that led to the five-day week. "Before that it was common to work six-day weeks with 12 to 14-hour days. When the Great Depression hit, the idea was to share work around to get more people into employment." During the next big financial crisis in the 1970s, there was much talk of moving to a four-day week, but for a variety of reasons that didn't pan out. "Things are different now," says Facer. "I wouldn't be surprised if we could get 50 per cent or more of the workforce working four-day weeks in the next few years." Next up: the three-day week.
