    Four-Day Planet by  H. Beam Piper: 
      Science Fiction Inventions, Technology and Ideas
    Enjoyable novel by Piper; the most interesting main character is the planet Fenris. Days that last for 2,000 hours and four days per year; too hot or too cold. This book recalls some of Heinlein juveniles of the fifties. Select
      an invention: 
    
         Recording Radio  A handheld device that both recorded sound and transmitted it live to a remote broadcasting location.
