    • 2013 July-August, Henry Petroski, “Geothermal Energy”, in American Scientist, volume 101, number 4:
      Ancient nomads, wishing to ward off the evening chill and enjoy a meal around a campfire, had to collect wood and then spend time and effort coaxing the heat of friction out from between sticks to kindle a flame.
