Projects included:

  • A bacterial fuel cell that generates electricity from waste material such as urine.
  • A wind turbine made of junk parts.
  • A sand- drawings robot.
  • A solar freezer.
  • The Car Oven that uses heat accumulated inside a car for cooking.
  • Low cost geodesic domes constructed from recycled materials.

  • Kite electricity making electricity out of kite movements.

In addition to the projects the camp featured an exciting range of workshops and discussions addressing sustainability issues. is the brainchild of Ilan Graicer and Gilli Cegla, both serial high-tech entrepreneurs with extensive resumes. The two essentially decided to hold an “unconference”, in which each participant actively engages in shaping the character of the event. Everything ranging from determining the agenda through cooking dinner is the outcome of collaborative teamwork by the attendees themselves. After having organized numerous “unconferences”, and having generated dozens of ideas and several start-ups, they sought to bring this extraordinary method of work into the realm of green innovation.
