Human-animal conflict along the borders of Gabon's National Parks can lead to the poaching of protected species. Elephants stampede through traditional fences and trample village plantations - affecting the food supply and resulting in angry villagers. 
The electric fence shown below offers a humane resolution protecting animals and plantations alike. 
Constructed of a car battery, metal wire, zip ties, and local bamboo, this fence provides a surprising and 
memorable "zap" to anything that comes in contact. 
Above, my team and I demonstratie how the electric fence works by joining hands and feeling the "zap."
Below is another fence demo done for our 2016 workshop at the Albert Schweitzer Hospital
 in Lambaréné, Gabon.
