Here in India we have elephants, plain and simple. It’s not like they’re running rampant in the streets or anything but where they do happen to be in larger numbers i.e. in the south of India, they could be a problem if provoked or in a bad mood because they woke up on the wrong side of the shed. In these remote cases things could get quite tricky as they aren’t like dealing with an annoyed canine that you can beat with a stick or throw a rock at in defence, unless you’ve got super strength of course so you can throw boulders and use trees. So in lieu of that, an inventor named Zachariah Mathew came up with a simple notion called his Violent Elephant Control Gear. It consists of a 7-kilogram box that’s strapped to one hind leg of the pachyderm and if the elephant get a little boisterous his controller or Mahout (technical name) can remotely activate the box’s system which fires a nylon belt across to the other leg binding them together. The box is a quite expensive though at $500 which makes it quite unreasonable for a local Indian who uses the animals for his trade, whatever it may be.
