Thats quite some innovation, the type that solves problems.
But on the flipside and perhaps unrelated to your post, i have noticed through my interaction with people from other parts of the world that many are really ignorant about Africa, courtesy of all the stuff the Western Media has to say about Africa (surely no good thing, just war, hunger, disease, smh). Well, its not their fault either, imagine someone asking if we had TVs in Africa, like wtf??? Africa aint half as bad as most people think it is. Well story for another day.
Well, great innovation like i said, but the exclusive mention of Africa brought up that thought.
