This is kind of psychological "medicine" of a shamanic nature to give people with little hope, hope, flawed as it is scientifically. This is classic cargo cult science, its quite natural human nature. Although associated with post WWII Pacific islands, here it is, quite at home in Africa, the birthplace of all humanity.
What can be done? People need to invest money in giving all people a decent public education with attention paid to basics like math and the physical sciences.
Not because it will necessarily lead to jobs, that quite possibly would never happen, because its the thing to do. We need a literate global society, everywhere.
In the past this young man would have been able to get access to basic training in electronics and might have been able to go to college and become an engineer. Instead of that corruption has likely become entrenched leading to the state of affairs he describes at 1:54 which I feel is likely true.
Note, I am not saying that his claims for this device have ANY validity at all, obviously at best at some point I suspect he might have built a battery and measured the current produced, but then my guess is the project self-transformed into something else..
However, at the beginning, I suspect he started out trying to, and deserves to learn electronics. The real kind. Electronics can be valuable as a way of constructively occupying ones time. Even if the huge factories filled with workers are vanishing, even in the low wage countries.
Can we really blame him for trying to inspire people to be innovators, somehow? Instead of as he articulately puts it, become drunks or thieves?
How many members do we have here from Africa, apart from South Africa or the Arab nations around the Mediterranean? I haven't seen that many.
