A Kenyan self-taught innovator David Gathu (C) 29, using a neuro load bio potential head set receiver he illustrates how their recently invented robotic arm is operated at their makeshift workshop in Kikuyu, Kiambu, north of Nairobi, Kenya, 26 January 2021. Neither Gathu nor his partner Moses Kiuna 26, were able to pursue higher education, because they could not bear the university costs, and have spent years developing technological innovations to solve problems in their community, from safety to health, and now, in the middle of a pandemic, they have developed a device to disinfect surfaces and spaces of the covid-19. By using raw materials from other discarded appliances they have in recent years innovated numerous technological solutions such as a robotic arm or a security application, but in recent months, they have focused their efforts on developing a “disinfectant machine”. The device, which is still in the prototype phase, oxidizes oxygen molecules to convert it into another gas, ozone, which has a great capacity as a disinfectant, Gathu details, while doing a demonstration of its operation.
