Tsengue Tsengue is an inventor from Congo-Brazzaville who heads Challenge Futura, an industrial company specialized in the fields of energy, water and agri-food. This engineer from Ecole Centrale de Paris has a great deal of experience in oil production and refining, construction, electrical energy production, sugar production, as well as in the processing and marketing of agricultural products.

One of Tsengue Tsengue’s inventions is a cassava production line which enables the mechanical preparation of chikwangue or cassava bread. This device consists of a peeler, a grinder and a dough mixer. At the end of the production line, the dough is cut into cassava bread and packed by hand in plant leaves. This device increases, in a more hygienic way, the production of chikwangue while continuing to meet the culinary expectations of consumers. The selling price of the equipment varies between 1 and 6 million CFA francs (1,524 and 9,146 euros) depending on models.

Tsengue Tsengue and his team have also developed, a few years ago, a marine current turbine (tidal turbine) of 15 kilowatts manufactured entirely in Congo. A marine current turbine is a submarine turbine that uses the kinetic energy of ocean currents or rivers, just like a wind turbine uses the kinetic energy of the wind to produce electricity. This marine current turbine could be used to manufacture mini hydro-electric dams. Tsengue Tsengue has also worked on a feasibility study of the Mutsora hydro-electric dam in North Kivu (Congo - Kinshasa) that was financed by the European Commission.

Another invention made by Tsengue Tsengue is an adjustable solar dryer for which he received, at the 35 International Exhibition of Inventions of Geneva, the gold medal from the World Intellectual Property Organization (WIPO) awarded to an inventor from a developing country, and the Swissolar prize from the Swiss Association for Solar Energy.



Tsengue Tsengue owns patents filed with OAPI (African Intellectual Property Organization); the same organization that allowed him to take part in the 35 International Exhibition of Inventions of Geneva.
