Jean-Paul Nyoma is a self-taught inventor from Cameroon who is best known for having conceived an energy accumulator in 2005. Despite the fact that he dropped out of school in grade 7, Jean-Paul Nyoma has nonetheless become an inventor. It must be said that he was passionate about electronics well before dropping out of school. Nonetheless, Jean-Paul Nyoma got an "informal" training in automobile electricity.


He got the idea of designing the energy accumulator in 2004, a period during which Yaoundé experienced a great deal of outages (blackouts). It is in 2005 that, from scrap, he manufactured his device that works like a standby generator. The performances of the accumulator have been improved several times. It seems that its starting range was 6h and should be 12h now.

The accumulator, which stores electricity and supplies it, among others, through a battery, is rated at 250 watts and could thus power as many devices like a computer, some lamps, a stereo, a TV set, etc. Jean-Paul Nyoma's device can accumulate energy in three ways which are: solar panels (photovoltaic), a car's engine or from an electric outlet. This invention was displayed to the public during the National Technology Days in 2008.

Jean-Paul Nyoma is also the inventor of a currency-counting machine that he manufactured in 2004. The idea came after he saw the pain faced by some casino operators who were manually counting coins. On the one hand, the device includes a selector that can be positioned between the numbers 10 and 2,000. On the other hand, one can select the type of coins that he wants. Hence, one can select 50 for the number of coins he wants and 100 for the type (category) of coins that he needs. The machine, in this case, will release 50 coins of type 100 CFA (or 5,000 CFA). Jean-Paul Nyoma has manufactured several models with different coins processing capacity (from 900 coins to 5,000 coins) and prices vary between € 213 and € 381.

Jean-Paul Nyoma, as a self-taught man, is giving us a great example showing that Africa's industrial development will need the contribution of all its talents, including those who have not graduated in science and technology fields.
