Dans cette petite contr\u00e9e de la Guin\u00e9e-Conakry, \u00e0 Bolodou, les habitants n’auront plus besoin d’utiliser des lampes \u00e0 pile pour s\u2019\u00e9clairer la nuit, gr\u00e2ce au projet fou d\u2019Ibrahima Tounkara. <\/strong><\/p>\n

Ce jeune professeur de Math\u00e9matique a d\u00e9cid\u00e9 de lancer un projet avec toutes ses \u00e9conomies pour fournir de l’\u00e9lectricit\u00e9 \u00a024h\/24 \u00e0 90 foyers de son village. \u00a0Ce projet repose sur la construction d\u2019un micro-barrage sur un petit torrent traversant la localit\u00e9. L\u2019installation produit aujourd\u2019hui une puissance de 9 kW.<\/p>\n

Depuis mai dernier, Ibrahima Tounkara est devenu un h\u00e9ros dans son village natal. Ce touche-\u00e0-tout a r\u00e9ussi \u00e0 installer le barrage hydro\u00e9lectrique sur le torrent Gbasso, qui traverse Bolodou. Cette installation, pour laquelle il a investi \u00e0 partir de ses fonds propres 50 millions de francs guin\u00e9ens ( soit 4 650 euros) lui a pris 1 an de dur labeur. C’est un succ\u00e8s pour ce projet sur lequel personne n\u2019osait parier \u00e0 ses d\u00e9buts.<\/p>\n

\"Guin\u00e9e:<\/p>\n

\u00ab\u00a0Dans le village, on m\u2019a d\u2019abord pris pour un fou lorsque j\u2019ai expliqu\u00e9 que je voulais construire un barrage hydro\u00e9lectrique. Mais j\u2019\u00e9tais persuad\u00e9 que je pouvais trouver une solution pour cr\u00e9er de l\u2019\u00e9nergie \u00e0 Bolodou. J\u2019y ai grandi, ma famille y vit, et j\u2019ai toujours \u00e9t\u00e9 sid\u00e9r\u00e9 que rien ne soit fait pour le d\u00e9veloppement de ces petits villages qui sont compl\u00e8tement coup\u00e9s du monde.\u00a0\u00bb <\/strong><\/em>dit-il<\/p>\n

\u00ab\u00a0En plus de mon travail de professeur de math\u00e9matiques, je me suis toujours int\u00e9ress\u00e9 \u00e0 la production d\u2019\u00e9nergie. J\u2019ai d\u2019abord lanc\u00e9 un projet autour des panneaux solaires. J\u2019ai appris \u00e0 les installer, ce qui m\u2019a permis de gagner de l\u2019argent en proposant mes services aux familles qui en voulaient un chez elles. J\u2019ai \u00e9galement construit une petite cabine de rechargement de t\u00e9l\u00e9phones qui marche \u00e0 l\u2019\u00e9nergie solaire \u00e0 Bolodou. Petit \u00e0 petit, j\u2019ai fait des recherches sur l\u2019\u00e9nergie hydro\u00e9lectrique. \u00c0 Bolodou, il y a de petites chutes d\u2019eau qui ne sont pas du tout mises en valeur.<\/strong><\/em><\/p>\n

En mars 2016, j\u2019ai achet\u00e9 un smartphone pour avoir acc\u00e8s \u00e0 Internet et je me suis renseign\u00e9 sur le fonctionnement des barrages. J\u2019ai fini mes recherches en d\u00e9cembre 2016 et j\u2019ai entam\u00e9 les travaux de construction. Gr\u00e2ce \u00e0 des sch\u00e9mas et des vid\u00e9os, j\u2019ai fabriqu\u00e9 une petite turbine reli\u00e9e par une poulie \u00e0 une dynamo, qui transforme l\u2019\u00e9nergie m\u00e9canique en \u00e9lectricit\u00e9.\u00a0\u00bb<\/strong><\/em><\/p>\n

\"Guin\u00e9e:<\/p>\n

Pour sa turbine, \u00a0Ibrahima Tounkara mettra en place un micro-barrage pour la faire fonctionner. Il est parti d’abord de l’\u00e9laboration d’un canal d\u2019amen\u00e9e, qui d\u00e9vie l\u2019eau du torrent de son lit pour la conduire vers une chambre d\u2019\u00e9quilibre, c\u2019est-\u00e0-dire un bassin qui sert \u00e0 r\u00e9guler le d\u00e9bit. La quantit\u00e9 d\u2019eau n\u00e9cessaire est ensuite envoy\u00e9e dans une conduite forc\u00e9e \u2013 un autre canal \u2013 qui draine l\u2019eau \u00e0 la centrale, o\u00f9 se trouve la turbine. Pour r\u00e9aliser tout cela, il s’est fait simplement aid\u00e9 par un ma\u00e7on du village, et pour la suite il a d\u00fb se d\u00e9brouiller avec les moyens de bord.<\/p>\n

Aujourd’hui ce barrage produit 9 kW d\u2019\u00e9lectricit\u00e9. Ibrahima Tounkara propose aux habitants de payer 2 000 francs guin\u00e9ens par semaine soit\u00a0 19 euros pour avoir acc\u00e8s \u00e0 l\u2019\u00e9lectricit\u00e9. C\u2019est beaucoup moins cher pour eux que d\u2019acheter des piles pour allumer des torches \u00e9lectriques ou se procurer de l\u2019essence pour les lampes \u00e0 p\u00e9trole. Cet argent me permet de prendre en charge les frais d’entretien du barrage.<\/p>\n

L\u2019\u0153uvre du jeune professeur ne passe pas inaper\u00e7u. Il a \u00e9t\u00e9 a d\u00e9j\u00e0 \u00e9t\u00e9 contact\u00e9 pour r\u00e9aliser ce type d\u2019installation dans d\u2019autres villages.<\/p>\n

En Guin\u00e9e, seul un habitant sur quatre \u00e0 acc\u00e8s \u00e0 l\u2019\u00e9lectricit\u00e9,\u00a0selon les derni\u00e8res donn\u00e9es de la Banque mondiale. En avril dernier, le gouvernement a fait conna\u00eetre son ambition de connecter 721 000 foyers d\u2019ici \u00e0 2020. Mais la population s\u2019impatiente et multiplie les manifestations, souvent tr\u00e8s tendues. Le 13 septembre, deux jeunes hommes ont \u00e9t\u00e9 tu\u00e9s et une cinquantaine de personnes bles\u00e9es \u00e0 Bok\u00e9, une ville situ\u00e9e \u00e0 300 km au nord-ouest de la capitale Conakry, dans des affrontements avec la police.\u00a0Les manifestants r\u00e9clamaient d\u2019\u00eatre raccord\u00e9s au r\u00e9seau de distribution d\u2019eau et d\u2019\u00e9lectricit\u00e9. Le pays dispose pourtant d’un important potentiel hydro\u00e9lectrique,\u00a0estim\u00e9 \u00e0 6 000 MW, mais qui n\u2019est \u00e0 ce jour mis en valeur qu\u2019\u00e0 hauteur de 2 %.<\/p>\n","protected":false},"excerpt":{"rendered":"
