A method of generating power at remote oil pumping installations. A firsts step involves selecting a remote oil pumping installation that utilizes a prime mover with a rotating flywheel. A second step involves providing an electric generator having an input shaft. A third step involves coupling the input shaft of the electric generator with the flywheel, such that rotation of the flywheel rotates the input shaft of the electric generator, thereby generating electricity.
Méthode de production d'énergie à des installations éloignées de pompage de pétrole. Une première étape consiste à choisir une installation éloignée de pompage de pétrole qui utilise un appareil moteur doté d'un volant rotatif. Une deuxième étape consiste à fournir un générateur électrique doté d'un arbre d'entrée. Une troisième étape consiste à coupler l'arbre d'entrée du générateur électrique avec le volant, afin que la rotation du volant active la rotation de l'arbre d'entrée du générateur électrique, produisant ainsi de l'électricité.
