Abstract

La présente invention concerne un système de moteur de reprise après catastrophe, qui se compose d'un moteur à combustion externe (3) simple se trouvant à l'intérieur d'un boîtier (1) scellable, flottant et imperméable. N'importe quelle matière combustible peut alimenter le moteur. Des espaces (40, 42) situés entre le boîtier et le moteur permettent le stockage de provisions de survie et d'outils utiles et échangeables. Le boîtier, une fois retiré, peut servir au stockage et au captage de l'eau, ou à la cuisine. La prise de force (18) partant du moteur et combinée avec un agencement simple d'une pompe, d'un générateur, d'un onduleur et d'une batterie peut être utilisée de manière interchangeable (ou en association) pour le pompage, la condensation, la stérilisation et la distillation de l'eau, et pour le fonctionnement ou la charge de dispositifs électriques. Le système fait office de moyen autonome pour la survie, la production d'énergie électrique hors réseau et le traitement de l'eau, indépendamment de la vitesse du vent ou des conditions solaires, en cas de catastrophe naturelle ou technologique ou d'interruption des services publics.
