Abstract: A system for producing and distributing electrical energy over an electrical network of a geographic area, includes a first entity for generating electrical energy, which operates in a steady state and generates at least a portion of the electrical energy; a second entity for intermittently generating the electrical energy from renewable energy; a third entity, which is capable of operating in a load-following state, the system being sized such that the profile of the change in total energy potential of the geographic area over the span of one year, corresponding to the sum of the profile of the change in the amount of electrical energy distributed by the main entity and the profile of the change in the amount of electrical energy generated by the second entity over the span of one year, is less than the profile of the change in the demand for electrical energy of the network.

Abstract: A mobile mixing device for at least two products coming from storage containers in barrels equipped with internal kneading means, which can be rotated by a kneading head, via a disconnectable coupling, wherein the device comprises a fixed stand having two receptacles able to receive the barrels and a turret supported by the stand, so that it can rotate about a vertical axis, said turret having the storage containers, the kneading head, at least one tube connecting each of the storage containers to the kneading head and means for vertically displacing the latter an upper position permitting a rotation of the turret in order to bring the said head successively above each of the barrels placed in the receptacles of the stand and a lower position in which the kneading means of the corresponding barrel are connected to the kneading head by said coupling.
