1. A power plant provided with a heat engine and with a gearbox and a reserve, the heat engine driving the gearbox, wherein the reserve is hydraulically connected via a hydraulic connection to the gearbox and to the heat engine to lubricate the gearbox and to increase a power of the heat engine without increasing a temperature of the heat engine or to reduce the temperature of the heat engine without reducing the power of the heat engine, the power plant including at least one main closure means between the heat engine and the reserve, and at least one secondary closure means between the gearbox and the reserve, the power plant including a control member for controlling the main and secondary closure means, the power plant including a mixer;
wherein the reserve comprises a first bottle configured to contain pure water and a second bottle configured to contain an intermediate solution;
wherein the control member is configured to control the mixer to only inject fluid from the first bottle into the heat engine; and
wherein the control member is configured to control the mixer to inject fluid from the first bottle and the second bottle as a fluid mixture into the gearbox.
