The invention relates to a renewable power and/or water generator with an absorption heat transformer (AHT) providing a heat pump, an Organic Rankine Cycle (ORC) for generating power, and a coupling between the AHT and the ORC to regenerate ORC rejection heat. The AHT consists of a low pressure evaporator and a vapour absorption binary (VAB) reactor that forms the coupling between the AHT and ORC. The VAB reactor includes an absorption section with an absorber heat exchanger and a distillation section provided by a rotating centrifugal unit that includes a flooded rotating packed bed.

There is disclosed an absorption machine comprising at least a first and a second compartment in fluid connection with each other, wherein the first compartment comprises at least one salt selected from the group consisting of LiBr, Lil, LiCl, Nal, and NH.sub.4I and wherein at least the first compartment comprises NH.sub.3 in an amount sufficient to form a liquid together with the at least one salt in the first compartment. Advantages of using the new mixture include that an absorption machine using a salt and NH.sub.3 can be made smaller and lighter with the same power. Further T can be improved. The vapour pressure of NH.sub.3 in the system can be kept relatively high.
