<p>An economic process is provided for the simultaneous prodn. of sources of energy, fresh water and by-prod(s) from aqs. materials (I) and an energy source such as solar energy. The process comprises heating (I) to boiling pt. in a closed tight space to which (I) can be fed and from which the water vapour produced and evaporation residue can be recovered. The water vapour formed is sent, under pressure, to a turbo-alternator turbine for generating electricity, and is then condensed to fresh water on leaving the turbine. The evaporation residue of (I) is recovered as by-prod. According to the novel feature, the water vapour is also sent, either directly, or on leaving the turbine, over iron heated to 800 degrees C to be partially reduced to hydrogen which is recovered. The water vapour which has not been reduced by the iron is condensed to water for various uses. The initial energy source used for heating (I) and the water vapour to be reduced is, apart from solar energy, any other known source, even a non-economical one, e.g. coal from deep mines. The condensed water may be used for drinking, watering, irrigating or heating. The evaporation residue may be used for producing fuels opt. after further processing. The ferric oxide formed in the reduction of the water vapour may be used as oligo-element in agriculture.</p> |
