The use of pressure-retarded osmosis for increasing the solar pond efficiency

Article Abstract:

The solar radiation trapped in the solar pond (SP) is converted into thermal energy and recovered from the solution using a direct osmosis process. Through this process, known as pressure-retarded osmosis, an osmotic membrane is created, thereby converting the osmotic pressure of the solution into hydrostatic pressure. This pressure is in turn converted to mechanical energy through a conventional hydroturbine system.

Comments on "A new look at the maximum conversion efficiency of black-body radiation." (includes related article on the formula for continuous conversion of black-body radiation energy into mechanical energy)(Letter to the Editor)

Article Abstract:

The thermodynamics of radiant energy conversion into work according to Stephen Kabelac is not a new concept. His equation (16) is applicable to photothermal converters and is directly derived from Carnot's formula for the maximum efficiency of a traditional heat engine. Kabelac's recommended method for deducing formula (16) is likewise not a new idea since it is merely a derivation of the traditional formula.
