very good idea.
But if u have it for ur project. do mention the following stuff in ur report. these things will be asked to u by ur teacher/project supervisor
1. system efficiency? what is the efficiency of the solar pond?
2. Area and Power spec. (how much big area wise a solar pond will produce 1 KW ) something like this
3. water heating stuff looks good (and so is done by similar solar water tube heaters) so whats the advantage of this system?
4. Any practical project in practice ? any where in the world? driving a turbine thru solar pond? IF yes mention it.
5. Cost Benefit analysis and PAYBACK period calculation
i must say. very good idea. just some points so that u dont miss ur precious project marks
P.S renewable energy is NEVER considiered by industry/Plant on large scale (because no one is willing to spend the Extremely high initial cost ) unfortunatelly this is the truth. industries are looking for their Profits but NOT the environment.
These Projects are usually done on GOVT level to supply electricity to villages/slum areas
