Okey if I have an idea of a project that uses the stagnant water to produce electricity and I want?

Don't give your ideas away without legal protection (meaning a patent (not a good idea, because of the limited time frame) or a non-disclosure agreement (NDA). The best thing you can do is have a working model before you go for investment capital. You can work with a chemist (or whatever you need) who you can either pay, or who will work for an agreement for deferred pay or for a % of your future profits.
