A new way of generating electricity

Claudio, you have a very nice website there, clean and with nicely done drawings. 

Not to put a spanner in the works, but you might do better spending less money on your website and paying your engineer a little bit more such that he can finish the calculations with enough detail, including ALL friction factors and a thermodynamic model of something more realistic than the ideal adiabatic process you have chosen to "prove" it works.  I do suspect that you will be able to see for yourself that the laws of thermodynamics are quite troublesome to circumnavigate.  That said, good luck in minimizing those adverse effects.
