home power generation

I know there is a similar thread here but failed to find it....anyways i have alot of ideas about genwratig my own power from multiple sources....sterling engine and parabolic lense...hydo electric and wind....anyone having any luck? I mainly use electric for refridgeration and internet...charging phone ect...not a mass user.... i have been spending alot of brain energy on working out a pressure storage instead of a battery backup....using power to compress air and bleeding it off to spin a turbine latwr rather then have tons of batteries....there is a similar functioning systwm herw in hawaii...made from 50gal drums and copper pipe. Leta hear your ideas and thoughts.
