1. A hybrid system for efficient free-energy generation from multiple renewable sources, comprising:
a giant turbine, positioned within a water flow, configured to convert kinetic energy from the water flow into electrical energy;
a plurality of piezoelectric nanogenerators integrated with the turbine by embedding the plurality of piezoelectric nanogenerators to surfaces of blades of the giant turbine, configured to convert mechanical energy from the water flow into electrical energy; and
a plurality of solar cells integrated with the turbine, configured to convert solar energy into electrical energy via a photo-electrochemical process, wherein the solar cells are mounted on top of or on the surface of the giant turbine, and are housed within a transparent shield to protect from environmental exposure,
wherein
the system combines and regulates electrical outputs from the turbine, the piezoelectric nanogenerators and the solar cells synergistically to provide a continuous and unified electrical output, regardless of real-time environmental conditions,
the piezoelectric nanogenerators are self-charging hybrid supercapacitors (SCHSC) constructed by sandwiching an activated carbon (AC) cathode and an activated carbon anode, with porous cellulose filter paper as a separator, and
the activated carbon used in the piezoelectric nanogenerators is derived from palm leaves, and is processed by soaking in aqueous KOH and washing with hydrochloric acid to achieve a neutral pH.
