Large scale exploitation of Solar energy is proposed by using floating devices which use solar energy to produce compressed hydrogen by electrolysis of deep sea water. Natural ocean currents are used to allow the devices to gather solar energy in the form of compressed hydrogen from over a large area with minimum energy transportation cost. The proposal uses a combination of well understood technologies, and a preliminary cost analysis shows that the hydrogen produced in this manner would satisfy the ultimate cost targets for hydrogen production and pave the way for carbon free energy economy.

This invention discloses a prime mover, preferably an electro-mechanical device (FIG. 2) with an end goal for generating electricity, which can operate even when the sun light based solar energy is not available. It comprises a wheel structure imparted with multiple arms (22) and arm loads (24) along with the feeder box (38) to cycle through the side tank (30). The feeder box regulates the arm movement within the feeder box (38) using the treaded guides (45). Due to the buoyant and gravitational forces the unbalanced arm loads (24) cause the imbalance in the wheel structure and rotate the entire wheel structure along the guided track. This prime mover can be used primarily for generating electricity by connecting it to an electrical generator (60).
