The power barn system provides a way to eliminate greenhouse gas (GHG) emissions from livestock. The power barn system seals and traps the methane gas that is emitted from the livestock and converts the methane into electric power and carbon dioxide to enhance plant growth. The power barn system uses PV solar arrays and plastic sheeting to make sealed, airtight structures. The carbon dioxide is provided to one or more sealed greenhouse areas. The plants use the carbon dioxide and release oxygen, thereby completely eliminating greenhouse gas emissions from livestock. The power plant uses the methane at peak times at night while solar panels supply power during the day producing zero emission and 24/7 electricity at better than market rates.

A water reservoir system for generating, accumulating, storing, and releasing electrical energy comprises a reservoir wall built in a shallow body of water such as a sea or an ocean with a height exceeding the outside water level by about 10-25 m, thereby defining an interior of the water reservoir. Excess electrical energy from other renewable sources of electricity such as wind, solar power, or supplied by a local power grid is used to operate water pumps to fill the interior of the water reservoir with water during times of peak supply of electricity. Water is drained from the water reservoir to the outside body of water and generates electrical energy by flowing over a plurality of water turbines, thereby generating electricity and supplementing electrical power for the local power grid during times of high demand. Additional interior sources of renewable energy may be used to supplement external sources of electrical power in operating the system of the invention.

The present invention relates to an electric power generating system for vehicles. The system includes at least one wind turbine positioned to capture incoming air which is coupled to a wind generator for converting into electric power. The system has solar panels installed on the exterior surface of the vehicle such as trailer of a semi-truck for absorbing solar energy and converting into electric power. The electric power produced by the wind generator and the solar panels is stored in a battery pack for providing electric power to the electric battery of the vehicle. An emergency generator provides electric power to the vehicle when the power of both the electric battery and the battery pack is insufficient. The system slows down the depletion of battery charge, thus enabling the vehicle to stay on the road for a longer duration and improves overall charging experiences for the electric vehicle.
