A gravity-driven electricity generating device includes a first power unit having a first swaying frame pivoting from a first position to a second position to output a first power, thereby moving a first end of a pressing board downward and moving a second end of the pressing board upward to pivot in a first direction. A second power unit has a second swaying frame pivoting from a first position to a second position to output second power, thereby moving the first end of the pressing board upward and moving the second end of the pressing board downward to pivot in a second direction. Upward movement of the first end causes the first swaying frame to pivot in the second direction to the first position. Downward movement of the second end causes the second swaying frame to pivot in the second direction to the first position.

The present disclosure provides approaches for reducing tobacco-specific nitrosamines (TSNAs) in tobacco. Some of these approaches include genetically engineering tobacco plants to increase one or more antioxidants, increase oxygen radicle absorbance capacity (ORAC), or reduce nitrite. Also provided are methods and compositions for producing modified tobacco plants and tobacco products therefrom comprising reduced TSNAs.

A photovoltaic renewable energy system utilizes a light source and one or more reflectors to produce power via photovoltaic cells. An exemplary photovoltaic renewable energy system utilizes a light source, such as Light Emitting Diodes (LED), to provide light to photovoltaic cells that therein produce electrical power. The photovoltaic cells may be arranged in a photovoltaic array to ensure maximum power conversion from the incident light. A reflector, such as a prism may be used to direct light from the light source onto the photovoltaic cells. A cell reflector, which may also be a prism, may be configured proximal to the photovoltaic cell surfaces to reflect light onto the photovoltaic surface to increase power conversion.

A green energy generating system (e.g., thermal, solar, wind, kinetic) is integrated with a selective molecular separation (i.e., greenhouse gas capturing) system. The output of each system is utilized by the other to form a unitary system that produces green energy (i.e., electricity) while separating/capturing predetermined molecules (e.g., greenhouse gases) from the environment. The process includes providing kinetic energy fluid from an energy source; driving a turbine via the kinetic energy fluid; driving a generator via the turbine to generate electricity; supplying (i) the kinetic energy fluid exiting the turbine and/or (ii) electricity generated by the generator to a molecular separation unit; intaking the predetermined molecules into the separation unit and selectively separating at least one predetermined molecule from other molecules; and capturing the predetermined molecule via a desorption process using heat from thermal energy of (i) the kinetic energy fluid and/or (ii) an electrical heater powered by the electricity.
