Power generation devices and methods for use with toilets is disclosed. A number of power generation devices are provided that can be used in combination to power various features in a toilet which will be particularly useful for portable toilets that are off the grid. The power generation devices and methods include, for example, using a cell battery inside a toilet water source, a wind turbine, solar panels, and piezoelectricity. The features include, for example, lighting up the toilet with light-emitting diodes (LEDs) to make it easier for users to find the toilet, an audio/video setup for entertainment, and a toilet status light indicator to let the next user know when the toilet paper is out.

Provided is a wind power installation for converting the kinetic energy of the wind into the mechanical energy of rotation of a rotor for subsequent conversion of the mechanical energy of rotation into the electrical energy. A wind power installation includes a support frame, a shaft disposed on the support frame, and a blade system mounted on the shaft. The shaft is configured to rotate about a vertical axis and is functionally connected to an electric generator. The support frame is configured to be mounted between at least three radially arranged structures. The wind power installation can include additional blade systems disposed one above another on the shaft. Mounting the support frame between three radially arranged structures results in greater rigidity and robustness of the wind power installation, thus enabling the use of blade systems having a larger blade area and the arrangement of several blade systems on the shaft.

The electrical power generation system using renewable energy is particularly adapted to provide electrical power to an independent or remotely situated electrical device such as a street light, emergency call box, or illuminated road sign. The system includes a pivotally mounted venturi with vanes assuring that the venturi is oriented into the prevailing wind. A vertical axis wind turbine is installed in the venturi throat, and drives a shaft extending through the column upon which the venturi is installed to a generator at the base of the column. The venturi and vanes may include photovoltaic cells thereon for further electrical power. The venturi may be heated from a geothermal source, and may include a variable diameter internal wall to adjust the cross-sectional area of the throat of the venturi. The use of functionally graded materials and other phase change materials may also improve the performance of the device.
