Abstract
Portable power generating devices are provided for converting potential energy from flowing water, water current, blowing air or air current to mechanical and/or electrical energy. The potential energy is converted to a rotational movement, and the rotational energy is communicated to power conversion units for conversion, wherein the rotational movement is converted to mechanical, electrical or some other useable or useful energy.
