Modular Hydroelectric Generator

A Modular River Electric Generator was created for rural areas in third world countries to provide affordable electricity for powering devices. Lack of electricity is a significant humanitarian issue that hinders economies and reduces quality of life. The generator, shaped like a plane, is placed underwater in rivers or streams. One device generates 30 watts of continuous energy, and villagers can attach multiple units to meet their energy needs. The generator is anchored by a rope spanning the river and secured to trees on both sides. An attached battery box stores excess electricity for later use. To reach remote communities, the design enables long-distance energy transfer. The generator is injection molded from ABS plastic for low-cost mass production, while 3D printing was used during prototyping. The underwater placement minimizes damage risks from floating debris. The aerodynamic design reduces drag and spinning forces. Watertight seals protect the generator from corrosion. A Kaplan turbine converts linear river energy into rotational energy, which is then converted to electrical energy by a stepper motor. A bridge rectifier changes the voltage to direct current for battery charging, while a variable resistor controls torque based on Ohm's law. A zener diode maintains optimal charging voltage, and an overcharge protector circuit prevents battery damage. The stored energy powers homes, medical centers, and businesses through a DC-to-AC car inverter, bringing light to impoverished regions.
