The document discusses using a turbo ventilator to generate electrical energy from wind power. It begins with an introduction to conventional and non-conventional energy sources, focusing on wind and solar energy. It then describes how a turbo ventilator works, using the rotation from wind to power a generator. Test results showed the turbo ventilator producing voltages of 15V, 12V and 9V at speeds of 350rpm, 300rpm and 200rpm, respectively. In conclusion, the turbo ventilator provides a low-cost way to harness wind energy for small-scale power generation and ventilation.
