Hydropower is a clean, renewable energy source, and while large hydroelectric plants require massive infrastructure, you can actually make a DIY water turbine at home with simple tools and recycled materials. This type of homemade hydropower generator is perfect for students, hobbyists, or anyone who wants to learn how renewable energy works in practice. In this guide, we’ll show you step by step how to build a small water turbine at home.

The working principle of impulse turbines is the same as that of reaction turbines in that they both use the force and reaction force principle of water flow and runner blades to transmit water flow energy to the runner, causing the runner to rotate and release mechanical energy. The main difference between impulse turbine and reaction turbine lies in the way water enters and exits the turbine, as well as the working principle of the water turbine.

Most modern water turbines are installed in hydroelectric power stations to drive generators to produce electricity. In a hydroelectric power plant, water from the upstream reservoir is led to the turbine through a diversion pipe, which pushes the turbine runner to rotate and drive the generator to produce electricity. The water that has completed its work is discharged downstream through the tailrace pipeline. The higher the water head and flow rate, the greater the output power of the water turbine.

Selection of water turbine is an important task in the design of hydropower plant, and whether this problem is solved correctly or not has an important influence on the investment, construction speed, power generation and the amount of expected output of the hydropower plant, as well as on the degree of utilization of water energy resources during the whole period of operation, and the economy and flexibility of the operation of the hydropower plant.
