In this video, I test my fully homemade 220V mini hydropower dam — built from concrete, a custom water channel, and a compact turbine system.
You’ll see the raw power of this small stream as it drives the generator strong enough to light up multiple bulbs and even boil water with an electric kettle.
Watch the full process:
💧 The water flow design and mini-dam structure
⚙️ Turbine setup hidden inside the water chamber
⚡ Real 220V output powering household devices
🔌 Load tests with light bulbs and a kettle
🏗 Behind-the-scenes look at the concrete construction
This build is perfect for anyone interested in:
• Off-grid electricity
• Mini hydropower systems
• DIY engineering
• Renewable energy
