Mưa có thủm nhà không?
It's like Lincoln logs. A wierd toy before legos were invented. Presumably.
Have you looked into toroidal propellers for the DIY hydroelectric turbines?
Greetings. Thank you for your videos. You are a real engineer! Of all the turbines, which one do you think has the maximum power and maximum efficiency? Archimedes' screw? I have a slight height difference. The flow is 20 liters/second
