Where else is heedless! The length of the major canals of Pakistan is 60 thousand km and the canals are more than 1.6 million km long. Water continues to flow in these canals for irrigation, in which such small touchable hand turbines can be placed to generate electricity day and night. These manual turbines can also generate electricity from water moving at very slow speeds (up to 1 meter per second). They are environmentally friendly and can be kept in large numbers in the same canal or furrow. They are inexpensive and can be easily carried everywhere. It can also be produced locally. For now, see the video of the manual turbine made by the Canadian company, which we can also produce by reverse engineering.
