The countermeasure against the inundation This mechanism also becomes inundation countermeasure mechanism. When heavy rain is forecast, the water source is emptied, and when a river is likely to overflow, the amount of water of a river is taken in. @HOME @ ...

The potential energy "A" and "B" are the same potential energy, and "B" is equivalent to the flow of a river, etc. It is the theory in which "energy of B may be large because a speed comes out and the distance is long" is mistaken. If the mechanism which absorbs potential energy is made from "A", me...

Water-power generation Although it is main that a level difference is not less than 100m as for the dam of water-power generation, and if that level difference is low, a production of electricity will decrease, and it becomes uneconomical. The place where an efficient dam can be built is limited. If...

The advantage of the large flow If it is the large flow, large electric powers will be obtained. If the conversion of the large flow is easy, the power plant is economical, and it is because the cost of power generation is the price proportional to the production of electricity. This mechanism can c...

Non leak turbine If efficiency is not reduced by the low-speed big flow, energy can be efficiently taken out with the low water level difference. In a water wheel, however it may do, it is limited. But it will become possible if there is the air turbine of non leak. And if a rotor is lightweight and...
