Next problem to solve in Wind Fan is the flow of the wind is not equal, so we cannot get steady electricity at all time. As I told earlier, that is a simple problem.
Calculate how much energy is needed for pumping the equal water (or if needed some more) that goes down to the generator (Bottom of the mountain), simultaneously to the upper tank of the mountain (Intake tank of the Penstock pipe)
Calculate how many small generators are needed for the generation of this much energy. Now calculate how much water has to be lifted up to 75 meter high tank for these generators to work one full day. Create one tank or several tanks. BUT WHEN CREATING TANKS CREATE TANK (OR TANKS) WHICH COULD AT A TIME STORE WATER FOR 30 DAYS. If creating that much big tanks on pillar is very difficult, create the tanks on the ground. That is base of the tank on the ground level of the mountain top and build it up.
Now you may be thinking, then how the water will fall on the small generator turbine. That is easy. On one side of the mountain, remove sand may in a measurement of 25-meter wide, 30-meter length and 100 meter depth. Create a tank there at that level may be 10-meter depth. On the top of the tank put strong concrete beams. On these concrete beams establish small generators that we talked before. But establish extra two generators for pumping water to wind fan base tanks. These base tanks are necessary in this case. If we transmit the power of wind fans through piston shafts then we will lose lot of power. But create wind fan base tanks and make the pistons to pump the water to main tank, which would contain water for thirty days. WHY THAT MUCH WATER? BECAUSE WITHIN 30 DAYS ANY WAY THERE WILL BE WIND.
Now another problem is when the level of the water tank goes down the speed of the generators will come down. That can be used by wind energy regulatory tanks. That is a tank small in size created each tank for each generator. We may not even need a tank for this. PVC tanks that will contain 2000 litter water will be enough. Now from the Main 30 day storage tank, make the necessary water connection to PVC tank. This PVC tank will be Just below the storage level of 30 day tank. Now how will we control the over flow of this PVC tank. Use Toilet Flush balls (The air balls which we use in the toilet flushes to stop water once the flesh tank is full). Use that system also. So the variation in the level of the falling energy would be that of three to four inches. We can adjust the movement of the flush balls by reducing its handle length.
All that problems are solved. Now I think there is only one more major problem. That is named as 123 sucking problem. It is named as 123 sucking problem, because we will have to use pipes which will have to be counted as 1, 2, 3, .. What is the need of this? This will be needed to avoid the big water swirl when the water goes in high speed to down, through Penstock pipe. So this system is used in penstock intake tank. (123 sucker pipe image is given below) after that old links)
