A Intermittent Wind Powered Generator (New Concept)

[agungk]

crazy flapping wind generator...

something else you could try (conceptually):

make an array of thin flexible blades, each with one end sitting on piezo crystal. rectify each piezo output befor combining in series or parallel or both.

position the array with some angle of attack with the nominal wind. when the wind blows, the blades should vibrate and you'll get electricity.

If you add a spring you might make it more efficient. Once the kite pulls the string out fully no more energy is being captured. With a spring you could store some extra energy that gives the magnet a stronger rebound when the wind slows.

One could provide some means of varying the counterweight based on average wind speed, in order to more accurately 'balance' the wind-catching device and the counterweight based on current wind conditions. This should make the system more efficient. Also, consider using a balloon-shape for the wind catcher.

Hi, I like the idea/concept. I noticed something watching it and wanted to suggest another version. I noticed that the kite likes to stay floating which causes the magnet to spend most of the time in a holding pattern either in or out. I also noticed stronger and tighter pulling force on the tube than the string. My thought, connect kite-tube-magnet like @---o firm, then place magnet end into coil. let me know if you want more info to try it, anyways nice project/video.

Hi Thanks for your comment.

Yes, this system is working intermittently. I think we can change the design of kite-like object, to make the kite much easy to un-balance in blowing wind.

The shape of the kite I am thinking, is like a big disc, with a wire in center. This kind of shape is very un-even. But I did not test it yet.
