Finally I took some time to see an interesting presentation on Google Tech Talks.
Shawn Frayne, a 28 year old inventor based in Mountain View talks about his wind belt, a new type of wind generator. The technology is suitable for the developing countries since is based on inexpensive patents, materials and manufacturing… The wind generator would cost around 5 dollars.
The wind generator is very symple. The wind passes over the Windbelt’s membrane, and the vibrations picks up (think leaf whistle) jiggle magnets on either end of the manbrane. The magnets, oscillating between metal coils, generate a current and a substantial current!!!
Believe it or not , he says:
Prototypes have generated 40 milliwatts in 10-mph slivers of wind, making his device 10 to 30 times as efficient as the best microturbines.
Frayne hopes that his invention will be put to use in developing countries , where there is currently an over-reliance on kerosene for light. As you can see in Popular Mechanics’ video, LEDs connected to the Windbelt light up easily in a gentle breeze.
I am fascinated by the idea that sometime very simple ideas can radically change the way of thinking. We all were used to associate wind energy to wind turbine but now we could produce energy in an even easier way and it incredibly works!! :O wow
The guy also says a remarkable insight. ( at 36:00 min of the you tube video):
The revolutionary inventions of the next 50-100 year will happen in the developing country because basic technologies need to be revolutionized for the new very sever constraints that they have. New constraints => New solutions!!
This is the video
