Windbelt

great ingenuity....but real shitty music.

[midorifugu777]

fantastic !! you make it looks so easy!

interested to see and understand more. where is your homepage?

[sfaelectronics]

That is a motor/generator connected to a capacitor.

@5:20 how do you call that moving thing!?

[Danster82]

build one out of a bridge and connect the magnets to either-side of the road, that will generate some serious power :)

[morizio1]

i like this. can you put some write desciptions ?

[sfaelectronics]

Yes, I'll try to put some info online this month. More news later.

where can i get that kind of "tape" or belt... i dont know how to say

[sfaelectronics]

I found it at Wal-Mart in the fabric section. It was 3 inches wide so I had to cut it.

[lalitoGUM]

thanks men,,,, i tought it was some kind of special tape

[sfaelectronics]

Shawn Frayne, the inventor of the windbelt, calls it "mylar coated taffeta". What you are seeing in this video is just taffeta (fabric).

All the examples apprear to be a single ribbon. Has anyone built an array of these? Either a 2D array (a line up) or a 3D array (multiple line ups, in a grid). I'm interested to see how the wind might flow through and if the dynamics might regularize the voltages produced. The single belt model seems to have peaks and valleys in the voltage, which is a problem unless your on batterys.

yeah.. but just make your batteries so that they are between power source and appliance.. there is stuff like voltage stabalizer type thing etc

@angurisloud Nice idea, especially if you size the belts for the decreasing windspeed due to the previous ones absorbing energy from it. Voltage is sinusoidal-like, quite similar to usual AC if the coil is kept fixed and the wind blows regularly enough (at least as I can see from here)
