pico wind generator

[gcp1975]

here is my pico wind generator made from an old pc fan

sorry about the piccys will take more when i get reaquainted to MY shed

close up of coil , fitted to plastic from an old plastic blind.jpg

1st prototype - made of A4 card.jpg

i made this just to see if it would work ( lasted 2-3 mins but then fell apart !)

spay can hub with plastic milk bottle blades (note i got the pitch the wrong way).jpg

extra epoxy ( as wind destroyed original ) back to the drawing board !.jpg

finished prototype with an L.E.D attatched (just to test).jpg

shown without hub and blades

pics include a simple nail in the end of a piece of wood mast, and showing an L.E.D to prove that it worked..

i then added rectification and found that i can charge a poundland 1.2v rechargeable cell !! i know its not a lot but hopefully this project will get bigger !!!

looks good do you know how much power you get from it hang on I should ask how long does it take to charge a car battery, as soon as you start on amps I'm lost

Hmmm, I've got about 20 120mm pc fans in the cupboard...

junmist - you won't charge a car battery with it

I originally wanted to just charge aa/aaa batteries with it . a bit like a wind version of a solar freeloader !!

24942895 - google pico wind generators and do what i did !!!!

The amount of power obtained isn't useless.

You know those little spinny-round things on the top of vans, I think they are there to trickle charge the battery for all the stop-starts they do. Correct me if I'm wrong. And I can't imagine those little things kick out that much.

Probably charge a mobile phone too, with the right circuit.

it's a shame about the design of fan because, if you could have the shaft spinning though several you would get a bit more out.

Sorry about the dots, this text editor removes the spaces when you do this.

How interesting! Thanks for taking the time to post these

I'm wondering about that card one, the first one - if you did it with sheets of plastic, the sort of thing you get stationery folders made from, I wonder if that would be sufficient to do the same trickle thing? It looks like an easier design, I *think*.

Will google pico wind generators
