Instructables
ok so when submitting my water pump instructable i saw the competion for paper coffee cups, this gave me some ideas but the closing date is the 9th, today is the 9th (at 2.26am) so i dont have time to get hold of a bunch of paper coffee cups and i dont think it would be in the spirt of the thing just to get a load and waste them. so i have done some diagrams to demostrate my idea.

when i was in school back when i was 16 years old i was asked to design a wind mill for charging batterys, it was a spectacular failure, since then i have thought how it could be done much better. this challenge has bought me back to that idea.

Step 1: You will need

you will need

a bunch of paper coffee cups

a 26 inche steel bicycle wheel

some sheet steel

a steel rod

a large steel washer that will fit over the rod

and an alternator

you will also need some cutting tools and also a welder, a hot glue gun, and time

if you used a rear wheel you wouldn't need to modify the axel you could take the drive straight off the sprocket a fixed wheel for a track bike would be best but a free wheel mechanism drives one way

how much power does this generate?

The advantage of this configuration on a VAWT is that here you can put a windscreen on top. Well, now I realize that if one adds to the VAWT a tail with a windscreen, obtains the same result. It will Improve the performance, to avoid the wind affecting the "bad side" of the turbine. Pardon my English, say me if you don't understand.

how do you mean "windscreen"??
A windscreen is a screen or courtain that intercepts or redirects the wind. If you avoid the wind on the upper part of your turbine, it will functions more efficiently. You can redirect the upper wind toward the lower part, it will be better.

ok just so everyones aware i was basing this windmill on the same design as in the pic below, there could be improvements agreeded such as water proofing, which if you think about it you dont have to do too much as a car alternator does get wet even if it is under your bonnet.

anyway, as i said this is basically a mod of the idea in my head, which is what is pictured below, using coffee cups to fit the comp

Whilst I am fairly sure that this would work, I am also sure that it could work better.

Why not make it VAWT?  Do away with the fin and simply fix the wheel of cups directly to the alternator?  No losses from friction at the gears, no worries about wind direction.

i realised that today your right, but it was 5am when i did this so i was lagging a bit and prehaps not thinking as straight as i could have been, this one does look cool though
It does look cool.

In my head, I see it at the top of a tall, skeletal tower, like those windmills used in the mid-west to raise water for the fields.

yeah i totally get what your saying and it would be a hell of a lot easier , oh well it was just a thoery at least i didnt waste time making it to find it out lol
