Wind Mills
Wind Mills
(OP)
I know that this isn't the correct thread - but you all are the ones I know best; the geotechs!!!! So, I'll ask anyway for I prefer to stay with those that are good colleagues.
I've a friend in Laos - a very poor country - who has been hitting me up for a small wind-mill design. You know, the ones you see on all the mid-west farms for horse troughs. It needs to be one that the locals can build. The reason is that even though the temps are moderate, they have no way of pumping water from always flowing rivers and creeks up to the areas for irrigation as they have no electricity to speak of. They also don't have any money to buy a ready made one either. I thought that the old farm wind mills - simple ones - might be enough to put water up for irrigation of land.
If anyone knows, please advise: bohica@rediffmail.com
Forgive me for putting this on our threads. Many thanks to all.

RE: Wind Mills
Basically the axis that takes the helix must pass its horizontal rotation to a chain that elevates the vessels with water, to be dumped by some kind of stop at the proper point.
Making it able to follow the wind may be an inconvenient complication.

good luck.

I hope it is of some help!
RE: Wind Mills
I don't know what the wind conditions are like, but if there's one or more days of no wind, the windmill will do nothing. In the meantime, so long as there's water in the river, it will continue to pump. Then, there's the possibility of damage to the windmill from monsoons and other tropical storms.

RE: Wind Mills
Being from the land of wind (Nebraska) I suggest that using the base materials available there would be of benefit.
Things I would like to ask are do they require electricity?
Is this Windmill being used just for irragation?
Is the farm or area of concern, in at least a class 3 wind site?
These are the base question I ask of anyone who wishes to built a windmill. Check out the area in Pipestone Minnesota. There are farmers that used a brace pole with a jacob turbine an ran thier farms from that and a battery bank.
Just some thoughts.
