Wind pump for pond ?

Hi,

I'm about to install a small pond in my garden. I plan on planting a lot of plants in it and not have any fish. In theory that could be enough to keep the water clean for a bigger pond, but I'm not sure it's going to work in mine. It might get a bit hot in summer.
The solution would of course to use a pump.
I was wondering, does anybody know of a pump design that uses wind energy, the way big windmills are used in agriculture ? Of course I would need something small, my pond is only 1,20 x 0,8 meters.

Cheers.

I don't know the answer to your question about the pump, but just wanted to say we have a similar sized pond that gets full sun all summer. The first summer we had a bad algal bloom, which we treated with barley straw and water from a healthy pond. Since then (over ten years), the water has stayed clean and clear. If you can prime your pond with healthy micro-organisms with a few buckets of water from an established healthy pond, you may find you don't need a pump.
