Actually studying permaculture with Geoff Lawton, I met Jon Jandai a week ago and have a talk about your system for my permaculture project in Mae Chaem valley (behind Doi Inthanon) where we have a plot of land. This is a region where farmers heavily use pesticide and chemical fertilizer. We will need your technology to:
1. Use for our project to filter water
2. Show by the example and demonstration to locals who to use it, setup it and get the benefits
I just found a USD 100.
Hope we can have a talk, Xavier
