Earlier on this year we went out to Africa to put in place two solar water pumps for a farm there.
Teaching to enable replication: We explained how they worked so that the people who would use them could install them. This was so that after we left they’d be able to modify them as needed, add more pumps, teach others how to use them and so spread the opportunities. And they should be able to get the materials because we could find solar panels for sale in the nearest town and pumps in the capital Lilongwe.
This was only a couple of months ago so we’ll update this with progress when we hear how things are going. In the meantime, here’s a video showing how we did it.
Please do write if you have any suggestions, comments or questions. Cheers!! Simon
