So our solar-powered borehole in Cameroon is now live and working and providing clean drinking water at zero effort to hundreds of people. Yay! There are more details about the borehole here, here and also here. I might not have mentioned it before, but the cost is just over £20k. Very worthwhile when you think about how many people it will affect and the changes and improvements it enables. Anyway, they sent a very nice video celebrating the opening of the borehole, and here it is :D.
