We are working on a micro hydropower plant. In the first weeks we were focusing on making the foundations for the penstock (a tube where the water runs through). But that´s not as easy as it looks like. Here you really realize where your materials are coming from. For example the sand needs to be digged out the river and than transported with donkeys. It takes so much more effort than just ordering materials. And even if we buy materials and transport it with a truck, we still need to bring it all the way up to the farm.
