Very cool! Thanks for sharing! I live in AZ so it's extra relevant to me. Years ago I theorized that we could solve a lot of hunger in the world if we could somehow harvest the cacti on a large scale and get them to hungry people.. There's just cacti all over the place. if you know how to get the spines off, it's like free food everywhere where I live, and elsewhere in the world..
