I'd love to see more innovation in farming practices. I'm a huge fan of aquaponics. Uses around 10% of the water of current farming techniques. I've got my own setup in my backyard. Right now I'm working on getting it started, but I'm planning on experimenting with growing wheat, and if I ever get a large enough system, I want to try growing trees, like almonds, which are traditionally pretty water intensive. These aren't generally worth growing at a small scale, but I figure if it can be done then maybe it could scale up. I really want to try making a combine harvester for wheat that runs on rails along the aquaponics grow beds to help in the automation.
