Here is a link to a gentleman who rigged it up to an exercise bike for faster production. He's getting about half a liter every 15 minutes! Of particular interest is his modified nozzle/cap. The original nozzle is just a standard iron pipe reducer, which can cause problems because the waste shells that come out harden something akin to concrete the moment you stop cranking. Because the pipe reducer has internal threads, the ground hulls actually lock into the threads and solidify inside the nozzle. Many folks need to soak the nozzle in water for a day just to unplug it. This gentleman has had a custom tapered nozzle machined out of stainless steel, that is completely smooth inside. To get that rock hard sunflower waste out he just gives it a good wack with a bolt and it pops right out!
