I don't know. I was referring to this part of the article by the way: "They can be as small as a thick iPad," says MacFarlane, "and that could make a small amount of ammonia continuously to run a commercial greenhouse or hydroponics setup, for example." It is certainly positive that they can miniaturize their device that much. It still requires nitrogen to run. They would either need to deliver nitrogen supply or need to produce it locally in which case they would need to separate it from air which requires an additional device and process. https://en.wikipedia.org/wiki/Air_separation https://en.wikipedia.org/wiki/Air_separation
