Two years ago, then MIT graduate student Caleb Harper built a fully networked farm of tomatoes, lettuce, and broccoli inside a fourth-floor lounge at the school's famed Media Lab. He hoped to prove he could use data science to optimize crop yields, boost nutrient density, and trim water consumption by 98 percent compared with traditional dirt farming, all of which he did. But there was no meaningful way to share his data with the world. Despite an ongoing boom in agricultural technology, no one cared about his findings or dared to share theirs. This September, he launched the Open Agriculture Initiative, the first open-source platform for global agriculture and food hackers.
