"This computer will grow your food in the future" by Caleb Harper

As Caleb Harper tells it, fewer people are getting into the farming business each year, which could threaten global crop production. Harper, the director of MIT's Open Agriculture Initiative, developed a solution that may simplify the food production process.

Harper's food computer is a device that can monitor and regulate growing conditions for crops. It grows food indoors in tighly controlled environments, handling variables like humidity and mineral quantities automatically. The result is a near-perfect crop of vegetables on a small scale — think tiny beds of lettuce, broccoli, and tomatoes — and the potential for sustainability on a wide scale.
