("50 cents: How much more Backyard Farms' tasty tomatoes cost per pound than traditional ones. High-efficiency LED lighting may some- day help lower energy costs and thus prices")

My comment: This illustration is about hydroponics industry. My previous posting, about Four Season Farm of Maine, does not use lighting or heating in winter, the main culprits of losing money. Robotics will lose even more money, which consume energy, not to mention the upfront cost to install equipment.
