Consumers are about to get fresh cooking tips from, of all places, their refrigerator. South Korea's LG Electronics recently introduced a smart fridge that “suggests” healthy recipes based on the food that's inside. The appliance also detects when items go bad, and can relay a shopping list to the user's smartphone. With a price tag of $3,300, the new refrigerator is the latest addition to a growing line of tech-heavy appliances designed to make modern living easier. According to market research firm Pike Research, these intelligent fixtures tallied $40 million in sales last year and are expected to reach $6.2 billion by 2015.
