Tired of paying the exorbitant markup for fresh produce at your grocery store? For a mere $70,000—and the cost of finding someplace else to park your car—this compact hydroponics container lets you grow a farm's worth of vegetables on a minimal chunk of land.
In fact, the creators of the aqua-cube claim it can successfully grow up to 23 different varieties of leafy vegetables, or smaller root plants like radishes and turnips, at the same time. And while $70,000 is certainly a steep investment, its yield is promised to be upwards of 10,000 heads of lettuce per year. More than the average family can consume, but perfect for a restaurant with a free parking spot near the kitchen. Just make sure you spring for the rooftop solar panel option to help cut down on the aqua-cube's $4,500 yearly power bill.
