What do you do with ample geothermal hotspots but frigid, windswept landscapes? Grow greenhouse tomatoes, of course. Knútur Rafn Ármann, co-founder of Friðheimar farm, cultivates tasty tomatoes by using nearby geothermal energy to light crops all year long—and with much success. Friðheimar's annual harvest exceeds 370 tons of tomatoes and cucumbers. Here, Ármann demonstrates how bees pollinate the plants.
