We have heard a lot about a building with greeneries on the rooftop. However, a bus? I find it something new. The bus Roots, designed by Marco Castro Cosio is a one of a kind bus that will surely catch every traveler’s eyes the moment it pass in front of them. I find this idea an eco-friendly one. Instead of installing those costly insulation tool. It will not only keep the bus interior cool and refreshing, it can also help save on the bus’ energy uses as plants help insulates. You probably will have the choice as to what you were going to plant in your bus top. Maybe you can have vegetables, flowers, and the like.
