Designer David Velkamp came up with this clever and eco-friendly computer concept called the LawnPC. Its design features natural cotton grass-like "blades" that are covered in printed solar cells. These solar cells provide about 60 watts per hour to the computer. The miniature lawn sits on top of the computer. Best of all, the solar cell blades are all biodegradable.
