Designer David Veldkamp created this futuristic concept PC he calls the LawnPC. The device would create all the power it needs from solar cells embedded in the grass that sits on top of the PC. The grass isn’t real grass, it’s actually made from natural cotton fabric that carries inkjet printed solar cells. The use of cotton makes the blades biodegradable, just like real grass. The idea is that hundreds of these blades can generate all the power the system needs at about 60 Watts per hour. The blades transfer energy to the battery plug-in at the bottom of each blade. The Lawn PC is also completely wireless.
All the electricity is generated by the machine. Which doesn’t even require a cooling fan. The natural air flow in between the lawn is enough to cool the system. All you have to worry about is placing the system near a window or a vent, where it can get all the light and air it needs. The lawn is removable, so it will also power your other electronic devices. Those devices will look like they do now, just with a blade of grass sticking out of them like an organic antenna.
