This may sounds like something from science fiction novels, but a group from the UK are raising money on kickstarter to use a solar powered 3D printer to turn plastics collected at sea into furniture. The team will travel to the North Atlantic Gyre, where tons and tons of plastic trash resides. They will then turn that plastic into filament for a solar powered 3D printer which they built themselves. More details on this very interesting, and honorable project can be found here: http://3dprint.com/16222/3d-solar-print-garbage-sea/

Here is a picture of the solar powered 3D printer that the team will be using:
