Plastic or PET bottles are a huge percentage of pollution, and we could easily curb a lot of that by simply employing reusable water bottles. The concept bottle by Fernd Van Engelen at Artefact is a reusable bottle with numeric dials on top to keep track of the number of bottles saved by the use of 999 bottles.
Each time users refill the bottle, they are expected to move the counter by 1 and keep a track of the number of bottles they saved. A companion smartphone app and website shows users the amount of good saving each bottle can do. For example, 15 bottles is a stack about as tall as a giraffe. At 147, the bottles you have not consumed have saved you $326 and 7 gallons of oil.
