An Australian company called 'Half a Teaspoon' is dedicated to creating and introducing new products to to their market that would make it easier for consumers to make more environmental choices. Their latest product is the 321 Water Bottle that can instantly purify tap water with a plunger built into a portable bottle. Their website claims that one push will remove 'any chlorine, unpleasant tastes, and odors' from the water.
While the product design is interesting and the concept is commendable, I do not see this product surviving outside an urban environment. Firstly you would require access to fairly well treated tap water, and secondly it is just not as convenient as throwing a carton of bottled water into your car when you are heading out onto the road. Plastic waste is an issue we must contend with but new concepts must consider the function of the plastic bottle. Not only do plastic containers allow us to drink good quality water on demand, but also allow us to transport large quantities of drink water to locations where none is available.
