Waterpebble: Saving water one drop at a time
Waterpebble is a harmless and trendy Eco-gadget designed to help raise awareness regarding how much water is being used while in the shower, and to help decrease that amount so gradually that it’s practically undetectable. The goal is to make saving water fun and easy while bringing its importance to the forefront.
Inventor:
Paul Priestman is the innovative mind behind Waterpebble and was originally inspired by a hotel bathroom sign that read, “Please Use Water Sparingly(俭省地).”
Usage:
The Waterpebble is a small round device that has three light indications of red, orange and green. They indicate, respectively, “Too much”, “Just enough” and “Well done — you’re saving the planet” .Simply place Waterpebble in the bottom of the shower and it records the length of your showers. From that point on it starts gradually encouraging you to reduce your shower time by flashing the appropriate light. If you let it go all the way to red, then you have exceeded(超过)the amount of time of your shower. If you stop showering at green, you have kept your shower at six minutes or less and have beat your record.
Effects:
Families who use Waterpebble can look forward to low water fees on their future water bills. It is a clever and environmentally-friendly way to make the process of saving water more instinctive. Waterpebble is not only encouraging people to use less water, but also helping people to become educated about conservation. Families report that their kids love the idea of playing a role in protecting the planet and without being constantly reminded. Waterpebble is being praised as a constructive device that allows people to ease into water conservation in a way that is enjoyable and educational.
