Just as wars over oil played a major role in 20th century history, there is a convincing case that many 21st century conflicts will be fought over water. World water use in the past century has grown twice as fast as world population. Right now, almost a billion people on the planet don’t have access to clean, safe drinking water. That’s one in eight of us!
Suddenly we're going to have to find a way to use the existing water resources in a far, far more productive manner than we ever did before, because there's simply not enough.
Waterpebble - The clever device monitors water going down the plug hole when you shower. Memorising your first shower and using it as a benchmark, Waterpebble then indicates, via a series of ‘traffic lights’ flashing gently from green through to red, when to finish showering.
Each time you shower Waterpebble automatically fractionally reduces your shower time helping you to save water without needing to think about it.
