Showers are one of the top contributors to water usage, and waste, in the household. The makers of the Eva Bluetooth-connected shower head claim it can help you cut that water consumption in half by making sure water only pours down when you actually need it. A free companion app also tracks your water usage, compares it with other users and motivates you to keep saving in the long run, aiming to have the device pay for itself in just one year.

Drinking more water associated with numerous dietary benefits, study finds
For people who want to control their weight or reduce their intakes of sugar, sodium and saturated fat, tap water may be what the doctor ordered.
A new study that examined the dietary habits of more than 18,300 U.S. adults found the majority of people who increased their consumption of plain water — tap water or from a cooler, drinking fountain or bottle — by 1 percent reduced their total daily calorie intake as well as their consumption of saturated fat, sugar, sodium and cholesterol.

Clean energy from water
Fuel cells generate electrical energy through a chemical reaction of hydrogen and oxygen. To obtain clean energy, the splitting of water into its components of hydrogen and oxygen is critical. Researchers at the University of Basel study how sunlight can be used for this purpose. The scientific journal Chemical Communications published their latest results.
Is Asia’s water supply in trouble?
Based on a series of simulations ran through sophisticated computer models, researchers from MIT are highlighting the possibility that a significant percentage of the population of Asia could suffer severe water shortages by the year 2050. As a basis for the study, the team made use of a pre-existing MIT-generated computer model designed to simulate Asia’s complex economic, climate, and growth characteristics. A detailed water-use model known as a Water Resource System was then introduced, and the team ran a number of simulations aiming to cover the widest range of potential scenarios.
Each of the simulations tested the key variables by holding steady one or more of the factors while allowing another, such as population growth, to increase in line with predicted numbers. Each of the scenarios also accounted for, amongst a host of other factors, the interconnected nature of the water supply in the affected regions. For example, if climate change or any other contributing element causes the water basin at the top of a network to go unfilled, other basins further down the network that would ordinarily be fed by the primary basin suffer in kind.
