Summer is the season of not only holidays, but also repair. For many people it begins in the clouds of construction dust, and a cheerful singing grinder or punch. To make a candy form their homes, it will take time, money, nerves of steel and …much water. It is necessary for the preparation of solutions, washing tools, final cleaning. And those who paints, glues and plasterers have to wash more often than usual.
The exact calculation. It is unlikely that you thought about it before, but to save water without sacrificing quality in the process of repair is quite real. Building materials, cement, glue for wallpaper – of course, all this can’t be prepared without water. However, the generous gestures and working by eye are misplaced here, otherwise you’ll have to throw away the remaining solution. The mixture should be used as soon as possible, so never prepare it in advance and make new portions of solutions as far as you need them. Read more
Water is used around the world for the production of electricity, but new research results show that there will not be enough water in the world to meet demand by 2040 if the energy and power situation does not improve before then.
Two new reports that focus on the global electricity water nexus have just been published. Three years of research show that by the year 2040 there will not be enough water in the world to quench the thirst of the world population and keep the current energy and power solutions going if we continue doing what we are doing today. It is a clash of competing necessities, between drinking water and energy demand. Behind the research is a group of researchers from Aarhus University in Denmark, Vermont Law School and CNA Corporation in the US. Read more
An immensely powerful yet invisible force pulls water from Earth to the top of the tallest redwood and delivers snow to the tops of the Himalayas. Yet despite the power of evaporating water, its potential to propel self-sufficient devices or produce electricity has remained largely untapped — until now.
Eva, the first evaporation-powered car, has a turbine engine that rotates as water evaporates from the wet paper lining the walls of the engine.
In the June 16 online issue of Nature Communications, Columbia University scientists report the development of two novel devices that derive power directly from evaporation — a floating, piston-driven engine that generates electricity causing a light to flash, and a rotary engine that drives a miniature car.

The water flea has genetically adapted to climate change. Biologists from KU Leuven, Belgium, compared ‘resurrected’ water fleas — hatched from 40-year-old eggs — with more recent specimens. The project was coordinated by Professor Luc De Meester from the Laboratory of Aquatic Ecology, Evolution and Conservation.

884 million people around the world are without access to safe drinking water. And 2.6 billion are without adequate sanitation.
That’s why CDM Smith and our employees support Water For People, an international humanitarian organization of dedicated people who recognize water as a primary building block of life. Since 1991, Water For People has helped educate, guide, and connect people with the necessary human and financial resources to establish sustainable water systems. Read more
