Clean drinking water is in large Parts of the world almost. Up to 2.1 billion people have none, and climate change is exacerbating the Situation. These innovations could help.
Clean drinking water without electricity
In many Parts of the world, the Problem is not a lack of water, but that the available water is dirty. That is hardly surprising, when you consider that in developing and emerging countries, 80 percent of the waste water is not cleaned. Because the SunSpring will help Hybrid. In the shiny cylinder is a filter system that can turn a day more than 20,000 litres of polluted water into drinking water. What is perhaps even more important: The plant can almost be set up anywhere in the shortest time possible and put into operation, as long as there is a water source like a river or a fountain in the vicinity. Thanks to the built-in solar cells and the optional wind Turbine, the System needs no power and runs for 10 years without maintenance — ideal for remote areas without connection to the electricity network, or places that have been devastated by extreme weather phenomena or other natural disasters.
Fog drink
But there are also places where even dirty water is scarce, such as in the Atacama desert in Northern Chile or in Parts of the Atlas mountains in Morocco. One thing these places have in common: each lot of fog. But you can’t drink, unfortunately. Or is it? Fog collectors to make the seemingly impossible possible. When the humid clouds move through the dense networks of tiny water droplets on the fibers and then run slowly on the mesh work down in a water tank. The idea is not new, but various researchers are working to make the fog collectors in a more efficient and more durable.
Do not rinse
To obtain clean water is not everything. It is also important that it be used sparingly. A place where we spend a lot of water waste is the toilet. A single flush on a traditional American toilet, it can consume up to 26 liters of the precious water. At the same time, a third of the world’s population still has no access to a real toilet, which pollutes the environment massively, and at the same time great health risks. How can we get all the toilet, to consume without at the same time so incredibly much water? DieNano Membrane toilet might be the solution. The odorless, High-Tech-toilet uses no water and no external energy. Instead, she turns the excrement into purified water and ashes by the user-supplied ‘biomass’ is used as a source of energy for the cleaning process. As futuristic as this may sound, it is not a reverie. The Design by researchers at the Cranfield University has won the ‘Reinvent the Toilet’competition, the Bill & Melinda Gates Foundation, and functional prototypes are already being tested under real-world conditions.
Floating Vegetable Beds
About 97.2 percent of the water on our planet is salty, what makes it suitable for the cultivation of food unsuitable. This does not want to accept Leilah Clarke, a design student from theuniversity of Sussex. She has designed a type of floating greenhouse-buoy, which produces its own fresh water. The idea is pretty simple: The buoys float on the sea, and the sea to evaporate the water. The moisture rises in the glass bell, and when it hits the glass, it condenses the water runs to the walls of the bell and watering the plants that grow there. It is still a prototype, but farms such as these, the swimming off the coast of desert areas could provide food without consuming the scarce ground water to the Land.

The most precious ElementWater: The finite resource
About two-thirds of the earth is covered by water. Only a fraction – three percent – is fresh water. And of this already limited resource, more and more people to draw upon. Now, about two billion of them have no reliable access to drinking water.
-
The most precious ElementThe water is running out
A further two billion people live in areas suffering from water scarcity. Their number will increase in the coming years due to climate change. According to estimates, by 2050 three billion people in the neighborhoods will live with water scarcity.

The most precious ElementThe nature of use
To the United Nations for 25 years, every 22.March with the world water day the attention of. Every year, he is under a different Motto. This year, it is “Nature for Water”, i.e., solutions from nature for drought, Flooding, and pollution. For example, you could connect rivers to Floodplains, or wetlands to recover areas.

The most precious ElementWastewater as an alternative source
Another solution to waste water. Properly treated, it can be used again and again. This protects the environment and is efficient. Because instead of getting new water tap into sources that used a certain amount of water again. But the procedure is time-consuming and expensive. Only a few countries can afford the.

The most precious ElementWaste Of Resource Is Spent
Israel uses 90 percent of its wastewater, for example for agricultural irrigation. Most of the countries do not have the necessary infrastructure to use this resource. Worldwide, 80 percent of the waste water passes untreated to be back in nature and polluted the waters.
-
The most precious ElementLack of potable water
Well-treated wastewater could also help against another Problem: a lack of drinking water. Namibia and Singapore already use highly treated wastewater as drinking water. In many countries, but there are caveats. Too great was the fear of diseases, the water should be not been cleaned thoroughly enough.

The most precious ElementHazards in the bottle
People resort to bottled drinking water in bottles to drink instead of tap water. Pollutants there might be here. According to a recently published study bottles plastic residue might be from the packaging of the water are to be found in many mineral water.
