MoS2 Nanopores Desalination

MoS2 Nanopores

Tiny holes called nanopores, is specially designed to let high volumes of water through but keep salt and other contaminates out

MoS2 Nanopores, developed by the University of Illinois, seems to be an energy-efficient technique for removing salt from seawater. The material, a nanometer-thick sheet of molybdenum disulfide (MoS2) riddled with tiny holes called nanopores, is specially designed to let high volumes of water through but keep salt and other contaminates out, a process called desalination.

WaterSeer produces water from air

WaterSeer produces water from air

WaterSeer can pull up to 11 gallons of water from thin air

WaterSeer is the name of the turbine that can produce water from air. The WaterSeer could generate up to 11 gallons a day.

VICI-Labs, together with UC Berkeley and the National Peace Corps Association, have developed a wind turbine that could produce clean water from thin air 24/7. Read More

Top 10 Eco Cities

Top 10 Eco Cities Eco cities have a huge opportunity to impact the magnitude of climate exchange: after all, larger cities are consuming two thirds of the world’s energy and responsible for emitting over 70% of global CO2 emissions.

We analyzed the key objectives of the top 10 eco cities that were ranked highest in terms of environmental sustainability. Read More

Green affortable desalination technology Virgin Islands, using gravitation

Since last weekend, the Virgin Islands, an archipelago in the Caribbean Sea, runs a sustainable desalination plant on solar power, designed by ‘Elemental Water Makers’.

Seawater is converted into fresh water with renewable energy sources. Read More

Matt Damon: Ambassador For Water

Matt Damon, World Economic Forum, Climate Change, Global issues, milieu activist, sustainable

Matt Damon has been speaking with world leaders at the World Economic Forum in Davos (early 2015)

Matt Damon  has chosen to tackle the ultimate global threat: clean drinking water. Global water sanitation is a huge problem but there are a lot of proven solutions for it.

On his travels in developing countries, he realized that practical solutions already existed. But they need more attention. That’s why he started Water.org in 2009.

Worlds largest desalination plant Ras Alkhair, Saoudi Arabia

This largest clean water plant in Ras Alkhair in Saudi Arabia, is based on reverse osmosis desalination.

The installation has started since 2014 and is supplying 1 million cubic meters of drinking water every day. It uses 2400 MW of power for the desalination processes.

The installation has been built hybrid with 8 evaporators and17 reverse osmosis units. Read More

Costs of sea water desalination are going down

With Memstill, it is possible to desalinate a cubic meter of drinking water for 0.50 Euro cents from seawater.

Less water is always the best option.

But in case of a shortage of fresh water, nowadays the preparation of drinking water from seawater is a great alternative.

And the costs of sea water desalination are going down.

Thermal desalination has been overtaken by reverse osmosis and that led to some major changes:

  • the proces is much cheaper
  • the energy consumption during the proces has decreased sharply

Green, Blue Cities are Climate Proof

Worldwide, urban areas have to deal with climate change.  Consequences:  to much water, drought and not enough drinking water. It’s time for climate change adaptation. More water and flora (making the city greener) will make the city more resilient during periods of extreme rainfall or drought. Read More

Tokyo nr. 1, water stressed cities of the world

Want to know which cities suffer from water stress? The Nature Conservancy has published a list of the top 20 of cities with water stress.

Over 500 cities around the world were investigated. In (big) cities like Tokyo, Shanghai and LA, a large number of people in a relatively small area puts a lot of pressure on water supplies, especially during times of drought.  Read More

Water purification with Solar Power

Purification, solar power, fresh water tech, climate change

Solar energy purifies water

Purification – or the treatment of salt and/or – dirty water into drinking water exists in many countries. New solutions must be sought in small scale and local applicable technologies.

A well-known technique is electricity from solar panels, which only need the sun as an energy source.  Read More
