MemPower: Clear Water And Electricity from Ocean Water

MemPower, clean drinking water and electricity from ocean water

You can also use it for processes in industry such as the energy and chemical sector and the food and bio-based industry.

While there is plenty of water in the world, good-quality drinking water can be scarce. MemPower employs membrane distillation using solar or residual heat to produce very pure water.

This new technology does not need electricity but generates it instead, so clean drinking water and electricity are produced from saltwater at the same time.

Wageningen University & Research is looking for partners to further develop and market this promising innovation, which won the MBR Global Water Award in 2017.

17 year old kid developed cheap way to make salt water potable

17 year old kid develops cheap way to make salt water potable

Why does scientists focus that much at that ten percent if we deal with the 90 percent?

This kid is amazing. The 17-year-old Chai developed a logic technology to turn salt water into fresh water.

Over 70 percent of the earth’s surface is covered with water, but only a fraction of it is fresh water. Scientists know how to get the salt out of seawater, but have so far not found an affordable way to do that inexpensive on a large scale.

Chaitanya Karamchedu seens to have the solution.

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.

Drip irrigation’s compostable plastic pipes for sustainable agriculture

Israel’s turnaround came with a seven-year drought, one of the most severe to hit modern Israel, that began in 2005 and peaked in the winter of 2008 to 2009.

The country needed to introduce measures and become drought resistant.

Now, the country has enough water for people, industries and agri.

What did they do? Lessons learned from a country where every drop of water counts.

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

Desalination, fresh water, drinking water, sea water, reverse osmosis, climate change

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

Haiti gets clean drinking water

In addition, changes in weather patterns in the Caribbean due to climate change are exacerbating existing water challenges. 

Desalination is not new to the Caribbean, but extracting clean water from seawater is becoming an increasingly integral part of the region’s search for water security.

Since 2007, 68 new desalination plants have been built across the Caribbean, which now boasts an installed capacity of 782,000 cubic metres of purified water per day, according to the Caribbean Desalination Association.

Molten Salt Batteries are cheap, simple and havethe potential for an infinite life

The energy storage market is blossoming. Because we need renewable energy storage to supply our smart electrical grids at daily moments the demand for energy is high.

The Molten Salt Battery is a battery to watch right now. An overview. 

In Molten Salt Batteries (also known as liquid metal batteries) two liquid electrodes are separated by a molten salt electrolyte.

Characteristic of salts is that these are guiding in the liquid state because the ions are allowed to move freely. The salt and the electrodes separate themselves by their different densities and immiscibility. Read More

There might be a solutions for the future. A desalination plant which is cost efficient and delivers health, cheap drinking water

Desalination of Pacific Ocean water may prove to be a cheaper solution for California. California is running out of water. Since 2010 progressive drought is rendering the Central Valley, into a desert.

The San Joaquin and Sacramento Rivers are drying up as is the aquifer beneath them. The Colorado River basin no longer meets the freshwater demands of both landowners and city dwellers in the U.S. Southwest. Read More
