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.

Trending: Sustainable Wastewater Reuse

Trending: Hydrovolta Sustainable Wastewater recycling system

Hydrovolta water recycling system

This trending wastewater reuse technology can reduce your water costs up to 95%.

It’s green, it is trending

The plug and play units will remove ions from industrial waste water by using the power of electricity (electrodialysis technology) and ultrasound as pre-treatment, with low pressure and energy, without using chemicals or high pressure osmosis.

It is supported by automatic regeneration of ions and self-cleaning filters and included with online water quality monitoring and telemetric control system.

Vacuum airlift for clean water

vacuum bio-cleaning

New Concept for Wastewater Treatment and Reuse

Coldep (France) developed this promising vacuum airlift technology which can move large volumes of water with a very low energy consumption. The only limitation of the system is its ability to lift water, with a maximum of fifty centimeters. And it’s all bio-cleaning. Read More

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.

PH2OG water from the air

PH2OG water from the air

water harvesting from Fog

PH2OG builds equipment that captures airborne water droplets from clouds and fog. The process requires no additional energy input and avoids both groundwater depletion and pollution, issues affecting both the development en developing world but directly contributed to by major bottled water companies.

In areas without access to surface or groundwater sources but with high incidence of low lying clouds or fog (generally elevated regions), fog harvesting has proven to be an inexpensive alternative.

Suriname can earn billions on clean water

Suriname fresh water opportunities 350

The south of Suriname has a lot of fresh water. This region, with a few traditional living communities, is an area of natural beauty.

Suriname in South America, is almost bankrupt. President Bouterse has to cut on salaries and other government spendings.

What could help the Suriname economy? Water. Suriname can earn billions on clean water.  Read More

Flexible Flood Barrier

flood barrier

This multi functional flood barrier offers the ability to change the height of the flood barrier.

This is a great low cost, green and rapid solution for a new river barrier. 

The UK suffered from floods in 2014. Neptune has an answer to it.

This barrier does not have to be knocked down and rebuilt. Its height can easily be increased on site responding to any unexpected increase in sea levels whenever they might occur. Read More

Underground water buffer resolves freshwater deficit Agriculture

The underground water buffer creates a robust freshwater supply, without expensive reversed osmosis

Climate change must take into Northern parts of the world with wetter winters and drier summers. That means less fresh water in the period when farmers there are most in need.

Underground water buffers will help the farmers. Since the summer 2015, a new underground water storage technique has been tested successfully. Read More

Concentrated Solar Power Pros & Cons

Concentrated Solar Power, Renewables, Carbon, Fresh Water, Climate change

Dish-engine concentrated solar power in Australia

Concentrated solar power (CSP) systems generate solar power by using mirrors or lenses to concentrate a large area of sunlight, or solar thermal energy, onto a small area.

Electricity is generated when the concentrated light is converted to heat, which drives a heat engine (usually a steam turbine) connected to an electrical power generator or powers a thermochemical reaction. Read More

Yemen: Two thirds of people no access to fresh water

A girl is drinking unsafe water

Clean drinking water is a growing problem in the war-torn Yemen.

Due to the ongoing bombardments and fighting, again millions of people have been cut from the basic needs of fresh water.

Oxfam warns: “They are forced to drink unsafe water, causing the outbreak of various diseases.”

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.

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

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

65% of China is running out of water

Climate change, clean water, drinking water, China, groundwater

China is one of the world’s largest water-using nations and is considered by the UN as one of the 13 countries with serious shortage of water.

China is running out of water. People in cities like Shanghai already search for water by drilling for groundwater themselves.

Throughout the city you see water hoses hanging at private houses providing groundwater because the supply of water from the tap is already for months heavily rationed by the government.

Already, water is scarce for two-thirds of China’s 660 cities and as China’s economy expands, so will its demand for water. Read More
