MEGA CYLCE OF WATER: Economic and Engineering Plan [Agave Book 2]

A new solar-powered desalination technology could help solve water shortage problems without any damage to the environment, according to researchers. They evaluated a prototype model and demonstrated that it could produce up to 12 litres of freshwater a day per m2 of equipment.

Desalination plants, powered by wind energy, offer the potential to produce freshwater using a renewable source of energy. A recent study has explored some of the challenges of integrating wind energy with desalination units, and suggests combining wind with other forms of renewable energy, or constructing a system that operates with variable energy input would help overcome problems with wind powered desalination.

Desalination technologies could help alleviate water shortages, but they need to have low environmental impact. A new life-cycle analysis of desalination options for water supply in off-grid areas indicates that a photovoltaic-powered reverse osmosis system has the least environmental impact of the three technologies considered by the study.

Santa Monica's iconic amusement pier is the site of this year's Land Art Generator Initiative. The Pipe is an offshore desalination concept that's making waves.

An award-winning MIT team has created a portable, solar-powered desalination system that could provide freshwater in remote locations.

Methods and systems are provided for air conditioning, capturing combustion contaminants, desalination, and other processes using liquid desiccants.

An evaporative desalination device includes a multi stage vapor generator that generates vapor by passing a hot water supply pipe successively through a plurality of vapor generators to evaporate sea water inside thereof, a multi effect vapor generator that uses vapor in the respective vapor generators as heat source and forms a plurality of evaporator groups which can adjust a number of evaporators disposed inside the respective evaporator groups and produce fresh water according to amounts of supplied vapor to evaporate sea water in the evaporator groups on an outer circumference surface of an evaporation tube by heat of vapor flowing in the evaporation tube, and a discharge unit that condenses vapor in the multi effect generator by sea water to discharge fresh water in liquid state, and returns and supplies portions of discharged sea water to the multi stage vapor generator and the multi effect evaporator.

Volunteer whale spotters believe they've photographed more than 50 whales at South Australia's Sleaford Bay this year, raising questions about how the marine mammals might be affected by a desalination plant proposed for the area.

Murray River water destined for Adelaide will be reallocated to farmers upstream so they can grow feed for their livestock, as part of a federal drought stimulus package announced today.

The UK government has approved a new scheme for desalination of water from the Thames, for use in London. The £200 million plant will be built in Beckton, east London. It's not a popular plan, though, among environmental campaigners. We've written before

We´ve noted in the past plans for new desalination plants in Australia and low-grade energy desalination technology from New Mexico.

Record droughts, falling water tables and the rapid depletion of aquifers have helped make desalination, a process once considered impractical and too expensive, a viable technology -- at least in some places. As such, there has been a rash of stories --

Directed by David Valero for the Spanish eco-short-films festival La Luciernaga fundida, this video shows how a grandmother and grandson desalinate seawater at home.

Using solar stills to purify water isn't a new idea, but it's an effective one. And now new efforts are underway to use this old technology to help green the desert.

A new desalination technology company is looking to help clean up and recover some of the trillion gallons of salty wastewater from the oil and gas industry.

A new water treatment system could save billions of gallons of water each year by recovering almost all of the waste water at bottling plants and water treatment facilities.

The UAE's clean tech giant plans to have a commerical-scale plant by 2020.

By combining solar PV, solar thermal, and a heat exchanger, Desolenator has developed a low-cost portable water purifier and desalination device powered by renewable energy.

This system could produce 3,500 gallons of clean water per day, at half the cost of current desalination methods, using just the motion of the waves to power the Reverse Osmosis process.
