The fog harvest can give water for the most arid cities

Dumping water caught – a large-scale – can be provided with drinking water from the world’s largest cities.

In Chile, researchers came out after learning the potential of the fog in the desert of Alto Hospicio in the northern country.

The average rain in the region is less than 0.19 or (5 mm) per year.

“There are many social problems in the city,” he said, Universidad Mayor Virginia Carter Gamberini. “Poverty, drugs, many slums.”

With no access to water supply networks, people in the slums are relied on drinking water delivered by truck.

At the same time, the Sis clouds, which regularly gather on the mountain city, are an unused source, researchers say.

It is very simple to capture the fog water – a mesh hung between the poles and moistened clouds, when this subtle mesh passes through the drop form. Then water is directed to pipes and storage tanks.

This has been used in a small scale in the village south and in Central America in several decades – in places where the right fog conditions. One of the largest fog water collection systems In Morocco, on the edge of the Sahara desert.

However, Dr. Carter said that the larger-scale fog bar can provide more reliable and sustainable water supply in urban environments in the most needed urban environments.

The colleagues and colleagues and colleagues and counterparts combined how much water will be produced and the information about the clouds with satellite images and weather forecasts.

It was regularly able to provide the people of Clouds and Sahil Mountain, Alto Hospicio, a sustainable source of drinking water. They published their findings A paper in the boundaries of the environmental science.

Alto Hospicio’s foggy fogs occur on the Pacific – the hot, moist air flows over cold water – and then blown over the mountains. In the reliable foggy conditions here, Dr. Carter and colleagues allowed the largest volume of water to set the clouds to the areas where the water can be collected regularly.

Researchers worked on a square meter per day on a period of average water collection rate:

• 17,000 sq m mesh may provide enough water to meet a weekly water demand for a truck with a truck to the city slums
• 110 kv m can meet the annual demand for irrigation of the city’s green spaces
• Fog juice can be used for the landless (hydroponic) agriculture, with 33 to 44 (15 to 20 kg) in one month

Alto Hospcio is on the edge of the Atacama desert – one of the most dry places on earth. The main source of water sources of cities in the region until little rain – are the rock layers of water – these are the rock layers – these thousands of years ago were filled.

The city’s population is growing and the demand and scientists of the mineral supply and scientists are urgent need for other sustainable water sources.

Dr. Gamberini, Chile is “very special” for the sea fog, “We have the ocean throughout the country,” he said.

His team is currently working on the entire country’s fog product map.

“Water from the clouds”, as Dr. Carter described it, “he needs disbelief in reluctance of our cities to clean water,” he said.
