Mashine ya Kutengeneza maji yagunduliwa

Israeli company Water-Gen has developed a device for extracting drinking water from air. It's already being used by the military, but Water-Gen says its future is in civilian uses.
Water. A vital nutrient, yet one that is inaccessible to many worldwide.
The World Health Organization reports that 780 million people don't have access to clean water, and 3.4 million die each year due to water-borne diseases. But an Israeli company thinks it can play a part in alleviating the crisis by producing drinking water from thin air.
Water-Gen has developed an Atmospheric Water-Generation Units using its "GENius" heat exchanger to chill air and condense water vapor.
"The clean air enters our GENius heat exchanger system where it is dehumidified, the water is removed from the air and collected in a collection tank inside the unit," says co-CEO Arye Kohavi.

"From there the water is passed through an extensive water filtration system which cleans it from possible chemical and microbiological contaminations," he explains. "The clean purified water is stored in an internal water tank which is kept continuously preserved to keep it at high quality over time."

Energy efficient
Capturing atmospheric humidity isn't a ground-breaking invention in itself -- other companies already sell atmospheric water generators for commercial and domestic use -- but Water-Gen says it has made its water generator more energy efficient than others by using the cooled air created by the unit to chill incoming air.

"Several companies tried to extract water from the air," says Kohavi. "It looks simple, because air conditioning is extracting water from air. But the issue is to do it very efficiently, to produce as much water as you can per kilowatt of power consumed."
He adds: "When you're very, very efficient, it brings us to the point that it is a real solution. Water from air became actually a solution for drinking water."

The system produces 250-800 liters (65-210 gallons) of potable water a day depending on temperature and humidity conditions and Kohavi says it uses two cents' worth of electricity to produce a liter of water.

Civilian uses
Developed primarily for the Israel Defense Forces (IDF), Water-Gen says it has already sold units to militaries in seven countries, but Kohavi is keen to stress that the general population can also benefit from the technology.

He explains: "We believe that the products can be sold to developing countries in different civilian applications. For example in India, [drinking] water for homes is not available and will also be rare in the future. The Atmospheric Water-Generation Unit can be built as a residential unit and serve as a perfect water supply solution for homes in India."
Kohavi says Water-Gen's units can produce a liter of water for 1.5 Rupees, as opposed to 15 Rupees for a liter of bottled water.

Dirty water
Another product Water-Gen has developed is a portable water purification system. It's a battery-operated water filtration unit called Spring. Spring is able to filter 180 liters (48 gallons) of water, and fits into a backpack -- enabling water filtration on the go.

"You can go to any lake, any place, any river, anything in the field, usually contaminated with industrial waste, or anything like that and actually filter it into the best drinking water that exists," says Kohavi.

"This unit gives logistic independence for the forces and make us ensure that we provide the soldiers high quality water," she says.
In 2013, the IDF took Spring to the Philippines after Typhoon Haiyan devastated the island country and left 4.2 million people affected by water scarcity. The system filtered what was undrinkable water into potable water, and that is what Water-Gen hopes to accomplish elsewhere where the technology is needed.

"It's something as a Westerner you cannot understand because you have a perfect water in the pipe, but people are dying from lack of water," says Kohavi.

Although Water-Gen's developments aren't a solution for the water crisis, Kohavi believes that the technology can do for countries that lack clean water, such as Haiti, what it has done for the Philippines. It can be the technology used to not only to filter water, but to save lives.
"They could actually bring solution, perfect solution, to the people over there," says Kohavi. "For the kids ... They can use the technology to filter water in the field. People are going days just to carry water. And all our solutions can be an alternative for that."

Matatizo ya udini na hasa dini ya kiissilamu kuonewa au kuchoma mabucha yameanza enzi za Mwinyi, yakaisha baada ya Ben kuingia,

back to the point kuchagua viongozi watano waisilamu leo bongo, ni dhihaka kwa taifa, halafu lazima uelewe hata Kibello aliyehamishwa ni Muisilamu pia, kwa hiyo ni SITA kwa mpigo, hizi ni dalili za uwezo mdogo wa rais katika kufikiri au kuelewa siasa,

sasa kama rais haelewi, je wananchi itakuwaje?

Maji ni uhai. Naamini kila mmoja anakubaliana na usemi huo kwani bila maji hakuna kiumbe chochote kinachoweza kuishi. Tunapokuja kwa upande wa sisi binadamu, kusema tu maji ni uhai haitoshi, bali maji safi na salama ndio sahii zaidi. Ili kuthibitisha hili, Ripoti za Ummoja wa Mataifa (WHO) zinaonyesha yapata watu Milioni 780 duniani hawana access ya maji safi na salama, na kila mwaka watu milioni 3.4 hufariki kutokana na magonjwa yanasobabishwa na matumizi ya maji yasiyo safi na salama.
Katika kulitafutia ufumbuzi hili, kampuni ya Kiizraeli iitwayo Water- Gen imegundua mashine yenye uwezo wa kuzalisha maji kutoka katika hewa.

Namna ifanyavyonkazi
Mashine hiyo ya kustaajabisha ijulikanayo kwa jina la Atmospheric water-Generation unit inafanyakazi kwa kupooza hewa na kugandisha unyevu unyevu (water vapor) uliopo katika hewa.
Baada ya maji kupatikana, hupitishwa katika vichujio (filters) maalum ambazo zinauwezo wa kuondoa takataka za aina yoyote ile, zikiwemo kemikali na vijidudu vidogo kabisa (microorganisms).
Baada ya maji huyo kuchujwa, hufikia katika hata ya mwisho ambapo huifadhiwa katika matanki maalum,tayari kwa matumizi.

Hutumia nishati ndogo sana
Moja ya vitu vinavyoifanya mashine hiyo kuwa ya kipekee zaidi, na kuifanya Kampuni hiyo ya Water-Gen kuzipiku Kampuni zingine zilizojaribu kutengeneza aina ya mashine kama hii ni kuwa na uwezo wa kutumia nishati ndogo kabisa kwa kuweza kutumia hewa iliyopoozwa iliyozalishwa ndani ya Atmospheric water-Generator ambayo huweza kupooza hewa nyingine inayoingia ndani yake.

Kiasi cha maji yanayozalishwa
Kwa kutegemeana na kiwango cha nyuzi joto na kiasi cha unyevu unyevu (humidity) kilichopo katika hewa, Water-Gen generator mashine inauwezo wa kuzalisha Lita 250 hadi 880 ( sawa na Galoni 65 hadi 210 za maji) kwa siku.

Madhumuni ya ugunduzi wa mashine nini
"Hapo mwanzo, mashine hii ilitengenezwa maalum kwa ajili ya Israel Defense Force (IDF). Lakini Jamii kwa ujumla inaweza kunufaika na mashine hii". Anasema CEO wabkampuni ya Water-Gen, Arye Kohari.

Je wanazungumzia lolote juu ya negative side of it? kama vile kukausha mvua baada ya miaka kadhaa ikiwa mashine hizi zikizalishwa kwa wingi kupita kiasi? najaribu kurejea yaliyotokea Ihefu miaka ya 2007>>08,

Technology hiyo ya zamani mkuu wangu, nilipita Arusha mwaka 2010 nikaziona pale duka la BrazaAfric hizo water dispensers ambazo zinatengeneza maji ya kunywa kutokana na hewa, lakini zenyewe zina uwezo wa kutengeneza mpaka litres 36 kwa masaa 24 kutegemeana na hali ya humidity ya sehem iliyopo..kama sikosei zilikuwa zinauzwa Sh 2.5m ...tuliwakuta pale walikuwa wakifanya demonstration yake..
