Making water

Clean drinking water is scarce in many parts of the world – especially in hot areas. According to the WHO 780 million people worldwide do not have access to clean water, with 3.4 million deaths related to it.  Though in many dry regions in terms of precipitation, humidity is often particularly high. For these regions, the Israeli start-up Water-Gen has developed a device that draws water from the air. A power connection is required but the device is arguably more energy efficient than previous models because it uses already cooled air to reduce the temperature of incoming air. Thus far the company has worked with the military of various countries, but now the civilian population is to benefit.

The apparatus called GENius condenses humid air on a cool core, filled with artificial leaves of plastic. It seems like an easy thing to do because we see it happening every day in summer with air condition but the tricky thing is to do it efficiently. Approximately 300 watt hours of electrical energy per liter of water produced are required. Water-Gen also uses the same process in dehumidifiers and tumble dryers.

GENius is supplied in several sizes – for schools, hospitals, villages or only for one family. It is still being tested in cities such as Mumbai and Mexico City before the launch in late 2017.

    This may be very useful in Africa or in other dessert fields with no water supply. If it will be improved in industrial size, those devices may be used for agricultural irrigation too. There are many agricultural fields convenient for plantation but lacking of water supply. It can be a good solution for this problem.

    I think that this can be a very useful idea. With global warming this problem is constantly increasing and so if tests will have a successful conclusion, this product may be used for similar activities. This service might be able to help people without clean water, providing a service for the whole community. Furthermore, if every family possess one of this apparatus the costs of water would also be significantly lower than normal bills.

    Ok, certainly it is useful, it is a nice idea, it is more efficient than previous models but how much is this machine? Because this technology has been thought for poor and warm areas. So, I have two questions:
    – Can they afford it?
    – In case they can’t afford it, do they have government support?
    Let’s say that they may afford it. Is it a permanent solution? No. Unfortunately this kind of technology are so useful as temporary, because it gives to you the way to survive but survival is not living.
    So, these areas need government support to grow and improve the situation otherwise they are bound to a bad and recurrent fate, or rather get something to survive but not to live until you don’t get a new technology to do the same thing in a different way but without changing the real condition.

    For sure water is a hot topic now. I mean it’s hot for a long time now, starting with water privatization and water trade, which are terrifying to me.

    That’s definitely something to monitor, if Stephen Hawking points how bit the issue is. He alarms that in sub-Saharan Africa there are more people with a telephone than access to clean water. That’s mind-blowing! He says the future of humankind is away from Earth. So maybe instead of buying devices like the one you mentioned, we should start preparing for going into space and living on Mars 😉
