Abstract
Millions of people suffer from a shortage of fresh water: the available resources rapidly reduce their capacity with the growing demand. Shortage of fresh water in several regions of the Earth is becoming a serious problem posing a threat to the mankind evolution and the environment conservation.
Water and energy scarcity are two major global challenges facing modern society. Right now, almost one-fifth of the world’s population is living in areas with water scarcity, and another 1.6 billion people are living in economic water scarcity areas because of technical or financial limitations to getting freshwater even when water is available. So, water treatment techniques employing solar energy are deemed attractive for producing fresh water from impotable water sources, including seawater, river/lake water and contaminated water, by safe and sustainable methods.
Solar-driven desalination in the countries with hot and arid climate can employ abundant and free solar energy to produce freshwater from natural water sources, making this technology a promising one to solve the water scarcity problem.
Besides, solar-driven zero liquid discharge (ZLD) desalination from waste brine water has recently emerged as a new important application of solar evaporation. Compared with conventional ZLD desalination technologies, solar-driven ZLD desalination produces solid salt as the only byproduct and uses sunlight as the only energy source, making it less energy intensive, more cost-effective, and affordable.
This paper considers a concept of a small self-powered solar-driven multi-stage ZLD desalination plant based on film evaporation drums and having a desalination capacity of up to 1100 liters of freshwater per day.

  • Andrea Rossi

    Lars Lindberg,
    Thank you for your kind attention to the work of our Team,
    Warm Regards,
    A.R.

  • Lars Lindberg

    Dear Andrea,
    Even if the EV test fails, wich I dont think it will, your technology is still valid, and therefor it will change the energy view in the world. So even if I understand you are nervous, the start of the new energy view have been started and can not be hidden much longer. It has been very interesting to follow your work through the years. Thanks

  • Andrea Rossi

    Sam:
    Yes, it is what we are doing,
    Warm Regards,
    A.R.

  • Sam

    Do you think your technology
    would be compatible with fast
    charging EV batteries?

  • Andrea Rossi

    Lass Lindberg:
    The issue is more complex.
    Warm Regards,
    A.R.

  • Lars Lindberg

    Dear Andrea,
    If this test will workout and the e-cat will be able to charge Evs then the need of batteries will go down I suppose. You only need batteries for buffer the EV. Do you think that this correct?

  • Andrea Rossi

    Lars Lindberg:
    Yes,
    Warm Regards,
    A.R.

  • Lars Lindberg

    Dear Andrea,
    Before the run in october, Will you make a test run wich is about the same as the real run in october?

  • Andrea Rossi

    Christian Scholl:
    Thank you for the link,
    Warm Regards,
    A.R.

    Hello Andrea Rossi

    The last interview of Nassim Haramein
    He presents the ISF (international Space foundation)
    An international foundation to develop vacuum energy and antigravity

    Best regards

    Lars Lindberg:
    No, it must be proved; base on our simulations and projections the lifespan ahould be 100000 hours, but we cannot guarantee it.
    Warm Regards,
    A.R.

  • Lars Lindberg

    Dear Andrea,
    It must be very difficult to predict the lifespan of the e-cat. Is it a 100.000 hours guarantee?

  • Andrea Rossi

    Lars Lindberg:
    It depends on the power of the Ecat and the ratio between the capacity of the battery and the energy demanded during the transitory,
    Warm Regards,
    A.R.

  • Lars Lindberg

    Dear Andrea,
    if I use a lot of energy in the EV for a while, will the E-cat be able to keep the battery from discharging or do I have to go slower for a while to let the E-cat to chatch up?

  • Andrea Rossi

    Lajos Kelemen:
    For T< 20°C is necessary a heater, that can be powered by the same Ecat; obviously this issue is relevant only in outdoor applications, like, surely, EV. Warm Regards, A.R.

  • Lajos Kelemen

    Hello Mr, Rossi,

    The ecat specification says:
    Operating Temperature Range -20 °C to +60 °C

    What happens when the temperature drops below -20 ?
    Will the ecat stop working?

    In northern countries there can be below -20°C so this is important info to know.

    thanks
    Lajos Kelemen

  • Andrea Rossi

    Lars Lindberg:
    The module will be fit for all,
    Warm Regards,
    A.R.

  • Lars Lindberg

    Dear Andrea,
    will the e-cat be able to charge any EV or will the brand now doing the test with you have exclusive rights?

  • Lars Olov

    Dear Andrea, I suppose you have figured out how you will get out more power from a smaller area when it’s needed, like in the case with the Ev. So you don’t have to use a lot of small 10 Watt e-cats I supposed the container material for a 10 W e-cat would take up a to much space, when you know that you will use for example 20kW anyway.

  • Andrea Rossi

    Lars:
    We are working on it,
    Warm Regards,
    A.R.

    Lars Olov:
    Please formulate your question more precisely,
    Warm Regards,
    A.R.
    ..
    Do you think an e-cat charged EV can continuously maintain highway speeds without needing to stop and charge?

  • Andrea Rossi

    Lars Olov:
    Please formulate your question more precisely,
    Warm Regards,
    A.R.

  • Lars Olov

    Dear Andrea,
    Have you planned how the E-Cat will charge the EV? Will it be enough to continue driving without charging?

  • Andrea Rossi

    Irina and Vitaly Uzikov:
    Excellent paper, very interesting also considering the eon transition that will probably cause fresh water shortages.
    Warm Regards,
    A.R.

  • Dear Andrea!

    To demonstrate the principle of operation of film evaporation drums involved in a desalination plant, I suggest that you familiarize yourself with the video on YouTube at the link
    https://www.youtube.com/watch?v=_xdBJkzjHTw&t=262s
    E-cat EV can be used to power the drum rotation drives anthe control system of the desalination plant. This is very important because it is desirable to rotate the drums constantly to prevent scale deposits on the walls, even when there is no wind and sunlight.
