Rain house

    The Rain house will be made of a special bio-concrete that will allow it to filter rain water.
    The concrete will be both PH neutral and bio-compatible with water, which will enable it produce sun-distilled water naturally.
    Rain water is believed to be the purest source of freshwater, and bio-concrete technology could democratize fresh water supplies by providing access to affordable clean water for small and big scale users, from families to big companies, leaving the smallest possible ecological footprint in the process.
