The water shortage is now a global issue. I was very surprised to see so many special water purification facilities in Brave Blue Water. For example, I never thought that moisture in the air could also be extracted and used. In addition, the combustion products made from feces really make the domestic waste get full circulation, which is very good, but I still doubt the benefits of this operation, otherwise, it is still difficult to promote. Secondly, more information is required to ensure that the water purification box or membrane can indeed purify wastewater to drinkable water; thirdly, if the cost is too high, or higher than the cost of transporting purified water from afar, this technology is difficult to promote, especially among the poor. Other questions, such as what is the raw material for the production of the membrane, and is the cost high or low? What kind of waste will be generated by these technologies in the process of purifying purified water? In addition, does the energy required for the water purification box be large? How to deal with membranes after water purification? Are they harmful?
Even though some people are not in the water-shorted area and don’t use the water purification facilities, they can still save water by reusing the water in their daily lives. This is also a contribution to preventing the global water shortage and helping our future drinkable water protection.

Hi S!
I also was surprised to learn about the production of water through extraction of moisture in the air, like with the Majik Water project. I personally feel like the Sanivation project could be a potentially very valuable model, in that the "charcoal" produced from the feces byproduct is more cost effective than regular charcoal and produces zero carbon emissions (so great!) and how the cost of providing the Sanivation service is covered by the sale of these charcoal pieces. I am a bit worried about whether or not people would feel comfortable getting over the idea of using charcoal made from human feces though.
I think you have some really good ideas! I like the idea of even people in non water shortage areas using water purification facilities since I think this is a more global solution to the issue and is a good way of facing such big issues.
You've done a great job incorporating the technological aspect go the biological (sanitation) aspect of water accessibility for everyone. The reuse and recycling of water and reduced water consumption are certain things industries and humans should incorporate.
You've identified so many great ideas here! Your point right at the end is great especially – by reducing our water consumption we're reducing the energy needed for purification, the amount of chlorine and other sanitation products produced and polluted, and so on. I also echo your concerns about the energy and waste of purification methods highlighted in the film...the membrane technology strikes me as something that can get clogged and wear out over time, I'd be curious to learn more!
