How are you going about providing clean potable water to the residents? Normally, potable water is provided via water mains on land, and are sterilized with chemicals such as chlorine . However, the people behind the project seem adamant that climate change is a problem, and that you could relocate relatively easy. Then how are you going to transport your potable water?
You could go the desalination route just like cruise ships do, although this has proven costly. Eventually, you could have the need for a lot of potable water which might not be easily processed through desalination. Desalination has also been linked with climate change which I'm sure the people behind your project don't want to actively encourage.
I'm guessing that you will be collecting rainwater for a source of potable rain water with the involvement of American Rainwater Catchment Systems Association. Although, I would have my concerns about using rainfall for potable water. For example, it's very difficult to determine the amount of rainfall that might happen, and whether it will be enough to supply your ongoing residents. You could have dry days/weeks etc which could be a massive issue. What are your backup plans if rain fall doesn't alone provide enough to your residents?
What sort of capacity will your water reserve be holding?
I've skimmed your whitepaper, and haven't found you going into detail about water systems, water consumptions and contingency plans. I consider water to one of the most important aspects, and one which is often overlooked. I'm also interested in the system you will be using to determine how much maintenance, and how long it would take for the initial investment to prove while.
All great questions and we have a full team that has been focusing on nothing but water/waste for the past year. Since I am in the blockchain group I will not try to cover all of the insanely complicated things those guys discuss in their group because I just peeked into one of their meetings once and sat through three hours of talk about poop and the stages of how it goes from stinky to useful soil.
I have heard a few things in the general discussion about rainfall catchment and storage being built into the design and a very heated discussion about not allowing any higher salinity to return to the sea than we take out (minimal impact vs zero impact vs positive impact, etc.). In the lagoon we hope to leave it better than when we arrive.
Fortunately the teams are putting together an easy to understand infographic about more of the design elements (the whitepaper is more about the currency and general idea of the company than anything specific about the design). This will also include a full report by each of the design groups that they submitted at the end of 2017 with their recommendations.
And as with all of these systems we will initially be very close to land so we will certainly have backups in place as we evolve and grow.
