What will be the price of one of those settlements?
There has been an evolving number over the past year due to different designs. Mainly the 25x25m platforms were estimated to cost around $10 million. But I've seen that they are doing different variations with bungalows and condos, so they might be priced differently.
Nothing will really be set in stone until all of the engineering and design is done which is the main bulk of what the ICO funds will go toward. But the goal is to average around $200k per person to live there.
How far away from the shore will those settlements be?
We are still vetting several locations in French Polynesia. I will personally be going to sites, likely in July, to do some depth testing, some aerial viewing, etc. to see how viable the locations are.
The plan is to find a location that is as calm as possible while still fairly close to shore within a protected lagoon. It would likely only be out a few hundred meters to begin with. They will also be taking into account the coral reef and ensuring that we locate it in a place that has zero impact (unless helpful) to the wildlife in the lagoon.
In Elwar we trust

Good to see that the person with who we can communicate directly oversees so many details and actively participates in lots of segments in the project.I agree that it is better for start when everything is being based on trial and error and finding best solutions for numerous problems to be close to shore if anything goes wrong or adjustments are needed.Hopefully those green organizations won't cause to many problems.
