@Bob, you are quite new to the idea of ocean colonization and you will be surprised what i have already figured out and a strong grip on when it comes to “solving the bottleneck of ocean colonization” - at least 95% of the things we will do in the construction phase1 are things where i have been there and done that already. So in this phase we will be far from “knowing nothing and start to figure it out” - this is why i will be in charge of the construction… on the long term in phase 2, 3, and beyond of course you are right - many things we do in Marinea will be “first of its kind” 
- but like any resposible company we will definitly limit the “unkowns” subject to R&D (research and development) to some 15% of our business volume. Doing different would be irresponsible in front of our shareholders exposing the project to failure. What differes Marinea most from other “enthusisastic ocean colonization projects grouped around talk and wild ideas” is that we are a group where BUSINESS and SHAREHOLDER VALUE is written in major capital letters, and where people who have been there and done that sit in the “engineering advisory board” and take the key decisions…we are definitly not “floatie-goofers” trying to figure it out"…We are business people getting a foothold in ocean colonization…i know that you know that but from what you said in the post the 250 people reading this so far might have got another impression.
