as an investor in many projects one of the few things i would be looking at to even take a funds beg serious are:
single and final design
proper costing estimates
list of material suppliers
list of engineering companies worthy of fulfilling the contract

blueseed is not in the investment stage of a project. atmost they should be at the pledge stage. this is be cause with all their waffle. they are still talking about it as an IDEA. not a plan.

im sorry but blue seed has been showing off this idea since 2011, looking for investors from different walks of life. business people, developers, banks governments, and yet still do not have the funding. so they obviously cant be on the right path if they cant find enough investment after 2 years and here is why they cant really get any creditble funding:

after 2 years he has still not even come up with a final design to then make proper blueprints to atleast get the materials costs/engineering labour to have an accurate idea of funds requirements, instead he has 4 design idea's.. which even during his writing of these posts he has made comments that things are not finalised by mentioning changes/adaptations that are possible.[1]

i think that not having a final design he cannot accurately know the costs or the timescale to say it will be in the water by summer 2014.[2] and as for their series A funding which was $500k in 2011[3], they could have got the money easily from under 10 entrepreneurs that may wished to go to the UK and convince them to move near silicon valley[4]

and where suppliers deal with FIAT, i think asking for any bitcoin investment is just absurd. what this OP should be doing is going to FIAT investors, but just highlight the project as requiring bitcoin once the project has finished, to be used as a functional currency on the ship. as its not strictly required for the building of the ship.

in short, im not going to invest.

the idea is good, but i feel that he is playing on bitcoiner's dreams of a sanctuary place to use bitcoin[5]. to grab money for his bottomless pit. whereby it will be filled with office staff from multiple countries all working on american/silicon valley projects for dollar without being on mainland due to visa restrictions, not a true free society/country of bitcoin.

once this project is in the sea, i and many of us would be happy to convert main land funds for contract work into bitcoin so they can be used on the ship. but not investing bitcoin just to be sold off instantly into fiat to fill the OP's pockets before a blueprint has even been drawn up

[1]Which solution we'll choose is a tradeoff between the initial capital investment and operating cost.+multiple other examples of plans that can change
[2] As long as we raise Series A funding on time, Blueseed should be in the water during the summer of next year.
