The island (Nananu-i-Cake, pronounced roughly "nah-nah-nuh ee tha-keh") is less than 750 meters off the coast of Fiji's most populated island, Viti Levu, so piping in water, electricity etc and ferrying in workers is eminently achievable. Of course, the fact that the video doesn't mention any of this, much less trivia like the location of the bloody island, is a strong clue about how seriously this project has been planned and how seriously we should be taking it.
