If the amount of precious metals we have found on land extrapolates to the ocean floor, there is a vast wealth of minerals down there to take.

I am not an engineer but I would say the 2 biggest challenges to overcome are high seas and the stress put on the structure by wave action, first high seas could flood the compartments of the structure and sink it as well as wash people over bored. And 2ed the motion of the waves could rip the whole thing apart. One question that you have to consider is how big do you make your platform. I saw i video on youtube that you might find interesting, il link it if you want.

One major obstacle is that we cannot breathe water, unlike fish.
There has been work done on artificial gills, to allow dissolved oxygen to be captured for breathing, but the designs thus far are quite bulky and power hungry, as they require a lot of water per breath.
A better rebreather that would provide say a weeks underwater dwell time would be transformative imho.

There are significant amounts of ocean area that have been rendered suitable for human use.

In some instances dykes have been built to isolate a section of ocean. The water is then pumped out leaving the ocean floor available for use. http://geography.about.com/od/specif...st/a/dykes.htm

In other cases material is dredged from the ocean floor and then re-deposited in another place to build up artificial islands. http://en.wikipedia.org/wiki/Palm_Islands

There are other similar efforts going on elsewhere. In each case though the primary resource they are after is usable land area, not mineral resources.
