Well, if the goal is a secure home, I would start by throwing out all plans that call for significant amounts of flammable materials. No log cabins, no straw bales, and no stick-frame houses. That would leave you with rock, concrete (and its many cousins; papercrete, insulated forms, etc), earth (rammed, adobe, etc).
I don't have any experience with modern dome buildings.
I do really like the idea of an earth bermed and/or roofed building, though. It makes for good insulation and low maintenance, and it can help a building really blend into its surroundings. Ten feet of earth on a roof is probably way too much, though. The stuff is heavier than you might expect, and supporting 10 feet of it would require a huge amount of structure, with lots of loadbearing walls and/or pillars. the sources I've seen don't generally recommend any more than three feet on the roof (with the minimum for getting some effective insulation benefit being about one foot).
Another thing to consider for earth bermed buildings is that the earth will press horizontally against all the buried walls, in addition to the roof pressing down on them. So your walls need to have a significant amount of strength in that direction (and the forces get much higher when there's any groundwater involved). So, concrete tends to be the material of choice.
Is there a reason you suggest wind and steam power, but not solar?
