Terms:
Tradition - A contiguous cluster of power generator blocks. All blocks must be face to face, edge or corner contact does not count.
Bounding box - The smallest imaginary (cuboid) box that would fully encompass the tradition.
For a given tradition of power blocks where the bounding box dimensions are x,y,and z, and where there are n total number of power blocks in the tradition:
power= 2000000*(1/(1+(1.000696)^(-((x+y+z)/3)^(1.7)*(1/3)))-.5)+(25n)
