Iron Age brochs, drystone-built towers unique to Scotland, are typically 18m in external diameter, 9m internally, and 12m to 14m high. Calculation of the volume of stone required for the construction is relatively simple. Calculation of its standard bulk density, only marginally more difficult so that the mass of stone involved can be calculated with confidence. The calculation of the number of kWhs of energy required to quarry, lift move, horizontally and vertically and place into the monument...
