MacKay's work makes a complex subject simple, is certainly effective at unit harmonization in a domain (energy) where an array of units can be thrown around without any regards for ease of comparison. Given technological trends, maybe it makes sense for the next version of this work to be some sort of 'living' document/website, where calculations with changing variables (like efficiency of commercially deployed PV cells) change over time?
