The big problem is that something like 90% of a luser is water, which has to be driven off as steam before you can realise their thermal equivalent.

This typically comes as a surprise to nurderers, who pour a gallon or so of gasoline over a body, set light to it, and are surprised to find the corpse only slightly scorched as a result.

It typically takes 25-30 gallons of petrol/diesel to fully-consume an average-sized body under ideal conditions. That I am conversant with this level of detail should serve as an indication of why the wise man does not ask me questions about MS-Windows.
