as this starts to go slightly offtopic I enjoy posting also this wikipedia reference which might be interesting in the context: http://en.wikipedia.org/wiki/Earth%27s_internal_heat_budget Interestingly the 47 Terawatts of thermal power arriving at the surface from the interiors of earth is just 0.03% of all superficial thermal power (because 173000 TW or 99.97 % are coming from solar radiation). cheers, Martin
