This type of discussion is pretty pointless anyway, but since we started ;-) I have a few comments about second article "The boat engine is worth 33500 Egyptian slaves" First ancient Egyptians did not use slaves. Workforce in Old Kingdom which build pyramids were free men. Later it was more similar to feudalism. (BTW: women had more rights in Ancient Egypt than most women in 20th century) Also towing is not really necessary on river Nile. There are northerly winds for most of year, so one could just use sail to travel upstream. And third; 'Pharaoh Nile Express ' actually exist, but it had only 30 rowers :-) http://en.wikipedia.org/wiki/Khufu_ship http://en.wikipedia.org/wiki/Khufu_ship
