In this book, the author covers many aspects of hydro energy. He starts off by looking at classic high pressure systems and then moves on to household systems, low and high head. He touches on the history of hydro energy and concludes with a section on the future of hydro energy.
I find this to be a joke, written in sowing the seeds, i bursted in laughter (more sarcasm and wit but yeah..). Sorry for the rather bizarre humor:
“ i read about a professor recently who did a basic study of the deserts of iran and iraq. I do not remember his name anymore, but he came to the conclusion that it would be better to leave the deserts as they are, and refrain from intervening. There is also a theory that it would be better to let Africa’s deserts and the resulting public health problems take their “natural" course."
