Introduction


I am Chris Kloppers and I have a Master of Engineering degree from the University of Pretoria, South Africa and a PhD degree from the University of Stellenbosch, South Africa. My biography appears in the Marquis Who’s Who in Science and Engineering. My award* winning PhD cooling tower research is published in leading international journals and international conference proceedings. I also worked for Sasol (NYSE Code: SSL) as a senior mechanical engineer.
