Desirable school subjects

24th January 2020 Last week, Basic Education Minister Angie Motshekga said that select schools would be piloting subjects such as robotics this year and, if successful, the subjects could be rolled out to public schools as early as 2021.  This is the most uplifting news I have heard since it was reported that... 

Becoming an acoustics engineer

17th January 2020 I am a qualified electrical engineer. There were 105 students in first year engineering when I enrolled at university (if you ask my staff, they will tell you this was shortly after the Manumission of the slaves and just before the great trek). At the beginning of second year, the number had... 

The idle thoughts of an idle fellow

13th December 2019 There is a lot of gloom and doom about in this country. In the professional community of which I am a part (that is, architects, builders, engineers, developers, and so on) I ask: "How's business?" The answers are not positive. In 2010 World Cup days, we were all massively busy. I wrote then that... 

Fake science

6th December 2019 In the film A River Runs Through It, we see a young Brad Pitt, acting as Paul Maclean, being home-schooled by his father, Reverend Maclean. Brad is told to write an essay. He does and brings it back to his father to read. He reads it, hands it back and says: "Good. Half as long." So Brad goes off... 

Staring you in the face

29th November 2019 Wind power and solar power are not available all the time. Many assume that the interconnected power system it is some sort of system which has a huge storage dam full of electricity that is tapped to supply a load. Thus, when a windmill or solar panel contributes to the dam, this is a great and... 

The World Cup

22nd November 2019 Years ago, Engineering News publishing editor Martin Creamer told me I could write about anything in this column, as long as it was not offensive. So, the World Cup rugby. Not the recent event, the one in 1995. I have lived my life following a plan. I have stuck to the plan and have hit most of... 

Hannover Fair

15th November 2019 "Come on Terence," said Harry, "don't you know about the Hannover Fair ?" "In Hannover, Germany?" I asked. 

2003 Cricket World Cup

8th November 2019 I was going to write about the latest offering from national government, the Integrated Resources Plan (IRP). This is the document that sets the way forward for the energy generation policy for South Africa until 2050. However, the document is  complete rubbish. Moonshine. Hopelessly unrealistic.... 

The dinosaur falls – Part 2

1st November 2019 In my last column, I wrote that State-owned electricity utility Eskom has been most comprehensively messed up. A combination of black economic empowerment, government incompetence, employee incompetence, overemployment, theft and corruption and renewable energy have all combined to bring the... 

The dinosaur falls

25th October 2019 State-owned electricity utility Eskom has been most comprehensively messed up. Stronger words apply . . . but anyway. Black economic empowerment (BEE), government incompetence, employee incompetence, overemployment, theft, corruption and renewable energy have all combined to bring the dinosaur...
