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... 

Death of the small consulting practice

18th October 2019 I am not sure how much we are owed in total. This is 'we' as in my consulting practice. A figure of R1 030 000 springs to mind. Certain debtors do stand out. There is the dear old North West provincial health service which, with our acoustics and noise control design built into the new Bophelong... 

Large storage batteries

11th October 2019 Before cellphones, the only rechargeable batteries were NiCad batteries, and they were not terribly good. There was a drive to come up with something better, and so the lithium-ion battery was invented. It is a good technology and the charge and discharge cycles are quite efficient. A similar... 

Outsourcing and insourcing

4th October 2019 The wonder of politicians is their extreme stupidity. Somebody once explained to me that rocket scientists know lots about rockets but not much about anything else. Knowing lots about one thing. They do not know about warheads, for example. So, a less intelligent person coordinates the warhead... 

Power system stability

27th September 2019 Power system stability is the degree to which a power grid continues to supply power after an unexpected event. An example: he Zambia power system has a demand of about 1 900 MW. Thus, at any one time, generators with a combined capacity of 1 900 MW will be generating into the system, with the... 

Robot wars

20th September 2019 Daniel Faggella is the founder and CEO OF Emerj. He is an expert on the competitive strategy implications of artificial intelligence (AI). He writes: "Over the last two years, there has been a general 'uptick' in media attention around the risks of artificial general intelligence, and it seems... 

Under the sun

13th September 2019 I was on a Brazilian navy ship. I had been employed to design some noise-reduction measures but, as soon as I was on board, I was hustled down to the main electrical control room by the ship's engineer. He could speak no English and I no Portuguese. The ship had three diesel generators running...
