Riots and strikes

17th August 2018 We are in an era of strikes and riots. Workers at State-owned power utility Eskom have been on strike for weeks and have just settled, the taxi drives are on strike, the public workers union are threatening a strike, platinum workers are on strike, and so on. All strikes happen with the usual... 

Playing with mental clarity

10th August 2018 There is a serious disconnect between engineers and production idea people.  Production idea people want to innovate. They want a new thing every year. They do not want improvements, they want change – out of the box! Dynamic! Some of these ideas are good but few are ground-breaking. What is... 

Professional fees

3rd August 2018 You can get advice from a fairly good consulting engineer at a rate of about $700 for an eight-hour day which is near enough to R1 200 an hour. This would be a person who is registered as a professional engineer and has at least 20 years' experience. The rates that individuals and consulting... 

Engineering gut feel

27th July 2018 So, there I was at a site meeting. As acoustics engineers, we had designed a roof build-up for the building which was under construction; firstly, to comply with thermal insulation requirements and, secondly, to comply with sound insulation requirements. We had been called to the site meeting to... 

The elephant in the substation

20th July 2018 Everybody knows that renewable energy is great for us all: it is free, it does not pollute, it keeps big bad Eskom on its toes and it  represents huge investments in South Africa. What is there not to love? The bids for various wind power farms (this is the amount for which Eskom has to buy power... 

The war is over

13th July 2018 Alan Campbell mentioned to me that, since this column is titled Electrically Speaking, it really should be about electricity. Good point. Well, water is normally supplied by pumps, and pumps work on electricity. So, joining the dots, this column is about water. Or more specifically the recent... 

People say . . .

6th July 2018 In the Santam television advert, the ever-so-twee sweet likkel girl says that the first person to live to 200 has already been born. Well, she would know, wouldn't she? These sort of statements are whipped out by the media in order to shock and amaze – almost so that we can say how clever we... 

Unbundling Eskom

29th June 2018 It should be evident to everybody that State-owned electricity utility Eskom is in the following condition: (a) The road transport coal supply contractors have for years been ripping off the system – the trucks get loaded with good-quality coal, which is driven to an export depot. They then pick... 

Operation North Pole II

22nd June 2018 In last week's column, I told of Abwehr officer (German intelligence officer) Herman Giskes, head of Abwehr Section IIIF, who set his mind to capturing British agents who were either dropped by parachute into Holland or landed by boat. This was his plan: the Abwehr should concentrate on trying to... 

Operation North Pole

15th June 2018 Once upon a time, I tell the youth, there was a world war called World War II. Germany and Italy were fighting the UK, France and the US. The Germans invaded and occupied France, Holland, Belgium and Norway. The British decided to disrupt the German occupation of France and Holland by parachuting...
