Not just wool – the whole darn blanket

19th July 2019 There is no doubt that there is money in the renewable-energy business. Few businesses have the general public so much in their favour, few have so much positive propaganda over their competition. The business model is so beautiful, at least in South Africa – they can generate and sell energy... 

Electric vehicles

12th July 2019 Everybody wants to do his or her bit to save the environment. Some want to be a bit more public about it and so graduate from recycling their rubbish to owning an electric vehicle (EV). It is the ultimate 'green statement'. As you pull away noiselessly, the vehicle hums: "Yes! I care! Vooommm!"... 

CEO of Eskom

5th July 2019 Dear Mr President, Members of Parliament and readers of Engineering News. May I present the new candidate for CEO of State-owned electricity utility Eskom? It is myself, Terence Eric Mackenzie Hoy. I am the ideal candidate, for the following reasons. 

Big Brother is still watching

28th June 2019 Nineteen eighty-four is now 35 years ago. It is also the title of a book by George Orwell, 1984, published 70 years ago. The book begins: "It was a bright cold day in April, and the clocks were striking thirteen." And here we have an immediate clue – somebody has altered the means of keeping time... 

Business lessons from life

21st June 2019 Once upon a time, there was a ship called the Essex. She was a sailing ship, rigged out as a whaler. Whalers were use to kill whales and recover the whale oil for use in oil lanterns and for other applications. Over the years, whaling ships were sunk by whales – at least six of them. The Essex... 

What we need is a good war

14th June 2019 I am tired of hearing about all the soft ways in which we can 'stimulate the economy' and 'create jobs' and reduce inflation. The fact of the matter is that government has comprehensively messed up every single industry that it can and is now looking at the broken pieces of the economy like a... 

Egyptian geese and aircraft beam navigation

7th June 2019 I have a very tall pine tree on my property in Pinelands, Cape Town. On many past mornings, it has been the roosting place for a pair of Egyptian geese. Now understand – it is not their nesting place – they arrive at daylight and start honking soon after. The honks go on for about 30 minutes,... 

Both barrels: govt and small business

31st May 2019 When Engineering News publishing editor Martin Creamer gave me the go-ahead to write this column, he set down certain topics to be avoided. Politics was one. However, I am allowed to criticise government, so now I am going to give them both barrels. Fortunately, the election is over, so whatever... 

Dear Mr President

24th May 2019 Happily, if I google 'Ramaphosa', I get 12.7-billion hits. If I google 'Mackenzie-Hoy, it is 8.1-million, and if I google 'Alan Mulally, I get 462 000 hits. So, I am more famous than Mulally and about 8% as famous as our President. I doubt if the President or anybody in his party has the vaguest... 

Plague of invisible rats

17th May 2019 This column is for David and Linda Odd. A potential disaster exists in the form of the coming plague of invisible rats, which are responsible for sudden crop failure, power outages, outbreaks of diseases and unexplained deaths of domestic pets. Government is paying experts to find a solution....
