I’m doing a bit of light reading this afternoon. (Well, it’s actually a hefty volume that weighs about 4 kilograms.) HVDC Power Transmission Lines Book is an Eskom publication from November 2021 and a copy has landed on my desk, courtesy of one of the principal authors.
If you’re wondering why on earth I would be interested in High Voltage Direct Current transmission; and — more importantly —why you should care, let me give you some bullet points.

Seven years ago last night, I got on a plane from Johannesburg to London. I landed the morning of 1 April, launched this amazing product I had co-designed with the BBC, did this panel discussion as well as two TV appearances, and flew back that night.
The idea of a news bulletin targeting an educated young audience with a short attention span seems like a crazy idea today. But BBC Minute (or #TWISS — The World in Sixty Seconds as my then team dubbed it) has thrived.

Multichoice has come under flack lately from keyboard warriors after Russia Today fell off the company's DSTV offering.
“Sanctions imposed on Russia by the European Union [EU] have led to the global distributor of the channel ceasing to provide the broadcast feed to all suppliers, including MultiChoice,” Multichoice was quoted as saying.
Hmmm, I thought, so why not simply downlink the Russia Today signal directly via satellite?

Some years ago, I drove from Johannesburg to Lüderitz on the Namibian coast for a friend’s wedding.
As I approached the town, the dysfunctional railway line which once linked Keetmanshoop to Bahnhof Lüderitz (as the Germans who built it in 1906 called it), frequently vanished under shifting desert sands. In the town, the station itself was derelict.
Construction of the railway line by the Germans took 9 months. Let me quote a well-documented historical account :
