I am currently teaching a group of electricians from a company who are all South Africans or Zimbos to update to the 18th Edition.
We were working through the different types of earthing systems and I asked what did the use back home. The answer came TT. I asked what was the soil like and how deep and how many rods did they use. I will not try to mimic the accent or their terminology but words to the effect of, " We dig a big hole with a digger, lug a conductors on to a car or lorry engine and drop it in the hole with the digger and back fill".
Now I thought that was a brilliant idea given the surface area of a car engine dropped in to a deep hole. That would be ideal for an earth for my amateur radio transmitter assuming SWMBO would not object to a large hole in the front garden.
