Even glow plug won't work. It needs to be heated and compressed.

50 - 60m high yes. The power cabling in that building probably runs in the 1000's of Kilometers.
Heat is all that's needed. Just like oil. Compression does have benefits to make it easier.

But the 1000's of kms is not one cable. Nothing different ito power grids in other even higher buildings.

The highest structures in JHB are the Sentech Tower and the Hillbrow Tower. Both have lots of equipment at the top. NONE of them has placed generators at altitude in the towers. The logic is just completely missing and totally stupid to do that in a building.

On an aside: There is a lot of logic in not putting a computer room in a basement though. At a stage one year we joked about bringing out branded computer lilos. When water reaches the bottom it tends to dam up rather quickly if the leak is big enough :ROFL:

In the good old days, diesel generators were placed on concrete pedestals above floor level in a room either in the basement or at ground floor level. The ground floor being preferable for access etc. The room was, in fact, a "tank" precisely to handle a diesel leak!
Seems that the new millennials need to do a lot of learning about logical designs!

The maths is confusing but it checks out , thats why they make the cable going down thicker , so the electricity can achieve free fall speed quicker , the cable going up is thinner so it can build pressure quicker and force the electricity up.
Makes sense. We do the same in the fibre optic world to allow for sufficient data transfer.
