ok, a little late answer... :) Well, first of all, the structure is not typically Roman, the Greek as well as other ancient cultures very early found out about the advantages of that design when it comes to visibility and audibility. Second, Germanic tribes were not that "rag-tag" as often imagined at all. They had a strong liking for colorful and ornamental jewelry. And calling them "warring" doesn't do them justice at all. The Romans for example were much more into warmongering as the history shows.
German history classes begin with stone age and end with the 1990s. An unproportionally big part of course covers the time from 1933 to 1945. That darkest of all times is depicted in detail and not leaving out the atrocities done by Germans. The goal is to clarify not glorify what happened then and why. To prevent anything similar happening again.
I remember being there around 20 years ago. I was staying in Heidelberg for some weeks and got dragged along to some birthday party of a friend's friend. He did it up there and it was kinda fun being in this huge arena at night, having some beers and eating what everybody had brought along. At some point the police arrived, but didn't interfere. They just watched and quietly left. It turned out that guy had birthday the very same day as the "Führer", April 20th. I guess the police saw it was no "Führer's birthday celebration", but just some more or less alternatively looking students. :)
Newer diesel generators typically run at 1800RPM/60Hz, while many older ones ran at 1200RPM/60Hz (or less) A modern 50Hz diesel generator runs at 1500 RPM, an older one at 1000RPM, etc.
While your small portable generator may run at 3600 RPM, the generators in a power generator station such as this do not. Although 60Hz for 60 seconds is 3600 cycles, this does not determine generator rotational speed. Rotational speed is determined by the number of poles in the generator. A 2 pole generator will make 60Hz at 3600 RPM, a 4 pole at 1800 RPM, a 6 pole at 1200 RPM, an 8 pole at 900 RPM, etc. At one of the generating stations I work at, our steam turbine turns at 4458 RPM, goes through a gearbox (with a reduction of 4.953:1) and turns the generator at 900 RPM.
Everything EE mentioned is spot on.
