Geoff, interesting take. I did not see the show, but will look for it in re-runs. I believe that Mr. Wallington is truly able to pull this off, but what are the chances of having an engineering mind like his, without the aide of previous modern marvels to observe showing up in ancient Eygpt? I don't know who or what built them, but it seems odd to me that they wouldn't have also built dams, sustainable cities and large scale food-producing systems to go along with it. Plus, this fabulous technology only shows up in another continent with the south and central American indians? Again, they were simple savages except for their un-real calendar and the clear understanding of the stars...they must have all been from Detroit, the place keen minds congregate!
Actually, they were smarter than we are. They knew that food production is best done on a small scale. They knew that if they didn't built a dam, they would get the Nile to flood every year, clean out the old mess, and dump lots of nice free fertilizer on the farm land for them. And it would have all those nice trace minerals in it.
And their cities were more sustainable than ours were - built with natural materials, and small enough that they didn't need petrochemical powered transportation. And that the flood didn't really damage things much.
I remember a few years ago talking to an older Egyptian guy who remembered how the vegetables tasted before the Aswan dam was put up. He said that the ones that were fertilized with Nile river silt from the flood tasted much better than the ones grown with artificial fertilizers after the Aswan Dam stopped the flooding.
As an engineer, mechanical machines like levers and such that we are talking about are relatively easy to built. What has taken the slow accretion of knowledge is the extractive, refining, and machining industries. If you look at engines, for example, you really need modern machine tools, modern metallurgy, and modern petroleum refineries.
Bessemer's process - the oxygen furnace, and the electric furnace, the electrical processing of aluminum, all that refining of high octane fuel that helped us win WWII, thin wall castings, improved lubricating oil, improved bearing metal, modern heat treating, and on and on, a whole bunch of knowledge needed to get the knd of propulsion units we have now.
Let's not even talk about turbine engines.
The reason they used to build straight-8s, for example, is because they couldn't built a crank that would stand the concentrated stress of a high output V8. And they needed lots of bearing area, because the bearing material and the oil couldn't handle much PSI either.
Leonardo Da Vinci probably could have built a helicopter if he had had a modern internal combustion engine. He understood the machine, he just didn't have the technology.
