The first Beis Hamikdash was built by Shlomo Hamelech (King Soloman), the wisest of men. Meaning, his intellect far surpassed the inventions of the industrial revolution, the cyber revolution, and whatever revolutions contemporary scientist can only speculate of.
Possibly, the Beit Hamikdash was replete with inventions beyond our times.
It is interesting to note the famous Ben Yehoyada in Gittin, that Shlomo Hamelech used to speed down the streets of Yerushalayim in a coal-powered car, and everyone suspected he was being carried by Sheidim.
The Midrash and Meforshim say that at the foot of King Shlomo’s thrown, there was a golden lion that would spring to life to guard the thrown from anyone other than Shlomo trying to ascend, and that birds would carry a Sefer Torah to him.
Perhaps the power of Kedusha will circumvent the need for electric in the Beis Hamikdosh.
Although, the pulley and irrigation systems in the Beis Hamikdash were not nearly as sophisticated as modern-day technology.
There are some that speculate that it is man’s purpose to live in harmony with nature, and avoid any technology that interferes with the cycle of nature- (an idea defied in today’s sedentary world).
Perhaps this ides is supported by the Jewish custom not to burry in a casket, but rather upon the earth, to encourage decomposition and land enrichment. The drainage through irrigation under the Beis Hamikdash, as well, works in harmony with this biological cycle.
As far as the manual, relatively unsophisticated, pulley-system, there were clear and open miracles that took place in the Beis Hamikdash on a daily basis. So there was definitely an intended extent of miracles and automatically-run things, and the beginning of requisite human effort in the Beis Hamikdosh.
-I am curious to hear the views of Sam2, rebdoniel, and WIY on this.
