John Adolphus Etzler (1791–1846?) was a German engineer and inventor who immigrated to the United States in 1831 with a vision of creating a technological utopia. He was traveling with a group from Prussia, who included younger engineers John A. Roebling and his brother Carl.
Because of disagreements, the group broke up. Etzler and most of the group first settled near Pittsburgh, Pennsylvania. In the early 1840s Etzler and several dozen of his followers moved to the tropics, to set up utopian communities to use his inventions in Venezuela and Trinidad. He believed his inventions could work off natural forces and avoid human labor. Their efforts failed and many people died. Etzler survived but disappeared from the record.
Read this for my religion class. A whole load of BS…but I feel a bit bad for the guy. He had a vision. So much of this was just his mental math and ideas for things that he couldn’t even invent so it wasn’t really worth reading because it was just a lot of “10,000 tons of this will power enough xyz to feed 1,700,997 people” etc. I listened to most of it on audiobook so didn’t retain a lot anyways.
