I will guess humanity made boats before inventing the wheel canals came before railways 1 hp could move 100 tons mile after mile I was up on Armory and discovered an ancient dried up canal associated with an old copper mine. It was about 30 inches wide and about the same depth, it meandered around the side of a hill to the edge of a cliff and was at least 1/4 mile long and several hundred years old. An interesting relic showing the importance of material movements using water as a means of transport due to the lack of friction.

Dear List, am neither an engineer nor a physicist, but a biologist. I made the bservation that nature did not evolve wheeled locomotion because a mooth road was a prerequisite for wheeled transport. Even humans, ho developed wheeled transport, use it only on roads or rails and not lsewhere. . ours .D.Karve On Mon, May 30, 2011 at 4:33 AM, Arnt Karlsen <[email protected]> wrote: On Sun, 29 May 2011 10:59:55 -0700, Henri wrote in message <[email protected]>: ..well, this list speaks volumes for itself. ;oD > Never know a bird brain could evolve to that > > Sent from my iPhone > > On May 29, 2011, at 7:08 AM, Jeff Davis <[email protected]> wrote: > _______________________________________________ asification mailing list to Send a Message to the list, use the email address [email protected] to UNSUBSCRIBE or Change your List Settings use the web page ttp://lists.bioenergylists.org/mailman/listinfo/gasification_lists.bioenergylists.org for more Gasifiers, News and Information see our web site: ttp://gasifiers.bioenergylists.org/
