Linear "Road town" proposed in 1910 is still a neat and somewhat appealing idea. But it does remind me somewhat of a cruise ship...
"It is linear city housing a thousand people per mile is surrounded by farmland, so people can move along its length to get things that are made elsewhere, but one need only go perpendicular to the town to find (or grow) food. Bountiful electric power will make it all possible."
More about all that here.
Or you can read the entire proposal here on Google, or below.
