JF Ptak Science Books Post 2389
These spectacular images of monumental monumentality appeared in the December 1916 issue of Popular Science Monthly. The author Frank Shuman (1862-1918) had some major inventing chops, not the least of which was some very forward-thinking work (in theory and practice) on solar power (one of which was a solar powered steam engine and another a liquid O2 propulsion system for submarines), so these suggestions for gigantic land battleships came with a fair amount of gravitas. This is some grand thinking, and as Shuman tells us, the beast below would weigh about 5,000 tons (the weight of several hundred Sherman tanks1) and would roll along on 200' diameter wheels. Unfortunately, outside of seeing some sort of (steam) power plant, there is no mention of how those wheels would be turned--I'd've liked to read about that. There is a mention of shock absorbers, but only so, jsut a bare hint.

And for whatever reason there is no heavy artillery on this thing. The damage to the enemy would be done via the three wheels, and also by the enormous chains that hang from the front of the enormity, like a flailing slow-moving monster from a 1950's B-movie.
My guess is that this wouldn't do so well in the rain.
Notes:
1. There were very heavy tanks that were being used in combat during WWI when this article appeared, though most seemed to be heavy for heavy's sake, ranging around 15-30 tons. The first "moderen" tank, the Renault FT, weighed in much lighter at 7-8 tons.
