Technical
Mark Twain riverboat burns diesel fuel to heat its boiler, continuously heating water into steam, which is then routed to two pistons that turn the paddlewheel. Spent exhaust is then routed back to the boiler.
The riverboat is guided through the Rivers of America via an I-beam track, which is hidden under the green and brown dyed river water.
The boat draws only 18 inches (460 mm) of water, for the river is relatively shallow. At its deepest point it is no more than 8 feet near the switch at Fowler's Harbor, where it resides when not in operation.
The boat uses clean, fresh water from a tank on board to prevent contaminants from the water in the Rivers of America from fouling the boiler.

Famous quotes containing the word technical:
“A technical objection is the first refuge of a scoundrel.”
—Heywood Broun (1888–1939)
“Where there is the necessary technical skill to move mountains, there is no need for the faith that moves mountains.”
—Eric Hoffer (1902–1983)
“Woman is the future of man. That means that the world which was once formed in man’s image will now be transformed to the image of woman. The more technical and mechanical, cold and metallic it becomes, the more it will need the kind of warmth that only the woman can give it. If we want to save the world, we must adapt to the woman, let ourselves be led by the woman, let ourselves be penetrated by the Ewigweiblich, the eternally feminine!”
—Milan Kundera (b. 1929)
