The contest will be an obstacle course involving a series of challenges including operating a train engine, paddling through whitewater rapids, scaling the side of a mountain, crossing a gorge using a rope, and racing a horse-drawn wagon to the finish line.
With Jim Dale, Karen Valentine, Don Knotts, Jack Elam. This saga of the old west involves twin brothers who compete for possession of a rickety cow town founded by their father while a crooked Mayor tries to put an end to the competitors so he can inherit the town himself.

The principle of employing heated air as a motive power is very old. The history of the Heated Air Engine dates as far back as the year 1699, when AMONTONS(France, 1699) invented his atmospheric fire-mill, an air engine where heat was transformed in mechanical power. Amontons heated and cooled the same air over and over, in a closed-cycle engine, h...
The first class is after the similitude of the Glazebrook, 1797, and Lilley, 1819. Ericsson patented improvements in air-engines in 1851, 1855, 1856, 1858, and 1860. The following affords an example of one of his engines. ERICSSON, specification patent of July 31, 1855, describes the invention substantially as follows (the illustration is reduced, ...
The second class is as the principle of the English patents of Glazebrook, 1797; and Parkinson and Crosley, 1827. LAUBEREAU, April 10, 1849; patented in England, 1847. This engine is the first which embodies the peculiar features of a furnace in the air-heating chamber, and a hollow plunger of corresponding form. The air is alternately dilated and ...
The third class is on the principle of the Stirling engine, described in a preceding portion of this article. PETERS, November 18, 1862. The air is heated in two vessels connected with two opposite ends of the working-cylinder, and the invention consists in so operating the two plungers that the one in either heating-vessel is stationary in its upp...
The fourth class includes those which use steam to lubricate the parts; an example will be given, but it is not to be inferred that it is confined to one. The immense expenditure of grease has induced the use, in many or perhaps most of the air-engines, of moistened air as suggested by Glazebrook 1797, Oliver Evans about the same time, and by Benne...
Of the fifth class is the patent of SHEARER, September 3, 1861; in which two cylinders are used with two pistons, the faces of which are in contact with water, which is caused to pulsate by the action of bodies of air. The air is acted upon alternately by heating and refrigerating means. KRITZER, July 29, 1862. This invention also belongs to the fi...

One major drawback of the steam engine was the dangerous boiler which contained hot, high-pressure water and steam. It had to be diligently maintained to remain safe. In contrast, the hot air engine used an enclosed volume of air to bounce back and forth from a hot side to a cold side.
Energy flows from the hot reservoir to the cold reservoir while doing work. Actual heat engines have many different designs. Examples include internal combustion engines, such as those used in most cars today, and external combustion engines, such as the steam engines used in old steam-engine trains.

A steam engine needs a steam boiler -- and a simple teapot will not do. Engine builders before James Watt had worked with both high and low pressure steam. For high pressure, Thomas Savery tried to build small boilers of soldered copper.
