Beautiful external combustion kraftwagen model

Hammacher Schlemmer is certainly fond of Stirling engines. Well, who can blame them? The latest addition to their catalog is this Stirling engine powered vehicle. Made of machine-tooled brass, stainless steel, and aluminum, there is no denying that it is a beauty of a working model, if a rather pricey one.

From the product description:

An alcohol burner in the rear heats a cylinder; a quick twist of its brass flywheel sets the engine's displacement and working pistons into motion up to 2,000 rpm. The resulting expansion and contraction of heated and cooled air inside the engine operates a rocker arm, connecting rod, cam, and crankshaft, which spin four flywheels to drive its two 3 1/2" diameter rubber-bound wheels. A third wheel in front can be manually turned 360 degrees, allowing the car to perform autonomous circles while it putters efficiently.

Here is where you can check out this External Combustion Kraftwagen.
