Larry Boreham's....Quartzite Trip

This engine has been reported to have been run at shows for the last 7 years. It is constructed from 2 spray cans and 1 inch copper tubing for power cylinders.	The frame and beams are made of 1/2" EMT thinwall. The phase angle between cylinders is approx. 65 degrees and runs very smoothly. It uses 2 alcohol burners for heat.
Here is a Stirling water pump fired on wood!	Stove Top Stirling Fan is an 18inch unit with a hardwood piston with a leather piston ring.
Here is a closeup of the crankshaft and connecting rods to the power piston and the displacer piston.	This is a Low Temperature Difference Stirling engine. The sunshine heats the upper plate which is the (warm side) heat exchanger.
The LTD can run off sunshine. It has ice under the lower heat exchanger and runs on the temperature difference. Notice the unique linkage that connects the crankshaft, the displacer, and diaphram.	Here is a closeup view of the linkage. Notice that this uses a diaphram rather than a piston for power!
