Right-angled Low Temperature Stirling Engine

This is a variation on the conventional method of displacer and piston connection. In the Low Temperature Differential (LTD) Stirling engine the piston and displacer are normally connected at opposite ends if the main axle.

In this engine I have connected them on the same pivot and aligned the piston at 90° to the displacer. The displacer is thus kept the required 90° phase angle ahead of the piston.

The expanding and contracting air inside the main bottom chamber is ported up the inside of the piston pillar, out through a flexible rubber hose and into the end of the glass cylinder.

The black disc under the engine is solid plastic. It was left in the sun for a while, until it was good and warm, then the engine was put on it and started. The engine will run on hand heat but using the black heat disc is more convenient when filming.

Superb

is a variant on this design possible in which the main chamber is on the side rather than on the bottom? That way the chamber can be heated directly by the sun. Cooling fins may also be needed.

Beautiful sterling!

@brooke959 make it your self. you just need to calculate the air density at each temp. then make the smaller piston the same fraction of the bigger piston vs the fraction of density

[brooke959]

where can you get this exact design from

[laurasIs2c]

It looks terrific, can you explain what is your idea for applying the process to our lives?

You could educate many a young scientist.
