Friction
The surfaces against which each piston slides has been changed to brass. This is done to reduce the friction between moving parts.
Also, the length of the bushing through which the displacer shaft slides has been shortened to further reduce the friction.
High quality bearings will be used for the flywheel axle to rotate around so that there is less resistance to the movement of the pistons.
Pressurised Closed System
A presta valve has been included in system to allow the air to be pressurised. If the system is air-tight enough this will help to improve the output power.
