Last run of the DIY stirling Engine before it goes to it's new home where it will be shown at stationary engine rally.
I've made a few changes and I just wanted to see the stirling engine work before it goes to it's new home
To see other videos of the Mk3 stirling engine:

I've added a car type radiator so it can be run without a water supply. This is worked by the thermosyphon effect so no pump is not needed. There is also a generator so I can charge some batteries of power something and this gives out about 50VDC. I don't know what the max power was
because I simply ran out of time (probably 180w or so not amazing)
This engine has evolved somewhat since I first designed / built it. I've summarised what I think are the good points and bad points below,
Good points
Design is simple and reliable
Heat exchanger design worked
Concrete flywheel very easy to make and worked great
Bad points
Temperature difference between cold / hot not great
Piston arrangement very heavy and internal guides problematic
Excessive temperature reaching hot piston seal (but it does work!)
Much bigger than it needs to be
So there you go, it's been great fun and I've learnt tons of stuff about stirling engine key parameters.
I've got a new design of stirling engine that I've been planning in the background and hopefully this time I might get it right! Only time will tell!
Join me in a few weeks and I'll explain all : )
Please help me out with any suggestions you have
Cheers
