Hello sir Thanks for the video, Contrary to the comment below, the speed control VALVE is adding a pumping loss to the engine by constricting the communication of gas flow between the cylinders,,, and it works, this is great information for some one wondering if directly connected hot/cold cylinders have an advantage to the added unswept volume added by piping for connections and the relation to undersized tubing. thanks again

Very interesting design, most unusual, excellent work.

👍👍👍🌟🌟

What moves the displacer?

Wish we could have seen the working side

i liked 0 rpm that was cool

So... In theory, this could be governed by a ball governor as well.

Why did you start in wrong direction? :) Does not you feel it?

А сколько такой стоит ?

$$??

reality check tom to a significant degree, the rpms of an engine that is doing Work, are Determined by the 'feedback', from the load. consequently, an ability to vary the speed of an un-loaded engine is impressive, NOT AT ALL googletranslate
