: Delaney Power Extractor Engine

Hi All,

I came across this website powerxtractor.com through a friend of mine
and this new engine sounds pretty impressive, but I don't know enough
myself. What do you all think, is it really good as my friend said?

Thanks in advance for help

Somehow the thing seems far more complicated than a radial aircraft engine, which principle it appears to mimic. Ever seen a wobble-cam crankshaft? How the devil do you stabilize it ?

This kind of stuff has been around for 100 years and it still isn't practical and it still doesn't work. http://www.bourke-engine.com/
