Can I use an electric arc to superheat air an expansion chamber to create thrust? Answered

I have an idea about harnessing the electric arc from my makeshift Jacob's ladder to super-heat air at a very rapid pace within an expansion chamber of a ramjet rocket without using any combustable gasses. Can I get any suggestions for more effective forms of thermal expansion?


great idea i am working on this already

Thrust is generated mainly by mass transfer Heat alone is just heat. Sounds like a very energy intensive method and somewhat wasteful

In principle yes BUT There is a heat transfer issue here - Air is a poor conductor of heat so getting the arc - a relatively small area - to heat a relatively large amount of air will not be easy.

This is how stirling engines work except the heat and cool using a large area/mass
