An engine powered by microwaves

[bugler]

some months ago I met an aeronautical engineer. He told me he had many invetions and even made a prototype of an engine fuelled by microwaves.

Imagine an ordinary gas engine where the top of the piston instead of being flast forms a half sphere (the lower half) and the top of the cilinder is the other half of the sphere (the uuper half). So when the piston is up the the half spheres make a complete sphere.

In this sphere microwaves are entered and as they are in a sphere they resonate and heats the air to 3000ºC. This hot air expand same as gasoline when combustion starts.

So there is no fuel and the only input required are 2000W microwave source.

He says that the prototype exploded due to too much heat being created.

What do you think?

(sorry for the terrible explanation but 3d descriptions in englihs are quite difficult for a foreigner)

seems interesting.

Probably would need a different material for combustion chamber for it to
work ceramic, plastic, etc.

You could not do it with metal... all you would get is enourmous uncrontrolled arcing. Then there is the issue of mounting and controlling a suitable waveguide .. not the easiest problem to solve.

That said, 2Kw of microwave energy is a small generator and unless multiple cylinders were being 'fired' at the same time then one would surfice.

Other issues are that has higher revs, the mark time would be very short, so possibly a higher powered pulsing microwave .. then it all gets more complicated.

I doubt this is a runner. That level of microwave energery is seriously bad for you if it leaked !

I did read someting simular at the neigbours, here is also a website about it:
