Heavy diesel engines were dominated by the rest of the world in the 50s. Military aviation has no need for efficiency nor actual maintenance cost targets and thus, you have way more manufacturers of military than comertial engines.
My point is more that these domains seem civilizationally Hard. Western companies are very far in the effort/results curve. Will the Chinese get there? I guess at some point, though I doubt there is any incentive for the ICE motors in particular.
China "cheated" with EVs. They never managed to make a combustion engine that could hold a candle against western ones in terms of efficiency and reliability. Electric motors are waaay simpler.
I doubt that the same will happen in commertial aircraft engines. If China catches up it will be through industrial spionage or very slow grinding, that will take many years.
If I were you, I'd try to forget it as soon as I can, becouse it's wrong. 2.4 GHz is not in the water absortion band (I'd show you a nice graph, but I can't find one that goes to such low frequencies), a microwave would work as nicely in 1 GHz or 5 GHz, what matters is the H-O bonds, that are esentially electric dipoles and are excited when high-ish frequency and power hits them. You probably have noticed that fat heats much faster than wattr in the microwave oven, that is becouse is full of OH bonds, just as the GP is full of shit[1].
This is one of those moments when I wonder if most of the things I have learned in HN are bullshit, I'm usually struck with awe at the sapience of the HN hivemind too, but in times like this...
