Shouldn't we have faster microwaves by now giving out a few kW?* They

High power microwaves (1MW) are used in industry in for example ore
extraction/rock pulverizing.
1MW into a cup of water is not pretty, explodes the water contents and
breaks the cup.

I don't need a MW, but the usual 600W to 900W in domestic ovens is
pitiful.* What's wrong with 2kW?

too expensive

1200 watt consumer microwaves are widely available. Check your
Walmart or whatever you have.

1200W isn't much more than the 900W most are.
Let me see: 900 / 1200 = .75.
So a 900 Watt microwave has 3/4 of the power of
a 1200 Watt microwave. Or looking at it the other
way a 1200 Watt microwave has 1/3 more power than
a 900 Watt microwave. That doesn't sound like a
negligible difference. I know when I accidentally
replaced my 1200 Watt unit with an 1100 Watt unit
I noticed the difference. (I didn't look closely
enough when I grabbed it off of the shelf.)
