What's to stop it all from freezing again afterwards?

I mean, you run this microwave, heat it all up, melt more of it, than it all freezes as a sheet of ice immediately afterwards (cuz it'd be a fairly thin layer). So now we have skating rinks instead of salt and dirt/sand.

I think it's not gonna work in the real world.

I mean there's supposed to be drains and everything, but more than likely they're be covered with snow, so the water will have no where to go and just freeze.

Am I missing something? also yes I didn't read TFA.
