Running on Sound

Your architect designs a house which runs on sound instead of fossil fuels or electricity. So you talk and the lights come on. You just set up which lights you want on and which are off. You clap and the blender works so you can make a smoothie. You ring a bell and the water comes on for washing the dishes. At night when it's all quiet only your clocks and other essentials are running from the sound of your breathing. When no one is home to make sound the refrigerator, clocks and such run on wind power which it generates from a windmill outside.

Where do you go to have an argument if you ever get into a yelling match with someone? Having an argument at home is a really, really, bad idea.
