You-powered Thermostat by Katherine L.

The innovation in my article was Blow, a thermostat that you can control with your lungs. If you think that the room feels too chilly, you blow on the thermostat with your mouth open, as if you were warming your hands in the winter. If you think that the room is too hot, you blow with a pursed mouth, as if you were cooling a bowl of soup, to turn on the air-conditioning. I think that Blow will have a mass appeal. Almost everybody has a thermostat, and it's so easy to use. However, I think that Blow will be a fad. When it first comes out, everyone will want it because it's the newest technology. After a while, people will realize that a normal thermostat is just as easy to use, and probably costs less, so I think that its popularity will fade away. I would not buy this product. I think that it will probably be expensive, and I can do just as much with a normal thermostat.
