1. JOHN: Well, I decided to make a dishwasher that uses carbon dioxide.
2. PROFESSOR: Sounds like a brilliant idea! Your system will totally do away with the need for strong detergents. So what happens once the dishes are clean?
3. PROFESSOR: In place of water and detergent? How will you manage that?
4. JOHN: Well, to allow them to dry, the liquid carbon dioxide and the waste materials all go to an area called the holding chamber. That’s where the liquid is depressurized and so it reverts to a gas. Then the oil and grease are separated out and sent to the waste system.
5. JOHN: The idea is to pressurize the carbon dioxide so that it becomes a liquid. The fluid is then released into the dishwasher where it cleans the dishes all by itself
