Benedikt and Hunter and I spent some time with two minutes of Energy Theater video today, in which the E2 people did ET for a refrigerator. This ET session came after about ten hours of discussion spread over three days, and was pretty much the conclusion of their study of refrigerators. The video below is of their first walk-through.
Three objects in the scenario are denoted with string loops: the food, the coolant, and the electrical outlet. The surrounding environment (say, the kitchen) is understood to be outside the loops. Thermal energy people fan themselves, people with their arms circled over their heads are "phase energy" (which is the kind of energy that gases have more of than liquids), and people with twinkle hands are electrical energy. The coolant that is represented here is not all of the coolant at once; instead, it is a packet of coolant that moves around the coolant-circuit as the action proceeds.
We are still figuring out the significance of what all they do. Why do some of the phase-energy people walk down the stairs when the electrical-energy people enter the coolant (i.e., when the coolant-packet is in the condenser)? Is it significant that the thermal-energy people that go out into the room when the coolant is in the condenser are the same people that were originally in the food? Did they skip the evaporator at the end? Plus there is a lot of lovely interactional stuff we barely touched on, like: When are people taking direction from Matt and when are they acting independently? Which people know what's going on? When do people drop their arms? When does Matt consult the white board? What is Lisa's contribution? What is Hunter's role?
This is all about stuff that happens during this short episode, which is natural for me since that's all I've seen. Hunter and Benedikt have more of a sense of the conceptual development that happened over days, and have posted thoughts about that on their own blogs.
