IN THE HOME OF THE FUTURE, appliances will be linked like hardware on a computer. Just like a new wireless keyboard, printer or touch screen monitor, you need only place the new appliance into service and it will communicate on a machine to machine basis (M2M), providing useful data for energy and performance optimization. But electronic communication is one part of the equation. There is also the concept of “Thermal Communication”.
The household appliances in our “Celestia Home of the Future” will prompt, "Do you really want to start the washing machine now, while the shower is on and the dishwasher is running? Please allow me [the smart M2M system] to start this for you later, when energy and water consumption can be optimized, saving 1.3 kWh of peak load energy consumption." This simple logic and communication between machines, homes and communities will defer infrastructure costs for building of power plants that could be averted.
