I wouldn’t call it “harvesting” if you have operate power transmitters on each floor of the house. “Energy harvesting” usually means you are using something that is already present in the environment.
“each floor would have one or two RF (radio frequency) power transmitters to powe r up all switches inside the house.”


If people start choosing their flights based on aircraft type, it seems like the airline could just list all flights as the “good” aircraft and then automatically change it to the “bad” aircraft close to the departure date.
