Well, that is a question that was considered long before I was born. Apparently Tesla thought of wireless electricity in 1899 and beyond. In 1921, according to Inside Energy, he posited,
Power can be, and at no distant date will be, transmitted without wires, for all commercial uses, such as the lighting of homes and the driving of aeroplanes. I have discovered the essential principles, and it only remains to develop them commercially. When this is done, you will be able to go anywhere in the world — to the mountain top overlooking your farm, to the arctic, or to the desert — and set up a little equipment that will give you heat to cook with, and light to read by. This equipment will be carried in a satchel not as big as the ordinary suitcase. In years to come wireless lights will be as common on the farms as ordinary electric lights are nowadays in our cities.” (Nikola Tesla, The American Magazine, April 1921)
Wow, what an ingenious prediction! The more I learn about Tesla, the more excited I get. It’s amazing that he considered this over 100 years ago.
