Imagine 3 NEW ways in which invisible computers could change or revolutionize some action or device in the home or at work or any other place in our society (these could require a plug outlet or run on solar power or battery). These should be ideas that do not currently exist, but could exist if technology was developed or used in this new way. Be sure to google your idea to make sure that it doesn't already exist. No credit for great ideas that already exist. I want your ideas to be realistic, since you'll be taking jobs that will be creating our future realities
