Some new technology id like to see invented is flying fans. Fans are good but sometimes they only reach a certain spot. Id like to fans move back and forth from the room. Not the fans that turn but fans that literally move around the roof. You can install it and turn it on and it moves around. Kind of like a romba the moving vacuum. I would want that as a fan that you install on the roof so you can get air all around the room evenly. Sometimes the fan takes a while to cool down the room as well so the fan could have like a cooling mode so instead of the fan just letting out air it can let out cold air sort of like an AC. But Over all Id love to have a fan that moves around so Im able to get air evenly around the room without issue or without it only hitting one spot of the room or taking forever to cool down.
