1. Phones, should have an "emergency mode" feature. Your phone turns off as soon as your battery reduces to 15 minutes of remaining talk time. In an emergency, even though your phone is dead you know you have the backup up 15 minutes.
2. I would be curious to see soccer do something similar, to what cricket did with the Indian Premier League, to increase the moments of excitement in a shorter game. I would reduce the number of players on each side, make the goal slightly bigger, reduce the game length to 60 minutes, and not allow strikers to pass the midfield line (need to stay on the attacking side). Needs more, but think this would be a good start to a more interesting American league that caters to those who want to see more goals and action.
3. On a road trip, where your group has a several cars, it would be great if there were ways to enhance the group experience. Here are a couple ideas:
3A. Have the ability to have all cars be listening to the same music, with cars taking turns being the main DJ.
3B. On the same channel as the music, cars using a radio channel, to be able to easily radio between the cars.
3C. One of your GPS views, shows where all the cars are.
4A. China is building the world's largest tower in 90 days. I would hate to be the person who needs to check whether its safe to go into that building?
4B. Every few years, someone decides to build the world's largest tower. Why doesn't someone build a tower where in the future, they can continue to build right on top it anytime someone decides to build a taller tower?
5. After watching Lebron James amazing performance in the NBA Finals, I have decided I really need to read those Hunger Game books. Also, the NBA has enough material for all of their advertisements for "Reading is fundamental" next year.
