1. E-Notepad a small waterproof touchscreen device that can take pictures and handwritten notes. Syncs to the cloud so you can access anywhere else.
2. Printed Furniture Store Industrial sized 3D printer that specializes in printing furniture. Endless customizations and cheaper than IKEA!
3. Glow-in-the-Dark Sports Fields Lines, balls and jerseys are all glow-in-the-dark so you could play without stadium lights. Potentially less expensive.
4. Worldwide Tag everyone signs up on a site with their device ID. A random person is "It". That person has to track down any other player in the game. Security screening necessary for obvious reasons (e.g. stalkers). Another option is to play this with an online group of friends.
5. Act Something Charades online. Get a random word or phrase. Shoot a clip of yourself on Instagram Video/Vine/Generic Social Video Platform. Send it over to your friend to guess.
6. Rent-a-Driveway Have an empty parking spot? Rent it out for a set amount of time. Essentially AirBnB for parking.
7. Inheritance Cap To fix income inequality (an increasingly worsening problem), the amount of assets you can pass on should be limited to an average person's lifetime salary.
8. Habit reformer Helps analyze your habit loop (i.e. keeps results of various rewards and tracks your cues) and records the number of days you've successfully stuck to a new habit
9. Real-Time Fact Checker by accessing Watson via the web and using speech-to-text, instantly fact check someone's claim. The cure to the increasing number of people that are good at bullshitting
10. Who's Free Right Now sends a message to nearby friends that appear to be stationary and ask them if they want to hang out
