| Spherical 3-D Mercury Switch 
A switch that can give any device an instant (automatic) equilibrium. Every spot inside the sphere has a different touch point much like the old mercury switches that regulated heating systems, but this one has thousands instead of two contact points making and giving it a total 3 dimensional capability. If it were in the head of a robot the robot would then know exactly where it was. It would know left, right, tipping, forwards, backwards, and upside down. All directions. Then it could constantly adjust itself and compensate to keep up right and mobile. This switch could be used in heavy equipment or in other technologies. Almost any device or equipment that needed to stay stable and up right would have that exact ability with this switch. It could be used in large or small toys like a moving flight simulator you see at the mall or a gyroscope.Reward: Credit

| National Database of Public Bathrooms
I know I am not alone in my disgust for the bathrooms of many businesses. I have pulled into gas stations with new pumps, the latest architecture, and so forth, only to find the dirtiest, nastiest bathrooms. I think a national database detailing bathroom cleanliness of particular establishments, as well as the publishing of those results in newspapers, etc.... would lead to some changes.The database should include detailed locations so people can specifically avoid such places. After all, what station wants to be listed as "Avoid at all costs!"?Someone needs to create a website that allows people to enter the name and location of a place and then select from a list regarding the cleanliness. For example: Superior, Excellent, Good, Fair, Poor, Unacceptable, White Trash, Living Filth, Utter Squalor, 7th Level of Hell...OK, I got carried away, but you get the idea.Reward: Just knowing someone is doing it.
