Airplane evacuation mechanism Printer Friendly Version
Have you ever asked yourself why there are no parachutes (or not enough for all passangers) in civil airplanes for emergency situations?

Well I have, but the only reason I found is that they are too heavy and take cargo space. Is it plausible to parachute 100 people in case of emergency?
What if there is a mechanism to parachute all passangers in their seats through the back of the plain. The seats should be similar with fighter pilot's seats with an incorporated parachute.
I do not know what is the amount of casualties from plane crashes, but there might be justifications for this mechanism to be implemented in future planes.
Reward: Safe airlines :)

Smart Routing Printer Friendly Version
People drive around all the time. Some people know where they are going, some get lost, and others are slowed by traffic. Some days you get to work with no problems, and other days you run into heavy traffic. There are already systems that tell you how to get to a specific location. There are also some not so familiar systems, that determine the amount of time a light should be green, or red, to help avoid traffic jams (currently used in New York). If we combine the two into one system, I believe we would help avoid traffic jams. In order to do this a person would have to tell a computer where their destination is. This information would go to a main computer containing all the destinations of other cars. Your vehicle would also send out a signal to the main computer telling it where you are at all times. The computer would use formulas to determine what was the best route for every car at that time. This information would be sent back to your vehicle in the form of directions. This computer could also be told where an accident occurred, and then direct traffic around it by sending you new directions. Trial and error would help determine which formulas work best. Different machines could take all the information from previous days and try to come up with new formulas that in theory work better than the ones that were used.
Reward: Good luck!

Dr. Dent (Car Door Protection Shields) Printer Friendly Version
How many dollars are spent annually on door dings? Tons I am sure. My idea would be some sort of instant inflatable shield that can be adhered to the doors on the outside of your car that would hang and cover the doors.
To detour theft of these shields the product would need to somehow be able to lock into your car window or .... It may not need to cover the entire door. Maybe is a long inflatable tube the covers the horizontal length of the door and adheres with a magnet.
Reward: 1 free set of the product. Would be great to help if at all possible
