Monorail transit on the Interstate Printer Friendly Version
Build rapid electromagnetic monorail system for passengers and light commercial shipping, using the median space between the lanes. Of course, overpass supports would have to be re-configured and the system would have to be protected by some type of barrier or fence. This project would create thousands of jobs and, when completed, would offer an efficient, clean means of mass transport.

Automatic Toothbrush Printer Friendly Version
I did a science fair project on this one... A tooth brush that had tooth paste in the handle which would dispense through a tube into the bristles. Of course to market such a thing it would either need to be disposable or refillable. I had a proto-type at the fair and everyone liked it. What do you guys think?
Reward: Just the satisfaction that I had a good idea.

Air Hockey Type Skate Boarding Printer Friendly Version
If you take the wheels off of a skate board step onto it then glide on a smooth surface with air holes pushing up strong currents of air you can glide for hundreds of feet with just a slight push of your foot. We could make an indoor or outdoor Air Hockey Type Skate Board Park where we could use any smooth object to safely project ourselves across the smooth surface and use the same construction of an average skate park only this would be more fun, you could go faster and further, and the surface would cause less damage to limbs since it would not be concrete on the surface. A totally new sport to replace one that is getting quit boring thses days. You could make any type of board any size and length or shape as long as it was smooth on the bottom. You could even make boards to glide on your knees or elbows alone or shoes that would move you across the surface. A very easy park to make. A very safe way to board. And tons more fun!
Reward: Credit
