| Tongue writer 
I had this idea at a halloween party, but there might also be other, more serious applications.What if you could poke out your tongue at someone and display a certain design/words, and the next time your tongue comes out of your mouth, there's something completely different written on it? In theory, there are many (more or less convenient) options to achieve this, like putting a (mini)printer into your mouth, or hiding a tiny projector in your nose to project the image on your tongue once you stick it out.Probably the easiest way would be to hide small, pre-written sheets in your mouth (maybe just "yes" and "no") and find a way to rotate them. Or just a small, two-sided plate that you can easily flip with your tongue.Reward: I want a sample so I can joke around with it at the next party

| Hi Speed Rail System
The U.S. presently has thousands of miles of Interstate Highway right-of-ways. Why not build a hi-speed elevated rail system that crosses the U.S. There is usually plenty of room in the medians. If the system is elevated there would be no need for crossing etc. The system could be built with ready-made concrete and steel components that would be easy to construct. These trains could have speeds in excess of 120 MPH. It could also have cars that would transport the family auto. In addition, it could be a public works project that would employ thousands of people similiar to the TVA and the building of the Hoover Dam.Reward: I would like to travel across the country on such a train.

| Nerf Cars
If all cars were made of spongy, "nerf-like" material, and perhaps had roller-ball wheels, and definitely made to run a bit slower on freeways - we could save thousands of lives each year - and have great fun at the same time. Imagine how many bazillions could be saved thru reduced (or eliminated!) insurance needs, and cheaper fuel costs... and repairs would be rare and cheap, too. We don't really need to race to work at 80 or even 55 mph. Imagine how much more fun it would be to drive places. If someone hit your car you would probably laugh and wave! If I had to drive to work every day, I'd like it to be in a nerf car. It could change the world.Reward: I'd like the chance to work on this project... or maybe just a bright red nerf car of my own.
