Fast Transport of Packages Printer Friendly Version
If anyone has ever played the PC game Grim Fandango, there is a machine which sends messages through the DOD building. I think we could expand that idea to have a virtual network of package delivery systems. You would simply put the package into the containter, close the lid and enter where you want the package to go. This would release the package into a very large tube which would push the package to its destination via vacuum. There would be sensors that detect where the package is going, so that when it gets very close (and there is no package between it and the destination, a cushion is released, stopping the package, which is then lifted using a rising platform to where the person at the other destination can get it. The cushion would then be detracted to let other packages flow. The package would be tracked using the FedEx like system (perhaps using GPS technology?) which tracks its packages. The first system would connect major centres, which then would have subsystems to join the major cities in those general areas. Finally a third subsystem might be used to connect the smaller cites in the area, although at this point the current system (e.g. UPS coming to your door using their brown vans) would suffice. So the package would simply go around the globe to major centres, and then put into a different system of package tubes which serves the local area, and so on until it reaches its destination.
Realistically, this is a very long term idea, but in the nearer future it would make sense to connect the hubs that all the package companies fly to with these tubes.
Reward: Less pollution in the air from jets flying packages is ... priceless.

Hi Speed Rail System Printer Friendly Version
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.

Eliminate Highjacking Printer Friendly Version
With last year's attacks on the people of freedom and common sense, hopefully security will be more closely watched, but if dan or mary decide to have a bad day at work, we don't have to worry about a simple slip up because everybody that gets on the plane has no access to the cockpit during take-off and landing and if someone decided to cause a problem then the entire passenger section will be put to sleep. - End of problem!!!
I think it's a safe way.
Reward: That everybody stop the foolishness and needless greed and the faded teachings that were passed down from people that not more than 200 to 300 years ago cut heads off of people because of different ways of life.
