Self Controlled Car Speed Restrictor Printer Friendly Version
The "NO-SPEEDY CD" device replaces your regular in-car CD player. But the "NO-SPEEDY CD" player is driven by a series of belts, chains and sprockets from the front wheels of your vehicle.
Now go and buy your favourite CDs in various speed formats, and pop in the appropriate format dependant on the speed restrictions youre driving within.
Hey presto, youre in a built up area and you've got your 30mph version of Steps playing. If you start to go too fast, they sound dreadful and you slow down to a more suitable speed.
Reward: A cheese and pickle sandwich. .... and some crisps.

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.

Rooftop Monorails Printer Friendly Version
In the downtown areas in major cities heavy traffic is the big issue, since it is waste of resource and time and polluting the air. Therefore the government tries to reduce the heavy traffic and solve many problems. However, we can't build new road or subway since we have no space on the ground or under the ground. So I thought it would be nice to make a road in the rooftop by connecting the rooftop of buildings with road.
Since it is much more dangerous than the road on the ground, there should be many safety net and only government granted monorails should be allowed. Office workers can get off at the rooftop. This will solve heavy traffic and also relieve the dependence of subway. People feel stressed in early morning because of crowded atmosphere during rush hour. This makes people uncomfortable from the beginning of the day so if people using subway decreases people can start the day with joy and this will increase the efficiency of workers so corporations can also benefit from this.
