Powerless Inertia propulsion craft Printer Friendly Version
Nowaday, The US has the most sophisticated spacecraft. But it hasn't ever developed a transport that can use very little energy.
To overcome the grativational force of Earth, people have to apply a lot of thrust to encounter it to go to space.
But why don't we try to change things around? I believe (although seems impossible) there are two methods to propel the rocket without fuel.
First, scientists can find method to stop a tiny area's gravitational force, then we can just a apply a tiny force to push things up since net force is zero.
Second thing is to stop a tiny area on the Earth to stop rotating suddenly. Due to inertia, the rocket in the specific region will start to move with the Earth rotation speed (A HUGE ONE!).
Personally, i feel that the second is pretty cool.
Reward: Let me be the one who ride on this rocket. Invite me to research in these things.

Modular Public Transport Printer Friendly Version
I live in Johannesburg. It is a city with virtually no form of efficient public transport. It is fairly large and is a problem to get around without a car.
My idea is to implement a modular type of public transportation eg monorail or a surface rail system within a transparent tunnel-like enclosure. This would cover the whole city in concentric tracks with bisecting tracks going out from a single point in the centre. The whole system would be completely automated. The system will automatically select the most efficient route. There will also be an arterial track between cities and towns.
I know this is a fairly futuristic idea but hopefully it will eliminate inconvenience and road car accidents.
Reward: To see it happen one day.

All in One Bag Printer Friendly Version
Take almost any size suit case with wheels and incorporate an accordion style expandable/retractable bag that locks into place in order to accommodate practically anything without having to apply pressure on opening or closing. This means less luggage at the airports and faster exits for your convenience.
Reward: A full line of these items.
