Live-Cam on Aeroplanes Printer Friendly Version
When you're travelling by plane, there's often something spectacular going on outside (and I'm not talking about burning engines - rather something like sunsets, cloud patterns or fantastic sights on the ground). Unfortunately, you can rarely see these things, as you're usually sitting on the wrong side of the plane. So why don't they use a mini camera to broadcast those events to the main screen so everyone can see? It would definitely be a great service appreciated by most passengers.
Reward: Free plane ticket or bonus miles.

Cheaper Elevators Printer Friendly Version
Elevators (lifts in England) are expensive to install and require top room for the lifting gear. Would it not be possible to build elevators on Archimedes Screw principles - a rotating shaft moving small, single person platforms? No cables or wires to break. Can be used for two storey building.
Reward: Recognition for the idea.

Efficient Take Off and Landing for Airplanes Printer Friendly Version
The start of an airplane consumes a lot of energy and is very stressful to the tires. An airplane could be started (and landed) sitting on a magnetic driven carrier which is accelerated by a linear motor installed in the runway. This method will save fuel, tires and reduces noise at airfields dramatically.
Reward: A cleaner air for my planet.
