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.

Transport produced electricity Printer Friendly Version
Everyone walks and/or drives. Technology exists now to produce electric charge when pressure is applied - looks like sandwiched sheets.
Why not put huge expanses of these sheets under the main thoroughfares, stations, highways, etc...? Then all this random human movement starts producing electricity for our cities. Store it properly in something better than batteries.

Electricity through the air Printer Friendly Version
Be able to power your lamps and other electrical things without a power cord. One main machine sends electricity harmlessly through the air, and whenever you turn something on that has a receiver, it pulls the electricity from the air. You never have to deal with cords again!
