| Battery Powered Pocket Cigarette Lighter 
This lighter would heat with a couple double AA batteries exactly like an auto mobile electrical jack lighter that we all plug into our cell phones into nowadays to charge them. The hot spot would be contained within the center of coils so that the heat would disappear quickly, come with its own lid and only be hot when you pull the trigger to heat the element in the center. You would always know whose lighter it is since you would never change anything but the batteries and it could be personalized in any way so that you don't accidentially grab a lighter that's dead (or some one else's lighter), and the battery meter could easily be placed on the outside so that you can tell when it is a good lighter that will light.Reward: One in all designs!

| Digital Film Roll
How about a Digital Film Roll cartridge for a standard manual SLR Camera that can replace your conventional 35mm film roll... The digital cartridge could have parts which would fool the manual SLR to believe that the roll is real... i.e., wind the roll in place after every exposure, unwind etc. The cartridge would consist of a battery unit, storage space, exposure transfer screen/pad, roll advance sensor. The battery and storage is shaped like a standard film roll atttached to a screen, which registers the exposure through manual/normal operation of the camera, and the forward movement sensor fools the camera that the picture has been taken. The battery and storage unit would have necessary sockets for transferring photographs to the computer. Such an equipment could save development and processing cost of photographs.Reward: free of cost!

| Transport Light by Optic Fiber - Save Energy
My idea is to supply light using optic fiber instead of the electric wires to save the energy. As we all know that when electricity travels through wires, it loses its power (potential difference). Hence we lose lots of energy when electricity travels from the power station to our home.My idea is very simple... here are the steps:
1) Generate laser rays (or other high intensity rays) at the power station and supply it to home via fiber optic. Light loss will be less than 1% in fiber optic.
2) At home, change the laser ray light to normal light using a device.
3) Use any opaque glass material to scatter the light in all directions.This is my basic idea. There may be theoretical loop holes, but can be corrected.Reward: :)
