| Electronics That Would Need No Charge 
The key to chargeless electronics is to have super conductors that allow electrons flow freely without collision or inhibition. The current problem is that these super conductors are not congenial to room temperature. If I recall right, the current super conductors can remain super until temperatures of about 168 degrees, while room temperature is about 273 degrees. But the thing is as soon as we can come up with super conducts that work in room temperature, there will be no need to charge up batteries since electrons will not collide, and charge won't be lost through heat. Researchers are still working on this but I am now going to study physics with this being one of my main projects and objectives. It will revolutionize the world and end our energy dependence. Let me know your thoughts pls.Reward: partaking in any projects relating to this.

| Wireless Electricity
I was reading a post by someone back in 2005 and some responses doubting the possibility of electric current flowing say for example from a phone charger to a phone. This is a revolutionary concept that researchers have already started working on and I have done some research on this and it is possible.When two coils have electromagnetic fields with the same resonant frequency (product of induction of the coils and the capacitance plates attached to each end), current can flow from on coil to another or even from one coil to many coils. This is way different than radio ways, and as such reduces fears of people getting electricuted by the current. The current only flows between these mediums with electromagnetic forces around the coils and same frequency. In november 2007, some experiments were carried out by some researchers but they could only achieve electric transfers between devices about 7 feet apart. At least we know that the possiblity exists but we now need to improve on this technology to be able to leave your cell phone at home and still charge it a block away. This would mean a completely wireless world. Please share your thoughts on this and lets improve our world.Reward: partaking in any projects relating to this.

| TV - REMOTE CONTROL
How many of you can't remember where you have left the TV remote control?
A device that you place on the TV and make the remote control beeps when you need to find it could be a nice idea.
(Similar to the wireless phone ‘locate/page button’).Reward: The first remote
