Is it possible to charge a portable device such as a cell phone or iPod, Wirelessly? say for example I'm using my cell phone, But its battery is almost dead. and I'm not in a situation that you can plug it in wired. Now... Imagine i can have my charger plugged in but instead of being connected with wires to my cell phone. instead it would give it power over a wireless connection? if this technology is not available now... could it be available in the future? |

There are some devices that allow completely wireless charging, for example, this device uses everything in the 2.4GHz spectrum in order to charge a battery. http://www.bbgeeks.com/blackberry-accessories/charge-your-blackberry-battery-using-wi-fi-signal-884283/ the company is currently working on making a battery with the technology built in. While a wifi access point may only give out 28-1000mw of power, it is hard to go anywhere where the 2.4GHz band isn't flooded with signals from many. sources While technology like this and also those random magnetic power pads do not provide much power, if a company was to use many sources such as both radio wave charging and also solar power and any other technology that doesn't get in the way, then people will be able to have mobile devices that will go much longer between actual wired charge cycles. |

Well, there are testings that you can pick the Radio and wifi frequencies from the air for free and convert that to electricity, although it is currently not a lot, it may be possibly (but when Heavy amounts of electricity is in the air, it may cause health problems). http://gizmodo.com/5370418/yes-there-is-such-a-thing-as-free-energy http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/ |

My Related Question > The Idea of Transmitting Power Over the Air is at least 100 years old, but is it Safe? More is merrier for wireless power supply

Yep, it is possible. There have been some techies pushing witricity as a means of remotely charging anything that is rechargeable. |

Simple answer: Yes it is possible, but not long range. what happens if you get twice the distance away from the charger you receiver 1/4 the power three times away you get 1/9 the power, most the wireless chargers that are worth looking at you need the device to be on top of the charger. |

I'm just 14 years old and made what may be a way to send electricity however I haven't revealed it to the public yet. How it works: 1 copper wire (without the plastic around it and the second copper wire) both wires were made into a coil mostly from the center of the copper wire. One of the coiled wires were attached to for example: a chargable 9 volt battery ( specifically the connectors on top of the battery) and same thing was done was connected to the same part of a non chargable 9 volt battery. The non chargargable battery is the power source of the chargable 9 volt battery. One wirelessly detects a power source nearby and recieves the needed electricity. Its like connecting a laptop to your router. I tested this concept and it works. Try my idea AND HOOK IT PROPERLY IN ORDER TO GUARRANTY IF IT WON'T WORK. email me with questions at owarders@gmail.com and I will be happy to answer any problems that occur. Thanks and have a great day. |

I'm just 14 years old and created a way to wirelessly charge your devices. It involves copper wires (without the plastic outing aroung it and the second wire thats with it). You coil the 2 wires and simply use it to lets say for example, a chargable 9 volt battery. you probably have one that needs charging but dont have a proper charger for it, but needs it to be charged. its preety simple process here. you connect one end of the coiled wire to the + sign side of thwe 9 volt battery and the other side to the - side part of the chargable voly battery. you then do the same thingt to another battery, the non chargable 9 volty battery. this battery is the power source for the chargable battery. The chargable battery already knows that it doesnt have enough electricity to power something, and with the copper wire being coiled and attached to it, gives it the ability to check around for any electricity force around i, and automaticly connects to it and starts recieving electricity right away. it works, i have tested it (with the 2 different batteries mwntioned above) and it seems to work as i said. I havent revealed this idea to any company but it seems like it would be an acceptable idea. i mentioned it to my high school science teacher (im in 10th grade right now), demoed it to him, and he said i should tell come big battery company (duracell, energizer, apple, etc.), and i will later today. TO MAKE SURE THIS WORKS AS MENTIONED, HOOK THE WIRES PROPERLY TO THE BATTERIES. If you have any questions, concerns, or problems, please be sure to email me at owarders@gmail.com, and i will be happy to assist you. thanks in advance and have a great day. |
