Power your laptop/mobile device wirelessly- (Wireless Power Induction)

^ it would be amazing if your cell had it built in. sitting in your room with it in your pocket and its charging.

there are even a few cordless phones that use inductive tech to recharge the handsets, great way to make a device waterproof

I'm now thinking of all the electromagnetic field in such a room, and I don't feel very comfortable.

The biggest problem I see is getting a frequency from the FCC. Microwaves, cell phones, routers, portable phones, all these things work on certain frequencies like 2.4ghz or 5.4ghz. There may be better frequencies they'll work on but it's illegal to create anything that works outside that because those frequencies have been specially allocated for these types of devices by the FCC and they monitor that very closely. So if a company did succeed with this technology, they would have to apply to get their own frequency for the devices or work on the same frequency as some of the other stuff causing interference in certain applications. That's why portable phones, microwaves and routers don't play nicely together when they're all running on the same frequency.

Hello All, Kind of new to the forums, but this caught my interest so I thought I would post.

While it does seem to have some potential in some environments, overall, I don't forsee this being something that I would want because of it's gross inefficiency.

hardly anyone has heard of this guy, yet he was an astounding prolific inventor, probably the closest thing this world has seen to Da Vinci since, erm, Da Vinci

As for Mr. Tesla, there was a great documentary about him on the History channel. I am a forever Electrical Engineering student so I was telling my two younger brothers about him years ago. Thomas Edison was a thief. Kids are taught that Edison created modern electricity when that isn't the case. Edison even electricuted an elephant and other animals to discredit AC in 1903 in a park in New York.

For all of his good things he was slightly psychotic too, which most geniuses turn out to be. Must be why I have Delusions of Grandeur

Anyway sorry for the history lesson

It's interesting to see everyone's opinion on this topic and mostly negative. I don't expect this power solution to be applied to regular desktop PC's or as a 'constant' power source. I created this topic with interest of this being a means of simply 'recharging' your mobile device...as opposed to 'supplying regular and reliable constant power'.

I am working on mounting my eeepc in my car and it just would be nice to have a means of recharging a netbook/notebook/mobile phone without all the extra wires from the various chargers.

^ hmm you have a point. i would bet that if you had something in your garage it would be possible to at least give your laptop to stay in sleep mode and not have to go to hibernate.

i apologize if you took this as a bash for your plans i was simply stating that for myself i would go another direction. Some applications this could be useful, but none that i see for myself. i would just as soon hook up a solar panel to charge a bank for me to power something.

On the other hand, the science behind it is just way cool. I love new and different things(even if the technology is old).

Sounds good. Just the way you worded it in the original post says you plan on powering the PC that way, not recharging it. I think people were trying to point out that induction for larger power requirements is not a common application.

it really is not all that complicated. The radio uses the same technology as wireless power. It would use frequency's just like the radio does. If you actually read the links with tesla, he invented radio. Macarroni used something like 27 of his patents when he "invented" it. The only part that was different, was tesla's was powered by the radio signal as well. The big problem with it is how to meter it. If its not in the power company's best interest, its not going to happen. Imagine people stealing your power the same way people steal you internet?
