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

**hexxamillion** · 03-21-2009, 02:53 AM

This is the next soon to be big craze for mobile devices. Some of you may have already seen these posts throughout the internet and this solution is still in it infancy. I preordered a evaluation unit. This is already done in Japan with the Wii Remote and I can't wait for that to hit the US. I plan wo use this for powering my EEEPC CarPC. This may be another enhancement to my work in progress. See my project post:http://www.mp3car.com/vbulletin/work...box-mount.html

Check it out!

Interesting to see this technology actually being deployed over 100 years after it's discovery:

Nicola Tesla also had an obsession with trying to power things wirelessly...

And he also observed unusual signals that he later thought may have been evidence of extraterrestrial radio communications coming from Venus or Mars.

Tesla suceeded with the broadcast power, one of his many achievements:

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

We did a video of this technology at CES this year.

Yep this is definitely far from a new idea..going back to the 1800's. It's just nice to finally see this moving along and soon to consumers.

Japan already has this for the Wii Remote which is the other thing I need because I use the Wii remote in my car.

Isn't the efficiency rate for this close to 1%?

**Flaring_Afro** · 03-22-2009, 12:48 AM

^ i dont know if its that low but im sure its horrible or more things would use this as it would be a huge solution for many things like outlets for home theater etc. and in our cars efficiency is very important.

then again im too ADD to read most of the links above lol

One problem I see with this is safety.

In a house, if your laptop catches fire or something, usually a saftey device (breaker) in your house will flick off, with this, I can't see that happening.

This is indeed a very old technology.

My Braun Electric Toothbrush gets charged inductively... NO electrical contacts!

But I'd imagine the efficiency is pretty low. This may be a good replacement for mobile chargers, but taking it to laptops may be very lossy on the efficiency front.
