Palm Pre: The First major phone with *Wireless Charging* !!

[amaga]

i saw this on that jimmy fallon show last night. godamn! i thought it was a joke or something! makes me want it real bad

its true,
n i reday abt it 4 years ago.this tecnology is under work since 19's.

Wireless charging or wired charging, we need electricity for that. My brother told me that the power crises in Karachi has become a serious issue already and we haven't even entered June yet. Bijli nahe hogi tu koi bhi cheez charge kaisay hoge mairay bhaiyon?

I am also worried about this issue man :-( and i don't think this technology will gonna work in pk

phi = BA :P..

e=- d(phi)/dt where e is the emf..

so if you have a magnetic field and another magnetic field cuts through it electrons move due to the force created by the interaction of the magnetic fileds :P.. if ur in alevels you are bound to know this..

udham!!!

show this to your desi fellers and they'll be like' china ka set waqaye maia acha hota hai'

Cool cell phone..........

man this wireless charging would be awesome for handheld consoles.....they should think onto that!

@ hasanj who told you this cOncePt????

Man both Primary and Secondary windings lies on same platform......and mostly these windings are used on Supplies to convert those AC in to Low Dc. you cannot put one winding on charger and other on brush....the brush starts charging when it was shorted with the Charger, which means when you place the brush on Charger stand then its connection completed ,through which the brush Charges.

i read the article here man
http://electronics.howstuffworks.com...ess-power1.htm

the thing ur taking about iz the basic implementation of Magnetic Induction like Step Up and Down Transformers
this idea iz not restricted to a few specific devices

Dude, I understand induction but doesn't that mean rather precise placements?

doesnt ur brush fit on its Stand in one place?
this also shows how ur brush charges WITHOUT Physical electrical contacts between Brush and Stand

That's what I said. For the toothbrush, it makes sense. But a free positioned mobile, that theory doesn't apply. No?

read tht article on teh link ive posted

its shows about a research by Students of MIT to make Magnetic Induction possible over long ranges
