    Wireless electricity was invented/discovered by Nikola Tesla.. What took so long to get products using this to consumers?

    History behind it

    It's been in rechargeable toothbrushes for over a decade now. The question is "what took so long to get it into consumer electronics?"

    Because if you think about it, it's really too much hassle for such little improvement. Toothbrushs must have it in order to be fully water tight.

    Hassle to have universal charging for ALL devices? Hassle to have charging pads built into furniture, available on planes and trains, in hotels and so on. A hassle to not have to carry multiple adapters and cables when you travel or just reducing the clutter of cables around the house. A nice pad on your desk or bureau where all your devices can sit and charge by utilizing just one electrical outlet.

    Imagine traveling with just one pad so you can charge your phone, razor and toothbrush.

    How much money do you think people spend in home and car chargers when they buy new devices or lose their current adapter? I had to drop $45 for a $5 Palm charger when I was in Vegas because one of the contacts broke on the adapter. Wouldn't have anything to break if it was just sitting on a pad.

    Yeah, you're right. Such a hassle.

    In fact, there is a form of wireless electricity in every single consumer electronics device: the transformer. Yes, those all use two inductive coils (with different numbers of windings) to step down voltage from 100ish volts to 10ish volts without impressive losses. In between the coils, the energy is passed via a magnetic field, aka wirelessly.

    Slow down there son, there are still lots of details that aren't standardized yet (aligning magnet location/polarity, coil location/size, magnetic flux, etc.) Given that it took cell phones almost 20 years to standardize the charger connection (which is still in the future btw), we should see universal induction charging standards by 2029

    This used to ring more true in years past; most power supplies now days use switching power supplies to step down the 115V source (reduces weight, and the possible annoying hum.)

    I can charge my toothbrush with my Panashonice shaver charger and vice versa.

    Magnet location? The only reason for magnets on the touchstone is because of their stupid angled design with no lip. Put a curved lip on it and you could rest the Pre on it in portrait or landscape mode with no magnets needed.

    If you bought a pad from WildCharge I could place my Pre, toothbrush and shaver anywhere on the pad and all three would charge.

    Speed up son...

    Well, you learn something new every day. Thanks for the knowledge enhancement.

    Oh come on, they have 3rd party attachments even for the iPhone, iPod, and Blackberries, Cameras, etc that you snap on and get this same function. It's a charging base that you just sit the device with this attachment on and BAM, you got charging. Don't give me that..

    I remember reading that one was inductive and the other conductive--which IIRC are not compatible. I know that the WildCharge adapters for a Razr/iPhone/BlackBerry have exposed contacts, vs. the under-the-surface ones for the Touchstone or for a toothbrush that charges this way.

    Why did it take so long? Because proprietary power connectors tended to be major revenue streams.

    But the pre's charger is not universal nor is it clear (or likely) the pre will work on a universal charger. Right now standards on inductive wireless chargers are non existant. I have a couple of inductive charging devices and they don't work with each other.

    So one could say universally that deductive reasoning should and would induce a magnetic charge - existentially anyway ...

    Aw forget it, I'm lost. I'm movin' to a different thread before I stunt my growth.

    This sparked an idea in me head... I wonder if the Pre would charge via a toothbrush charger?
    Palm History: Palm III>IIIc>CLIÉ NR70v>CLIÉ TG50>Tungsten C>Treo 650>Treo 700p>Centro>Pre!! 6/5/09

    Sorry Timmy, SERO does not work with the Pre.

    Ease of the gas a little, dad.

    I suggest you take a look at the output voltages on the charges in your house. I've got chargers that put out anywhere from 3 volts to 18.5 (yes, point 5) volts, and at least half a dozen different levels in between, for my electronic devices. Even if all of the vendors of electronics eventually come out with inductive charging for their devices, it'll be a cold day in he!! before you see anything resembling a universal standard for voltage, current, and inductance, much less a standard physical implementation.

    I can easily imagine that in 5 years, you'll no longer be carrying half a dozen plug-in chargers with you on a trip. Instead, you'll be carrying half a dozen inductive chargers, each incompatible with the rest.

    a universe charging pad would be nice if it was big enough you could even charge a laptop while using it so you don't have to plug it in so its easy to "run". And that means no more miss connecting which laptops get after a while where the charger plug wont charge properly because it is not connecting right.

    If this is only $49.99, then the Touchstone shouldn't be any more than that. And heck, you can charge two Wiimotes with this!

    To me, the Touchstone is, at this point, just a gee-whiz feature that differentiates the Pre from other devices, but at a significant cost. And when I say that, I mean it's on purpose. I don't think Palm really expects to sell all that many (if the price is really the rumored $69.99; if it's more like $29.99, then I take all of this back), and something about it tells me it wasn't easy to produce in such a small, integrated package.

    I think the idea is to get the trademark out there, let the earliest adopters pay through the nose for the thing to subsidize it, and then later more Touchstone accessories will be introduced, the investment recouped, and the price will go down.

    Just more idle speculation from a Pre-occupied freak.
