Works for my toothbrush, why not?

Sonicare toothbrushes (teethbrushes?) can already do this, and there are a few other bathroom-type things (elec. razors) that have this capability. This allows the items themselves to be sealed, so you can drop it in the sink, etc. without destroying it.

Um...not quite sure what you are asking. There is nothing to short out...well, actually there is internally, but you just lay your device on it and it charges it inductively assuming that you have the SplashModule "receiver" inside your device to "receive wireless power".
Are you confusing conductive with inductive? Inductive is using EMF to transfer the power. I'm starting to see more and more things use inductive recharging systems. I've had a razor that used it as well as many electric cars use it I believe.

I'd be much happier carrying around ink cartridge (pen, not printer) sized plastic tubes of alcohol or hydrogen, as long as there are standard sizes. We've had AA, AAA, C, D and more for decades. I inderstand that portable devicees have their own special shape issues, but a single style of fuel cell would be a huge help.

... until everyone's head explodes from all the radiation.;)
I know you meant this in humor, but all this basically does is take a standard AC power transformer, and split it into two parts. The "primary" coil is in the charger unit, while the "secondary" coil is in the unit itself. Placing the two cores close to each other will complete the transformer.
I think it's great. If everyone can standardize on the specs, we can have a single charger for many items. Imagine only having to buy one car charger for all (most) of your portable devices.
This would NOT be a good idea for something that is magnetically sensitive, as it would effectively erase floppy/hard disks, cassette tapes, etc...
The "radiation" would be the same that you'd get from any standard "wall wart" plug-in transformer.

I've had one of these for a tablet PC for over 10 years now. Toshiba released one for doctors for their tablet PC's back in the mid 90's
Got it with an auction I won that had 20 of those 486 tablet Pc's that used wacom tablets behind the screens for the pointer. Neat device.
Do not look at laser with remaining good eye.
Well that's not likely, but people with pacemakers are likely to fall over dead if they get too close to one of these mats.
Pacemaker + powerful EM field = powerful EM field + corpse.
I have no idea how close too close would be though...
Charging by magnetic induction. They say, "like magic or something"... Har har. Kinda cool:

MobileWise has a similar product.
I saw both of these reviewed on TechTV because they were at the CES show a couple of months back.
They seem pretty cool but I really do not want to see the pricetag.

Motorola developed an alcohol-based battery replacement in early 2000, but no word since then.

Nikola Tesla proposed this around 1890 or so.
