    Universal chargers are all well and good, but until manufactures stop providing new universal charger with every device aren't people just going to have a draw full of them, instead of throwing the old charger out with the old device ?

    Nah, you end up in my situation: one charger per desk. I've actually bought extra chargers so I could do that... I'm that lazy.

    Oh, that could well come. We've already seen smartphones being sold sans-charger for that very reason, the 3DS XL comes without a charger, and Amazon's Kindle does the same. Give it a few generations of universality - assuming that anybody actually picks up the IEC's standard, which ain't a given - and manufacturers will make the cable optional, just like printer manufacturers did with parallel and later USB cables.

    Drawer* "draw" is a verb :)

    I am all for universal laptop chargers. As it is I have to keep spares for about 10 different types in the workshop just for troubleshooting and repairs. You would not believe the number of laptops which come in with chargers that are in bad enough shape to make me refuse to use them.

    With any luck this gets applied worldwide...

    And hopefully some MagSafe-like contraption we can all benefit from.

    Just how many laptops do you have to deal with? In my experience its fairly standard: 20V for Lenovo, 19.5V for Dells, 18.5V for HPs and 19V for other generics... Same connector withing manufacturers if you discount Ultrabook chargers as well...

    Here, have a .357 Magnum for the shooting.

    it could save money as well, "damn my charger has died, have to get a new one, oh wait, my old laptop had same end, maybe that will work"

    eventually, we wont need chargers for anything, as near field charging becomes the norm, with walls and floors having the fields built into them

    Yeah, I really hope that doesn't happen.

    I actually like the idea of wireless power

    Me too.

    The idea is good, but I simply don't see how it could be executed reliably

    Burns. Fire. Burns and fire everywhere. 100W is a lot of power to send over wirelessly, and with the sort of absorption human tissue/water has, you'll end up with second/third degree burns near instantly. Not to mention the arcing that will happen in normal electronics (thus frying them) or the EM interference to other stuff...

    Yeah, no. No wireless power past ~5W very short distance for me. And even those have issues already which mean I stick to cables eitherways.

    NB: This is all armchair physics, since I can't be arsed to do the math, but the concerns are real... And why we don't have wireless power for that matter.

    That isn't how inductive charging works, no electric current is passed through the air as it uses an alternating electromagnetic field. Inductive charging has already been used to power an entire room full of electronics.

    Radio waves are also alternating magnetic fields.

    Do you have any links on the roomful of stuff powered wirelessly? I'm interested in seeing what hallenges they had to overcome, how they did it and what the base tech they used is...

    I know it is tinfoil hat related speak, but still I can't help thinking of my home being turned in to a large-scale microwave oven. I don't like that thought.

    One of the company's are WiTricity Corp.

    And an article done by Computerworld gives a fairly good synopsis of it.

    No need for blood to be spilled, just a helpful correction :)

    Laptops need some sort of wireless charging imo, however the charging pad should be integrated into desks.

    Just plonk the laptop down, and it charges. It would be brilliant in schools, as the kids are useless at plugging them back in after they've used them, and the cabinets generally only charge them up for 2 hours overnight.
